AFNetwoking POST call returns 500 internal server error but server got request parameter

I'm trying to upload my payment success message to my server. Below are my code

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
[manager.requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@",myTokenString] forHTTPHeaderField: @"Authorization"];


AFHTTPRequestOperation *operation = [manager POST:@"MYAPI" parameters:paramsDict success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"%@",responseObject);


} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"%@",error.localizedDescription);

}];
[operation start];

But I'm getting error code 500 (internal server error). But my server has all the information and API call is success. Can anyone please help me understand why it's entering the error block?

Add the below coding to AFURLResponseSerialization.m file and remove the existing code.

@implementation AFJSONResponseSerializer

self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/xml",@"text/html", nil];

return self;

Try to see what the detail accept/content type is for android. Do you know if they are using retrofit? Most likely it will have to do with your request or response serializer not matching what server is expecting.

In new AFNetworking version, you don't need a initialize for AFHTTPRequestOperation class to handle request so you just adjust your code as following:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@",myTokenString] forHTTPHeaderField: @"Authorization"];

[manager POST:@"MYAPI" parameters:paramsDict success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"%@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%@",error.localizedDescription); 
}];

I had been encountering the same issue with AFNetworking POST as well as sometimes on GET calls but... Sometimes i would get a 500 internal server error although the server received request parameters!! Finally after some research with my web services backend developers, i came to know that its caused due to a DLL misconfiguration on the server side, particularly the System.reflection DLL file. Deleting the file from the server side (if it exists) removes the issue, otherwise copy pasting it back from the Bin (if it doesn't exist already) removes the issue. This is pretty baffling but apparently it fixes it!!

AND YES. IT HAS NOTHING TO DO WITH AFNETWORKING! The answer assumes Microsoft azure server

Try with formData 

[manager POST:@"API" parameters:paramsDict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

} progress:^(NSProgress * _Nonnull uploadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

}];

it's AFNetworking 3.0 Method, but you can used same (formData) in AFNetworking 2.x

Encode your url.

NSString *unescaped = @"http://www";
NSString *escapedString = [unescaped stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLHostAllowedCharacterSet]];

By default requestSerializer is set to an instance of AFHTTPRequestSerializer, which means that Content-Type of your request will be application/x-www-form-urlencoded.

But if your server requires application/json content type for that api, then you must set to an instance of AFJSONResponseSerializer
E.G. 

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
 manager.requestSerializer = [AFJSONRequestSerializer serializer];
