Mollie v2 .NET 库创建和检查支付请求的状态

Question

我想将我的 Mollie .NET 支付客户端（参见 https://github.com/Viincenttt/MollieApi）从 v1 升级到 v2。

我已经安装了库，但无法创建付款请求或检查其状态，因为我找不到示例中所述的 Amount 方法和 Currency 类型代码：

IPaymentClient paymentClient = new PaymentClient("{yourApiKey}");
PaymentRequest paymentRequest = new PaymentRequest() {
    Amount = new Amount(Currency.EUR, "100.00"),
    Description = "Test payment of the example project",
    RedirectUrl = "http://google.com"
};

Github 存储库不是很活跃，开发人员没有响应那里的问题，所以希望这里有人能够帮助我。

我已经检查了所有类以及来自 Github 的示例项目。我尝试使用 "F12 / Go to definition" 在示例项目中找到相关 methods/types 的定义，但是失败了。所以我现在卡住了。

这是我的 Intellisense 显示的内容：

我做错了什么？

我进一步导入了正确的库并检查了@Nkosi 推荐的 migration docs。

我现在有下面的代码，但出现错误：

BC37058 'Await' can only be used within an Async method. Consider marking this method with the 'Async' modifier and changing its return type to 'Task'.

在

Dim paymentResponse As PaymentResponse = Await paymentClient.CreatePaymentAsync(paymentRequest)

C#示例代码是

PaymentResponse paymentResponse = await paymentClient.CreatePaymentAsync(paymentRequest);

但我不知道如何转换为 VB.net，在线代码转换器也没有提供任何解决方案。

Dim paymentClient As Mollie.Api.Client.PaymentClient

If ConfigurationManager.AppSettings("IsDevelopment") = "true" Then
    paymentClient = New Client.PaymentClient(ConfigurationManager.AppSettings(String.Format("mollie_api_testkey_{0}", _lang)))
Else
    paymentClient = New Client.PaymentClient(ConfigurationManager.AppSettings(String.Format("mollie_api_livekey_{0}", _lang)))
End If

Select Case hfPaymentMethod.Value
    Case "ideal"
        Dim paymentRequest As New Mollie.Api.Models.Payment.Request.IdealPaymentRequest
        paymentRequest.Amount = New Amount(Currency.EUR, "100.00") ' decimalAmount.ToString
        paymentRequest.Description = "Subscription. id:" + _vendorId.ToString + " t:" + _objtype.ToString
        paymentRequest.RedirectUrl = ConfigurationManager.AppSettings(String.Format("WebAddress_{0}", _lang)) + "paymentvalidate?oid=" + newOrderId.ToString +
            "&transactiontype=subscription&id=" + _vendorId.ToString + "&t=" + _objtype.ToString + "&lvl=" + ddlSubscription.SelectedValue.ToString

        Dim paymentResponse As PaymentResponse = Await paymentClient.CreatePaymentAsync(paymentRequest)

        orderTA.UpdateOrderTransactionId(paymentResponse.Id, newOrderId)

        Response.Redirect(paymentResponse.Links.Checkout.ToString)

    Case "paypal"
        Dim paymentRequest As New Mollie.Api.Models.Payment.Request.PayPalPaymentRequest
    Case "creditcard"
        Dim paymentRequest As New Mollie.Api.Models.Payment.Request.CreditCardPaymentRequest
End Select

好的，更进一步，现在正在触发调用。但是，我现在收到此错误：

The provided token isn't an oauth token.

在线

Dim paymentStatus As PaymentResponse = Await paymentClient.GetPaymentAsync(transactionId, True)`

请注意更新 2 中我的代码块（在我的 upgrade.aspx 页面上）我存储了事务 ID，例如tr_VneHN4axS9 在我的订单 table 此处：

orderTA.UpdateOrderTransactionId(paymentResponse.Id, newOrderId)

newOrderId 也附加在付款请求的重定向 URL 中，因此我可以在 paymentvalidate 页面上再次检索正确的订单：

paymentRequest.RedirectUrl = ConfigurationManager.AppSettings(String.Format("WebAddress_{0}", _lang)) + "paymentvalidate?oid=" + newOrderId.ToString +
                "&transactiontype=subscription&id=" + _vendorId.ToString + "&t=" + _objtype.ToString + "&lvl=" + ddlSubscription.SelectedValue.ToString`

在我的 paymentvalidate.aspx 页面上，我从 URL 获取 orderid，然后使用它来检索 transactionId：

Dim orderId As Integer = ReturnQueryString(Request.Params("oid"), 0)            
Dim transactionId As String = orderTA.GetDataOrderById(orderId)(0).transactionId

但是当我尝试像这样检索该交易的状态时：

Dim paymentStatus As PaymentResponse = Await paymentClient.GetPaymentAsync(transactionId, True)`

我收到错误

The provided token isn't an oauth token.

为什么会抛出这个错误？

问题列表中有关于该错误的内容：https://github.com/Viincenttt/MollieApi/issues/61

因此，如果：(!string.IsNullOrWhiteSpace(paymentRequest.ProfileId) || paymentRequest.Testmode.HasValue || paymentRequest.ApplicationFee != null) 它将运行 this.ValidateApiKeyIsOauthAccesstoken();。
