Meteor Amazon s3 删除图像

Question

我已经使用这个 meteor 包成功将图像上传到 amazon s3 https://github.com/Lepozepo/S3 现在我正在尝试删除文件，但出现错误。

这是 s3.delete 代码

的文档

S3.delete(path,callback)

This function permanently destroys a file located in your S3 bucket.

Parameters:

path: Must be in this format ("/folder/other_folder/file.extension"). So basically always start with "/" and never end with "/". This is required.

callback: A function that is run after the delete operation is complete returning an Error as the first parameter (if there is one), and a Result as the second.

这是我的上传删除代码

Template.postSubmit.events({
  "click button.upload": function(){
        var files = $("input.file_bag")[0].files

        S3.upload({
                files:files,
                path:"uploads"
            },function(e,r){
                console.log(r);

        delete_url = r.relative_url;

        console.log(delete_url);
        });
    },
  "click button.delete": function(){

    S3.delete({
      path:delete_url
      },function(e,r){
        console.log(e);
        console.log(r);
    });


    }
});

点击删除按钮时出现错误。

更新这是我在终端端的服务器上遇到的错误

Exception while invoking method '_s3_delete' Error: Match error: Expected string, got object

Answer 1

你应该这样称呼它：

S3.delete(delete_url, function() { ... });

第一个参数应该是 url 本身，而不是您示例中的对象。
