無法解析包含Unicode十六進制字符的JSON字符串

Question

 var mystring = '{"Customers":[{"CustomerCity":"Zaragoza","CustomerFName":"Ana","CustomerAddress":"C/ El Temple, 9 2\\\\xbaB","CustomerCountry":"es"}]}'; var myparsestring = JSON.parse(mystring); 

錯誤：

JSON中的意外令牌x

Answer 1

那只是無效的JSON，請參閱json.org上的字符串規則。 JSON中沒有\\x轉義。 \\xbaB應該是Unicode轉義\஫ （請注意，必須正好有四個十六進制數字）：

 var mystring ='{"Customers":[{"CustomerCity":"Zaragoza","CustomerFName":"Ana","CustomerAddress":"C/ El Temple, 9 2\\\஫","CustomerCountry":"es"}]}'; var obj = JSON.parse(mystring); console.log(obj); 

您可以嘗試對字符串進行預處理：

mystring = mystring.replace(/\\x([0-9a-f]{1,4})/gi, function(m, c0) {
    return "\\u" + ("0000" + c0).slice(-4);
});

 var mystring ='{"Customers":[{"CustomerCity":"Zaragoza","CustomerFName":"Ana","CustomerAddress":"C/ El Temple, 9 2\\\\xbaB","CustomerCountry":"es"}]}'; // Fixing it mystring = mystring.replace(/\\\\x([0-9a-f]{1,4})/gi, function(m, c0) { return "\\\\u\u0026quot; + ("0000" + c0).slice(-4); }); var obj = JSON.parse(mystring); console.log(obj); 

...但實際上，修復JSON的源要好得多，這樣它才能生成有效的JSON，而以上內容是非常幼稚的修復。
