objective-c - AF网络检查响应

Question

如何检查响应是否返回:

HTTP/1.1 302 Moved Temporarily

Server: nginx/1.5.6

Content-Type: text/html

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我这样做if([operation.responseString rangeOfString:@"Then I put the title"].Location == NSNotFound)，但不知道如何在这种情况下做

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 操作 对象上设置身份验证质询 block (如果需要，还可以设置重定向响应 block )。

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