Question

我正在尝试使用ASIHTTPRequest到cache响应数据，我已阅读文档并尝试了许多解决方案，但没有运气：（

这是我的代码：

_request = [[ASIFormDataRequest alloc]initWithURL:[NSURL URLWithString:NSLocalizedString(@"kBaseUrl", nil)]];
_request.delegate = self;
[_request setDownloadCache:[ASIDownloadCache sharedCache]];
[[ASIDownloadCache sharedCache] setShouldRespectCacheControlHeaders:NO];
[_request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy];//ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy
[_request setSecondsToCache:60*60*24*2]; // Cache for 2 days
[_request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[_request setDefaultResponseEncoding:NSUTF8StringEncoding];
[_request setDidFinishSelector:@selector(doneLoadingBody:)];
[_request setDidFailSelector:@selector(failedLoadingBody:)];
[_request setRequestMethod:@"POST"];
[_request setShouldContinueWhenAppEntersBackground:YES];
[_request setPostValue:@"someValue" forKey:@"name"];
[_request setPostValue:@"someValue" forKey:@"key"];
[_request setPostValue:@"someValue" forKey:@"key"];
[_request startAsynchronous];

if ([_request didUseCachedResponse] == NO) {

    NSLog(@"Did not Cache Body");

}

您正在使用ASIFormDataRequest，它基本上是一个POST操作。

由于POST不是幂等操作，我怀疑它是可缓存的。

也许您应该开始使用GET请求测试缓存机制。

一些参考：Is it possible to cache POST methods in HTTP?
