Question

这是我用来上传PDF的curl命令，它完美运行：

curl -u USERNAME:PASSWORD -T MyPDF.pdf —url https://mywebserver.com

我正在使用NSURLSession并使用委托上传任务，但我的PDF永远不会上传。

这是我的代码：

- (IBAction)upload:(id)sender {
    NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:nil];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:@"https://mywebserver.com/"]];
    [request setHTTPMethod:@"POST"];

    NSString* pdfPath = [[NSBundle mainBundle] pathForResource:@"bill" ofType:@"pdf"];
    NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request fromFile:[NSURL fileURLWithPath:pdfPath]];

    [uploadTask resume];
}

- (void)URLSessionDidFinishEventsForBackgroundURLSession:(NSURLSession *)session {

}

- (void)URLSession:(NSURLSession *)session task:(nonnull NSURLSessionTask *)task didCompleteWithError:(nullable NSError *)error {
    if (error) {
        NSLog(@"Error = %@", error);
    }
}

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(nonnull NSURLAuthenticationChallenge *)challenge completionHandler:(nonnull void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler {
    completionHandler(NSURLSessionAuthChallengePerformDefaultHandling, [NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession]);
}

- (void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask
didReceiveResponse:(NSURLResponse *)response
 completionHandler:(void (^)(NSURLSessionResponseDisposition disposition))completionHandler {
    completionHandler(NSURLSessionResponseAllow);
}

- (void)URLSession:(NSURLSession *)session dataTask:(nonnull NSURLSessionDataTask *)dataTask didReceiveData:(nonnull NSData *)data {
    if (data) {
        NSLog(@"%@",[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
    }

}

- (void)URLSession:(NSURLSession *)session didBecomeInvalidWithError:(nullable NSError *)error {
    if (error) {
        NSLog(@"Error = %@", error);
    }
}

Answer 1

如果您尝试将完成块与 NSURLSessionAuthChallengeUseCredential

一起使用会发生什么

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(nonnull NSURLAuthenticationChallenge *)challenge completionHandler:(nonnull void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler {
    completionHandler(NSURLSessionAuthChallengeUseCredential, 
    [NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession]);
}

一般情况下，请确保您的上传首先适用于不受保护的服务器。而不是用凭证进行测试。

Answer 2

NSURLSessionAuthChallengeUseCredential具有相同的行为。

NSURLSession执行上传任务为＆＃39; curl＆＃39;
