Question

我有一个简单的Sinatra应用程序。一个端点用于页面，包括用d3.js呈现的图表。 d3使用对d3.json的调用从第二个端点“\ tasks.json”加载数据。

  d3.json('/tasks.json', function(json) { ... }

这适用于我的Windows PC，但是当推送到生产（linux盒子）时，我没有显示数据。使用chrome查看网络流量，我可以看到“tasks.json”调用失败，并显示以下标题：

HTTP/1.0 403 Forbidden
Server: openresty

X-Cache-Lookup: MISS from proxy.xx.xx.xx:3128

然而....如果我直接在浏览器中打开相同的'tasks.json'端点，它就可以正常加载。

HTTP/1.0 200 OK

在我的sinatra应用程序中，我也关闭了保护。

  set :protection, false

有什么想法？

注意：如果用jquery ajax调用替换d3.json调用，则它开始工作。因此，我认为d3必须在它的请求中设置一个属性，即Sinatra / Rack管道阻塞了403.

有没有办法弄清楚堆栈的哪个部分正在返回403？

我正在将服务器作为docker容器运行，docker日志显示请求进入但不解释403.

Answer 1

我不明白为什么会这样，但最后我做了以下事情。

  get '/:file.json' do |file|
    #content_type :json
    content_type  = 'text/json'
    File.read("#{file}.json")
  end

我更改了“content_type”行，将内容设置为“text / json”。这允许D3库正确加载数据。

我认为这相当于它上面的一行。

使用d3.json查询sinatra应用程序在localhost上工作正常，但在部署时失败并禁用
