京东 rpc调用h5st

一，jsrpc程序下载，双击启动

二，注入JS，构建通信环境（/resouces/JsEnv_De.js）

var rpc_client_id, Hlclient = function (wsURL) {
    this.wsURL = wsURL;
    this.handlers = {
        _execjs: function (resolve, param) {
            var res = eval(param)
            if (!res) {
                resolve("没有返回值")
            } else {
                resolve(res)
            }
        }
    };
    this.socket = undefined;
    if (!wsURL) {
        throw new Error('wsURL can not be empty!!')
    }
    this.connect()
}
Hlclient.prototype.connect = function () {
    if (this.wsURL.indexOf("clientId=") === -1 && rpc_client_id) {
        this.wsURL += "&clientId=" + rpc_client_id
    }
    console.log('begin of connect to wsURL: ' + this.wsURL);
    var _this = this;
    try {
        this.socket = new WebSocket(this.wsURL);
        this.socket.onmessage = function (e) {
            _this.handlerRequest(e.data)
        }
    } catch (e) {
        console.log("connection failed,reconnect after 10s");
        setTimeout(function () {
            _this.connect()
        }, 10000)
    }
    this.socket.onclose = function () {
        console.log('rpc已关闭');
        setTimeout(function () {
            _this.connect()
        }, 10000)
    }
    this.socket.addEventListener('open', (event) => {
        console.log("rpc连接成功");
    });
    this.socket.addEventListener('error', (event) => {
        console.error('rpc连接出错,请检查是否打开服务端:', event.error);
    })
};
Hlclient.prototype.send = function (msg) {
    this.socket.send(msg)
}
Hlclient.prototype.regAction = function (func_name, func) {
    if (typeof func_name !== 'string') {
        throw new Error("an func_name must be string");
    }
    if (typeof func !== 'function') {
        throw new Error("must be function");
    }
    console.log("register func_name: " + func_name);
    this.handlers[func_name] = func;
    return true
}
Hlclient.prototype.handlerRequest = function (requestJson) {
    var _this = this;
    try {
        var result = JSON.parse(requestJson)
    } catch (error) {
        console.log("请求信息解析错误", requestJson);
        return
    }
    if (result["registerId"]) {
        rpc_client_id = result['registerId']
        return
    }
    if (!result['action'] || !result["message_id"]) {
        console.warn('没有方法或者消息id,不处理');
        return
    }
    var action = result["action"], message_id = result["message_id"]
    var theHandler = this.handlers[action];
    if (!theHandler) {
        this.sendResult(action, message_id, 'action没找到');
        return
    }
    try {
        if (!result["param"]) {
            theHandler(function (response) {
                _this.sendResult(action, message_id, response);
            })
            return
        }
        var param = result["param"]
        try {
            param = JSON.parse(param)
        } catch (e) {
        }
        theHandler(function (response) {
            _this.sendResult(action, message_id, response);
        }, param)
    } catch (e) {
        console.log("error: " + e);
        _this.sendResult(action, message_id, e);
    }
}
Hlclient.prototype.sendResult = function (action, message_id, e) {
    if (typeof e === 'object' && e !== null) {
        try {
            e = JSON.stringify(e)
        } catch (v) {
            console.log(v)//不是json无需操作
        }
    }
    this.send(JSON.stringify({"action": action, "message_id": message_id, "response_data": e}));
}
window.demo = new Hlclient("ws://127.0.0.1:12080/ws?group=zzz");

三，打开控制台注入js 方法

四，python调用，传入参数，获取返回的加密参数

python 复制代码

import json
from time import time
import requests
import hashlib

def sha256_hash(message):
    # 创建SHA-256对象
    sha256 = hashlib.sha256()

    # 更新哈希对象的内容
    sha256.update(message.encode('utf-8'))

    # 计算哈希值
    hash_value = sha256.hexdigest()

    return hash_value
