thinkphp micro-Credit payment function

This article mainly introduces the thinkphp integrated payment function of the relevant information, very good, with reference value, the need for friends can refer to the next

First: I want to tell you that this article is written in the payment of (the common merchant rather than the merchant's uniform order Jspi) Payment:

In fact, the integration of the SDK failed, with a blog blogger integrated code, here to write notes:

Front Preparation:

1. Public Number:

Unique AppID, Appscrect, interface permissions set the domain name that can get the user ID information permission (each user will have a unique ID for different public, through this ID to get the basic information of the user account, the details of the developer documentation), In the payment button out of the set up payment authorization directory (write to the controller that initiated the request layer), set the developer account for the test whitelist (required when using developer tools)

2. Payment Platform:

Merchant Platform login account, payment key (can be set at any time, only one),

3, integration into the thinkphp logic:

Front-End Payment button settings Click Invoke Payment Initiator Controller method,

The controller runs, refers to the payment class, obtains the user OpenID, obtains the order data, stitching out all the ordinary merchant pre-payment JSP needs data, display the custom payment page,

On the payment page click Pay, call the provided JSPI initiate payment Scripet function to initiate the payment,

After payment is completed, the page is redirected to the (jump directory {: U (' Controller/function)}), which is set in the script function of the custom payment page, and the asynchronous (silent) setting of the Asynchronous Processing order logic (record payment time, Mark as already paid, Mark is paid) and the like

Code:

The payment button on my order page:

<a href= "{: U (' Wxpay/js_api_start ', Array (' order_key_num ' = $v [' order_key_num])}" > Payment </a>

Initiate payment controller Wxpay:
