未处理的PromiseRejectionWarning:ReferenceError:ReadableStream未定义

Question

我试图将文件的数组缓冲区转换为Typescript中的可读流，但当我试图创建一个新的ReadableStream变量时，我得到了以下错误：

UnhandledPromiseRejectionWarning: ReferenceError: ReadableStream is not defined

问题出在哪里？这是我的代码：

export function ReadableBufferStream(ab: ArrayBuffer) {
return new ReadableStream({
start(controller) {
controller.enqueue(ab)
controller.close()
}
})
}
export async function putFileToIPFS(file:ArrayBuffer): Promise<string>{
const readableStream = ReadableBufferStream(file)
let cid ;
try {
console.log("PRINT BEFORE PIN")
cid = await pinata.pinFileToIPFS(readableStream)
console.log(cid)
}   
catch (error) { console.error(error);}
return cid['IpfsHash']
}

有人知道怎么帮我吗？我从一个缓冲区数组开始，希望能够获得ReadableStream，以便能够在IPFS上加载它。感谢

你能试试这个吗(从node类型导入ReadableStream(。。。

import { ReadableStream } from 'node:stream/web';

import { ReadableStream } from 'node:stream/web'; // <-- Put this in the beginning of the code file
// ....

export function ReadableBufferStream(ab: ArrayBuffer) {
return new ReadableStream({
start(controller) {
controller.enqueue(ab)
controller.close()
}
})
}
export async function putFileToIPFS(file:ArrayBuffer): Promise<string>{
const readableStream = ReadableBufferStream(file)
let cid ;
try {
console.log("PRINT BEFORE PIN")
cid = await pinata.pinFileToIPFS(readableStream)
console.log(cid)
}   
catch (error) { console.error(error);}
return cid['IpfsHash']
}
