Response() 构造函数创建新 响应 对象。

句法

var myResponse = new Response(body, init);
					

参数

body 可选

An object defining a body for the response. This can be null (which is the default value), or one of:

• Blob
• BufferSource
• FormData
• ReadableStream
• URLSearchParams
• USVString

init 可选

An options object containing any custom settings that you want to apply to the response, or an empty object (which is the default value). The possible options are:

• status : The status code for the reponse, e.g., 200 .
• statusText : The status message associated with the status code, e.g., OK .
• headers : Any headers you want to add to your response, contained within a 头 object or object literal of ByteString key/value pairs (see HTTP headers for a reference).

范例

In our Fetch Response example (见 Fetch Response live ) we create a new 响应 object using the constructor, passing it a new Blob as a body, and an init object containing a custom status and statusText :

var myBlob = new Blob();
var init = { "status" : 200 , "statusText" : "SuperSmashingGreat!" };
var myResponse = new Response(myBlob,init);
