通过字符串设置 Cookie答案

【问题标题】：Set Cookies via String通过字符串设置 Cookie

【问题描述】：

我想使用 requestjs 在多个 javascript 文件甚至多个服务器之间发出请求并共享 cookie。出于这个原因，我将 cookie 作为字符串存储在数据库中，并在需要时检索它们。

字符串看起来像这样，应该符合tough-cookie

[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]

如何让 requestjs 使用这些 cookie？ tough-cookie 对象有一个方法 fromJSON(string) 我想这是我需要的。

所以我认为我应该能够做到

var cookies = '[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]';

var j = request.jar();
j.fromJSON(cookies);

request.get({ url: 'https:/url.com', jar : j}, 
function(error, response, body) {
         console.log(body);
});

但这给出了错误TypeError: j.fromJSON is not a function

如何获取使用从数据库中获取的 cookies 字符串的请求？

【解决方案1】：

可以直接访问对象输入cookies，但不知道是不是最好的解决方案：

TOUGH = require('tough-cookie');

var cookies = '[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]';

var j = request.jar();
cookies = JSON.parse(cookies);
for(i = 0; i < cookies.length; i++) {
    var cookie = new TOUGH.Cookie(cookies[i]);
       var domain = cookie.canonicalizedDomain();

       if (!j._jar.store.idx[domain]) {
        j._jar.store.idx[domain] = {};
    }
    if (!j._jar.store.idx[domain][cookie.path]) {
        j._jar.store.idx[domain][cookie.path] = {};
    }

j._jar.store.idx[domain][cookie.path][cookie.key] = cookie;
}

//this will use the set cookies

request.get({ url: 'https:/url.com', jar : j}, 
function(error, response, body) {
         console.log(body);
});
