针对Javascript Blob的Ruby rest-client API请求

Question

我正在尝试在Ruby中为此页面中触发的API请求创建一个rest-client请求.(来源)

通过查看页面中的Javascript,我注意到有一个Javascript Blob被创建并且JSON内容被附加到那个,然后以多部分形式提交,并带有以下脚本 -

我尝试使用以下代码用ruby中的rest-client gem模拟这个 -

namespace :materialize do
  task :connect => :environment do
    base_uri = "https://imatsandbox.materialise.net/web-api/cartitems/register"
    request = '{
     "cartItems":[
     {
       "toolID":"d65e1eca-7adf-453d-a3bb-eb051fffb567",
       "MyCartItemReference":"some reference",
       "modelID":"62352bab-d490-410c-851d-bc62e056e82a",
       "modelFileName":"",
       "fileUnits":"mm",
       "fileScaleFactor":"1",
       "materialID":"035f4772-da8a-400b-8be4-2dd344b28ddb",
       "finishID":"bba2bebb-8895-4049-aeb0-ab651cee2597",
       "quantity":"1",
       "xDimMm":"12",
       "yDimMm":"159.94",
       "zDimMm":"12",
       "volumeCm3":"2.0",
       "surfaceCm2":"100.0",
       "iMatAPIPrice": "25.0",
       "mySalesPrice": "26.0",
     }
     ],
     "currency":"EUR"
  }'
File.open('request', 'wb') do |f|
    f.write request
end


  response = RestClient.post base_uri, {:data => request, headers: {:multipart => true, accept: :json}}
  puts response.request
 end
end

我总是得到的反应机构 -

"{\"error\":{\"message\":\"Wrong request body. Check if all parameters set correctly\",\"code\":401},\"cartItems\":[]}"

我究竟做错了什么？

Answer 1

您收到 401，这意味着您的请求未获授权。我认为您需要通过您的请求传递凭据。查看页面底部有关将注册电子邮件地址传递到演示 api 的注释： https: //imatsandbox.materialise.net/api/demo/

看起来你需要这样做：
