Question

我试图让弹弓工作但是很难过，我附上了我的代码。

我在控制台得到的错误是：

“提供调用'slingshot / uploadRequest'结果的异常：TypeError：无法读取未定义的属性'response'”

客户端

Template.hello.events({
    'change .uploadFile': function(event, template) {

      event.preventDefault();

var uploader = new Slingshot.Upload("myFileUploads");

uploader.send(document.getElementById('uploadFile').files[0], function (error, downloadUrl) {
  if (error) {
    // Log service detailed response
    console.error('Error uploading', uploader.xhr.response);
    alert (error);
  }
  else{
    console.log("Worked!");
  }

  });
}
});

LIB

Slingshot.fileRestrictions("myFileUploads", {
  allowedFileTypes: ["image/png", "image/jpeg", "image/gif"],
  maxSize: null // 10 MB (use null for unlimited)
});

服务器

Slingshot.fileRestrictions("myFileUploads", {
  allowedFileTypes: ["image/png", "image/jpeg", "image/gif"],
  maxSize: null,
});


    Slingshot.createDirective("myFileUploads", Slingshot.S3Storage, {
      AWSAccessKeyId: "my-AWSAccessKeyId",
      AWSSecretAccessKey: "my-AWSSecretAccessKey",
      bucket: "slingshot-trial-2",
      acl: "public-read",

      authorize: function () {
        //Deny uploads if user is not logged in.

        },
      key: function (file) {
        //Store file into a directory by the user's username.
        return file.name;
      }

    });

我看到同样的问题，原因是xhr为空 - 尝试删除引用它的控制台错误行，我假设您已开始看到带有实际错误的警报消息：

console.error('Error uploading', uploader.xhr.response);

我最后在引用它之前检查了xhr，然后记录它（如果存在的话）。

不能让Meteor弹弓上班
