如何将json转换为javascript对象？

Question

I have a JSON which contains directory structure and needs to convert to javascript object so that a map for key-value pair can be formed from it.

{
    "/Inbound/tmp/ARTIFACTDOWNLOAD_DIR": [
        {
            "filePath": "/Inbound/tmp/ARTIFACTDOWNLOAD_DIR",
            "fileName": "package_installation_logs.txt",
            "lastModifiedDate": "06-14-2019 09:34:43",
            "sizeofFile": "0 KB",
            "type": "File"
        }
    ],
    "/Inbound": [
        {
            "filePath": "/Inbound",
            "fileName": "osqueryd.INFO",
            "lastModifiedDate": "06-14-2019 09:23:26",
            "sizeofFile": "1 KB",
            "type": "File"
        },
        {
            "filePath": "/Inbound",
            "fileName": "tmp",
            "lastModifiedDate": "06-14-2019 10:51:55",
            "sizeofFile": "",
            "type": "Folder"
        }
    ]
}

Here key-value pairs in JSON contain different keys. So, how I can map key-value to javascript object using typescript

Answer 1

Simply use it like this

 // your JSON - compressed const json = '{"/Inbound/tmp/ARTIFACTDOWNLOAD_DIR":[{"filePath":"/Inbound/tmp/ARTIFACTDOWNLOAD_DIR","fileName":"package_installation_logs.txt","lastModifiedDate":"06-14-2019 09:34:43","sizeofFile":"0 KB","type":"File"}],"/Inbound":[{"filePath":"/Inbound","fileName":"osqueryd.INFO","lastModifiedDate":"06-14-2019 09:23:26","sizeofFile":"1 KB","type":"File"},{"filePath":"/Inbound","fileName":"tmp","lastModifiedDate":"06-14-2019 10:51:55","sizeofFile":"","type":"Folder"}]}' const objFromJson = JSON.parse(json) // the whole object console.log(objFromJson) console.log(objFromJson['/Inbound/tmp/ARTIFACTDOWNLOAD_DIR']) // the elements one by one for (let key in objFromJson) { objFromJson[key].forEach(item => { console.log(item) }) }

Use JSON parser.

var obj = JSON.parse('{ "name":"John", "age":30, "city":"New York"}');
