HomeBackend DevelopmentPHP Tutorial来技术论坛请教大神了,关于微信接口开发的

代码直接用微信官方的例子来做小修改的
出现的问题是,部分消息验证不通过
例如我发送了一条信息,如果验证通过,回复欢迎信息,如果验证不通过,回复false关键词
我发了5条信息,有时候有两条回复false,有时候有三条false。
为什么会有验证不通过的现象?
求大神指导

define("TOKEN", "token");$wechatObj = new wechatCallbackapiTest();//$wechatObj->valid();$wechatObj->run();class wechatCallbackapiTest{	public function valid()    {        $echoStr = $_GET["echostr"];        //valid signature , option        if($this->checkSignature()){        	echo $echoStr;        	exit;        }    }        public function run() {    	if($this->checkSignature()) {    		$this->responseMsg();    	}else{    		$this->responseMsg("false");    	}    }    public function responseMsg($contentStr = "Welcome to wechat world!")    {		//get post data, May be due to the different environments		$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];      	//extract post data		if (!empty($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;		}	}}


回复讨论(解决方案)

记录日志,把获取合法返回的数据都记到日志里,看看成功和失败的日志区别来分析吧

你的验证参数字典排序不对
sort($tmpArr);改成sort($tmpArr, SORT_STRING);

补充一下:至于你有时成功,有时失败,是因为成功的数据正好是两种排序结果是一样的。

你的验证参数字典排序不对
sort($tmpArr);改成sort($tmpArr, SORT_STRING);



成了,感谢。
验证方法直接复制微信官方的例子,我太相信他们了,坑啊

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
