Question

我正在尝试设置CollectionFS和S3，以便我可以从AutoForm上传文件到S3。

我有一个生成在服务器上的.allow函数定义的Image FS.Collection，如下所示：

// Client and server.
var imageStore = new FS.Store.S3('images', {                                                                            
  region: 'us-east-1',                                                                                                  
  accessKeyId: 'mykey',                                                                                                                                            
  secretAccessKey: 'my/key',                                                          
  bucket: 'buketz',                                                                                               
  folder: 'images',                                                                                                     
});                                                                                                                     

Images = new FS.Collection('images', {                                                                                  
  stores: [imageStore],                                                                                                 
  filter: {                                                                                                             
    allow: {                                                                                                            
      contentTypes: ['image/*'],                                                                                        
      extensions: ['png', 'PNG', 'jpg', 'JPG', 'jpeg', 'JPEG']                                                          
    }                                                                                                                   
  }                                                                                                                     
});

// Server only.
Images.allow({                                                                                                                                                                    
  insert: function (userId, image) {                                                                                    
    return true;                                                                                                        
  },                                                                                                                    
  update: function (userId, image) {                                                                                    
    return true;                                                                                                        
  },                                                                                                                    
  remove: function (userId, image) {                                                                                    
    return true;                                                                                                        
  },                                                                                                                    
  download: function (userId, image) {                                                                                  
    return true;                                                                                                        
  }                                                                                                                     
});

现在，当我加载应用程序时，Meteor会抛出这个错误：

/Users/pcoffey/.meteor/packages/cfs_s3/.0.1.3.1ba5bia++os+web.browser+web.cordova/npm/node_modules/aws-sdk/lib/request.js:32

将FS.debug设置为true会返回此错误：

如果我更改了集合名称，它会暂时加载，但是一旦我尝试上传文件，错误就会再次启动。有没有人知道可能导致这个问题的原因？

Answer 1

听起来像是AWS权限的问题。你做过setup吗？

Answer 2

我得到了这样的设置，对我来说效果非常好。我使用以下包：

$( "#gender" ).val();
"Female"

//客户端代码

 cfs:standard-packages
 cfs:filesystem
 cfs:s3
 cfs:graphicsmagick

//服务器端代码

var companyLogoStore = new FS.Store.S3( "companyLogo" );
Images = new FS.Collection( "images", {
  stores: [ companyLogoStore ],
  filter: {
    maxSize: 5242880, // in bytes
    allow: {
        contentTypes: [ 'image/*' ],
        extensions: [ 'png', 'bmp', 'jpeg', 'gif', 'webp', 'jpg' ]
    }
  },
  onInvalid: function ( message ) {
    if ( Meteor.isClient ) {
        Alerts.add( message, 'danger' );
    } else {
        console.log( message );
    }
  }
} );

我也使用ongoworks：权限安全包

 var companyLogoStore = new FS.Store.S3("companyLogo", {
  region: "xxxxxx", 
  accessKeyId: "xxxxxxx",
  secretAccessKey: "xxxxxxxx",
  bucket: "xxxxxxx",
  ACL: "public-read", **//optional, default is 'private', but you can allow public or secure access routed through your app URL**
  fileKeyMaker: function (fileObj) {
    return 'uploads/company/' + fileObj.original.name;
  },
  transformWrite: function(fileObj, readStream, writeStream) {
    gm(readStream, fileObj.name()).resize('210', '210').stream().pipe(writeStream);
  },
  maxTries: 3 //optional, default 5
 });
