WSO2 - ESB通过代理发布请求失败

时间：2017-09-22 08:44:46

标签： wso2esb esb

大家好，你能帮助我解决我的WSO2 - ESB问题。

我在UAT环境中遇到以下错误，但在我的SIT环境中没有。我需要提示为什么会发生这种情况所以我可以更改我的CAR文件或在需要时将正确的配置添加到我们的服务器。

由于某些原因，当客户端执行Post请求时，我遇到超时错误。检查日志后，我发现它们是一个错误，表明Payload无法写为JSON。这不会发生在GET请求中，所以我迷路了。我还可以确认请求是使用GET / POST在后端发送的。

请注意，以下服务器不存在app03 / app04，因此无法连接到这些服务器（我们的PRD环境中只有2台UAT服务器，但有4台服务器）。

我不明白为什么这只发生在Post请求中，如果我需要修改我的代码或在WSO2-ESB服务器中设置一些内容。

如有任何澄清或其他信息，请不要犹豫。

感谢您的帮助

答案 0 :(得分：0)

使用＆＃39; targetURL＆＃39;是不正确的。而是在<send>中定义端点，例如

<send>
  <endpoint key="XXXX-ws_LBEP" />
</send>
