Question

所以我目前正在使用Facebook登录我的iOS应用程序，服务器管理员最近通过要求Facebook访问令牌以及通过https进行所有连接来添加安全身份验证。这是我尝试过运行的代码，但无论我做什么，我的服务器响应错误都是500（内部服务器错误）。有什么想法吗？

NSMutableURLRequest *request = [NSMutableURLRequest
                                requestWithURL:[NSURL URLWithString:@"https://XXXXXXXXXXXXXXXX/users.json"]];

NSDictionary *requestData = [[NSDictionary alloc] initWithObjectsAndKeys:
                     userID, @"facebook_id",
                     FBAccessToken, @"fb_token",
                     userName, @"name",
                     nil];
NSError *error;
NSData *postData = [NSJSONSerialization dataWithJSONObject:requestData options:0 error:&error];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

Answer 1

以下是您记录响应正文的方式。

@property (strong, nonatomic) NSMutableData *responseData;

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    self.responseData = [NSMutableData data];
    …
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [self.responseData appendData:data];
    …
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"response data - %@", [[NSString alloc] initWithData:self.responseData encoding:NSUTF8StringEncoding]);
    …
}

Answer 2

您还需要符合NSURLConnectionDelagate协议。
