I'm trying to post new data to a ws but im geting error each time
I need to
1-pass a username and password each time
2-code the data with AES256 WITH THE API KEY
Code:
- (IBAction)AddTicket:(id)sender {
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSURL *URL = [[NSURL alloc] initWithString:#"http://dev.enano-tech.com/api/Ticket"];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:#"1",#"id",#"1",#"idProject",#"1",#"idTicketType",#"nameo",#"name",#"nameo",#"description", #"1",#"idStatus",#"2016-06-23 15:20:49",#"creationDateTime", nil];
NSData *dataToPost = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:nil];
NSData *final =[dataToPost AES256EncryptWithKey:#"02b6e206868660a0d59d2e51a11fdcd6"];
//
NSLog(#"postData1e == %#",final);
NSLog(#"final %#",dataToPost);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request setHTTPMethod:#"POST"];
[request addValue:#"CURLAUTH_BASIC" forHTTPHeaderField:#"CURLOPT_HTTPAUTH"];
[request addValue:#"Basic YWRtaW46YWRtaW5hZG1pbg==" forHTTPHeaderField:#"authorization"];
[request addValue:#"admin:adminadmin" forHTTPHeaderField:#"CURLOPT_USERPWD"];
[request addValue:#"true" forHTTPHeaderField:#"CURLOPT_RETURNTRANSFER"];
[request addValue:#"false" forHTTPHeaderField:#"CURLOPT_SSL_VERIFYPEER"];
[request addValue:#"POST" forHTTPHeaderField:#"CURLOPT_CUSTOMREQUES"];
[request addValue:#"true" forHTTPHeaderField:#"CURLOPT_POST"];
[request addValue:#"false" forHTTPHeaderField:#"CURLOPT_POSTFIELDS"];
[request setHTTPBody:final];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *result = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSString *str = [[NSString alloc]initWithData:final encoding:NSUTF8StringEncoding];
NSLog(#"data %#",data);
NSLog(#"respoce %#",response);
NSLog(#"result == %#",result);
}];
[postDataTask resume];
}
Response:
2016-08-02 15:06:47.768 Projector[3936:1619429] result == {"error":"invalid API query", "message":"'data' is not correctly encoded for method POST. Request for correct API KEY"}
this is the documentation of api:
enter image description here
Your webserver is missing "data" from the website. To fix it, you'll need to add that field to your form or find the correct field name (case sensitive)

I am trying to create a login screen where one has to enter his UserName and Password. On clicking the login button I am parsing the details to the server. Here's the code
NSString *post = [NSString stringWithFormat:#"username=%#&password=%#",[_userNameText text],[_passwordText text]];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu" , (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://*******/*****/******/userLogin.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"sample data"];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data , NSURLResponse *response , NSError *error){
_requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"%#",_requestReply);
}] resume];
So far the code works just as intended. Now I want to check if the "requestReply" that is returned from the server has the value "success" for it's "status" key. So I tried to print it's value with the following code.
_responseData = _requestReply;
NSLog(#"%#" , _responseData[#"status"]);
And here's the console output
2016-10-21 06:44:03.424 QuizApp2[65724:1287972] (null)
2016-10-21 06:44:03.501 QuizApp2[65724:1288003] {"status":"success","message":"Welcome admin","code":true}
I am not sure, but I felt that the last line of the code is executing before the parsing happens. Can someone please highlight how the control flows here? Or is there anything wrong with my code?
I didn't see any code about parse data. Do you mean this line
_requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
If the userLogin.php returns a JSON data, just do this:
[[session dataTaskWithRequest:request completionHandler:^(NSData *data , NSURLResponse *response , NSError *error){
NSError *err = nil;
id jsonData = [NSJSONSerialization JSONObjectWithData:data options:0 error:&err];
if (err) {
NSLog(#"%#", err);
}
else {
NSLog(#"%#", jsonData[#"status"]);
}
}] resume];
I have tried this methods, I want to know about integration of rest API in iOS.
I want to know about JSON parsing in web services. I know about these methods but how to use it? but what is function of each method?
This IBAction method sends request string for signup to the server .
-(void)genSignup
{
responseData = [NSMutableData data];
urlLoc= [urlLoc stringByAppendingString:service];
NSLog(#"%#",requestString);
NSData *postData = [requestString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlLoc]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
//NSLog(#"%#",request);
PostConnectionRegisterGenUser = [[NSURLConnection alloc] initWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[responseData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[MyClass removePregressIndicator:self.view];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[MyClass removePregressIndicator:self.view];
if (connection == PostConnectionRegisterGenUser)
{
NSError *error;
NSDictionary *results = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSLog(#"%#",results);
}
}
how to use it?
