Could not get the data in URL.createObjectURL-CodePudding

I am just curious about how to get the data wrapped in URL.createObjectURL.

So I write the following code.

function typedArrayToURL(typedArray, mimeType) {
  return URL.createObjectURL(new Blob([typedArray.buffer], {type: mimeType}))
}
const bytes = Uint8Array.from("https://www.baidu.com/")
// const url = typedArrayToURL(bytes, 'text/html');
const url = typedArrayToURL(bytes, 'text/plain; charset=utf-8');

let blob = await (await fetch(url)).blob();
console.info(new Uint8Array(blob))

let ab = await (await fetch(url)).arrayBuffer();
console.info(new Uint8Array(ab))

The size of blob or ab 22 which is eqauls to the length of "https://www.baidu.com/", but the data in it is all zero.

CodePudding user response：

An intArray expects integers. So you will have to provide the data in the correct format.

So something like

const bytes = Uint8Array.from("https://www.baidu.com/".split('').map(v=>v.charCodeAt(0)));

const encoder = new TextEncoder();
const bytes = Uint8Array.from(encoder.encode("https://www.baidu.com/"))
