javascript - 如何解析在javascript中嵌套了转义JSON的JSON？

Question

更新：这个 JSON 只是示例之一，我需要读取这些 JSON 文件并将它们传递给接受 JSONObject 的函数。

我有一个这样的 JSON -

    {   "log": {
    "version": "1.2",
    "entries": [
      {
        "response": {
          "status": 200,
          "statusText": "OK",
          "httpVersion": "HTTP/1.1",
          "headers": [
            {
              "name": "Date",
              "value": "Tue, 19 Feb 2019 13:50:34 GMT"
            },
            {
              "name": "CF-RAY",
              "value": "4ab934095ceacc4c-ZRH"
            },
            {
              "name": "Content-Encoding",
              "value": "gzip"
            }
          ],
          "cookies": [],
          "content": {
            "size": 155,
            "mimeType": "application/json",
            "compression": 0,
            "text": "{\"ip\":\"45.64.195.115\",\"ip_decimal\":759219059,\"country\":\"India\",\"country_eu\":false,\"country_iso\":\"IN\",\"city\":\"nocity\",\"latitude\":98.975,\"longitude\":92.8258}"
          },
          "redirectURL": "",
          "headersSize": 230,
          "bodySize": 155,
          "_transferSize": 385
        },
        "cache": {},
        "timings": {
          "blocked": 6.805000007039867,
          "dns": -1,
          "ssl": -1,
          "connect": -1,
          "send": 0.22000000000000064,
          "wait": 174.87700000413787,
          "receive": 11.549999995622784,
          "_blocked_queueing": 0.8590000070398673
        },
        "serverIPAddress": "100.28.12.103",
        "_initiator": {
          "type": "other"
        },
        "_priority": "VeryHigh",
        "connection": "509100",
        "pageref": "page_2"
      }
    ]   
  } 
}

我正在尝试解析正在使用-

var parsed = JSON.parse(myJson);

这会在这部分引发错误 -"text": "{\"ip\":\"49.64.194.115\",\"ip_decimal\":75

因为它是一个转义的嵌套 JSON。

我该怎么做？我在这里找到了一种方法，但不适用于此问题。

您的 json 已经可以用作 javascript 对象

const myJSON = {
   "log":{
      "version":"1.2",
      "entries":[
         {
            "response":{
               "status":200,
               "statusText":"OK",
               "httpVersion":"HTTP/1.1",
               "headers":[
                  {
                     "name":"Date",
                     "value":"Tue, 19 Feb 2019 13:50:34 GMT"
                  },
                  {
                     "name":"CF-RAY",
                     "value":"4ab934095ceacc4c-ZRH"
                  },
                  {
                     "name":"Content-Encoding",
                     "value":"gzip"
                  }
               ],
               "cookies":[

               ],
               "content":{
                  "size":155,
                  "mimeType":"application/json",
                  "compression":0,
                  "text":"{\"ip\":\"45.64.195.115\",\"ip_decimal\":759219059,\"country\":\"India\",\"country_eu\":false,\"country_iso\":\"IN\",\"city\":\"nocity\",\"latitude\":98.975,\"longitude\":92.8258}"
               },
               "redirectURL":"",
               "headersSize":230,
               "bodySize":155,
               "_transferSize":385
            },
            "cache":{

            },
            "timings":{
               "blocked":6.805000007039867,
               "dns":-1,
               "ssl":-1,
               "connect":-1,
               "send":0.22000000000000064,
               "wait":174.87700000413787,
               "receive":11.549999995622784,
               "_blocked_queueing":0.8590000070398673
            },
            "serverIPAddress":"100.28.12.103",
            "_initiator":{
               "type":"other"
            },
            "_priority":"VeryHigh",
            "connection":"509100",
            "pageref":"page_2"
         }
      ]
   }
}

如果你想解析 'log.entries.response.content.text' 你可以做这样的事情

if (myJSON.log && myJSON.log.entries && myJSON.log.entries.length > 0) {
  for (const element of myJSON.log.entries) {
    if (element.response && element.response.content && element.response.content.text) {
      try {
        element.response.content.text = JSON.parse(element.response.content.text);
      } catch (error) {
        console.log('do nothing')
      }
    }
  }
}
