ios HTTP load failed (error code: 303 下载失败解决方法

出现这个错误的的原因一般是,https所致,

方法一:可以通过更改工程plist文件,对要下载文件的URL的host做设置,如下:



方法二:在相应的vc,我是vc里边调用下载方法抱着个错误,可以实现如下代理方法:

遵守代理,设置代理:

@interface DownLoadFileManager : NSObject<NSURLSessionDataDelegate>
-(NSURLSession *)session{
    if (!_session) {
        _session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:[[NSOperationQueue alloc] init] ];
    }
    return _session;
}


实现方法:

-(void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler{
    completionHandler(NSURLSessionAuthChallengeUseCredential,[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]);
}
