IOS 7如何打印url响应数据

Question

我正在尝试调用网络服务。我试过了

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://192.168.75.1:8082/projectname/public/tests"]];
    NSURLSessionConfiguration *configuration = [ NSURLSessionConfiguration ephemeralSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration];
    NSURLSessionDownloadTask *task = [session downloadTaskWithRequest:request completionHandler:^(NSURL *localFile, NSURLResponse *response, NSError *error) {
        if(!error){
            NSLog(@"no error");

        }else{
            NSLog(@"error");
        }
    }];
    [task resume];
}

如您所见，有两个 nslog 语句。我得到了 no error 一个。

当我从我的 safari 调用该 Web 服务时，我在浏览器中打印了一个简单的 index 字符串，请问我如何在我的 xcode 中看到该字符串？

谢谢

你可以实现委托(delegate)方法

- (void)URLSession:(NSURLSession *)session downloadTask:(NSURLSessionDownloadTask *)downloadTask didFinishDownloadingToURL:(NSURL *)location;

试试这个

NSHTTPURLResponse *response = nil;
NSError *error = nil;

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL      URLWithString:YOUR URL]];
NSData *respData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"~~~~~ Status code: %d", [response statusCode]);
//Print your recived data here..
NSString *str = [[NSString alloc] initWithData:respData encoding:NSUTF8StringEncoding];
NSLog(@"str: %@", str);
