我正在为第 3 方 API 尝试多重导入功能，我需要在其中传递一个 json 文件读取流。

但我的 api 中已经有一组用户数据，我需要将其作为读取流传递。

我已经尝试过的选项。

1. fs.createReadStream

fs.createReadStream(Buffer.from(JSON.stringify('[{ user: "data"}]')));

createReadStream not accepting Buffer & returns

ENOENT: no such file or directory, open

1. require('stream').Readable

   const Readable = require('stream').Readable; const readStream = new Readable(); readStream._read = () => {}; readStream.push(JSON.stringify(u)); readStream.push(null);

Read stream gives me "Invalid multipart payload format" error in my request

请找到我为多用户文件上传传递的请求对象

{
  "url": "",
  "method": "POST",
  "headers": {},
  "formData": {
    "userFile": ReadStream
  }
}

如有任何建议，我们将不胜感激

最佳答案

您可以像这样从字符串创建可读流:

import { Readable } from 'stream';
// OR: const { Readable } = require('stream');

const stream = Readable.from("This is the stream content");
