Request is blank when sending data through iOS to google cloud endpoint - ios

i am working on Google cloud endpoint with datastore. When i am passing data through Android & iOS with method POST , it is getting saved in datastore with empty record. i.e. request is properly working but the way i am sending data is wrong. please help me for this.
For iOS, code is mentioned below :
NSDictionary *headers = #{ #"content-type": #"application/json",
#"cache-control": #"no-cache",
#"postman-token": #"404012ff-722e-c5d8-48db-fa7fb3260841"};
NSLog(#"header %#",headers);
request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"enter url here..."]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
NSString* strRequest=#"";
strRequest =[[NSString alloc] initWithFormat:#"displayEmail=%#&displayName=%#",#"sonal#gmail.com",#"sonal"];
NSLog(#"url is %# parameter = %#", request , strRequest);
[request setHTTPMethod:#"POST"];
[request setHTTPBody: [strRequest dataUsingEncoding:NSUTF8StringEncoding]];
[request setAllHTTPHeaderFields:headers];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *responseBody = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"responce Body===>%#",responseBody);
if (error) {
NSLog(#"%#", error);
} else {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
NSLog(#"responce%#", httpResponse);
}
}];
[dataTask resume];

You need to set the httpBody property of your request. If you don't provide a body for the POST, of course it's blank.
https://developer.apple.com/reference/foundation/nsmutableurlrequest/1409064-httpbody
Or Objective-C
https://developer.apple.com/reference/foundation/nsmutableurlrequest/1409064-httpbody?language=objc

We got a solution..
we changed the way of passing data..
here is code :
request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:syncURL]
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60];
NSData *requestData = [NSData dataWithBytes:[serverSyncAPIRequestJSON UTF8String] length:[serverSyncAPIRequestJSON length]];[request setHTTPMethod:#"POST"]; [request setHTTPBody:requestData]; [request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];

Objective c post request is not working

I have looked at a lot of posts about http post requests and I still have not been able to find the answer. My problem is that I need to send one string to my work partners website so it can be accessed using a GET request and used for a leader board/
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[req setHTTPMethod:#"POST"];
NSData *postData = [revs dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
[req addValue:postLength forHTTPHeaderField:#"Content-Length"];
[req setHTTPBody:postData];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:req
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Do something with response data here - convert to JSON, check if error exists, etc....
NSLog(response.description);
// NSLog([[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]);
}];
[task resume];
But the request never goes to the website, it is called ../distances.txt
Can anyone help?

How to fetch Data from the web services using NSURLSession?

I have made one demo code for print the data from the web Services,

[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

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)

Objective c post request not sending the data

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];

how to pass a dictionary using NSURLSession in post method?

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];
