我正在尝试验证服务器端的付款收据.我得到了{"status":21002, "exception":"java.lang.IllegalArgumentException"}回报

这是代码:

private final static String _sandboxUriStr = "https://sandbox.itunes.apple.com/verifyReceipt";

public static void processPayment(final String receipt) throws SystemException
{
    final BASE64Encoder encoder = new BASE64Encoder();
    final String receiptData = encoder.encode(receipt.getBytes());


    final String jsonData = "{\"receipt-data\" : \"" + receiptData + "\"}";

    System.out.println(receipt);
    System.out.println(jsonData);

    try
    {
        final URL url = new URL(_sandboxUriStr);
        final HttpURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setRequestMethod("POST");
        conn.setDoOutput(true);
        final OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
        wr.write(jsonData);
        wr.flush();

        // Get the response
        final BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); …

我有一个巨大的生成的shell脚本,有很多行

java -jar <app_jar> <params>

每次调用都会向Dock提供一个java图标,使得活动应用程序在调用java app的每一行都会失去焦点

有没有办法静静地运行它？

Java应用程序是一个单一的,简单的控制台应用程序,带有文件IO例程,不会创建任何窗口

我正在尝试使用 jq 提取 kubeconfig 数据。

kubectl config view --raw -o json | jq ...

有一个这样的json：

{
    "kind": "Config",
    "apiVersion": "v1",
    "preferences": {},
    "clusters": [
        {
            "name": "some-name",
            "cluster": {
                "server": "https://some-url",
                "certificate-authority-data": "some-cert"
            }
        },
      {
          "name": "another-name",
          "cluster": {
              "server": "https://another-url",
              "certificate-authority-data": "another-cert"
          }
      }
    ],
    "users": [
        {
            "name": "some-name",
            "user": {
                "username": "some-user",
                "password": "some-password"
            }
        },
        {
            "name": "another-name",
            "user": {
                "username": "another-user",
                "password": "another-password"
            }
        }
    ],
    "contexts": [],
    "current-context": "some-context"
}

问题 1： 对于给定的名称，“some-name”，我想提取 …
