Javascript如何解析服务器响应

  • 772

请告诉我如何使用 Js 进行解析，这是请求的示例吗？（通常我解析没有标题的响应）。服务器响应示例：

HTTP/1.1 400 Bad Request
content-length: 97
content-type: application/json; charset=utf-8
Date: Tue, 02 Nov 2021 16:47:29 GMT
Connection: keep-alive
Keep-Alive: timeout=5

{"statusCode":400,"error":"Bad Request","message":"body should have required property 'user_id'"}

我将永远只需要获得价值statusCode

PS忽略错误

    我不知道为什么答案是这样的。这是不对的。但如果有必要，你可以试试这个：

    let text = `HTTP/1.1 400 Bad Request
content-length: 97
content-type: application/json; charset=utf-8
Date: Tue, 02 Nov 2021 16:47:29 GMT
Connection: keep-alive
Keep-Alive: timeout=5

{"statusCode":400,"error":"Bad Request","message":"body should have required property 'user_id'"}`;

let json = JSON.parse(text.substr(text.indexOf('{')));
console.log(json.statusCode);

    使用正则表达式：

    let text = `HTTP/1.1 400 Bad Request
content-length: 97
content-type: application/json; charset=utf-8
Date: Tue, 02 Nov 2021 16:47:29 GMT
Connection: keep-alive
Keep-Alive: timeout=5

{"statusCode":400,"error":"Bad Request","message":"body should have required property 'user_id'"}`;

var regex = /{.*?}/g;
var json = JSON.parse(regex.exec(text));
console.log(json.statusCode);
