Javascript 用jest响应本机测试，如何制作同构的获取发送cookie

我正在构建一个react本机应用程序，它使用用户帐户连接到论坛，并从那里获取一些数据。我试图让

fetch

在我的测试中使用cookies与

jest

，但看起来好像不起作用

我使用

isomorphic fetch

在我的测试环境中提供

fetch

我的代码如下：

jest.setup.js

：

import "isomorphic-fetch"

var iconv  = require('iconv-lite');                              
var Entities = require("html-entities").AllHtmlEntities;         
const entities = new Entities();  


function _textToUTF8(t) {                                             
    return entities.decode(iconv.decode(t, "windows-1252"));          
}                                                                     

function _generateFormData(d) {             
    var output = [];                        
    for (var i in d) {                      
        output.push(i + "=" + d[i]);        
    }                                       
    return output.join("&");                
}    

function _isLoggedIn(t) {
    return t.indexOf("logout") >= 0 ? true : false;
}


function _getWebpage(url, r) {                                 
    return new Promise((resolve, reject) => {

            response.buffer().then((buffer) => {     
                var t = _textToUTF8(buffer);

看起来由于某种原因没有发送任何cookie，它在第一个请求中按预期登录，但第二个请求没有登录。我怎样才能让它工作

顺便说一句，如果我更改

凭证：include

为

凭证：同源

，它也不起作用。

找到这个问题了吗？。看起来我们必须手动读取并设置cookie。
