只是把 send 的数据从 JSON 换成 FormData or URLSearchParams 就可以了。 另外,FormData or FormUrlEncoded 不需要设置 request header 'Content-Type',游览器会依据发送的数据类型自动添加,JSON 之所以需要是因为游览器把 JSON 视为 text/plain。 POST Binary (Blob) FormData 支持 Blob 类型的 value,所以我们可以...
import { fetch } from '@adobe/fetch'; const url = 'https://httpbin.org/cache/60'; // -> max-age=60 (seconds) // send initial request, priming cache let resp = await fetch(url); assert(resp.ok); assert(!resp.fromCache); // re-send request and verify it's served from cache...
代码语言:txt 复制 app.post('/upload', upload.single('blobData'), (req, res) => { const blobData = req.file.buffer; // 获取blob数据 // 处理接收到的blob数据 res.send('Blob data received successfully'); }); 启动服务器并监听指定的端口: 代码语言:txt 复制 const port = 3000; ...

这个方法会返回一个在 resolved 后会成为 ArrayBuffer 的 Promise。我们可以用它来解析二进制数据,然后用 ArrayBuffer 来创建 typed array 或者 DataView 对象。 blob() 这个方法会返回一个在 resolved 后会成为 Blob 对象的 Promise。Blob(Binary Large Object)通常会用于处理许多二进制数据。如果我们想要将响应体转换...

To send binary data, you have two choices, use BASE64 encoded string or path points to a file contains the body. If the Content-Type containing substring;BASE64 or application/octet the given body will be considered as a BASE64 encoded data which will be decoded to binary data as the re...
