AFNETWORKING 3.0 Post Request Fail - objective-c

Question

I sent a request to server using AFNETWORKING 3.0 with the following parameters:
NSString *uniqueIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:_texLoginUname.text forKey:#"ent_email"];
[parameters setObject:_textLoginPassword.text forKey:#"ent_password"];
[parameters setObject:uniqueIdentifier forKey:#"ent_device_id"];
[parameters setObject:#"2" forKey:#"eat_device_type"];
[parameters setObject:#"22" forKey:#"ent_device_token"];
Here is my code:
NSString *URL = #"http://optime.in/apps/food_truck/user_api/login";
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[manager POST:URL parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject)
{
NSLog(#"success!");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"error: %#", error);
NSData *errorData = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData: errorData options:kNilOptions error:nil];
NSLog(#"val = %#",serializedData);
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error while sending POST"
message:#"Sorry, try again."
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
}];
And i got this error:
NSLocalizedDescription=Request failed: not found (404),
NSUnderlyingError=0x7be19ef0 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html"
UserInfo={com.alamofire.serialization.response.error.response=http://optime.in/apps/food_truck/user_api/login } { status code: 404, headers {
Connection = "Keep-Alive";
"Content-Length" = 302;
"Content-Type" = "text/html; charset=iso-8859-1";
Date = "Tue, 20 Sep 2016 08:12:20 GMT";
"Keep-Alive" = "timeout=5, max=100";
Server = "Apache/2.4.7 (Ubuntu)";
} }, NSErrorFailingURLKey=#"mylink"
, NSLocalizedDescription=Request failed: unacceptable content-type: text/html,
Kindly help me to solve this error.

Answer 1

you should use below Method because AFJSONRequestSerializer is not working is AFNetworking 3.0
This method can work because I use this and only method
NSString *uniqueIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:_texLoginUname.text forKey:#"ent_email"];
[parameters setObject:_textLoginPassword.text forKey:#"ent_password"];
[parameters setObject:uniqueIdentifier forKey:#"ent_device_id"];
[parameters setObject:#"2" forKey:#"eat_device_type"];
[parameters setObject:#"22" forKey:#"ent_device_token"];
NSString *URL = #"http://optime.in/apps/food_truck/user_api/login";
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:url]];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript",#"text/html", nil];
[manager POST:URL parameters:_parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(#"success!");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"error: %#", error);
}];
Hope this thing works