NSURLConnection is deprecated effective Mac OS 10.11 and iOS 9. So, at this point NSURLSession should be used instead of NSURLConnection.
I just add NSURLSession in your code. Change Key, URL accordingly. I did not compile it.
NSString * requestString = [NSString stringWithFormat:#"Name=%#&Email=%#&Password=%#&MobileNumber=%#&BloodGroup=%#&DeviceID=%#&City=%#&DeviceType=I",txtName.text,txtEmail.text,txtPassword.text,txtMobileno.text,strBlood,strDeviceID,txtCity.text];
NSData *postData = [requestString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlLoc]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{ #"api-key": #"API_KEY"};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURLSessionDataTask *sessionPostDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// The server answers with an error because it doesn't receive the params
}];
[sessionPostDataTask resume];
Do let me know if you need any other information.
Hope this will help you !!!
Use simple common methods for NSURLSession WS Calling.
-(void)callWebserviceWithParams:(NSDictionary *)aParams withURL:(NSString *)aStrURL withTarget:(UIViewController *)aVCObj withCompletionBlock:(void(^)(NSMutableDictionary *aMutDict))completionBlock withFailureBlock:(void(^)(NSError *error))failure
{
NSString *aStrParams = [self getFormDataStringWithDictParams:aParams];
NSData *aData = [aStrParams dataUsingEncoding:NSUTF8StringEncoding];
aStrURL = [aStrURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *aRequest = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:aStrURL]];
[aRequest setHTTPMethod:#"POST"];
[aRequest setHTTPBody:aData];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
[aRequest setHTTPBody:aData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:aRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//
if (error ==nil) {
NSString *aStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"ResponseString:%#",aStr);
NSMutableDictionary *aMutDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
aMutDict = [aMutDict dictionaryByReplacingNullsWithBlanks];
dispatch_async(dispatch_get_main_queue(), ^{
completionBlock(aMutDict);
});
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
failure(error);
});
}
}];
[postDataTask resume];
}
-(NSString *)getFormDataStringWithDictParams:(NSDictionary *)aDict
{
NSMutableString *aMutStr = [[NSMutableString alloc]initWithString:#""];
for (NSString *aKey in aDict.allKeys) {
[aMutStr appendFormat:#"%#=%#&",aKey,aDict[aKey]];
}
NSString *aStrParam;
if (aMutStr.length>2) {
aStrParam = [aMutStr substringWithRange:NSMakeRange(0, aMutStr.length-1)];
}
else
aStrParam = #"";
return aStrParam;
}
Use Like This
NSDictionary* param = #{
#"Key1":#"Value1",
#"Key2":#"value2"
};
[self callWebserviceWithParams:param withURL:#"URL String" withTarget:self withCompletionBlock:^(NSMutableDictionary *aMutDict) {
//code For Success
} withFailureBlock:^(NSError *error) {
// code for WS Responce failure
}];
also you have to set this method in NSObject Class and make it simple and used in whole app.
Another option Nsurlsession:
-(void)Fetchdata
{
NSURLSessionConfiguration *defaultSessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultSessionConfiguration];
// Setup the request with URL
NSURL *url = [NSURL URLWithString:#"http://52.2/category_list.php"];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
// Convert POST string parameters to data using UTF8 Encoding
NSString *postParams = #"admin_id=19";
NSData *postData = [postParams dataUsingEncoding:NSUTF8StringEncoding];
// Convert POST string parameters to data using UTF8 Encoding
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:postData];
// Create dataTask
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSDictionary *results = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"%#",results);
arryTempdata = [[results valueForKey:#"message"] valueForKey:#"banner"];
NSLog(#"%#",arryTempdata);
tblV.reloadData;
}];
// Fire the request
[dataTask resume];
}
Good day.Im trying to send simple post data to server.This is the code how i do it.
