NodeJS从base64提供图像

Question

I have a Route on my Meteor App:

    this.route("/userimg/:id", function(){
        console.log("hello");
        img_base64 = Meteor.users.findOne(this.params.id).userimage;
        this.response.writeHead(200, {'Content-Type': 'image/png' });

    },{where: 'server'});

With this Route I want to serve Userimages from my Mongo-Collection. I have a base64 encoded image in my Collection and saving it to varibale img_base64 . My Question is, what do I need to do with my base64 variable to respond it as a png? I need somthing like this.response.end(img_base64,....) . Thanks for your help!

Answer 1

这实际上就是您所需要的（假设img_base64是一个字符串）：

this.response.end(img_base64, 'base64');
