Question

我正在尝试按以下方式配置HTTP活动性探针：

livenessProbe:
          httpGet:
              path: /rest/sends/get?source=mwTESt2VP3Q9M99GNWYvvaLQ1owrGTTjTb #sends API to test address
              port: 4000
              httpHeaders:
                - name: Authorization
                  value: Basic cnBjOnUzSGRlM0xvaWI1SGpEcTFTZGVoQktpU1NBbHE=
          initialDelaySeconds: 60 #wait this period after staring fist time
          periodSeconds: 30  # polling interval
          timeoutSeconds: 30    # wish to receive response within this time period

此处，URL路径包含查询参数以及身份验证标头（用户名：密码的base64编码）

但是，出现以下错误：

 ERROR in app: Exception on /rest/sends/get [GET] (http 500)

我登录到Pod后检查它是否确实与状态代码200兼容

curl http://username:password@localhost:4000/rest/sends/get?source=mwTESt2VP3Q9M99GNWYvvaLQ1owrGTTjTb

这个问题可能类似于这个Kubernetes liveness probes with query string parameters

但是，据此应该已经解决。我正在主节点和其他节点上的Google cloud version: 1.10.7-gke.2上使用Kubernetes。

我想念什么吗？

在服务器访问日志中，出现以下错误

服务器实际上是交易对手服务器https://github.com/CounterpartyXCP/counterparty-lib

我不确定是什么问题。

Answer 1

我将此标头添加到了请求中

public object this[int index] { get => throw new NotImplementedException(); set => throw new NotImplementedException(); }

public bool IsReadOnly => throw new NotImplementedException();

public bool IsFixedSize => throw new NotImplementedException();

public int Count => throw new NotImplementedException();

public object SyncRoot => throw new NotImplementedException();

public bool IsSynchronized => throw new NotImplementedException();

public int Add(object value)
{
    throw new NotImplementedException();
}

public void Clear()
{
    throw new NotImplementedException();
}

public bool Contains(object value)
{
    throw new NotImplementedException();
}

public void CopyTo(Array array, int index)
{
    throw new NotImplementedException();
}

public IEnumerator GetEnumerator()
{
    throw new NotImplementedException();
}

public int IndexOf(object value)
{
    throw new NotImplementedException();
}

public void Insert(int index, object value)
{
    throw new NotImplementedException();
}

public void Remove(object value)
{
    throw new NotImplementedException();
}

public void RemoveAt(int index)
{
    throw new NotImplementedException();
}

现在可以正常工作了。

如您所见，服务器在返回{unicodify_header_value“类HttpHeaders的函数getitem的最后一行登录。找不到名称“ HTTP_ACCEPT”，这是您的“ < strong> httpHeaders ”配置。好收获。

在kubernetes中的http liveness和readiness探针中传递url查询参数
