#### 准备工作 ####

首先得申请一个微信公众号，然后用浏览器登录之后，来到关键词回复页面。利用cookie获取工具导出当前的cookie。

点击导出当前domain的所有cookie

![image-20201029112051599][image-20201029111954415]

导出来的cookie是一个数组，直接复制到一个地方备用即可

#### 环境构建 ####

使用全局代理，利用npm下载puppeteer

npm i puppeteer@3.0.0

由于下载puppeteer的时候会下载chromium，所以需要全局代理，不下载chromium也可以直接下载puppeteer-core

npm i puppeteer-core

#### 整活 ####

##### 打开页面 #####

let browser = await puppeteer.launch(launchOptions);
    let page = await browser.newPage();
    for (let i = 0; i < cookies.length; i++) {
        await page.setCookie(cookies[i]);
    }
    await page.goto(url);
    await page.waitForSelector('html');
    await page.content();
    let title = await page.title();

##### 点击添加回复 #####

await page.$$eval('.weui-desktop-layout__extra', clickAddButton);
    async function clickAddButton(nodes) {
        let cnt = 0;
        for (let node of nodes) {
            cnt++;
            if (cnt === 1) continue;
            let treeWalker = document.createTreeWalker(
                node,
                NodeFilter.SHOW_ELEMENT,
                {
                    acceptNode: function (node2) {
                        return NodeFilter.FILTER_ACCEPT;
                    }
                },
                false
            );
            while (treeWalker.nextNode()) {
                let current = treeWalker.currentNode;
                if (current.tagName.toLowerCase() === 'button' && current.innerHTML === '添加回复') {
                    await current.click();
                    return true;
                }
            }
        }
        return false;
    }

##### 填写规则和匹配 #####

await page.type('.weui-desktop-form__input', val.group + '', {delay: 100});
    await page.waitFor(1000);
    await page.type('[placeholder=输入关键词]', val.title.split('-')[0] + '', {delay: 100});
    await page.waitFor(1000);

#### 点击添加文本回复信息的按钮 ####

await page.$$eval('.weui-desktop-msg-sender__tab_text', addTxt);
    async function addTxt(nodes) {
        for (let node of nodes) {
            await node.click();
            return true;
        }
        return false;
    }

##### 在内容区键入回复内容 #####

await page.focus('.edit_area');
    await page.keyboard.type('aaa：' + val.title.split('-')[0].trim(), {delay: 100});
    await page.keyboard.press('Enter');
    await page.keyboard.type('bbb：' + val.title.split('-')[1].trim(), {delay: 100});
    await page.keyboard.press('Enter');
    await page.keyboard.type('ccc：' + val.url, {delay: 100});
    await page.keyboard.press('Enter');
    await page.keyboard.type('ddd：' + val.code, {delay: 100});
    await page.keyboard.press('Enter');
    await page.keyboard.type('eee：' + val.id, {delay: 100});

##### 利用xpath点击按钮 #####

await page.waitForXPath('//*[@id="app"]/div[3]/div[2]/div[2]/form/div[3]/div/div/div[3]/div[1]/div/div[3]/button[1]');
    let elHandles = await page.$x('//*[@id="app"]/div[3]/div[2]/div[2]/form/div[3]/div/div/div[3]/div[1]/div/div[3]/button[1]');
    for (let handle of elHandles) {
        handle.click({delay: 100});
    }

##### 利用xpath 点击保存按钮 #####

await page.waitForXPath('//*[@id="app"]/div[3]/div[2]/div[2]/div/button[1]');
    let elHandle1s = await page.$x('//*[@id="app"]/div[3]/div[2]/div[2]/div/button[1]');
    for (let handle of elHandle1s) {
        handle.click({delay: 100});
    }

就搞定了
