虽然我过去集成了几个支付处理器和购物车，但这个 Google Checkout API 集成对我来说并不顺利。即使我使用诊断链接，我也会收到来自 Google 的 400 响应。我确定我的 URL 有问题，但我似乎无法弄清楚是什么。我正在使用沙盒商家 ID 和密钥。

有人可以帮我看看我在做什么来得到这个 400 响应吗？

我正在使用 Java 并从服务器发布，因此我正在调用服务器到服务器 API 链接：

https://sandbox.google.com/checkout/api/checkout/v2/merchantCheckout/Merchant/%SANDBOXID%

<?xml version="1.0" encoding="UTF-8"?>
<checkout-shopping-cart xmlns="http://checkout.google.com/schema/2">
    <shopping-cart>
        <merchant-private-data>
            <merchant-note>8Ra8fw4tBaOdP4v3lseykKO6crR0dFqhzWV0EmqKuVuQaN1w0mcScAAR71pbexXlVnrwpP8wNzehuc7wz3KO9JM6xfedW8106olarCZcZBs=</merchant-note>
        </merchant-private-data>
        <items>
            <item-name>MyName : MySubname</item-name>
            <item-description>Weigh in on this year's...</item-description>
            <unit-price currency="USD">100</unit-price>
            <quantity>1</quantity>
         </items>
     </shopping-cart>
</checkout-shopping-cart>

我正在使用 Java 发布这些数据。在下面的代码中，上面的url是代码中的sandboxLink，checkReq是XML post...

    public static String postCheckoutReqData(String userID, String gameName, boolean test) {

    String checkRequest = GoogleCheckoutXML.getCheckoutRequestXML(userID, gameName);

    if(checkRequest.indexOf("error,") != -1) return checkRequest;

    URL url = null;
    try {           
        String baseCodeString;          
        if(test) {
            url = new URL(GoogleCheckoutXML.sandboxLink + GoogleCheckoutXML.sandboxMerchID);
            baseCodeString = GoogleCheckoutXML.sandboxMerchID + ":" + GoogleCheckoutXML.sandboxMerchKey;
        }
        else {
            url = new URL(GoogleCheckoutXML.productionLink + GoogleCheckoutXML.merchantID);
            baseCodeString = GoogleCheckoutXML.merchantID + ":" + GoogleCheckoutXML.merchantKey;
        }
        //url = new URL(GoogleCheckoutXML.diagnose);
        byte[] bytes = (baseCodeString.getBytes());
        baseCodeString = new Base64().encodeAsString(bytes);
        URLConnection conn = url.openConnection();          
        conn.setDoOutput(true);
        conn.setRequestProperty("Authorization", "Basic " + baseCodeString);
        conn.setRequestProperty("Content-Type", "application/xml; charset=UTF-8");
        conn.setRequestProperty("Accept", "application/xml; charset=UTF-8");

        OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
        wr.write(checkRequest);
        wr.flush();

        // Get the response
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
            line = line + rd.readLine();
        }

        wr.close();
        rd.close();
        return line;
    } 
    catch (Exception e) {   
        e.printStackTrace();
        return "error,Purchase Error posting communcation failed";
    }

Tomcat 中的实际堆栈跟踪是：

我想我已经解决了一个类似的问题 - 它可能是也可能不是你的......

  1. 检查返回码：

    int code = conn.getResponseCode(); // 整数（在上面给出的情况下为 400） \String msg = conn.getResponseMessage(); // 字符串（在您上面给出的情况下将是“错误请求”

  2. 检查更多细节

    InputStream in = new BufferedInputStream(conn.getErrorStream());

    阅读以查看提供了哪些进一步的信息 - 我发现它非常有帮助！

  3. 就我而言，我精心准备的 xml 在途中某处丢失了引号，<xml version="1.0" ... >一开始就破坏了右边，从那时起就造成了严重破坏......
