Question

网址是＆＃34; http://pics2.xiaoma.com/xiaoma/bbs/app/tpo/ky/TPO27-3.mp3＆＃34;。此URL是MP3文件，我无法正常播放。这是我正在使用的代码。需要指导我在这里做错了什么。

+ (ASIHTTPRequest *)requestAudioDataWithURLString:(NSString *)urlString
                                   completion:(CompeletionHandle)block {

//3.创建请求
ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:urlString]];
[request setTimeOutSeconds:20];
[request setRequestMethod:@"GET"];
[request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[request setCachePolicy:ASIAskServerIfModifiedWhenStaleCachePolicy | ASIFallbackToCacheIfLoadFailsCachePolicy];
[request setDownloadCache:[ASIDownloadCache sharedCache]];

//4.开始异步请求
[request startAsynchronous];

//5.请求成功
__weak ASIFormDataRequest *weakRequest = request;
[request setCompletionBlock:^{
    //
    ASIFormDataRequest *strongRequest = weakRequest;
    NSData *data = strongRequest.responseData;
    if (weakRequest.didUseCachedResponse) {
        MYLog(@"使用缓存数据");
    }
    else
    {
        MYLog(@"请求网络数据");
    }
    block(data);
}];

//6.请求失败
[request setFailedBlock:^{
    ASIFormDataRequest *strongRequest = weakRequest;
    block(strongRequest.error);
    MYLog(@"%@",strongRequest.error);
}];

return request;  }

日志几乎是＆＃34; 0000000 00000000 ...＆＃34;。

正确的响应可以正常播放的节目是

{
"Accept-Ranges" = bytes;
Age = 2;
"Cache-Control" = "max-age=633841";
Connection = close;
"Content-Length" = 1659957;
"Content-Type" = "audio/mpeg";
Date = "Mon, 30 Jun 2014 10:05:29 GMT";
Expires = "Mon, 07 Jul 2014 18:09:30 GMT";
"Last-Modified" = "Thu, 05 Jun 2014 03:05:47 GMT";
Server = "marco/0.1";
"X-Cache" = "MISS|MISS from cache_img_94, MISS from ctn-zj-ngb-107, MISS from usn-us-sms-058";
"X-Source" = "U/200";}

无法播放的错误responseHeaders是

{
"Accept-Ranges" = bytes;
Age = 0;
"Cache-Control" = "max-age=622695";
Connection = close;
"Content-Length" = 3028113;

Expires = "Thu, 03 Jul 2014 19:39:02 GMT";
"Last-Modified" = "Thu, 05 Jun 2014 03:06:23 GMT";
Server = "marco/0.1";
"X-Cache" = "MISS from usn-us-sms-058";
"X-Source" = "U/304";}

{

根本不确定这是否是你的问题，但MP3花了很长时间才开始下载（即使它只有2.1mb。）

[request setTimeOutSeconds:20];

下载开始之前是否有可能超时？