-(void)makeRequest:(NSString*)stringParameters{
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:#"http://vaenterprises.webatu.com/Authentication.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:#"application/text" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"application/text" forHTTPHeaderField:#"Accept"];
[request setHTTPMethod:#"POST"];
NSString* postData = #"tag=hello&username=yo&something=something";
[request setHTTPBody:postData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
[self parseJson:data];
}];
[postDataTask resume];
}
It looks great till i echo the whole post from php side like this
echo json_encode($_POST);
and i print the result in the iOS like this
-(void)parseJson:(NSData*) data{
NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSError *jsonError = nil;
NSDictionary* jsonObject= [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError];
NSLog(#"%#",myString);
}
this issue is that i get empty string..so it means that post data not being send and that is 10000 percent objective c side issue and i have no clue why its so as in this method we only got setHttpBody with the actual string which contains key and value separated by & but that data not being send as you can see.So what am i doing wrong?Please tell somebody
Http body has to be of type NSData. Try out following code
NSString* stringData = #"tag=hello&username=yo&something=something";
NSData* data = [stringData dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
I am fetching data using POST method. And I have successfully retrieved all the data.It's taking too long to display it in UI but I can print it immediately on console, my code is
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://www.xxxyyy.com/v1/api/client/authorize"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"ABCD" forHTTPHeaderField:#"Authkey"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
[request setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"Authkey"];
NSData* data1 = [requestReply dataUsingEncoding:NSUTF8StringEncoding];
jsonReturnArray = [NSJSONSerialization JSONObjectWithData:data1 options:NSJSONReadingAllowFragments error:&error];
NSArray *array = [jsonReturnArray copy];
[self rec:array];
NSString *phoneNumber=[NSString stringWithFormat:#"%#",[jsonReturnArray valueForKey:#"phone"]];
lblPhoneNumber.text = phoneNumber;
NSString *Address=[NSString stringWithFormat:#"%# %# %#,CA %#",[jsonReturnArray valueForKey:#"street1"],[jsonReturnArray valueForKey:#"street2"],[jsonReturnArray valueForKey:#"city"],[jsonReturnArray valueForKey:#"postalcode"]];
lblAddress.text=Address;//takes long time to display
NSLog(#"%#",Address);//immeaditely print
strlatitude=[jsonReturnArray valueForKey:#"latitude"];
strlongitude=[jsonReturnArray valueForKey:#"longitude"];
[self Map:(MKMapView *)mapLocation didUpdateUserLocation:(MKUserLocation *)nil];//method call
}] resume];
This is take too time to print data, but if you use NSURLConnection class it may be help you.This is my Class method it may be helpful.
+ (void)postRequestData:(NSDictionary *)postVars
Action:(APIMode)action
WithCompletionHandlar:(void (^) (id result, BOOL status))completionBlock
{
NSURL *url = [NSURL URLWithString:API_URL([self getAPINameForType:action])];
NSLog(#"Request URL %#",[NSString stringWithFormat:#"%#",url]);
NSString *contentType = #"application/json";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSError *err = nil;
NSMutableDictionary *params=[[NSMutableDictionary alloc] initWithDictionary:postVars];
// [params setObject:[self getAPINameForType:action] forKey:#"mode"];
NSLog(#"Paramater %#",params);
NSData *body = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&err];
[request setHTTPBody:body];
[request addValue:[NSString stringWithFormat:#"%lu", (unsigned long)body.length] forHTTPHeaderField: #"Content-Length"];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError)
{
if(!connectionError)
{
NSError *error = nil;
NSDictionary *dictResponse = [NSDictionary dictionaryWithDictionary:[NSJSONSerialization JSONObjectWithData:data
options:NSJSONReadingAllowFragments error:&error]];
dispatch_async(dispatch_get_main_queue(), ^{
completionBlock(dictResponse,(error == nil));
});
NSLog(#"%#",dictResponse);
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
completionBlock(connectionError.localizedDescription,NO);
});
}
}];
}
Use this method instead of it.It is executed fast because NSURLConnection Class execute in background.
Try to fetch your data using NSURLConnection class(manual code) or simply use AFNetworking class(less code). AFNetworking internally uses NSURLConnection class itself.
I do not know how to pass values in dictionary into server using NSURLSession via POST. Please help me to solve this problem.
My dictionary contains contact information (name and phone number only), where the key is the person's name and the value is their phone number.
I have sample code using nsurl connection - how can I convert it to use NSURLSession?
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://holla.com/login"]];
request.HTTPMethod = #"POST"; [request setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:#"212333333",#"ABCD",#"6544345345",#"NMHG", nil];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil];
request.HTTPBody = jsonData;
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
I solve the problem by using the following method:
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL * url = [NSURL URLWithString:[ NSString stringWithFormat:#"http://xxxx.com/login/save_contact"]];;
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPMethod:#"POST"];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys:#"212333333",#"ABCD",#"6544345345",#"NMHG",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
if(error == nil)
{
NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog(#"Data = %#",text);
}
}];
[postDataTask resume];
