PHP micro-Credit Payment interface development Program _php skills

PHP micro-Credit Payment interface development program to explain :

Necessary:
AppID//Public Number Background Developer Center Access (same as in mail)

mchid//in Mail

key//Merchant backstage oneself set up

Appsecret//Public Number Developer Center Access
Two certificate files, received Apiclient_cert.pem apiclient_key.pem in Mail
Precautions :
Public number background micro-letter Payment-"Development configuration-" New test directory and test personal micro-signal.
Developer Center-"website authorization to get user profile-" modify it to your test domain. Otherwise a Redirect_uri parameter error will occur
—————————— follow-up to be completed ——————-
The micro-credit payment ready page backstage three times to operate:

1. Get OpenID

Use the Jsapi interface
 
 code to copy the code as follows
  $jsApi = new Jsapi_pub ();
 
  ========= Step 1: Web page authorization to obtain the user openid============//
  via code to obtain OpenID
  if (!isset ($_get[' Code '))
  {
    // Trigger the micro-letter return code code
    $url = $jsApi->createoauthurlforcode (wxpayconf_pub::js_api_call_url);
    echo $url;
    Header ("Location: $url");
  } else
  {
    //Get code code to get OpenID
    $code = $_get[' code '];
    $jsApi->setcode ($code);
    $openid = $jsApi->getopenid ();
  }

At the beginning of the first step also encountered problems, can not get OpenID this and some of the server-related, demo is used in the way curl get.
Strange that my server curl has been unable to get. Later changed into file_get_contents can be normal access.
But that's not the way to solve it. Because more curl operations are needed later.
See the development document there is a place to write a certificate operation requires Libcurl 7.20.1 version, and then I have been in the whole server want to improve the Linux PHP Curl version. The last thing I did was switch to another Windows server.
Let's do this for a while, and then debug it the next time you need it.

Step two: get and pay Order number ID
The code is as follows

$unifiedOrder = new Unifiedorder_pub ();
  Var_dump ($unifiedOrder); 
  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 in, the merchant does not need to fill in $unifiedOrder->setparameter ("OpenID", "$openid");//Product Description $unifiedOrder->setparameter ("body
  "," Contribution to a Penny ")//Product Description/Custom order number, here for example $timeStamp = time (); $out _trade_no = wxpayconf_pub::appid. "
  $timeStamp "; $unifiedOrder->setparameter ("Out_trade_no", "$out _trade_no");//Merchant Order number $unifiedOrder->setparameter ("Total_ Fee "," 1 ")//Total amount $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 identification//$unifiedOrder->setparameter ("product_id", "xxxx");
   
  Product ID $prepay _id = $unifiedOrder->getprepayid ();
  Echo ' prepay_id: ';

 Var_dump ($prepay _id);

This step also encountered a lot of problems.
First, the micro-credit payment test is more difficult, only in the micro-letter can be tested. I use the phone brush to brush.
Second, the use of Var_dump debugging is not a good amount. Printing some XML-formatted files displays only the character length and does not display the content. So log in the form of writing on the server debugging, log code:
The code is as follows

Print log
  function log_d ($word) 
  {
    $log _name= "./logd.log";//log file path
    $fp = fopen ($log _name, "a");
    Flock ($FP, lock_ex);
    Fwrite ($FP, "date of execution:". Strftime ("%y-%m-%d-%h:%m:%s", Time ()). " N ". $word." nn ");
    Flock ($FP, lock_un);
    Fclose ($FP);
  

In the demo inside the wxpaypubhelper.php inside with $this->log_d (XXX);
At the beginning, due to my mchid and AppID do not match has been an error. They gave me the wrong account. At first I didn't know how to try. This step is debugged in Getprepayid () var_dump ($this->result); You can see the error code.

Step three: generate the payment front-end JS code ready to the Web page:
The code is as follows

$jsApi->setprepayid ($prepay _id);
 
$jsApiParameters = $jsApi->getparameters ();

———————-Click to go to pay ————————-

This part has also encountered the problem:
Android returns to "System:access_denied" and iOS returns to "access_control:not_allowed"
searched a lot of Baidu. Actually already saw this thing to have not noticed!
The page on which the authorization request originated must be a page under the authorization directory, not a subdirectory. Otherwise, an error is returned
Payment file I put in the/domain/pay/demo/
At the beginning of the time I have been to/domain/pay/end thought it can be. Support subdirectories, the result is not!.
————————— finally look at the figure —————

Wxpay1
Wxpay3
Wxpay2

————— – The Xmljs —————— in the process –
Build and Pay Order ID to be submitted:
The code is as follows

<xml>
 <openid><![ Cdata[ou9dht0l8qfli1fop-kj5x1mdwsm]]></openid>
 <body><![ cdata[contribution]]></body>
 <out_trade_no><![ cdata[wx88888888888888881414411779]]></out_trade_no>
 <total_fee>1</total_fee>
 <notify_url><! [cdata[http://shanmao.me/wxpay/notify_url.php]]></notify_url>
 <trade_type><![ Cdata[jsapi]]></trade_type>
 <appid><![ cdata[wx8888888888888888]]></appid>

 <sign><![ Cdata[2d8a96553672d56bb2908ce4b0a23d0f]]></sign>
</xml>

Returned correctly after submission, which contains the perpay_id:

<xml>
 <return_code><![ Cdata[success]]></return_code> 
 <return_msg><![ Cdata[ok]]></return_msg> 
 <appid><![ Cdata[wx8888888888888888]]></appid> 
 <mch_id><![ Cdata[10012345]]></mch_id> 
 <nonce_str><![ Cdata[be8yx7gjcdtct7cr]]></nonce_str>

 <prepay_id><![ Cdata[wx201410272009395522657a690389285100]]></prepay_id> 
 <trade_type><![ Cdata[jsapi]]></trade_type> 
</xml>

Generate the payment with JS:

{"
  appId": "wx8888888888888888", "
  TimeStamp": "1414411784",
  "Noncestr": " Gbwr71b5no6q6ne18c8up1u7l7he2y75 ","
  Package ":" prepay_id=wx201410272009395522657a690389285100 ",
  " Signtype ":" MD5 ","
  paysign ":" 9c6747193720f851eb876299d59f6c7d "
}

Notification XML returned when payment is successful:

This one of the data I random, we refer to the format bar. Note In addition the case sensitivity.
