场景:用于开发人员应用注册的Web表单,包含两部分工作流程.

第1页:填写开发者应用程序详细信息,然后单击按钮以在新选项卡中创建应用程序ID,该ID将打开...

第2页:App ID页面.我需要从此页面复制App ID,然后关闭选项卡并返回到第1页并填写App ID(从第2页保存),然后提交表单.

我了解基本用法 - 如何打开第1页并单击打开第2页的按钮 - 但如何在新选项卡中打开第2页时如何处理？

例:

const puppeteer = require('puppeteer');

(async() => {
    const browser = await puppeteer.launch({headless: false, executablePath: '/Applications/Google Chrome.app'});
    const page = await browser.newPage();

    // go to the new bot registration page
    await page.goto('https://register.example.com/new', {waitUntil: 'networkidle'});

    // fill in the form info
    const form = await page.$('new-app-form');

    await page.focus('#input-appName');
    await page.type('App name here');

    await page.focus('#input-appDescription');
    await page.type('short description of app here');

    await page.click('.get-appId'); //opens new tab with Page 2

    // handle …

使用puppeteer,你怎么能以编程方式提交表单？到目前为止,我已经能够使用page.click('.input[type="submit"]')如果表单实际包含提交输入.但是对于不包含提交输入的表单,关注表单文本输入元素和使用page.press('Enter')似乎并不会导致表单提交:

const puppeteer = require('puppeteer');

(async() => {

    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto('https://stackoverflow.com/', {waitUntil: 'load'});
    console.log(page.url());

    // Type our query into the search bar
    await page.focus('.js-search-field');
    await page.type('puppeteer');

    // Submit form
    await page.press('Enter');

    // Wait for search results page to load
    await page.waitForNavigation({waitUntil: 'load'});


    console.log('FOUND!', page.url());

    // Extract the results from the page
    const links = await page.evaluate(() => {
      const anchors = Array.from(document.querySelectorAll('.result-link a'));
      return anchors.map(anchor …

是否有计划在不久的将来支持.NET Core？我的意思是,没有重构我的机器人代码.仍有与之不兼容的组件.

我正在尝试构建skype bot.

我按照给出的文档skype-sdk但未能使用它创建它.无法从机器人获得回复.

const fs = require('fs');
const restify = require('restify');
const skype = require('skype-sdk');

const botService = new skype.BotService({
    messaging: {
        botId: 'xxxxxxxx-xxx-xxx-xxx-xxxxxxxxxxxx',
        serverUrl : "https://example.net",
        requestTimeout : 15000,
        appId: 'xxxxxxxx-xxx-xxx-xxx-xxxxxxxxxxxx',
        appSecret: 'xxxxxxxxxxxxxxxxxxxxxxxx'
    }
});

botService.on('contactAdded', (bot, data) => {
    console.log("bot replay");
    bot.reply('Hello ${data.fromDisplayName}!', true);
});

botService.on('personalMessage', (bot, data) => {
    console.log("person replay");
    bot.reply('Hey ${data.from}. Thank you for your message: "${data.content}".', true);
});

const server = restify.createServer();

server.use(skype.ensureHttps(true));
server.use(skype.verifySkypeCert({}));

server.post('/skbot', skype.messagingHandler(botService));
const port = process.env.PORT || 8080; …

我正在尝试在NodeJS上使用AdaptiveCards npm包以编程方式生成卡,但我没有看到如何生成要传递给消息的JSON.到目前为止,我的代码非常简单:

session.send(new builder.Message(session).addAttachment({
    contentType: "application/vnd.microsoft.card.adaptive",
    content: createCard()
})); 

function createCard() {
    let card = new adaptiveCards.AdaptiveCard({ type: "AdaptiveCard" });

    // add a text block
    card.addItem(new adaptiveCards.TextBlock({
        text: 'Issue #1',
        weight: "bolder",
        size: "medium"
    }));

    return card;
}

我试图打电话给render方法,但它不起作用.我也试着打电话JSON.stringify(card)但是我得到了TypeError: Converting circular structure to JSON消息错误.任何的想法？如果我将JSON传递给内容附件,那么一切正常.

所以我想class多次截取特定的屏幕截图，但它总是会说Session Closed或Terminated，因此我努力实现打开多个实例的多个屏幕截图。

有人至少可以指导如何在同一个浏览器实例上使用多个实例吗？

my code：

const puppeteer = require("puppeteer");

const SELECTOR = ".octicon";

(async () => {
  let screenshotNumber = 0;
  async function screenshots() {
    const browser = await puppeteer.launch({
      headless: true
    });

    try {
      let page = await browser.newPage();
      page.setViewport({ width: 1000, height: 600, deviceScaleFactor: 2 });

      await page.goto("https://github.com/");
      await page.waitForNavigation({ waitUntil: "networkidle" });

      const rect = await page.evaluate(selector => {
        const element = document.querySelector(selector);
        const { x, y, width, height } …
