fastrpc的使用
首先为了防止项目更新我把它fork到我的git下面的了，项目地址
git@github.com:cxapython/fastrpc.git。
这是一个python和js的项目，首先使用python3，安装所需要的依赖问题
然后直接，启动sekiro服务
python3 main.py
之际将client.js文件放到油猴脚本。
例如下面的xhs的。x-s获取

var url_path = params.url_path
var param = params.param

resolve(result);
})
然后在python中这样使用
这里以post请求为例，参数action和param是固定的名称。
action就是请求下面方法的内容,这里是get_headers。
post_data = {"action": "get_headers", "param": {"url_path": url_path, "param": json_data}}
response = None
for i in range(10):
try:
response = requests.post("http://localhost:8000/invoke", headers=headers2,
data=json.dumps(post_data, ensure_ascii=False, separators=(',', ':')).encode(),
timeout=3)
break
except Exception:
pass
请求的方法就是上面的js的这段代码
client.registerAction("get_headers",function(request, resolve,reject ){
console.log("request",request)
//这里面写逻辑就好了
var params = request.param
var url_path = params.url_path
var param = params.param
var result = window._webmsxyw(url_path,params)
resolve(result); //返回内容
})
