我有智能按钮在沙盒中“工作”，但我想不出任何方法将智能按钮成功附加到创建订单的订单表单。使用条纹元素，它非常即插即用，因为它位于页面上并且是表单本身的一部分，但是使用PayPal进行重定向时，我似乎无法想到某种方式。
这需要javascript还是我可以在没有它的情况下执行此操作，除了已经存在的内容？
形成：
<%= form_for(@order, url: listing_orders_path([@listing, @listing_video]), html: {id: "payment_form-4"} ) do |form| %>
<%= form.label :name, "Your Name", class: "form-label" %>
<%= form.text_field :name, class: "form-control", required: true, placeholder: "John" %>
#stripe code here (not important)
<%= form.submit %>
<div id="paypal-button-container"></div>
<!-- Include the PayPal JavaScript SDK -->
<script src="https://www.paypal.com/sdk/js?client-id=sb¤cy=USD"></script>
<script>
// Render the PayPal button into #paypal-button-container
paypal.Buttons({
// Set up the transaction
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
value: <%= @listing.listing_video.price %>
}
}]
});
},
// Finalize the transaction
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Show a success message to the buyer
alert('Transaction completed by ' + details.payer.name.given_name + '!');
});
}
}).render('#paypal-button-container');
</script>
在Controller中创建方法：
require 'paypal-checkout-sdk'
client_id = Rails.application.credentials[Rails.env.to_sym].dig(:paypal, :client_id)
client_secret = Rails.application.credentials[Rails.env.to_sym].dig(:paypal, :client_secret)
# Creating an environment
environment = PayPal::SandboxEnvironment.new(client_id, client_secret)
client = PayPal::PayPalHttpClient.new(environment)
@amount_paypal = (@listing.listing_video.price || @listing.listing_tweet.price)
request = PayPalCheckoutSdk::Orders::OrdersCreateRequest::new
request.request_body(
{
intent: 'AUTHORIZE',
purchase_units: [
{
amount: {
currency_code: 'USD',
value: "#{@amount_paypal}"
}
}
]
}
)
begin
# Call API with your client and get a response for your call
response = client.execute(request)
# If call returns body in response, you can get the deserialized version from the result attribute of the response
order = response.result
puts order
@order.paypal_authorization_token = response.id
rescue BraintreeHttp::HttpError => ioe
# Something went wrong server-side
puts ioe.status_code
puts ioe.headers['debug_id']
end
如何将PayPal智能按钮与表单绑定，以便在付款完成后，如果成功，它会创建订单？
UPDATE :::::::
创建了PaypalPayments控制器和模型：
控制器：
def create
@paypal_payment = PaypalPayment.new
@listing = Listing.find_by(params[:listing_id])
require 'paypal-checkout-sdk'
client_id = "#{Rails.application.credentials[Rails.env.to_sym].dig(:paypal, :client_id)}"
client_secret = "#{Rails.application.credentials[Rails.env.to_sym].dig(:paypal, :client_secret)}"
# Creating an environment
environment = PayPal::SandboxEnvironment.new(client_id, client_secret)
client = PayPal::PayPalHttpClient.new(environment)
@amount_paypal = @listing.listing_video.price
request = PayPalCheckoutSdk::Orders::OrdersCreateRequest::new
@paypal_payment = request.request_body({
intent: "AUTHORIZE",
purchase_units: [
{
amount: {
currency_code: "USD",
value: "#{@amount_paypal}"
}
}
]
})
begin
# Call API with your client and get a response for your call
response = client.execute(request)
# If call returns body in response, you can get the deserialized version from the result attribute of the response
order = response.result
puts order
# @order.paypal_authorization_token = response.id
rescue BraintreeHttp::HttpError => ioe
# Something went wrong server-side
puts ioe.status_code
puts ioe.headers["debug_id"]
end
# if @paypal_payment.create
# render json: {success: true}
# else
# render json: {success: false}
# end
end
Javascript在视图中：
paypal.Buttons({
createOrder: function() {
return fetch('/paypal_payments', {
method: 'post',
headers: {
'content-type': 'application/json'
}
}).then(function(res) {
return res.json();
}).then(function(data) {
return data.orderID;
});
},
onApprove: function(data) {
return fetch('/orders', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID
})
}).then(function(res) {
return res.json();
}).then(function(details) {
alert('Authorization created for ' + details.payer_given_name);
});
},
}).render('#paypal-button-container');
有了这个，paypal框出现了，但随后在CMD加载后立即消失：
#<OpenStruct id="1Pxxxxxxx394U", links=[#<OpenStruct href="https://api.sandbox.paypal.com/v2/checkout/orders/1P0xxxxxxx394U", rel="self", method="GET">, #<OpenStruct href="https://www.sandbox.paypal.com/checkoutnow?token=1P07xxxxxxx94U", rel="approve", method="GET">, #<OpenStruct href="https://api.sandbox.paypal.com/v2/checkout/orders/1Pxxxxxxx4U", rel="update", method="PATCH">, #<OpenStruct href="https://api.sandbox.paypal.com/v2/checkout/orders/1P07xxxxxxx394U/authorize", rel="authorize", method="POST">], status="CREATED">

我没有使用过智能按钮。但是，在创建操作中不应该有“更多代码”。如果您遵循MVC和rails约定。您似乎需要单独的控制器操作来独立于创建操作处理付款授权。但是，如果你可以在你的javascript中达到这一点，这里是你如何将数据从paypal javascript发送回你的控制器的例子，这将需要一些工作，但希望它指出你正确的方向：
// Finalize the transaction
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Show a success message to the buyer
alert('Transaction completed by ' + details.payer.name.given_name + '!');
// here is where you should send info to your controller action via ajax.
$.ajax({
type: "POST",
url: "/orders",
data: data,
success: function(data) {
alert(data); // or whatever you wanna do here
return false;
},
error: function(data) {
alert(data); // or something else
return false;
}
});
});
}
