使用AFNetworking添加要求的参数

Question

我最近跟着CodeSchool课程学习iOS,他们建议使用AFNetworking与服务器进行交互.

我试图从我的服务器获取一个JSON,但我需要将一些参数传递给网址.我不希望将这些参数添加到URL,因为它们包含用户密码.

对于简单的URL请求,我有以下代码:

NSURL *url = [[NSURL alloc] initWithString:@"http://myserver.com/usersignin"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];

AFJSONRequestOperation *operation = [AFJSONRequestOperation
       JSONRequestOperationWithRequest:request
               success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
                        NSLog(@"%@",JSON);
               } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                        NSLog(@"NSError: %@",error.localizedDescription);             
               }];

[operation start];

我已经检查了NSURLRequest的文档,但从那里得不到任何有用的东西.

如何将用户名和密码传递给此请求以在服务器中读取？

你可以使用AFHTTPClient:

NSURL *url = [[NSURL alloc] initWithString:@"http://myserver.com/"];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:url];

NSURLRequest *request = [client requestWithMethod:@"POST" path:@"usersignin" parameters:@{"key":@"value"}];

AFJSONRequestOperation *operation = [AFJSONRequestOperation
   JSONRequestOperationWithRequest:request
           success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
                    NSLog(@"%@",JSON);
           } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                    NSLog(@"NSError: %@",error.localizedDescription);             
           }];

[operation start];

理想情况下,您需要子类化AFHTTPClient并使用其postPath:parameters:success:failure:方法,而不是手动创建操作并启动它.
