WeChat sharing configuration and examples
WeChat public platform server configuration
The following is the code of wx_check.php, put this file in the newly created [wx_check] folder under your server domain name.
<?php
define("TOKEN", "你的token（任意字符串，与服务器上相同）");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();
class wechatCallbackapiTest
{
public function valid()
{
$echoStr = $_GET["echostr"];
if($this->checkSignature()){
echo $echoStr;
exit;
}
}
public function responseMsg()
{
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
if (!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content><FuncFlag>0</FuncFlag></xml>";
if(!empty( $keyword ))
{
$msgType = "text";
$contentStr = "Welcome to wechat world!";
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;
}else{
echo "Input something...";
}
}else {
echo "";
exit;
}
}
private function checkSignature()
{
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
I found a strange phenomenon that after adding the wx_ prefix to the folder and file name, I passed the verification in seconds, so I named the name this wx_xxx here
WeChat public account sharing development
development process
Download the WeChat sample
which contains
the sample code on sample.php.
Open sample.php and delete the html code, and
the last step above is to separate the code from the data
, then change the name of the sample to a very powerful name, and change the parent folder [PHP] as well. Note, it is best to use English,
put it into the root directory of the server domain name folder
, create a new test project,
share.png is the picture displayed when sharing, preferably 200*200 pixel size
testshare.php is the code
and then in your code write like this
<?php
require_once "../牛逼名字/牛逼名字.php";
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
TEST share

Put it into the root directory of the server domain name.
The browser accesses this file, and then sends the link to WeChat. Open WeChat and click on the upper left corner to share with friends and share with Moments
error resolution
error 1 url domain
During the development process, you will encounter situations that cannot be shared, and an error will be reported
errmsg config;invalid url domain
This is because the js security domain name is not configured.
Solution
- Open the WeChat public platform
- Find [Settings]
- Find [Function Settings] - "[js interface security domain name] - "[Settings]
- keep
Error 2 40164 invalid ip xxx
errMsg:config :invalid signature
This is a prompt for an illegal signature. click debug
Solution
Enter appid and secret. See if it prompts this question. If so, you need to add the prompted ip address to the WeChat whitelist
(strangely, I have been using it well before, and then the server environment changed from laragon to phpstudy and this problem occurred)
Error 3 The get method cannot get res
The get method of the official sample.php cannot get res.
Solution
As shown in the picture, change the verification to no verification (there is a problem to be verified, that is, after changing true to false, does the white list not need to be set?)
error 4 file not found
When opening the link, it still prompts illegal signature
errMsg:config :invalid signature
Solution
Check the code of sample.php
to see if the url shown in the figure above is written correctly.
The url commented out above will not automatically generate the two files in the above picture when called. It needs to be copied to the project project. and cannot be empty. Must have valid content.
There are two ways to obtain the valid content.
1. Use the WeChat online debugging tool to obtain the corresponding value
. 2. Use the url shown in the figure below. Without these two files, it can be automatically generated. In this way, there is a file.
Generally, I use the uncommented url in the picture above, which is convenient and smart.
