我有一个简单的 NSURLRequest:

[NSURLConnection sendAsynchronousRequest:myRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    // do stuff with response if status is 200
}];

如何获取状态码以确保请求正常？

最佳答案

从响应中转换一个 NSHTTPURLResponse 的实例并使用它的 statusCode 方法。

[NSURLConnection sendAsynchronousRequest:myRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
    NSLog(@"response status code: %ld", (long)[httpResponse statusCode]);
    // do stuff
}];
