sync-blob

利用 XHR 同方模式获取blob的内容，适合不能用异步方法的地方，比如getter,setter;

兼容性

• 利用 XHR 请求，所以 CSP 需要容许 blob: 请求
• 只适用于浏览器环境

Install

npm install sync-blob;

Demo

import syncBlob from "sync-blob";
const u8 = new Uint8Array([
  0, 1, 2, 3, 0x80, 0x90, 0xa0, 0xb0, 0xc0, 0xd0, 0xe0, 0xf0, 0xff,
]);
const blob = new Blob([u8], { type: "text/ini" });

console.log("blob2buffer:", syncBlob.blob2buffer(blob));
console.log("blob2String:", syncBlob.blob2String(blob, "Latin1")); // charset
console.log("blob2Base64:", syncBlob.blob2Base64(blob));

console.log(
  'btoa(blob2String(blob, "Latin1")):',
  btoa(syncBlob.blob2String(blob, "Latin1"))
);

API(Types)

 * Blob对像转为字符串
 * @param blob
 * @param charset 字符编码，默认取blob.type中的字符编码信息或utf-8
 * @returns
