請求服務(wù)器時川尖，系統(tǒng)只會選擇與該服務(wù)器的證書請求相匹配的證書。
可能會匹配到多個證書的各自頒發(fā)機構(gòu)茫孔。

可以設(shè)置AutoSelectCertificateForUrls來自動選擇哪個證書的頒發(fā)機構(gòu)叮喳。
設(shè)置方法chrome瀏覽器地址欄輸入chrome://flags/，然后對Enable policy management page為true缰贝。
接著地址欄輸入chrome://policy-tool/馍悟，然后AutoSelectCertificateForUrls設(shè)值。
值的格式是

{"pattern":"https://www.example.com","filter":{"ISSUER":{"CN":"certificate issuer name"}}}

certificate issuer name是指證書的頒發(fā)機構(gòu)剩晴。

非要指定某個證書锣咒，參考以下代碼：

'use strict';

const puppeteer = require('puppeteer');
const request = require('request');
const fs = require('fs');

(async () => {
    const browser = await puppeteer.launch();
    let page = await browser.newPage();

    // Enable Request Interception
    await page.setRequestInterception(true);

    // Client cert files
    const cert = fs.readFileSync('/path/to/cert.crt.pem');
    const key = fs.readFileSync('/path/to/cert.key.pem');

    page.on('request', interceptedRequest => {
        // Intercept Request, pull out request options, add in client cert
        const options = {
            uri: interceptedRequest.url(),
            method: interceptedRequest.method(),
            headers: interceptedRequest.headers(),
            body: interceptedRequest.postData(),
            cert: cert,
            key: key
        };

        // Fire off the request manually (example is using using 'request' lib)
        request(options, function(err, resp, body) {
            // Abort interceptedRequest on error
            if (err) {
                console.error(`Unable to call ${options.uri}`, err);
                return interceptedRequest.abort('connectionrefused');
            }

            // Return retrieved response to interceptedRequest
            interceptedRequest.respond({
                status: resp.statusCode,
                contentType: resp.headers['content-type'],
                headers: resp.headers,
                body: body
            });
        });

    });

    await page.goto('https://client.badssl.com/');
    await browser.close();
})();

但是mac導(dǎo)出證書和key是個大問題啊
