PHP Micro-Credit Payment Development Example _php example

PHP Micro-credit payment development process, to share with you for your reference, the specific content as follows

1. Development environment
thinkphp 3.2.3
Micro-letter: Service number, certified
Development Domain Name: http://test.paywechat.com (custom domain name, extranet inaccessible)

2. Need relevant documents and authority
Micro-letter payment to be opened for application
Micro-trust public Platform Developer Documentation: http://mp.weixin.qq.com/wiki/home/index.html
Micro-credit Payment developer Documentation: https://pay.weixin.qq.com/wiki/doc/api/index.html
Micro-credit Payment SDK download address: https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

3. Development
Download the micro-letter payment PHP version of the SDK, file directory for the following figure:

Put the Cert and Lib directory of the micro-credit payment SDK into the thinkphp directory

Now introduce the issue of micro-letter Payment Authorization directory, the first is the micro-credit payment development configuration inside the payment authorization directory to fill out,

Then fill in the JS interface security domain.

Finally set up the page authorization

These settings are finished, basically half done, note the set directory and my thinkphp inside the directory.

4. Micro-Credit Payment configuration

Fill in the relevant configuration correctly.

/** * Configuration Account information */class Wxpayconfig {//======= "Basic information Settings" =====================================///** * TODO: Modify here to configure for yourself Application for merchant information * Micro-trust Information configuration * * APPID: Binding payment APPID (must be configured, open account Mail can be viewed) * * Mchid: Merchant Number (must be configured, account open Mail can be viewed) * Key: Merchant payment key, refer to account opening mail settings (must be matched with Set, login merchant platform set up by itself) * Address: Https://pay.weixin.qq.com/index.php/account/api_cert * * Appsecret: Public account Secert (only JSAPI payment needs to be configured, Login to the public platform, access to the developer Center can be set up), * get address: https://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev&token=

Basically done here, you can open the http://test.paywechat.com/Charge/index.php/Test/index/at the micro-letter end
my environment, HTTP server did not rewrite the URL, micro-letter payment continue to explore, some places may write problems or deficiencies, hope everyone understanding, learn from each other.

The above is the whole content of the PHP micro-credit payment development, I hope to help you learn, but also hope that we support the cloud habitat community.
