Question

我目前正在尝试使用ASIHTTPRequest包装器解压缩一些数据..但不确定需要做什么。我已经阅读了文档，但它给了很多细节..

这是我到目前为止所做的： //的.h

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

// ...

//。米

//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];
}

响应看起来像这样

所以我很确定布尔值没有被设置为它给我一个Null值。你们能看到我做错了吗？如果设置了bool，则仅将数据传递给requestFinished？或者这里有更深层次的问题吗？

Answer 1

ASIHTTPRequest仅知道下载是否被压缩，如果它由服务器提供服务，该服务器将内容编码HTTP响应头设置为“gzip”。

你的测试/网络服务器是这样做的吗？

此外，在您的代码中，将NSLog行更改为：

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

ASIHTTPRequest gzip解压缩
