最近在测试服务器上经常出现前端发了ajax请求后，状态200，response为空，同时伴随着其他一些问题。不由得怀疑起来。在后端代码调试发现，后端服务返回了请求，发出了响应。那什么原因呢？
就想着能不能把请求拿出来发送一下。chrome还真有这个手段.
通过这种方式可以拿到如下的请求内容

然后在终端窗口去执行
例如：
curl -l -H "Content-type: application/json" -X POST -d '{"ver": "1.0","soa":
{"req":"123"},"iface":"me.ele.lpdinfra.prediction.service.PredictionService","method":"restaurant
