c# - USPS 地址验证 API 中的授权失败

Question

只是我有一个注册 USPS它提供了 US Address Validation API。我正在使用以下代码获取 XML 响应。

但是，不幸的是 Response 说:

Authorization Failure User 'xxxxxxxxx' is not authorized to use API Verify.USPSCOM::DoAuth.

我是否遗漏了什么？

代码:

void IsValidAddress()
{
    string USPS = "http://production.shippingapis.com/ShippingAPITest.dll?API=Verify&XML=<AddressValidateRequest%20USERID='xxxxxxx'><Address ID='1'><Address1></Address1><Address2>8 Wildwood Drive</Address2><City>Old Lyme</City><State>CT</State><Zip5>06371</Zip5><Zip4></Zip4></Address></AddressValidateRequest>";
    WebClient wsClient = new WebClient();

    byte[] responseData = wsClient.DownloadData(USPS);

    string response = string.Empty;

    foreach (byte item in responseData)
    {
        //this will return the xml response
        response += (char)item;
    }
    string result = response;
    Response.Write(result);
}

注意:用户 ID 是我的个人用户 ID，由 USPS 服务提供商颁发。

要解决此错误，我们需要调用 USPS 并通过向 USPS 发出注册 ID 来请求验证，并且首先您可以向 USPS 发送邮件作为对此问题的反馈。
