ios - AFNetworking POST Request failed Code=-1011 (400) -

i have webservice , can make post calls via postman utility. on postman settings

i using afnetworking. code:

afhttprequestoperationmanager *manager = [afhttprequestoperationmanager manager]; nsdictionary *parameters = @{@"offset": @"1", @"csrf-token": @"63b164ea557b4aba694f81520c71972fa43a9772"}; manager.requestserializer = [afjsonrequestserializer serializer]; [manager post:@"http://simple.com/" parameters:parameters success:^(afhttprequestoperation *operation, id responseobject) {     nslog(@"json: %@", responseobject); } failure:^(afhttprequestoperation *operation, nserror *error) {     nslog(@"error: %@", error); }]; 

but error:

error: error domain=com.alamofire.error.serialization.response code=-1011 "request failed: bad request (400)" userinfo=0x7a6c5240 {com.alamofire.serialization.response.error.response=<nshttpurlresponse: 0x7a6b5360> { url: http://simple.com/ } { status code: 400, headers {     "cache-control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0, private, must-revalidate";     connection = "keep-alive";     "content-encoding" = gzip;     "content-type" = "text/html; charset=utf-8";     date = "sun, 31 may 2015 15:40:26 gmt";     expires = "thu, 19 nov 1981 08:52:00 gmt";     pragma = "no-cache";     server = "nginx/1.6.2";     "set-cookie" = "csrf-token=5589461e87b28a538953ccac4168bf1f98b20b1ds%3a40%3a%22f52bda5262260a3ee0a10efcf48a6a49c11e4103%22%3b; path=/, phpsessid=803db60816b9f8203fb8feca01c130b6; path=/";     "transfer-encoding" = identity;     vary = "accept-encoding,user-agent";     "x-powered-by" = "php/5.5.17"; 

this without afnetworking:

nsstring *post = @"offset=1&csrf-token=63b164ea557b4aba694f81520c71972fa43a9772"; nsdata *postdata = [post datausingencoding:nsutf8stringencoding allowlossyconversion:yes];  nsstring *postlength = [nsstring stringwithformat:@"%d", [postdata length]];  nsmutableurlrequest *request = [[nsmutableurlrequest alloc] init]; [request seturl:[nsurl urlwithstring:@"http://simple.com/"]]; [request sethttpmethod:@"post"]; [request setvalue:postlength forhttpheaderfield:@"content-length"]; [request setvalue:@"application/x-www-form-urlencoded; charset=utf-8" forhttpheaderfield:@"content-type"]; [request sethttpbody:postdata];   nsurlconnection *connection = [[nsurlconnection alloc] initwithrequest:request delegate:self];  nshttpurlresponse *response = nil; nserror *error = nil; nsdata *respdata = [nsurlconnection sendsynchronousrequest:request returningresponse:&response error:&error]; nslog(@"~~~~~ status code: %d", [response statuscode]);  

and again error: 400

please solve problem

i solved problem.

the fact server keeps session specific csrf token. mistake used same token, in browser, , mobile device. therefore, server , did not give details getting wrong post request.

my solution: first server csrf token, , further post queries use resulting token. in response post request status 200 , data needed.

true afnetworking not in problem, had use standardnsurlconnection (i put code in question). maybe in future come in handy!

thanks all! luck all!
