ios - AFNetworking 2.0 Send Post Request with URL Parameters

Question

How do I send a POST request with AFNetworking 2.0 with all the parameters in the URL like such:

http://www.myserver.com?api_key=something&lat=2.4&radius=100

Right now I have:

NSString* query = @"http://example.com?name=param&date=param";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{};
[manager POST:query parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

But it's not working, I get this error back:

Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: bad request (400)

The previous best answer was to get the backend to change and accepts parameters in the body. Thats the preferred method but sometimes some of us are stuck using backends that can't change so I offer this solution....

In the class AFURLRequestSerialization there is a property called HTTPMethodsEncodingParametersInURI and that is an NSSet that contains the http methods that are allowed to use params in the uri GET, HEAD, and DELETE by default.

You could override that and include POST as well.

in AFURLRequestSerialization.m lines 462 has an if statement that checks self.HTTPMethodsEncodingParametersInURI property contains POST. if it doesn't (as it doesn't by default), it will put the parameters in the body.

You can comment out that id statement for a quick test.

To get it to work I recommend overwriting the HTTPMethodsEncodingParametersInURI property.

when setting up your AFHTTPSessionManager it should look like this...

  AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:self.httpBaseUrl]];
   manager.requestSerializer = [AFHTTPRequestSerializer serializer];
   manager.requestSerializer.HTTPMethodsEncodingParametersInURI = [NSSet setWithArray:@[@"POST", @"GET", @"HEAD", whatever other http methods you need here....]];

this should allow for sending a parameters in the uri of a POST. worked for me, hope it helps someone else
