Uncaught SyntaxError: Unexpected token c in JSON at position 13

Question

我有一个字符串 (var)，我在 javascript 中解析为 JSON。但是一旦我这样做，我就会收到一条错误消息

Uncaught SyntaxError: Unexpected token c in JSON at position 13

var DL_response = {"result":"{"cov_details":[{"issue_date":"UNIT 
 OFFICE,NEYVELI","cov":"MCWG"}],"dl_number":"TN39Y20100000784","address":"PERIYA COLONY  KO PAVAZHANGUDI  
 VIRUDHACHALAM TK","issue_date":"24-03-2020","dob":"21-03-1971","name":"VICNESWARAN 
 S","blood_group":"","validity":{"transport":"","non-transport":"24-03-2010 to 23-03- 
 2030"},"father_husband":"SELVARAJ"}","status-code":"101","request_id":"a9642ae9-2f10-4e9a-9f7e- 
 c3ee1a9a2dbe"}
var Driving_License = JSON.parse(DL_response);

可能导致此错误的原因是什么？是因为有什么特殊字符吗？

Answer 1

首先，您的JSON是无效的。其次，它不是 JSON 字符串，而是 JavaScript 对象本身。没有必要再次解析它。如果对象有效，您可以直接访问它而无需进一步解析。

这是我修正的数据。

var DL_response = {
   "result":{
      "cov_details":[
         {
            "issue_date":"UNIT OFFICE,NEYVELI",
            "cov":"MCWG"
         }
      ],
      "dl_number":"TN39Y20100000784",
      "address":"PERIYA COLONY KO PAVAZHANGUDI  VIRUDHACHALAM TK",
      "issue_date":"24-03-2020",
      "dob":"21-03-1971",
      "name":"VICNESWARANS",
      "blood_group":"",
      "validity":{
         "transport":"",
         "non-transport":"24-03-2010 to 23-03-2030"
      },
      "father_husband":"SELVARAJ",
      "status-code":"101",
      "request_id":"a9642ae9-2f10-4e9a-9f7e-c3ee1a9a2dbe"
   }
}

console.log(DL_response.result.dob)
// output: 21-03-1971
