我正在尝试使用jQuery-File-Upload和aws-sdk gem以及遵循heroku’s direct to S3 upload指令直接在Rails中上传到Amazon S3.这是在html中生成的上传表单：
这是相应的jQuery：
$(function() {
$('.directUpload').find("input:file").each(function(i,elem) {
var fileInput = $(elem);
var form = $(fileInput.parents('form:first'));
var submitButton = form.find('input[type="submit"]');
var progressBar = $("Failed");
}
});
});
});
Started POST "/users/bazley/update_pictures" for ::1 at 2016-01-01 21:26:59 +0000 Processing by CharactersController#update_pictures as HTML
Parameters: {
"utf8"=>"✓","authenticity_token"=>"rvhu...fhdg==","standardpicture"=>{
"picture"=>#
表单提交成功,但它无法正常工作,因为Rails没有在S3上保存正确的位置(“图片”,字符串);相反,它认为位置是
"picture"=>#
您可以在提交的参数中看到这一点.它应该是这样的：
"picture"=>"//websmash.s3.amazonaws.com/uploads/220f5378-1e0f-4823-9527-3d1170089a49/europe.jpg"},"commit"=>"Upload pictures"}
我不明白的是,当表格中出现所有正确的信息时,为什么它会导致参数错误.它明确地说
data-url="https://websmash.s3.amazonaws.com"
在表单中,jQuery包括
url: form.data('url'),
出了什么问题？
为了完整性：在控制器中：
before_action :set_s3_direct_post
.
.
def set_s3_direct_post
@s3_direct_post = S3_BUCKET.presigned_post(key: "uploads/#{SecureRandom.uuid}/${filename}",success_action_status: '201',acl: 'public-read')
end
表格：
<%= form_for :standardpicture,url: update_pictures_user_path,html: { id: "pic-upload",class: "directUpload",data: { 'form-data' => (@s3_direct_post.fields),'url' => @s3_direct_post.url,'host' => URI.parse(@s3_direct_post.url).host }
} do |f| %>
aws.rb初始化器：
Aws.config.update({
region: 'us-east-1',credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'],ENV['AWS_SECRET_ACCESS_KEY']),})
S3_BUCKET = Aws::S3::Resource.new.bucket(ENV['S3_BUCKET'])
编辑
控制台显示此错误：
Uncaught TypeError: Cannot read property 'innerHTML' of null
在这个文件里面(tmpl.self-c210 … 9488.js？body = 1)：

}(this));
最佳答案
终于找到了答案here.只需要去application.js并进行更改
//= require jquery-fileupload
至
//= require jquery-fileupload/basic
基督在串联.在获得更多2个视图时,只有50个重复点.
