天蓝色“实时商店”上的 PayPal 身份验证问题

Question

我在尝试使用 paypal API 时收到以下错误

HttpStatusCode: Unauthorized; AUTHENTICATION_FAILURE; Authentication failed due to invalid authentication credentials or a missing Authorization header.

但问题仅在于我将代码发布到 Azure Api 时。如果我在 Visual Studio 上运行 Live Store，它就可以工作。

    public async Task<bool> InvoicingCreate(Models.ShopTransaction t)
    {
        sentJson = null;
        if (_accessToken == null) await GetAccessTokenAsync();

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "v2/invoicing/invoices");
        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", _accessToken.access_token);

        bool addNotes;
        if (t.Product.TotalPrice == 0.0) addNotes = false;
        else if (t.PaymentMethod == null) addNotes = true;
        else if (t.PaymentMethod == "paypal" || t.PaymentMethod == "credit_card") addNotes = false;
        else addNotes = true;

        string billingEmail;
        if (t.Product.IndividualCouponId.HasValue)
        {
            billingEmail = _configuration["Shop:CouponInvoiceEmail"];
        }
        else
        {
            billingEmail = t.BillingAddress.Email;
        }
        var inv = new Root
        {
            detail = new Detail
            {

        .......details the items. ...
            },


        .......Fill the items. ...


        sentJson = JsonConvert.SerializeObject(inv, Formatting.None, new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });

        request.Content = new StringContent(JsonConvert.SerializeObject(inv), Encoding.UTF8, "application/json");

        HttpResponseMessage response = await _httpClient.SendAsync(request);

        string content = await response.Content.ReadAsStringAsync();

        if (response.StatusCode != System.Net.HttpStatusCode.Created)
        {
            Error error = JsonConvert.DeserializeObject<Error>(content);
            throw new Exception(CompactError("Invoicing-create", response.StatusCode, error));
        }
        CreateResponse invoiceCreated = JsonConvert.DeserializeObject<CreateResponse>(content);

        t.InvoiceId = invoiceCreated.href.Split('/').Last();

        return true;
    }

我发现了问题。 这是一个域问题。它已发送到贝宝服务器上的许多请求。如此经典的拒绝服务。
