ios - AFNetworking (200-299) 中的预期状态代码，得到 403

Question

尝试将我的代码从 ASIHttpRequest 迁移到 AFNetworking。似乎有人问过类似的问题，但无法找到我的问题的解决方案。

我的代码在 ASIHttpRquest 下运行良好。

我向我的服务器发送一个简单的 post 请求并监听 http 响应。如果 http response 是 200 一切正常，但如果我发送另一个状态代码 >400 AFNetworking block 失败。

服务器端响应:

$rc = $stmt->fetch();
    if ( !$rc ) {
    //  echo "no such record\n";
      $isrecordExist=0; //false does not exists
      sendResponse(403, 'Login Failed');
      return false;
    }
    else {
     // echo 'result: ', $result, "\n";
       $sendarray = array(
            "user_id" => $result,
        );
        sendResponse(200, json_encode($sendarray));
    }

IOS部分:

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:
                            [NSURL URLWithString:server]];
    client.allowsInvalidSSLCertificate=YES;

    [client postPath:loginForSavingCredientials parameters:params success:^(AFHTTPRequestOperation *operation, id response) {
    if (operation.response.statusCode == 500) {}
     else if (operation.response.statusCode == 403) {}
     else if (operation.response.statusCode == 200) {//able to get results here            NSError* error;
        NSString *responseString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
        NSDictionary* json =     [NSJSONSerialization JSONObjectWithData: [responseString dataUsingEncoding:NSUTF8StringEncoding]
                                                                 options: NSJSONReadingMutableContainers
                                                                   error: &error];}
 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"failure %@", [error localizedDescription]);
    }];

NS日志:

 failure Expected status code in (200-299), got 403

我该如何解决这个问题？

Answer 1

当 AFNetworking 获得 2xx(成功)状态代码时，它会调用成功 block 。

当它收到 4xx(客户端错误)或 5xx(服务器错误)状态代码时，它会调用失败 block ，因为出了点问题。

因此，您需要做的就是将对 500 或 403 状态代码的检查移至失败 block 。

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:server]];
client.allowsInvalidSSLCertificate=YES;

[client postPath:loginForSavingCredientials parameters:params success:^(AFHTTPRequestOperation *operation, id response) {
    if (operation.response.statusCode == 200) {//able to get results here            NSError* error;
        NSString *responseString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
        NSDictionary* json = [NSJSONSerialization JSONObjectWithData: [responseString dataUsingEncoding:NSUTF8StringEncoding]
                                                             options: NSJSONReadingMutableContainers
                                                               error: &error];
    }
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"failure %@", [error localizedDescription]);
    if (operation.response.statusCode == 500) {}
    else if (operation.response.statusCode == 403) {}
}];
