ASIHTTPRequest gzip decompression

Question

我目前正试图解压缩一些数据，我已经进入ASIHTTPRequest包装器。但不确定需要做什么。我已经阅读了文档，但是它没有给出很多细节。

这是我目前所拥有的://. h

//Compression stuff
BOOL dataWasCompressed;
NSData *compressedResponse;
NSData *uncompressedData;
NSString *response;

//……

//m

//Compression Test
- (IBAction)sendHttpsRequest
{
    //Start HUD
        [SVProgressHUD showWithMaskType:SVProgressHUDMaskTypeBlack];
        [SVProgressHUD setStatus:@"loading..."];
        NSURL *url = [NSURL URLWithString:@"http://127.0.0.1:8888/testConnection/ClientDataSet.xml.compressed"];
        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
        // YES is the default, you can turn off gzip compression by setting this to NO
        [request setAllowCompressedResponse:YES];
        [request startSynchronous];
        dataWasCompressed = [request isResponseCompressed]; // Was the response gzip compressed?
        compressedResponse = [request rawResponseData]; // Compressed data
        uncompressedData = [request responseData]; // Uncompressed data
        response = [request responseString]; // Uncompressed data as a string

    NSLog(@"compressed? %@", dataWasCompressed);
    NSLog(@"compressed Response = %@", compressedResponse);
    NSLog(@"uncompressed Data = %@", uncompressedData);
    NSLog(@"response = %@", response);
}
- (void)requestFinished:(ASIHTTPRequest *)request
{   
    self.hudCheck = YES;
    responseString = [request responseString]; //Pass requested text from server over to NSString 
    NSLog(@"Response String = %@", responseString);
    //removies the SVProgressHUD
    [NSTimer scheduledTimerWithTimeInterval:0.25 target:self selector:@selector(stopAnimating) userInfo:nil repeats:NO];
}

反应是这样的

所以我很确定布尔值没有被设置为它给我一个空值。你们能看出我做错了什么吗?如果设置bool，数据是否只传递给requestFinished ?还是有更深层次的问题?

Answer 1

ASIHTTPRequest只有在服务器将内容编码的HTTP响应头设置为"gzip"时才知道下载是否被压缩。

你的测试/web服务器正在这样做吗?

同样，在代码中，将NSLog行更改为:

NSLog(@"compressed? %@", dataWasCompressed ? @"YES" : @"NO" );
