从 DSS 服务器获取 json 响应时出错:“使用 JsonWriter 写入输出流时出错"、“详细信息":“" [英] Error in getting json response from DSS server: "Error while writing to the output stream using JsonWriter","detail":""

问题描述

从我的 dss 服务请求 json 响应时出现以下错误.

I'm getting following error while requesting json response from my dss service.

{"Fault":{"faultcode":"soapenv:Server","faultstring":"Error while writing to the output stream using JsonWriter","detail":""}}

我通过的 curl 请求是

curl request which i pass is

curl -X GET -H "Accept:application/json" -H "Content-Type:application/json" http://localhost:9764/services/userdetails/test

如果我删除接受标头，我会得到正确的 xml 响应.

I am getting the proper xml response if i remove accept header.

奇怪的是，如果我在同事的笔记本电脑上运行相同的 dss 服务，我会使用上述 curl 命令获得正确的 json 响应.由于我的电脑出现此错误，我的电脑中的某些配置已更改.

Strange thing is if i am running the same dss service from my colleague's laptop, i m getting the proper json response with that above curl command. Some configuration has changed in my pc because of that i'm getting this error in my pc.

我无法在我的电脑中找到发生了什么变化，因此我收到了这个错误.

I am not able to find what has changed in my pc because of which i'm getting this error.

推荐答案

我最近也遇到了同样的情况.我希望调试并找到原因，但还没有机会.

I also experienced the same recently. I was hoping to debug and find the cause, but didn't get a chance yet.

但是，更改 respository/conf/axis2/axis2.xml 中的 application/json 格式化程序和发送器实现解决了该问题.为此，您可以取消注释/注释掉以下内容.

However, changing application/json formatter and sender implementations in respository/conf/axis2/axis2.xml resolved the issue. For that, you can uncomment/comment-out followings.

<messageFormatter contentType="application/json"
                  class="org.apache.axis2.json.JSONMessageFormatter"/>
<!--messageFormatter contentType="application/json"
                          class="org.apache.axis2.json.gson.JsonFormatter" /-->


<messageBuilder contentType="application/json"
                class="org.apache.axis2.json.JSONOMBuilder"/>
<!--messageBuilder contentType="application/json"
                        class="org.apache.axis2.json.gson.JsonBuilder" /-->

希望这会有所帮助.
