                                                                  description:

NSLog(@"Error from server: %@, status code = %ld, error type = %lu", requestError.errorDescription, (long)requestError.statusCode, (unsigned long)requestError.type);
onFailure(requestError);

}];

请注意添加
[manager.requestSerializer setValue:@"application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];

这是完整的代码：

NSString *url = [NSString stringWithFormat:@"%@%@",APIBASE,APIUSERENDPOINT];

NSDictionary* parametersDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
username, @"username",
password, @"password",
nil
];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[manager.requestSerializer setValue:@"application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];

[manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
