我正在通过操纵up的人进行自动测试,该人填写了表格并也检查了验证码。如果验证码不正确,它将刷新为新图像,但是我需要再次处理整个图像,并达到先前用于处理它的功能。
(async function example() {
const browser = await puppeteer.launch({headless: false})
const page = await browser.newPage()
/*-----------NEED TO COME BACK HERE-----------*/
const tessProcess = utils.promisify(tesseract.process);
await page.setViewport(viewPort)
await page.goto('http://www.example.com')
await page.screenshot(options)
const text = await tessProcess('new.png');
console.log(text.trim());
await page.$eval('input[id=userEnteredCaptcha]', (el, value) => el.value = value, text.trim())
await page.$eval('input[id=companyID]', el => el.value = 'val');
const submitBtn = await page.$('[id="data"]');
await submitBtn.click();
try {
var x = await page.waitFor("#msgboxclose");
console.log("Captcha error")
}
catch (e) {
console.error('No Error');
}
if(x){
await page.keyboard.press('Escape');
/*---------GO FROM HERE--------*/
}
})()
我想创建一个循环,以便每当验证码错误时可以再次处理图像
答案 0 :(得分:1)
声明一个布尔变量,该布尔变量指示是否需要重试,并将重复的功能放入检查该变量的while
循环中。如果循环末尾的x
条件不满足,请将tryAgain
设置为false
,这样就不会发生进一步的迭代:
(async function example() {
const browser = await puppeteer.launch({headless: false})
const page = await browser.newPage()
let tryAgain = true; // <--------------------------
while (tryAgain) { // <--------------------------
/*-----------NEED TO COME BACK HERE-----------*/
const tessProcess = utils.promisify(tesseract.process);
await page.setViewport(viewPort)
await page.goto('http://www.example.com')
await page.screenshot(options)
const text = await tessProcess('new.png');
console.log(text.trim());
await page.$eval('input[id=userEnteredCaptcha]', (el, value) => el.value = value, text.trim())
await page.$eval('input[id=companyID]', el => el.value = 'val');
const submitBtn = await page.$('[id="data"]');
await submitBtn.click();
try {
var x = await page.waitFor("#msgboxclose");
console.log("Captcha error")
}
catch (e) {
console.error('No Error');
}
if(x){
await page.keyboard.press('Escape');
/*---------GO FROM HERE--------*/
} else {
tryAgain = false; // <--------------------------
}
}
})()
