PHP Payment Development example, PHP payment instance

PHP Payment development process, share to everyone, for your reference, specific content as follows

1. Development environment
thinkphp 3.2.3
: Service number, certified
Development Domain Name: http://test.paywechat.com (custom domain name, external network unreachable)

2. Need relevant documents and permissions
Payment required for opening
Public Platform Developer Documentation: http://mp.weixin.qq.com/wiki/home/index.html
Payment Developer Documentation: https://pay.weixin.qq.com/wiki/doc/api/index.html
Payment SDK Download Address: https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

3. Development
Download the SDK to pay the PHP version, the file directory is:

Put the Cert and LIB directories of the payment SDK into the thinkphp directory for

Now introduce the payment authorization directory problem, the first is to pay the development configuration inside the payment authorization directory filled in,

Then fill in the JS interface security domain.

Finally set up page authorization

These settings finish, basically half done, note the set of directories and my thinkphp inside the directory.

4. Payment Configuration

Fill in the relevant configuration correctly.

/*** Configuring account information */class wxpayconfig{//======= "Basic information Settings" =====================================///** * TODO: Modify here to configure your own application for the merchant information * Public number information configuration * * APPID: Binding payment of APPID (must be configured, the opening email can be viewed) * * Mchid: Merchant Number (must be configured, can be viewed in the account opening mail) * * Key: Merchant payment key, refer to the Account opening mail setup (must Configuration, login to the merchant platform) * Set Address: Https://pay.weixin.qq.com/index.php/account/api_cert * * Appsecret: Public account Secert (only need to configure when JSAPI payment , login to the public platform, enter the developer center to set up), * get address: https://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev&token= 2005451881&LANG=ZH_CN * @var String */const APPID = '; Const MCHID = "; Const KEY = '; Const APPSECRET = "; ======= "Certificate path Settings" =====================================/** * TODO: Set the Merchant certificate path * Certification path, note that absolute path should be filled out (only refunds, cancellation of orders, you can log on to the merchant platform to download, * API certificate Download Address: Https://pay.weixin.qq.com/index.php/account/api_cert, need to install merchant operation Certificate before downloading) * @var path */Const SSLCERT_PATH = '. /cert/apiclient_cert.pem '; Const Sslkey_path = '.. /cert/apiclient_key.pem '; ======= "Curl proxy settings" ===================================/** * TODO: The agent machine is set up here, only when Proxy is required, no proxy is required, please set to 0.0.0.0 and 0 * This routine passes through CurlUsing the HTTP POST method, the proxy server can be modified here, * default curl_proxy_host=0.0.0.0 and curl_proxy_port=0, the agent is not turned on at this time (set if necessary) * @var Unknown_type */const Curl_proxy_host = "0.0.0.0";//"10.152.18.220"; Const CURL_PROXY_PORT = 0;//8080; ======= "Escalation information Configuration" ===================================/** * TODO: Interface call escalation level, default tight error escalation (note: escalation time is "1s", escalation regardless of success or failure "never throw exception", * Does not affect the interface invocation process), after you turn on escalation, it is convenient to monitor the quality of request calls, at least * turn on error escalation. * Escalation level, 0.

Now start to post the code:

Basically done here, you can open the http://test.paywechat.com/Charge/index.php/Test/index/at the end
My environment, HTTP server does not rewrite URL, pay to continue to explore, some places may write problems or shortcomings, hope everyone understanding, learn from each other.

The above is the PHP payment development of all the content, I hope that everyone's learning has helped, but also hope that we support a lot of help the home.
