I am sending some data to my server using POST method. Code is as follows:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"<myServer ip>"]];
[request setValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPMethod:#"POST"];
NSString *stringData = #"Hello";
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPBody = requestBodyData;
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[conn start];
I am not receiving the correct data in from the server.
The code for receiving is:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSLog(#"didFinishLoading Called");
NSString* newStr = [[NSString alloc] initWithData:responseData
encoding:NSUTF8StringEncoding];
NSLog(#"data received is = %#",newStr);
}
The response I receive is:
<soapenv:Body>
<soapenv:Fault>
<faultcode xmlns:ns1="xml.apache.org/axis/">ns1:Client.NoSOAPAction</…;
<faultstring>no SOAPAction header!</faultstring>
<detail>
You can't just test a SOAP service by sending an arbitrary string. All you are proving is that the URL is pointing to a server which is expecting to receive SOAP messages. You need to look at the server specification and create the appropriate SOAP payload to be sent. This should replace your current content in stringData.

I know this question was asked before. And my code is basically utilizing that and some other post here. However I am receiving an error where the page is not found in the response data.
-(void)sendToForm{
whereString = whereField.text;
nameString=name.text;
phoneString=phone.text;
emailString=email.text;
dateChoice = dateLabel.text;
serviceChoice = whatLabel.text;
//initialize new mutable data ***I DONT SEE WHAT THE POINT OF THIS IS
NSMutableData *data = [[NSMutableData alloc] init];
//THIS GIVES me an error, received data is not defined anywhere
// self.receivedData = data;
//initialize url that is going to be fetched.
NSURL *url = [NSURL URLWithString:#"https://docs.google.com/forms/d/1jeyxQYlgIUylhXnZZEcy6BC2dx_2AUB3qSNuCqFHUDU/viewform"];
//initialize a request from url
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[url standardizedURL]];
//set http method
[request setHTTPMethod:#"POST"];
//initialize a post data
NSString *postData = [NSString stringWithFormat:#"entry.1550955212=%#&entry.935955213=%#&entry.1547576233=%#&entry.202631922=%#&entry.1387567225=%#&entry.1031369018",serviceChoice,dateChoice,whereString,emailString,phoneString,nameString]; //set request content type we MUST set this value.
[request setValue:#"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
//set post data of request
[request setHTTPBody:[postData dataUsingEncoding:NSUTF8StringEncoding]];
//initialize a connection from request
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
//start the connection
[connection start];
}
I have some functions checking the connection and response and they all work. but in the response data it returns as Page Not Found
Needed to be formResponse instead of viewForm
Good day,
I am trying to use a Codeigniter based API to connect with iOS and using NSURLRequest.
The API is in debugMode and for now it returns the same key value pair as json as the one that you are posting. I have tried posting the values to the link through postman and it works correctly, however when I post it through my iOS application, the json response is received but the array that should contain the post values is empty.
Here is the iOS Code snippet :
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#",BASEURL,service]];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSString * params = #"authkey=waris";
NSData * postData = [params dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];;
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postData];
NSLog(#"Posting : '%#' to %#",params,url);
[connection start];
This is the response when I post the same parameters through postman ( A RESTFUL Client for Chrome )
{
"status": "1",
"data": {
"authkey": "warisali"
}
}
However when I query the same API from the above iOS Code I am getting this :
{
data = 0;
status = 1;
}
Any help on the matter will be highly appreciated!
I had same issue (not with CodeIgniter but with Ruby ...)
Try something like this, solved my problem.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#",BASEURL,service]];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSDictionary *paramDict = #{#"authkey": #"waris"};
NSError *error = nil;
NSData *postData = [NSJSONSerialization dataWithJSONObject:paramDict options:NSJSONWritingPrettyPrinted error:&error];
if (error)
{
NSLog(#"error while creating data %#", error);
return;
}
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];;
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postData];
NSLog(#"Posting : '%#' to %#",params,url);
[connection start];
I ended up using the ASIHttpRequest + SBJson combo and that worked like Charm!
After adding the ASIHttpRequest core classes and SBJson Classes to parse the JSON, I was able to achieve what I wanted !
The problem is that because of the way you're creating the connection, it will start immediately, before you've finished configuring the request. Thus, you're creating a mutable request, creating and starting the connection, then attempting to modify the request and then trying to start the request a second time.
You can fix that by changing the line that says:
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
To say:
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];
Or, easier, just move the original instantiation of the NSURLConnection (without the startImmediately:NO) after you've finished configuring your request, and then eliminate the [connection start] line altogether.
For Android, I've been able to send POST requests in the following way:
HttpClient http = new DefaultHttpClient();
HttpPost request = new HttpPost("https://somewebsite.com");
request.setEntity(new StringEntity(data));
http.execute(request);
However, on iOS I get the following error:
NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9843)
What is the best way to perform a synchronous POST request using https on iOS?
You can try this function:
-(NSData *)post:(NSString *)postString url:(NSString*)urlString{
//Response data object
NSData *returnData = [[NSData alloc]init];
//Build the Request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)[postString length]] forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
//Send the Request
returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];
//Get the Result of Request
NSString *response = [[NSString alloc] initWithBytes:[returnData bytes] length:[returnData length] encoding:NSUTF8StringEncoding];
bool debug = YES;
if (debug && response) {
NSLog(#"Response >>>> %#",response);
}
return returnData;
}
And here is how you use it:
NSString *postString = [NSString stringWithFormat:#"param=%#",param];
NSString *urlString = #"https://www.yourapi.com";
NSData *returnData = [self post:postString url:urlString];
Edit:
I found the error code in the source code:
errSSLHostNameMismatch = -9843, /* peer host name mismatch */
The problem should be address on your server.
