[英]parsing a JSON string response. Already tried JSON.parse()
我有一個看起來像這樣的響應對象-
{
location: '{country:Poland,latitude:50.0575,longitude:19.9802}',
ip: '83.26.234.177',
name: 'John Doe'
}
我正在嘗試讀取這樣的國家/地區名稱-
data.forEach(function(datapoint) {
dataObject.ip = datapoint.ip;
var locationObject = datapoint.location; // also tried JSON.parse
console.log(locationObject); //{country:Poland,latitude:50.0575,longitude:19.9802}
console.log(locationObject.country); // undefined
console.log(locationObject.latitude); //undefined
console.log(locationObject.longitude); //undefined
}
變得undefined
。
datapoint.location
是無效的json。 使用String#replace將其轉換為有效的json字符串,然后進行解析:
var data = [{ location: '{country:Poland,latitude:50.0575,longitude:19.9802}', ip: '83.26.234.177', name: 'John Doe' }]; data.forEach(function(datapoint) { var json = datapoint.location.replace(/([^\\d\\.{}:,]+)/g, '"$1"'); // wrap the keys and non number values in quotes var locationObject = JSON.parse(json); console.log(locationObject.country); console.log(locationObject.latitude); console.log(locationObject.longitude); });
location
屬性中的值是無效的JSON。 JSON.parse
失敗。 您將需要以下內容:
'{"country":"Poland","latitude":50.0575,"longitude":19.9802}'
請注意,屬性和字符串值如何用"
括起來。
