PHP Development Micro-credit Payment Enterprise payment Instance code

Enterprise Payment Application Scenario: The public number to pay attention to users, such as processing refunds, financial settlement, and so on, this article mainly share with you the PHP development Payment Enterprise Payment instance code, hope to help everyone.

Description

1. Certificates need to use the certificate inside their merchant (note: The certificate path must be an absolute path and the following error will be reported if a relative path is used.)

Unable to use client certificate (no key found or wrong pass phrase?)

2.appid,secret and key to fill their own can.

Let's talk about the realization of the idea:

1. First get OpenID, see below for specific methods.

2. Fill in the required parameters, generate signatures, etc., see below for specific methods.

/** * API Parameters * @var array * ' mch_appid ' # public number AppID * ' Mchid ' # merchant number * ' Device_info ' # device number * ' Nonce_str ' # random String * ' Partner_ Trade_no ' # Merchant Order number * ' OpenID ' # Beneficiary User OpenID * ' check_name ' # Verify user name option for authenticated Users * ' Re_user_name ' # Payee User name * ' Amount ' # Payment amount * ' desc ' # Enterprise Payment description * ' spbill_create_ip ' # IP address * ' sign ' # signature */

1. Get Code (index.php page)

<?php//Information callback file is located on the server location $str= "http://www.xxx.com/company_pay/getInfo.php"; $str _url=urlencode ($STR); $appid = " xxxx3e5273505e "; $url = ' https://open.weixin.qq.com/connect/oauth2/authorize?appid= '. $appid. ' &redirect_uri= '. $str _url. ' &response_type=code&scope=snsapi_userinfo&state=state#wechat_redirect '; header ("Location:". $url);? >

2. Information callback page code processing (getinfo.php)

<?php$appid = "wxxxxx3505e";//The Appid$secret of your public platform = "fxxxxx71xxx4cda2a671";//Your public platform Secret$code = $_get["code"];$ Get_token_url = ' https://api.weixin.qq.com/sns/oauth2/access_token?appid= '. $appid.

Curl_error ($ch);} Curl_close ($ch); echo "-----<br/> Request return value:"; Echo $infos->return_code;echo "<br/>*****";? >

3. Generating a signature function file (api.php)

<?php/** * Function: Format parameters, the signature process needs to use */function Formatbizqueryparamap ($paraMap, $urlencode) {$buff = "";    Ksort ($PARAMAP);        foreach ($paraMap as $k = + $v) {if ($urlencode) {$v = UrlEncode ($v); } $buff. = $k. "=" . $v.    "&";    } if (strlen ($buff) > 0) {$reqPar = substr ($buff, 0, strlen ($buff)-1); } return $reqPar;}    /** * Function: Generate signature */function getsign ($OBJ) {foreach ($Obj as $k = = $v) {$Parameters [$k] = $v;    }//Signature step one: sorted by dictionary order parameter Ksort ($Parameters);    $String = Formatbizqueryparamap ($Parameters, false); Echo ' "string1" '. $String. '    </br> '; Signature Step Two: Add key $String after String = $String. "    &key=vhmake666vhmake666vhmake666vhmak "; echo "string2" ". $String."    </br> ";    Signature Step Three: MD5 encryption $String = MD5 ($String); echo "String3" ". $String."    </br> ";    Signature Step four: All characters to uppercase $result _ = Strtoupper ($String); echo "Result". $result _. "    </br> "; return $result _;}
