{{ APIRef("Fetch") }}
- -

The Body {{glossary("mixin")}} of the Fetch API represents the body of the response/request, allowing you to declare what its content type is and how it should be handled.

- -

Body is implemented by both {{domxref("Request")}} and {{domxref("Response")}}. This provides these objects with an associated body (a stream), a used flag (initially unset), and a MIME type (initially the empty byte sequence).

- -

Properties

- -
-
{{domxref("Body.body")}} {{readonlyInline}}
-
A simple getter used to expose a {{domxref("ReadableStream")}} of the body contents.
-
{{domxref("Body.bodyUsed")}} {{readonlyInline}}
-
A {{domxref("Boolean")}} that indicates whether the body has been read.
-
- -

Methods

- -
-
{{domxref("Body.arrayBuffer()")}}
-
Takes a {{domxref("Response")}} stream and reads it to completion. It returns a promise that resolves with an {{domxref("ArrayBuffer")}}.
-
{{domxref("Body.blob()")}}
-
Takes a {{domxref("Response")}} stream and reads it to completion. It returns a promise that resolves with a {{domxref("Blob")}}.
-
{{domxref("Body.formData()")}}
-
Takes a {{domxref("Response")}} stream and reads it to completion. It returns a promise that resolves with a {{domxref("FormData")}} object.
-
{{domxref("Body.json()")}}
-
Takes a {{domxref("Response")}} stream and reads it to completion. It returns a promise that resolves with the result of parsing the body text as {{jsxref("JSON")}}.
-
{{domxref("Body.text()")}}
-
Takes a {{domxref("Response")}} stream and reads it to completion. It returns a promise that resolves with a {{domxref("USVString")}} (text). The response is always decoded using UTF-8.
-
- -

Examples

- -

The example below uses a simple fetch call to grab an image and display it in an {{htmlelement("img")}} tag. You'll notice that since we are requesting an image, we need to run {{domxref("Body.blob","Body.blob()")}} ({{domxref("Response")}} implements body) to give the response its correct MIME type.

- -

HTML Content

- -
<img class="my-image" src="https://wikipedia.org/static/images/project-logos/frwiki-1.5x.png">
-
- -

JS Content

- -
var myImage = document.querySelector('.my-image');
-fetch('https://upload.wikimedia.org/wikipedia/commons/7/77/Delete_key1.jpg')
-	.then(res => res.blob())
-	.then(res => {
-		var objectURL = URL.createObjectURL(res);
-		myImage.src = objectURL;
-});

{{domxref("Body")}} mixin 的 json() 會拿 {{domxref("Response")}} stream 並完整地讀取他。它會回傳一個能夠實現 (resolve) 把回傳的結果的 body text 解析成 {{jsxref("JSON")}} 型別的 Promise。

- -

語法

- -
response.json().then(function(data) {
-  // do something with your data
-});
- -

參數

- -

None.

- -

回傳

- -

一個能夠實現 (resolve) 把回傳的結果的 body text 解析成 JSON 型別的 Promise。這可以是任何能夠被 JSON 呈現的資料型別 — 物件 (object), 陣列 (array), 字串 (string), 數字 (number)...

- -

範例

- -

在我們的範例 fetch json example (run fetch json live) 中，我們用 constructor {{domxref("Request.Request")}} 產生一個新的請求，並且用它去取回 .json 檔案。 當成功取回 (fetch) 時，我們使用 json() 去讀取跟解析資料，然後依照我們期待的把回傳的結果物件 (resulting objects) 裡讀取到的數值存入 list 中藉以顯示我們的產品資料。

- -
var myList = document.querySelector('ul');
-
-var myRequest = new Request('products.json');
-
-fetch(myRequest)
-  .then(function(response) { return response.json(); })
-  .then(function(data) {
-    for (var i = 0; i < data.products.length; i++) {
-      var listItem = document.createElement('li');
-      listItem.innerHTML = '<strong>' + data.products[i].Name + '</strong> can be found in ' +
-                           data.products[i].Location +
-                           '. Cost: <strong>£' + data.products[i].Price + '</strong>';
-      myList.appendChild(listItem);
-    }
-  });