And here is from the docs:
errSSLHostNameMismatch -9843 The host name you connected with does
not match any of the host names allowed by the certificate. This is
commonly caused by an incorrect value for the kCFStreamSSLPeerName
property within the dictionary associated with the stream’s
kCFStreamPropertySSLSettings key. Available in OS X v10.4 and later.
hope this help
I've search and try many different solutions but without luck.
I am trying to make a JSON Request to my server, it works for sure because I've tested it in PHP (simple call, it receives string name and string password and check into the database if the user is correct). The request should receive back a JSON with property "success" only (which could be "true" or "false").
Here is my code:
- (void)logonService:(NSString *) name widthArg2:(NSString *) password {
// Create the request.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://46.51.169.145/ios/index.php/user/login/"]];
// Specify that it will be a POST request
request.HTTPMethod = #"POST";
//setting json fields
[request setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
//prepare output data
NSString *in1;
NSDictionary *outputData = [NSDictionary dictionaryWithObjectsAndKeys:in1, #"success", nil];
NSError *error = nil;
NSData *jsonOutputData = [NSJSONSerialization dataWithJSONObject:outputData options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonOutputString = [[NSString alloc] initWithData:jsonOutputData encoding:NSUTF8StringEncoding];
//set json string to body data
NSData *requestInputBodyData = [jsonOutputString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody: requestInputBodyData];
//prepare input data
NSString *input = [NSString stringWithFormat:#"&name=%#&password=%#",name,password];
//Encode the post string using NSASCIIStringEncoding and also the post string you need to send in NSData format.
NSData *inputData = [input dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
//calculate length of post data
NSString *inputLength = [NSString stringWithFormat:#"%d",[inputData length]];
//Set HTTP header field with length of the post data.
[request setValue:inputLength forHTTPHeaderField:#"Content-Length"];
//encode type
//[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
//add it to http body
[request setHTTPBody:inputData];
// Create url connection and fire request
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(conn){
NSLog(#"Connection Successful");
}else{
NSLog(#"Connection could not be made");
}
}
The delegate DidReceiveData fires correctly but the result is always NIL:
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
NSString *jsonResponseData = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSLog(#"RESULT1: %#", jsonResponseData);
[_responseData appendData:data];
}
Thank you, hope someone can help me!
thanks a lot for the comments, I finally fix it, and after that I decided to starting using a JSON library --> https://github.com/stig/json-framework/
This is how I finally have the code:
//prepare connection
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#user.php", _urlServer]];
NSMutableDictionary *data = [[NSMutableDictionary alloc] init];
[data setObject:#"login" forKey:#"action"];
[data setObject:username forKey:#"username"];
[data setObject:password forKey:#"password"];
//start connection
// Create the request, if there is a connection going on just cancel it.
[_connection cancel];
//initialize new mutable data
NSMutableData *receivedData = [[NSMutableData alloc] init];
_receivedData = receivedData;
//initialize the url which will be fetched
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[url standardizedURL]];
//set http method
[request setHTTPMethod:#"POST"];
//initialize a post data
NSString *dataString = [[NSString alloc] init];
for(id key in data) {
id value = [data objectForKey:key];
//keys string
NSString *newData = [NSString stringWithFormat:#"&%#=%#", key, value];
dataString = [dataString stringByAppendingString: newData];
}
//set request content type we MUST set this value.
[request setValue:#"application/x-www-form-urlencoded;charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
//set post data of request
[request setHTTPBody:[dataString dataUsingEncoding:NSUTF8StringEncoding]];
//initialize a connection from request
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
_connection = connection;
//NSLog(#"Sending request with parameters: %#", dataString);
//begin the connection
[_connection start];
And its working like a charm. Next step is to authenticate somehow, right now connection is open to the world.
Iam sending JSON Object request to the server but server returns Status Code 405. how to solve this problem. please any one help me.
My code :
+(NSData *)GpBySalesDetailed:(NSMutableDictionary *)spDetailedDict{
NSLog(#"spDetailedDict:%#",spDetailedDict);
NSString *dataString = [spDetailedDict JSONRepresentation];
NSLog(#"%#dataString",dataString);
return [dataString dataUsingEncoding:NSUTF8StringEncoding];
}
-(void)requestWithUrl:(NSURL *)url WithJsonData:(NSData *)JsonData
{
NSMutableURLRequest *urlRequest=[[NSMutableURLRequest alloc]initWithURL:#"http://srbisolutions.com/SmartReportService.svc/GpBySalesPersonDetailed];
if (JsonData != nil) {
[urlRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:JsonData];
}
else
{
[urlRequest setHTTPMethod:#"GET"];
}
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self startImmediately:YES];
[conn start];
}
HTTP Code 405 means "Method not allowed", it does not accept a post request for this particular URI. Either the server must be configured to accept POST requests or it should offer another URI.
try this
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:YOURURL
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10.0 ];
NSLog(#"final request is %#",request);
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
//Here postData is a Dictionary with key values in web services format use ur own dic
[request setHTTPBody:[[self convertToJSON:postData] dataUsingEncoding:NSUTF8StringEncoding]];
NSString *contentLength = [NSString stringWithFormat:#"%d",[[request HTTPBody] length]];
[request setValue:contentLength forHTTPHeaderField:#"Content-Length"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection)
{
self.responseData = [NSMutableData data];
}
//============JSON CONVERSION========
