Question

How to convert array of file bytes [123, 10, 32, 32...] to bytearray?

(如何将文件字节数组[123, 10, 32, 32...] 123、10、32、32 [123, 10, 32, 32...]为bytearray？)

I have tried:

(我试过了：)

  static readFile(file) {
    let reader = new FileReader();

    console.log(file);

    reader.readAsText(file);

    reader.onload = function() {
      console.log(reader.result);
    };

    reader.onerror = function() {
      console.log(reader.error);
    };
  }

I get this error:

(我收到此错误：)

TypeError: Failed to execute 'readAsText' on 'FileReader': parameter 1 is not of type 'Blob'.

(TypeError：无法在'FileReader'上执行'readAsText'：参数1不是'Blob'类型。)
