1、错误描述
严重:Servlet.service() for servlet [clientServlet] in context with path [/User] threw exception
net.at.json.JSONException:JSONArray text must start with '[' at character 1 of 127.0.0.1
2、错误原因
JSONArray json = JSONArray.fromObject(ip);
在servlet传参数到Flex中,利用JSON格式传参,但是ip是一个String类型,不符合JSON对象格式
3、解决办法
在servlet中利用PrintWriter
PrintWriter out = response.getWriter();
out.println(ip);
