Question

我尝试了以下功能将图像上传到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:\n" + await task);
        }
        catch (Exception ex)
        {
            MessageBox .Show( ex.Message);
        }
    }

让我知道这个错误：

处理请求时发生异常。网址：https://firebasestorage.googleapis.com/v0/b/gs://testingsupport-44f0b.appspot.com//o?name=receipts%2FCapture.png 回应：{ “错误”：{ “代码”：400， “ message”：“无效的HTTP方法/ URL对。” } }

Answer 1

您必须编辑Bucket变量。不应使用gs://xxxxx.appspot.com/，而应仅使用xxxxx.appspot.com

Answer 2

这里有一个代码，可以帮助您在实时数据库中加载base64格式的图像。我会给你链接，很快再见。
