Javascript 用2个参数模拟下一个函数？

我正在尝试模拟https。get与嵌套在我的自定义函数

getSecureString（）

中

https.get

返回在其try/catch部分使用的两个json元素。请参阅下面的函数

网上版本

我得到的错误是

Expected: 1
Received: undefined

  26 |     it('should return 1', () => {

问题:

---

有人能找出我为什么会出现上述错误，以及我如何在

https.get（）

中模拟

body

和

res.statusCode

？

这里有一个例子，但如果有什么不清楚的地方，我可能明天会描述它们：）哇！谢谢我有一个问题=）我现在在添加了

httpsGet（）

的输出作为文件。我想，如果我把它包括进去，或者仅仅是

字符串：“not_secret\u string”

，但看到您使用了3

dataCallback（）

s，我开始认为使用

httpsGet.mockResponseData.json

中的内容不会那么容易？顺便问一下，你是如何触发聊天链接的？我已经创建了一个聊天室并将链接粘贴到了评论中。否则，SO会提示您在第7条或第8条评论之后移动聊天中的对话OK，这里的评论中是否应该有聊天链接？
