如何以.Net C#Windows窗体将文件上载到Firebase存储？ [英] How to Upload File to Firebase Storage in .Net C# Windows Form?

问题描述

我尝试了以下函数将图像上载到Firebase存储

 private async void UploadFiles()
    {

        var stream = File.Open(@"D:\Capture.png", FileMode.Open);
        var auth = new FirebaseAuthProvider(new FirebaseConfig(ApiKey));
        var a = await auth.SignInWithEmailAndPasswordAsync(AuthEmail, AuthPassword);

        var cancellation = new CancellationTokenSource();
        var task = new FirebaseStorage(
            Bucket,
            new FirebaseStorageOptions
            {
                AuthTokenAsyncFactory = () => Task.FromResult(a.FirebaseToken),
                ThrowOnCancel = true // when you cancel the upload, exception is thrown. By default no exception is thrown
            })
            .Child("receipts")
           // .Child("test")
            .Child("Capture.png")
            .PutAsync(stream, cancellation.Token);
        task.Progress.ProgressChanged += (s, e) => textBox1 .Text =($"Progress: {e.Percentage} %");

        // cancel the upload
        // cancellation.Cancel();

        try
        {
            // error during upload will be thrown when you await the task
          textBox1 .Text =("Download link:
" + await task);
        }
        catch (Exception ex)
        {
            MessageBox .Show( ex.Message);
        }
    }

获取此错误：

处理请求时出现异常。 URL：https://firebasestorage.googleapis.com/v0/b/gs://testingsupport-44f0b.appspot.com//o?name=receipts%2FCapture.png 响应：{ "错误"：{ "code"：400， "message"："无效的HTTP方法/URL对。" } )

推荐答案

您必须编辑Bucket变量。它应该仅为xxxxx.appspot.com

，而不是使用gs://xxxxx.appspot.com/
