PHP payment development instance and php payment instance

The PHP payment development process is for your reference. The details are as follows:

1. Development Environment
Thinkphp 3.2.3
: Service number, certified
Development Domain Name: http://test.paywechat.com (custom domain name, Internet inaccessible)

2. Related Files and permissions are required.
Apply for activation for payment
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: https://pay.weixin.qq.com/wiki/doc/api/jsapi.php? Chapter = 11_1

3. Development
Download the php sdk. The file directory is:

 

Put the Cert and Lib directories of the payment SDK into Thinkphp. The directory is

 

This section describes the payment authorization directory. First, fill in the payment authorization directory in the payment development configuration,

Then fill in the JS interface security domain.

Finally, set webpage authorization

After completing these settings, you will be half done. Pay attention to the Set Directory and the directory in my thinkphp.

4. Payment Configuration

Enter the relevant configuration correctly.

/*** Configure account information */class WxPayConfig {// ======== [basic information settings] ========== ========================================/// *** TODO: modify the configuration here to the merchant information you have applied for * Public Account information configuration ** APPID: bound to the payment APPID (required, which can be viewed in the account opening email) ** MCHID: merchant ID (required, which can be viewed in the account opening email) ** KEY: Merchant's payment KEY. For details, refer to the account opening email settings (required, which can be set by logging on to the merchant platform) * set the address: https://pay.weixin.qq.com/index.php/account/api_cert ** APPSECRET: Public Account secert (only JSAPI pay when you need to configure, login to the public platform, enter the Developer Center can be set), * Get address: https://mp.weixin.qq.com/advanced/ad Vanced? 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 * certificate path.

It is set only when proxy is required. No proxy is required. Set it to 0.0.0.0 and 0 *. This routine uses the http post method through curl. Here the proxy server can be modified, * CURL_PROXY_HOST = 0.0.0.0 and CURL_PROXY_PORT = 0 by default.

If reporting succeeds or fails, [never throws an exception], * the interface call process is not affected.) After reporting is enabled, the quality of request calls can be easily monitored, it is recommended that at least * enable error reporting. * Report Level: 0. Disable reporting; 1. Report errors only; 2. Full Report * @ var int */const REPORT_LEVENL = 1 ;}

Basically done here, you can open the http://test.paywechat.com/Charge/index.php/Test/index/ at the end
In my environment, the HTTP server does not rewrite the url, and payment continues to be explored. In some places, there may be problems or deficiencies in writing. I hope you can understand each other and learn from each other.

The above is all about PHP payment development. I hope it will be helpful to everyone's learning, and I hope you can support more help.
