相信刚接触微信公众平台开发的程序猿来说，一般都会遇到这样的问题，在微信公众号后台中设置基本配置时，提示“token验证失败”，其实微信官方也给出了“接入指南”，但是文章真的太长了，相信很多人都没耐心看完，小编也是其中一个，所以就直接网上解决方案，下面跟大家分享一下，验证代码如下（这个文件就是你填写回调地址的目标文件）：

define("TOKEN", "这里填写你的token");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();

class wechatCallbackapiTest{
	
	public function valid()	{
		$echoStr = $_GET["echostr"];
		//valid signature , option
		if($this->checkSignature()){
			echo $echoStr;
			exit;
		}
	}
	
	public function responseMsg() {
		//get post data, May be due to the different environments
		$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
		//extract post data
		if (!emptyempty($postStr)){
			$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
			$fromUsername = $postObj->FromUserName;
			$toUsername = $postObj->ToUserName;
			$keyword = trim($postObj->Content);
			$time = time();
			$textTpl = "%s0";
			if(!emptyempty( $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, SORT_STRING);
		$tmpStr = implode( $tmpArr );
		$tmpStr = sha1( $tmpStr );
		if( $tmpStr == $signature ){
			return true;
		}else{
			return false;
		}
	}
}
