如何使用 JSON 查询将数组转换为字符串

Question

{
   "pull_request": {
     "patch_url": null,
   },
   "created_at": "2012-11-14T15:25:33Z",
   "comments": 0,
   "labels": [
     {
       "color": "ededed
     }
   ],
   "id": 8356941,
   "assignees": [
      {
        "login": "Paul",
        "id": 444
      },
      {
        "login": "Steve",
        "id": 222
       }
    ]

By JSON Query

assignees[*].login , getting below output.

["Paul","Steve"]

But required as comma separated string without quotes as below,

Paul, Steve

How to do this in JSON Query?

Answer 1

You can use JSON.stringify as below:

JS

 const obj = { "pull_request": { "patch_url": null, }, "created_at": "2012-11-14T15:25:33Z", "comments": 0, "labels": [{ "color": "ededed" }], "id": 8356941, "assignees": [{ "login": "Paul", "id": 444 }, { "login": "Steve", "id": 222 } ] } const myJSON = JSON.stringify(obj); console.log(myJSON);

If you would like to get comma seperated string for the array it can be done using join()

 const names = ["Paul","Steve"]; console.log(names.join(", "));

只要您的标题“如何将数组转换为字符串”是正确的，这将起作用：

assignees[*].login.toString()
