Question

您好我能成功发布Post man，但无法从Ruby Rest客户端发帖。

发帖人请求

POST /endpoint HTTP/1.1
Host: host:11400
Accept: application/json
HTTP_USER: userid
fname: fname
lname: lname
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 589a5345-e384-bd71-d690-60987165487b

{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}

其余的代码我试过多种方式，包括下面的

尝试了

方法

p RestClient.post 'http://url_details',
                  Accept: 'application/json',
                  'HTTP_USER'.to_sym => 'userid',
                  fname: 'name',
                  lname: '',
                  'Content-Type'.to_sym => 'application/json',
                  payload: JSON.parse('{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}')

尝试了

方法

p RestClient.post 'http://url_details/job', http_user:  'userid', content_type: :json, accept: :json

尝试了

方法

p @uber_ride = (RestClient::Request.execute(
    :method => :post,
    :url => 'http://url_details/job',
    'HTTP_USER' => 'userid',
    :headers => {:content_type => 'application/json', :accept => 'application/json', :HTTP_USER => 'userid', :fname => 'name', :lname => 'lname'}
))

尝试了

方法

p '++++++++++++++++++++++++++++++++'
p RestClient.post($Current_Api_Endpoint,
                  $Current_Payload,
                  :http_user =>'userid',
                  headers:
                      {:accept => 'application/json',
                       :content_type => 'application/json',
                       :http_user =>'userid',
                       :fname => 'name',
                       :lname => 'lname'}
                )


p '++++++++++++++++++++++++++++++++'

尝试了

方法

p env1 = ENV['http_proxy']
# p a = {:method => :post, :url => 'http://url_details/job', :headers => { :accept => 'application/json', :content_type => 'application/json', :http_user => 'userid', :fname => 'name', :lname => 'lname' }, :payload => { :rtdt => "06/10/2016",:jobs => [{:pid => 53} , {:pid => 54}]} }
p a = {
        method: 'post',
        url: 'http://url_details/job',
        proxy: ENV['http_proxy'],
        headers: {accept: 'application/json', content_type: 'application/json', http_user: 'userid', fname: 'name', lname: 'lname'},
        payload: { rtdt: '06/10/2016', jobs: {pid: 53}}

      }

我收到错误 HTTP状态500 - 在请求中找不到HTTP_USER标头 torg.springframework.security.web.authentication

从那以后我发现了这个问题。除了这一个之外，所有标题都可以发送 - 这个标题在CAPS中。其余的人都是小角色。如何解决

Answer 1

Ruby的Net::HTTP实现不会传输ALL_CAPS_UNDERSCORED标头名称。 RestClient依赖于Net::HTTP。因此，例如，HTTP_USER标头在传输时实际上会转换为Http_user。

警示：限制

但是，Curl没有这个限制。它逐字传输标题名称。因此，您可以使用curb gem，而不是使用RestClient，它是libcurl的包装器。这似乎有效：

require "curb"
Curl::Easy.http_post("http://URL_REDACTED") do |http|
  http.headers["Accept"] = "application/json"
  http.headers["Content-Type"] = "application/json"
  http.headers["HTTP_USER"] = "userid"
  http.post_body = '{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}'
end

替代方案：excon

excon宝石是另一种可能性。它在纯Ruby中实现HTTP，而不依赖于Net::HTTP。它执行自己的头处理并允许ALL_CAPS头。所以这应该有效：

require "excon"
Excon.post(
  "http://URL_REDACTED",
  :headers => {
    "Accept" => "application/json",
    "Content-Type" => "application/json",
    "HTTP_USER" => "userid"
  },
  :body => '{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}'
)

无论如何，我认为你尝试连接的服务器最终在这里有问题，因为标题应该被评估为不区分大小写：Are HTTP headers case-sensitive?。如果服务器要求标题全部为大写，那就是错误。

Answer 2

RestClient README examples表示正确的用法是：

RestClient.post(url, payload, headers)

所以你要做的就是：

RestClient.post(
  "http://URL_REDACTED",
  '{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}',
  content_type: :json, 
  accept: :json,
  "HTTP_USER" => "userid"
)

我针对http://requestb.in进行了测试，得到了预期的标题和正文：

HEADERS

Total-Route-Time: 0
Connection: close
Via: 1.1 vegur
Connect-Time: 0
Http-User: userid
Content-Type: application/json
Content-Length: 55
User-Agent: rest-client/2.0.0 (darwin15.4.0 x86_64) ruby/2.3.1p112
X-Request-Id: c7cd819f-8901-41b9-8cbb-3b6d1895cd67
Accept-Encoding: gzip
Host: requestb.in
Accept: application/json

RAW BODY

{ "rtdt":"09/08/2016","jobs":[{"pid":53} , {"pid":54}]}

使用Rest-Client Ruby Gem发出POST请求时缺少头参数
