【问题描述】：

我有一个通过我的应用程序中的一个 api 显示的视频。我想上传并保存在我的设备上，我正在使用此代码：

- (IBAction)saveMovie:(id)sender {

    NSString *path = @"http://development.s3.amazonaws.com/uploads/f1a97ec0-e47f-470e-96a6-de98d2235dd0/Biceps.mp4";

    if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path)){
        UISaveVideoAtPathToSavedPhotosAlbum(path, nil, nil, nil);
        [self alert];
    } else {
        NSLog(@"incompatible video");
    }
}

链接“路径”是上传文件的自己的链接，但也有查看链接。

当我调用接收答案的方法时

Video http://development.s3.amazonaws.com/uploads/f1a97ec0-e47f-470e-96a6-de98d2235dd0/Biceps.mp4 cannot be saved to the saved photos album: Error Domain=NSURLErrorDomain Code=-1100 "The requested URL was not found on this server." UserInfo=0x1660f300 {NSErrorFailingURLStringKey=file:///http:/xerofit-development.s3.amazonaws.com/uploads/f1a97ec0-e47f-470e-96a6-de98d2235dd0/Biceps.mp4, NSErrorFailingURLKey=file:///http:/xerofit-development.s3.amazonaws.com/uploads/f1a97ec0-e47f-470e-96a6-de98d2235dd0/Biceps.mp4, NSLocalizedDescription=The requested URL was not found on this server., NSUnderlyingError=0x16542030 "The operation couldn’t be completed.

怎么了？

【解决方案1】：

我尝试从 NSTemporaryDirectory 执行此操作，并且成功了。看来，如果有人接受这种方式。

就我而言，我放了这个网址

http://qa-elb-765904057.us-west-2.elb.amazonaws.com/plugin/execute?pluginName=xxxx&pluginMethod=xxxx&clientId=b0007920-88b4-11e5-a62a-fxxxxx&token=xxx94d60-91xx-11e5-a62a-f362d1d2xxx0&file_key=Mbxxx5v6RxxxQOR.mp4

错误是这样的

Video /plugin/execute cannot be saved to the saved photos album: Error Domain=NSURLErrorDomain Code=-1100 "The requested URL was not found on this server." UserInfo=0x176644e0 {NSErrorFailingURLStringKey=file:///plugin/execute, NSErrorFailingURLKey=file:///plugin/execute, NSLocalizedDescription=The requested URL was not found on this server., NSUnderlyingError=0x17661850 "The operation couldn’t be completed. No such file or directory", NSURL=file:///plugin/execute}

似乎发送的整个 url 只检测到这个

/plugin/execute
