我从 belo 博客 URL 获得了帮助。

错误是 - 在响应对象中，当我在 xp-64 位(端口和 iis6 两者)、window server 2008(iis7 32 位模式)上运行相同的代码时，我得到“resp.Token is null”

但在 win-7 32 位 iis7 和端口上运行良好(没有错误， token 是 nut null 获取值(value))

我的代码在下面。

  protected void btnPaypal_Click(object sender, EventArgs e)
{

    CustomSecurityHeaderType type = new CustomSecurityHeaderType();

    type.Credentials = new UserIdPasswordType()
    {

        Username = "removed",
        Password = "removed",
        Signature = "removed"
    };

    SetExpressCheckoutRequestDetailsType sdt = new SetExpressCheckoutRequestDetailsType();
    sdt.NoShipping = "1";
    PaymentDetailsType pdt = new PaymentDetailsType()
    {
        OrderDescription = "Payment Details Sushant",
        OrderTotal = new BasicAmountType()
        {
            currencyID = CurrencyCodeType.USD,
            Value = "100.00"
        }
    };

    sdt.PaymentDetails = new PaymentDetailsType[] { pdt };
    sdt.CancelURL = "http://localhost/OAT/Default.aspx";
    sdt.ReturnURL = "http://localhost/OAT/ExpressCheckoutSuccess.aspx";

    SetExpressCheckoutReq req = new SetExpressCheckoutReq()
    {
        SetExpressCheckoutRequest = new SetExpressCheckoutRequestType()
        {
            SetExpressCheckoutRequestDetails = sdt,
            Version = "60.0"
        }
    };
    PayPalAPIAAInterfaceClient paypalAAInt = new PayPalAPIAAInterfaceClient();
    var resp = paypalAAInt.SetExpressCheckout(ref type, req);
    if (resp.Errors != null && resp.Errors.Length > 0)
    {
        // errors occured
        throw new Exception("Exception(s) occured when calling PayPal. First exception: " +
            resp.Errors[0].LongMessage + resp.Errors.Length.ToString());
    }

// error is here.. that resp.Token is null on xp-64 bit port and iis6 both, but running fine on win-7 32 bit iis7 and port, and w

    Response.Redirect(string.Format("{0}?cmd=_express-checkout&token={1}",
            "https://www.paypal.com/cgi-bin/webscr", resp.Token));


}

Answer 1

在 PayPal Web Reference 的文件夹中，在文本编辑器中打开 Reference.cs 文件并搜索“System.Xml.XmlElement Any”

您会注意到如下代码:

[System.Xml.Serialization.XmlElementAttribute(Order=6)]
    public System.Xml.XmlElement Any {
        get {
            return this.anyField;
        }
        set {
            this.anyField = value;
            this.RaisePropertyChanged("Any");
        }
    }

现在替换

[System.Xml.Serialization.XmlElementAttribute(Order=6)]

与

[System.Xml.Serialization.XmlIgnoreAttribute()]

重新编译后运行您的应用程序。

您现在将看到 resp.Token 填充了所需的值
