ruby-on-rails - 在 Rails 中发送 POST 请求

Question

我将如何在 Rails 设置中发送以下格式的 HTTP POST 请求:

curl https://api.venmo.com/v1/payments -d access_token=4e4sw1111111111t8an8dektggtcbb45 -d     email="someemail@gmail.com" -d amount=5 -d note="Delivery."

我想让用户将电子邮件/金额/备注参数输入到网页上的表单中，然后将该数据(当用户单击提交按钮时)传递到存储 access_token 参数的 Controller 中，然后触发关闭 POST 请求。

到目前为止，我已尝试使用此方法设置 Controller (并从 View html.erb 调用它):

def make_payment
  if !params[:access_token].nil?

    form_data = {
        "email" => @email_to,
        "amount" => @amount_to,
        "note" => @note_to,
        "access_token" => :access_token
    }
    url = "https://api.venmo.com/v1/payments"
    request = Net::HTTP::Post.new(url, form_data)

    response = http.request(request)

   end
end

这是我当前的 View 设置:

  <div class="box box-warning">
                        <div class="box-header">
                          <h3 class="box-title">Pay Bill using Venmo Account</h3>
                            <div id="payment_note_input">
                            <input id="payment_note" type="text" class="form-control" required placeholder="add a note to your payment">
                            </div>
                            <div id="payment_target_input" >
                            <input id="payment_target" type="text" class="form-control" required placeholder="pay an email address">
                            </div>
                            <div id="payment_amount_input">
                            <input id="payment_amount" type="text" class="form-control" required placeholder="enter the payment amount! ">
                            </div>
                            </br>
                        <button class="btn btn-danger" type="button" onClick= <%=make_payment%> > Make payment</button>
                    </div>

我觉得我离解决方案很近了......

Answer 1

您可以使用 httpparty gem为实现这一点，只需一行即可轻松使用:

response = HTTParty.post("https://example.com?param1=value1",
              :body => {:text => data}.to_json,
              :headers => {'Content-Type' => 'application/json'}
)

如果没有特定的 Body 或 Header，可以删除 Body 和 Header，

如果你想实现 Get 请求就更简单了:

responce = HTTParty.get('http://example.com.json')
json=JSON.parse(responce.body) # in case you expect json responce
