Deno.readall

readAll

• readAll(r: Reader): Promise<Uint8Array>

• • 定义在 lib.deno.ns.d.ts:1169

  读取 Reader r 直到文件的末尾 (Deno.EOF)，返回文件的内容，以 Uint8Array 表示。

  Read Reader r until end of file (Deno.EOF) and resolve to the content as Uint8Array.

    // Example：从 stdin 读取
    const stdinContent = await Deno.readAll(Deno.stdin);
  

    // Example：从文件读取
    const file = await Deno.open("my_file.txt", {read: true});
    const myFileContent = await Deno.readAll(file);
    Deno.close(file.rid);
  

    // Example：从 buffer 读取
    const myData = new Uint8Array(100);
    // ... 此处省略了填充 myData 数组的代码
    const reader = new Deno.Buffer(myData.buffer as ArrayBuffer);
    const bufferContent = await Deno.readAll(reader);
