I have made one demo code for print the data from the web Services,
Code
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://54.149.46.64/API/video.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"video" forHTTPHeaderField:#"list"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
}] resume];
Output
JSON_Webservices[4496:150468] requestReply: {"Status":"Fail","Message":"Please enter required fields"}
Why i am not able to fetch data from the WS? Please help me.
Working Fine In Postman

Thank You.

I have a button of submitting form data to the service. When user click it it submit data and give alert of success. I want to add activity indicator in it , when user click button of submit the time it takes to submit the data the activity indicator should move and than hide when it data is submitted.I'm confused where should i use it in the code , I'm confused at that whether it shall be call after response or anywhere else. My code is,
NSString *post = [NSString stringWithFormat:#"propertyfor=%#&propertytype=%#&landarea=%#&country=%#&city=%#&price=%#&description=%#&location=%#&name=%#&email=%#&phone=%#",_propertyfor,_propertytype,_landarea,_country,_city,_price,_propdes,_propdescrip,self.name.text,self.email.text,phone];
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:#"My URL"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
}] resume];
**//Start Activity Indicator here.**
NSString *post = [NSString stringWithFormat:#"propertyfor=%#&propertytype=%#&landarea=%#&country=%#&city=%#&price=%#&description=%#&location=%#&name=%#&email=%#&phone=%#",_propertyfor,_propertytype,_landarea,_country,_city,_price,_propdes,_propdescrip,self.name.text,self.email.text,phone];
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:#"My URL"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
**//Stop Activity Indicator here.**
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
}] resume];
You need to start animating before session created and stop animating one you get reply. In your code :
.
.
.
.
[activity startAnimating];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
dispatch_async(dispatch_get_main_queue(), ^{
[activity stopAnimating];
});
NSLog(#"requestReply: %#", requestReply);
}] resume];
Replace followind code with original:
CGSize s1 = UIApplication.sharedApplication.windows[0].frame.size;
CGRect r1 = CGRectMake(s1.width/2-20, s1.height/2-20, 40, 40);
UIActivityIndicatorView *act = [[UIActivityIndicatorView alloc]initWithFrame:r1];
[self.view addSubview:act];
[act startAnimating];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
[act stopAnimating];
[act removeFromSuperview];
}] resume];
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"];

NSData *dataToPost = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:nil];
NSData *final =[dataToPost AES256EncryptWithKey:#"02b6e206868660a0d59d2e51a11fdcd6"];
//
NSLog(#"postData1e == %#",final);

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:

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)
This is my code by which i am posting data in url.

Try the code in this gist I created
Which is generated using PAW .
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];
