如何获得 Groovy RestClient 失败响应的完整响应

Question

目前，我收到 HttpResponseException，它只有 statusCode。我怎样才能得到完整的回复？

这是我正在使用的代码

restClient = new RESTClient("http://${Server}")
try {
    HttpResponseDecorator resp = restClient.post(path,body,requestContentType)     
        as HttpResponseDecorator
    return JSONObject.fromObject(resp.getData()).get("topKey","");
    }
catch (HttpResponseException e) {
            error(e.toString())
    }

而且它只输出这个：

[oaf.error] groovyx.net.http.HttpResponseException: Internal Server Error

添加自定义失败响应处理程序：

        restClient = new RESTClient("http://${Server}")
        restClient.handler.failure = { resp, data ->
            resp.setData(data)
            String headers = ""
            resp.headers.each {
                headers = headers+"${it.name} : ${it.value}\n"
            }
            throw new HttpResponseException(resp.getStatus(),"HTTP call failed. Status code: ${resp.getStatus()}\n${headers}\n"+
                                            "Response: "+(resp as HttpResponseDecorator).getData())
        }

实际上，您可以从抛出的异常中提取完整的响应。例如，如果您捕获的异常是 e 并且响应正文 JSON 应该包含一个名为 myCustomErrorCode 的字段，您可以通过查看 e.response.data.myCustomErrorCode 除了 [=13] 来检查它的值=].
