出现问题SDWebImage版本号 2.7.4
1.1 图片加载请求失败 NSURLErrorDomain - Code = 404
{
但是用sdwebimage显示不了。 后来我换了另一个图片url是可以显示的。
最后，我直接下载这张图片，发现报错了：Error Domain=NSURLErrorDomain Code=404
“The operation couldn’t be completed. (NSURLErrorDomain error 404.)”
}
1.2 解决方法
{
///Mark： 设置 Downloader
downloader.userInfo = userInfo;
downloader.lowPriority = lowPriority;
[downloader performSelectorOnMainThread:@selector(start) withObject:nil waitUntilDone:YES];
NSLog(@"下载图片地址:%@",downloader.url);
///MARK: 请求响应
- NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:15];
+ NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:15];
self.connection = SDWIReturnAutoreleased([[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO]);
+#ifdef SD_WEBP
+ [request setValue:@"image/webp,image/*;q=0.8" forHTTPHeaderField:@"Accept"];
+#else
+ [request setValue:@"image/*;q=0.8" forHTTPHeaderField:@"Accept"];
}
1.3 解释说明
{
406 Not Acceptable - The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request
}
