AnyProxy 修改requestData（JSON）
github上的demo
直接返回了一个自定义的 'i-am-anyproxy-modified-post-data'
module.exports = {
summary: 'Rule to modify request data',
*beforeSendRequest(requestDetail) {
if (requestDetail.url.indexOf('http://httpbin.org/post') === 0) {
return {
requestData: 'i-am-anyproxy-modified-post-data'
};
}
},
};现实中，我通常是需要针对原有的请求data做一部分的修改，例如在请求json中，增加一个新的key：value
操作步骤：
1.Buffer数据 toString()成普通字符串
2.将字符串转换成jsonObect
3.针对jsonObject操作，增 删 改 key：value值
4.将修改后的jsonObject toString成字符串，直接做接口返回（requestData：新改后的json字符串）
参考如下代码（modify_request_data.js）：
module.exports = {
summary: 'Rule to modify request data',
*beforeSendRequest(requestDetail) {
console.log('已经进入拦截')
if (requestDetail.url.endsWith('/api/shop/front/trcOrder/submitOrder') ||
requestDetail.url.endsWith('/api/loan/front/loan-application') ) {
json = requestDetail.requestData.toString()
console.log("请求前json+++++++++++start++++++++++++++++++++++++++++++++++++")
console.log(json)
console.log("请求前json+++++++++++end++++++++++++++++++++++++++++++++++++++")
json_obj = JSON.parse(json)
//修改请求参数，增加"remark"="nancyaddvalue"这个key：value值
json_obj["remark"]="nancyaddvalue"
console.log("修改请求data的json+++++++++++start++++++++++++++++++++++++++++++++++++")
console.log(json_obj)
console.log("修改请求data的json+++++++++++end++++++++++++++++++++++++++++++++++++++")
return {
//返回的requestData不需要buffer形式，string类型即可
requestData: JSON.stringify(json_obj)
};
}
},
};
执行 anyproxy -i --rule modify_request_data.js
发起请求，结果如下
[AnyProxy Log][2018-10-12 19:12:03]: received request to: POST 10.10.10.10:81/api/shop/front/trcOrder/submitOrder
已经进入拦截
请求前json+++++++++++start++++++++++++++++++++++++++++++++++++
{"OrderNo":"1234","period":12}
请求前json+++++++++++end++++++++++++++++++++++++++++++++++++++
修改请求data的json+++++++++++start++++++++++++++++++++++++++++++++++++
{ shopOrderNo: '1234',
period: 12,
remark: 'nancyaddvalue' }
修改请求data的json+++++++++++end++++++++++++++++++++++++++++++++++++++
requestDetail的结构，可以看出requestDetail.requestData 的类型是Buffer
