{{APIRef("Fetch")}}


{{domxref("Response")}}  接口的status 只读属性包含响应的状态代码（例如，成功为200）。

语法

let myStatus = response.status;

值

一个数字（确切来讲是一个unsigned short）

示例

In our Fetch Response example (see Fetch Response live) we create a new {{domxref("Request")}} object using the {{domxref("Request.Request","Request()")}} constructor, passing it a JPG path. We then fetch this request using {{domxref("GlobalFetch.fetch","fetch()")}}, extract a blob from the response using {{domxref("Body.blob")}}, create an object URL out of it using {{domxref("URL.createObjectURL")}}, and display this in an {{htmlelement("img")}}.

Note that at the top of the fetch() block we log the response status value to the console.

var myImage = document.querySelector('img');

var myRequest = new Request('flowers.jpg');

fetch(myRequest).then(function(response) {
  console.log(response.status); // returns 200
  response.blob().then(function(myBlob) {
    var objectURL = URL.createObjectURL(myBlob);
    myImage.src = objectURL;
  });
});
