thinkphp integrated micro-credit payment function _php Example

First effect Picture: I'm going to tell you. This article is written in the micro-letter payment (ordinary merchant rather than the service provider Merchant's unified JSPI) micro-letter payment:

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

Previous preparation:

1, micro-credit public number:

Unique AppID, Appscrect, interface permissions to set the domain name that can obtain user ID information permissions (each user will have a unique ID for different public, through this ID to obtain the user's micro-credit account basic information, details to see the micro-trust developer documentation), Set up a micro-credit payment authorization directory on the Micro-credit button (write to the controller that initiates the request), and set up the developer micro-account for the test whitelist (required when using the micro-trust developer tool)

2, micro-credit payment platform:

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

3, integration into the thinkphp logic:

Front-end micro-letter Payment button Set Click call Payment Initiator Controller method,

Controller operation, reference micro-letter payment category, get user OpenID, get order data, stitching out all ordinary merchant pre-payment JSP required data, display out of that custom payment page,

In the payment page click Pay, call the micro-letter provided by the JSPI to initiate the payment of the Scripet function to initiate payment,

After the payment completes, the page is redirected to the jump directory {: U (' controller/function)} ' set in the script function of the custom payment page, and the asynchronous (silent) Set asynchronous processing order logic (record payment time, marked as already paid, The mark is a micro-letter payment) or something,

Code:

The micro-mail payment button for my order page:

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

Initiate payment controller Wxpay:

<?php namespace Home\controller;
Use Think\controller; Micro-Credit Payment class Wxpaycontroller extends Controller {//Get the jump URI in the Access_token process, passing code into the JSAPI Payment page public Function Js_ap I_start () {if (!empty ($_get[' Order_key_num ')) {//session (Array (' pay_now_id ' =>$_get[' order_key_num '], ' expire ' =
   >3600));
  S (' pay_now_id ', $_get[' order_key_num '],3600);
  } vendor (' Weixinpay.wxpaypubhelper ');
  Use the Jsapi interface $jsApi = new \jsapi_pub (); ========= Step 1: Web page authorization to obtain the user openid============//via code to obtain OpenID if ($_get[' code '] = = ') {//jump $redirect _uri = ' http
    s://Current domain + module + controller + method '; $url = ' https://open.weixin.qq.com/connect/oauth2/authorize appid= public number Special idredirect_uri= '. $redirect _uri. '

    Header ("Location: $url");
   Exit (); }else{//Get OpenID $url = ' Https://api.weixin.qq.com/sns/oauth2/access_token? appid= public number id&secret= public number Scrept&amp Code= '. $_get[' code '. ' &grant_type=authorization_Code ';
  $openid _arr = Json_decode (file_get_contents ($url), true);
  $openid = $openid _arr[' OpenID '];
  $pay _now_id = S (' pay_now_id ');
   if ($pay _now_id) {$id = $pay _now_id;
   $o = D (' Order_info ');
   $order _info = $o->where (' order_id =%d ', $id)->find ();
   if (Empty ($order _info[' paycode ')) {$order _info[' paycode '] = ' weixin ';
   if ($order _info[' Is_pay ']) {$this->error (' current order already paid ');
  }else{$this->error ("No current order number!");
  $res = Array (' ORDER_SN ' => $order _info[' order_sn '], ' order_amount ' => $order _info[' Pay_money ']);
  ========= Step 2: Use the unified payment interface to obtain prepay_id============//using the Unified Payment interface $unifiedOrder = new \unifiedorder_pub (); 
  Set up uniform Payment interface parameters//set Required parameters//appid has been filled out, the merchant does not need to fill in the//mch_id has been filled, the merchant does not need to fill in the duplicate//noncestr has filled in, the merchant does not need to repeat fills//spbill_create_ip has filled, the merchant does not need
  Sign has been filled, the merchant does not need to fill $total _fee = $order _info[' Pay_money ']*100;
  $total _fee = $res [' Order_amount '];
  $total _fee = 1;
  Var_dump ($order _info[' Pay_money ');d ie;
  $body = "Order Payment";$unifiedOrder->setparameter ("OpenID", "$openid");//user identification $unifiedOrder->setparameter ("body", ' commodity purchase ');//Product Description/ /custom order number, here for example $unifiedOrder->setparameter ("Out_trade_no", $order _info[' order_sn ');//Merchant Order number $unifiedOrder-> Setparameter ("Total_fee", $total _fee);//Total amount//$unifiedOrder->setparameter ("Attach", "order_sn={$res [' ORDER_SN '] ]//Additional data $unifiedOrder->setparameter ("Notify_url", \wxpayconf_pub::notify_url);//notification address $unifiedOrder-> Setparameter ("Trade_type", "JSAPI")//transaction type//non-required, the merchant may fill in the actual situation by filling//$unifiedOrder->setparameter ("sub_mch_id", " XXXX ");//Merchant number//$unifiedOrder->setparameter (" Device_info "," XXXX ");//device number//$unifiedOrder->setparameter (" Attach "," xxxx ")//Additional data//$unifiedOrder->setparameter (" Time_start "," xxxx "),//Transaction start time//$unifiedOrder-> Setparameter ("Time_expire", "xxxx");//transaction end time//$unifiedOrder->setparameter ("Goods_tag", "xxxx");//mark of goods//$ Unifiedorder->setparameter ("OpenID", "XXXX");//user ID//$unifiedOrder-&GT;SETPArameter ("product_id", "XXXX");//commodity id $prepay _id = $unifiedOrder->getprepayid ();

  $jsApiParameters = $jsApi->getparameters ();
  $wxconf = Json_decode ($jsApiParameters, true);
  if ($wxconf [' package '] = = ' prepay_id= ') {$this->error (' current order is abnormal! ')

  ///asynchronous notification URL, the merchant based on the actual development process to set Public function Notify_url () {Vendor (' weixinpay.wxpaypubhelper ');
  Use the universal notification interface $notify = new \notify_pub (); 
  A callback $xml for storing a micro-letter = $GLOBALS [' Http_raw_post_data '];
  $notify->savedata ($xml);
  Verify the signature and respond to the micro-letter.
  When you interact with a background notification, if the micro-letter received the merchant's reply is not a success or timeout, the micro-letter believes that the notification failed,//micro-letter through a certain strategy (such as 30 minutes a total of 8 times) to periodically restart the notification,///As far as possible to increase the success rate of notification, but the if ($notify->checksign () = FALSE) {$notify->setreturnparameter ("Return_code", "FAIL");//Return Status code $notify->set Returnparameter ("Return_msg", "Signature failed//Return information}else{$notify->setreturnparameter ("Return_code", "SUCCESS");/Set return code} $RETURNXML = $notify->retu

And then there's the class file:

That CACert is a certificate store directory, the certificate does not necessarily need;

The vendor folder can be found in my file.

The above is a small set to introduce the thinkphp integrated micro-credit payment function, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
