Node.js：如何重啟 Tor 客戶端

Question

我有一個簡單的腳本，它使用Puppeteer和Tor客戶端來導航具有不同 IP 的 web：

const puppeteer = require('puppeteer-extra');
const puppeteer_stealth = require('puppeteer-extra-plugin-stealth');
const puppeteer_proxy = require('puppeteer-page-proxy')
const exec = require('child_process').exec

puppeteer.use(puppeteer_stealth())

async function test() {
    // This function will test the bot and ooutput the results
    const browser = await puppeteer.launch({
        headless: true,
        args: ['--no-sandbox']
    });
    const page = (await browser.pages())[0];
    console.log('Running test...');
    
    // IP test
    console.log('\nIP test')

    await page.goto('https://api.ipify.org/');
    const original_ip = await page.evaluate(() => { return document.querySelector('body').children[0].innerHTML })
    console.log('Original IP: ' + original_ip)
    
    await puppeteer_proxy(page, 'socks://127.0.0.1:9050');
    await page.reload();
    const tor1_ip = await page.evaluate(() => { return document.querySelector('body').children[0].innerHTML })
    console.log('Tor #1 IP: ' + tor1_ip)

    exec('sudo /etc/init.d/tor restart');
    await page.reload()
    const tor2_ip = await page.evaluate(() => { return document.querySelector('body').children[0].innerHTML })
    console.log('Tor #2 IP: ' + tor1_ip)

    await browser.close()
}

test()

當我想重新啟動 Tor 客戶端以擁有一個新的 IP 時，問題就來了。通常我會在 Linux 終端中使用以下命令執行此操作：

sudo /etc/init.d/tor restart

所以我找到了一種在 Node.js 中使用child_process執行命令的方法，但我無法讓它工作。 這是我的代碼的 output：

Running test...

IP test
Original IP: ***.***.***.*** // censored by me
Tor #1 IP: ***.***.***.*** // censored by me
/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:221
            throw new Error('Evaluation failed: ' + helper_js_1.helper.getExceptionMessage(exceptionDetails));
                  ^

Error: Evaluation failed: TypeError: Cannot read properties of undefined (reading 'innerHTML')
    at __puppeteer_evaluation_script__:1:59
    at ExecutionContext._evaluateInternal (/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:221:19)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async ExecutionContext.evaluate (/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:110:16)
    at async test (/home/flavio/Documents/arbitrage-betting/index.js:31:21)

我試圖自己解決問題，我什至實施了 tor_request但仍然無法正常工作。

Answer 1

我認為錯誤不是關於重新啟動它關於網站的評估？！

編輯哇，感謝您下次使用最佳設計沒有得到答案時有這么多不喜歡，如果您能閱讀：

/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:221
            throw new Error('Evaluation failed: ' + helper_js_1.helper.getExceptionMessage(exceptionDetails));
                  ^

Error: Evaluation failed: TypeError: Cannot read properties of undefined (reading 'innerHTML')
    at __puppeteer_evaluation_script__:1:59
    at ExecutionContext._evaluateInternal (/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:221:19)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async ExecutionContext.evaluate (/home/flavio/Documents/arbitrage-betting/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:110:16)
    at async test (/home/flavio/Documents/arbitrage-betting/index.js:31:21)

它說它在第 31:21 行的評估中有錯誤，我認為應該是：

const tor2_ip = await page.evaluate(() => { return document.querySelector('body').children[0].innerHTML })

所以...請指定您要查找的內容，或者只是告訴我我的答案有什么錯誤謝謝:)

Answer 2

當您記錄“Tor #2 IP:”時，您在下一行中指向 tor1_ip：console.log('Tor #2 IP:' + tor1_ip) 所以它應該是：console.log('Tor #2 IP:' + tor2_ip)
