解析 HttpClientRequest 响应

Question

我还有一个新手（可能是愚蠢的）问题。我正在使用 HttpClientRequest 并拨打电话。我也有回复。

var url = <my url>
var request = new HttpClientRequest(url);
request.header["Content-Type"] = "application/x-www-form-urlencoded";
request.method = "POST";

try
{

  request.execute();
  var rawResponse = request.response.body.toString();
}

服务器的响应格式如下： {"token":"abc","expires_in":9292,"refresh":"deeDfTTgendj"}

我只需要从响应中提取“expires_in”和“refresh”字段

既然是有效的 JSON，你可以解析它：

var rawResponse = request.response.body.toString(),
    objectLiteral = JSON.parse(rawResponse);

var expires_in = objectLiteral['expires_in'],
    refresh = objectLiteral['refresh'];

var rawResponse = '{"token":"abc","expires_in":9292,"refresh":"deeDfTTgendj"}';
    objectLiteral = JSON.parse(rawResponse);

var expires_in = objectLiteral['expires_in'],
    refresh = objectLiteral['refresh'];

console.log(expires_in, refresh);

注意：查看browser support 以获得JSON.parse()
