Payment verification signature payment failed? —— WeChat Pay app payment
Payment verification signature payment failed? —— WeChat Pay app payment
Situation description:
1. Call the same order interface and get the prepay_id equivalent value!
2. Before submitting data to the app, there is a secondary signature. I signed it according to the rules! //Please check if the code I wrote is correct
3. Why does this problem occur?
4. I beg God for guidance!
This is my secondary signature code:
............ //Set parameters, etc.
$wx_result = $wechatAppPay->unifiedOrder( $params );//调用同一下单接口，并成功返回结果 //开始生成二次签名 $sign_array = array();//第二次签名需要的参数 $sign_array['appid'] = $wx_result['appid']; $sign_array['mch_id'] = $wx_result['mch_id']; $sign_array['prepay_id'] = $wx_result['prepay_id']; $sign_array['nonce_str'] = $wx_result['nonce_str']; $sign_array['timeStamp'] = time(); $sign_array['package'] = $wx_result['Sign=WXPay']; $sign_two = $wechatAppPay->MakeSign($sign_array);//调用签名生成函数
The following is my function code to generate signatures:
/**
* 生成签名
* @return 签名
*/
public function MakeSign( $params ){
//签名步骤一：按字典序排序数组参数
ksort($params);
$string = $this->ToUrlParams($params);//调用拼接函数
//签名步骤二：在string后加入KEY
$string = $string . "&key=".$this->key;
//签名步骤三：MD5加密
$string = md5($string);
//签名步骤四：所有字符转为大写
$result = strtoupper($string);
return $result;
}
/**
* 将参数拼接为url: key=value&key=value
* @param $params
* @return string
*/
public function ToUrlParams( $params ){
$string = '';
if( !empty($params) ){
$array = array();
foreach( $params as $key => $value ){
$array[] = $key.'='.$value;
}
$string = implode("&",$array);
}
return $string;
}This question has been resolved Solved, the reason is that the parameter name in the second signature is wrong.
//////////////////////////////Update/////////////////// ///////////////////////////////////////////////////// ///////////////////////////////////////////////////// /////////////////////////////////
But I don’t know how to write the callback! !
But I can’t receive the value (I can’t receive the general notification of payment results from WeChat), and I don’t know what’s going on
Receive WeChat payment asynchronous notification callback address:
$notify_url = 'http://www.XXXXXX.com/index.php/apps/cart/wxResult';
//微信支付回调函数
public function wxResult()
{
$data = array();
$data = $this->wechatAppPay->getNotifyData();//调用获取数据函数
////////********逻辑处理********//////////
$data2 = $this->wechatAppPay->replyNotify();//接收通知成功后应答输出XML数据
$this->jsonmsg($data);
}Function to get notification data:
/**
*
* 获取支付结果通知数据
* return array
*/
public function getNotifyData(){
//获取通知的数据
$xml = $GLOBALS['HTTP_RAW_POST_DATA'];
$data = array();
if( empty($xml) ){
return false;
}
$data = $this->xml_to_data( $xml );
if( !empty($data['return_code']) ){
if( $data['return_code'] == 'FAIL' ){
return false;
}
}
return $data;
}Response output XML data function after successfully receiving notification:
/**
* 接收通知成功后应答输出XML数据
* @param string $xml
*/
public function replyNotify(){
$data['return_code'] = 'SUCCESS';
$data['return_msg'] = 'OK';
$xml = $this->data_to_xml( $data );
echo $xml;
die();
}** Solved
///////Updated/////////////////Merchant system for payment result notification Signature verification of the content /////////////////////////////////**
is working on the content of the payment result notification from the merchant system How to do signature verification?
What is it? What is the logical idea?
Reply content:
Payment interface document
Fields specified in the document
appid
partnerid
prepayid
package
noncestr
timestamp
sign
Please do not change the case of parameter names, also Don't add Underline or something. I have encountered this problem before and it has been solved.
Hello, I also encountered the same problem. I wonder if you have solved it?
Is the parameter name involved in the md5 calculation?
The timestamp of the secondary signature is the timestamp when pre_payid was generated

PHP and Python: Comparing Two Popular Programming Languages
Apr 14, 2025 am 12:13 AM
PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
PHP in Action: Real-World Examples and Applications
Apr 14, 2025 am 12:19 AM
PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
