问题描述

我正在尝试使用此模块 https://www.npmjs.com/package/s3-uploader ，但对我来说，如何实现它尚不清楚.如何对路由器执行 POST ?

I am trying to use this module https://www.npmjs.com/package/s3-uploader but for me it's not clear how to implement it. How to do a POST to my router ?

.post('/upload', ensureAuthenticated, (req, res, next) => {

let files = req.files;

let client = new Upload(process.env.AWS_BUCKET_NAME, {
  aws: {
    path: process.env.AWS_BUCKET_PATH,
    region: process.env.AWS_BUCKET_REGION,
    acl: 'public-read'
  },

  cleanup: {
    versions: true,
    original: false
  },

  original: {
    awsImageAcl: 'private'
  },

  versions: [{
    maxHeight: 1040,
    maxWidth: 1040,
    format: 'jpg',
    suffix: '-large',
    quality: 80,
    awsImageExpires: 31536000,
    awsImageMaxAge: 31536000
  },{
    maxWidth: 780,
    aspect: '3:2!h',
    suffix: '-medium'
  },{
    maxWidth: 320,
    aspect: '16:9!h',
    suffix: '-small'
  },{
    maxHeight: 100,
    aspect: '1:1',
    format: 'png',
    suffix: '-thumb1'
  },{
    maxHeight: 250,
    maxWidth: 250,
    aspect: '1:1',
    suffix: '-thumb2'
  }]
});

client.upload(files.file.path, {}, function(err, versions, meta) {
  if (err) { throw err; }

  versions.forEach(function(image) {
    console.log(image.width, image.height, image.url);
    // 1024 760 https://my-bucket.s3.amazonaws.com/path/110ec58a-a0f2-4ac4-8393-c866d813b8d1.jpg
  });
});
}

在 .post 内的

我复制并粘贴了他们在NPM网站中拥有的代码，并将变量值更改为我的值.

inside the .post I copied and paste the code they have in NPM website and changed the variables values to mine values.

我收到此错误:

Error: Command failed: identify -format "name=

我在此线程中找到了一个相关但不完全有用的主题: Node.js S3-uploader问题

I found a related but not fully helpful topic in this thread: Node.js S3-uploader issue

推荐答案

以下是解决方案:

我唯一要做的就是在本地主机上安装imagemagick.

The only thing that I did was installing imagemagick on my localhost.

您必须在终端中运行它.

You have to run this in your terminal.

cd $ HOME

酿造imagemagick

完成后，您可以运行它以查看版本和详细信息

When it finish you can run this to see the version and details

brew info imagemagick

如果您没有酿酒，则需要安装它.

If you dont have brew then you need to install it.

谢谢
