AFNetworking 检查响应

Question

如何检查是否返回响应：

HTTP/1.1 302 Moved Temporarily

Server: nginx/1.5.6

Content-Type: text/html

Transfer-Encoding: chunked

请求代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    AFHTTPRequestSerializer * requestSerializer = [AFHTTPRequestSerializer serializer];
    [requestSerializer setValue:ua forHTTPHeaderField:@"User-Agent"];
    manager.requestSerializer = requestSerializer;
    AFHTTPResponseSerializer * responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.responseSerializer = responseSerializer;
    NSDictionary *parameters = @{@"login": myLogin, @"pass": myPassword};
    [manager POST:urlLogin parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if ([operation.responseString rangeOfString:@""].location == NSNotFound) {
            NSLog(@"Login or password false");
        } else {

如果响应html我是这样做的if ([operation.responseString rangeOfString: @ "Then I put the titel"]. Location == NSNotFound)，但不知道在这种情况下该怎么做

Answer 1

The Foundation URL 加载系统会自动将您的请求重定向到 Location header.

中指定的路径

如果您需要拦截重定向，通常是为了处理身份验证问题，您可以在 operation object 上设置身份验证质询块（如果需要，还可以设置重定向响应块）。

Here's an AFNetworking GitHub issue 其中讨论了这个问题。如果您需要，它有一些示例代码。
