如何使用 express 将 blob url 图像保存在文件夹中？

Question

您好，我在请求中有此输入

{
  "title": "Places Search Box",
  "tags": "sd",
  "pictures": {
    "rawFile": {
      "path": "Screenshot 2020-03-05 at 12.05.55 PM.png"
    },
    "banner": "blob:http://localhost:3001/3b3dead6-bee0-4a9c-a0b3-28a560ee1558"
  }
}

如何使用 node.js 将此 blob URL blob:http://localhost:3001/3b3dead6-bee0-4a9c-a0b3-28a560ee1558 图像保存在文件夹中。

当我试图像这样保存时

const fs = require('fs');
const myUrl = res.pictures.banner;


fs.writeFile("/myFolder/myFile", myUrl, function(err) {
    if(err) {
        return console.log(err);
    }
    console.log("The file was saved!");
}); 

那么's 看起来像这样

const fs = require('fs');

const res = {
  "title": "Places Search Box",
  "tags": "sd",
  "pictures": {
    "rawFile": {
      "path": "Screenshot 2020-03-05 at 12.05.55 PM.png"
    },
    "banner": "blob:http://localhost:3001/3b3dead6-bee0-4a9c-a0b3-28a560ee1558"
  }
}

const myUrl = res.pictures.banner;


fs.writeFile("/myFolder/myFile", myUrl, function(err) {
    if(err) {
        return console.log(err);
    }
    console.log("The file was saved!");
}); 

这很简单，如果您不明白，请询问您错过了什么。
