配置成功,当微信用户向测试账号发消息时, 使用网页调试工具,显示请求失败
详细信息:
本人写了一个component(已经在配置文件中web.php成功加载),
配置代码如下:

本人写了一个component(已经在配置文件中web.php成功加载),
配置代码如下:
"components" => [ "weixinMessage" => [ "class" => "app\components\Weixin", ], ... ...
自定义的component Weixin.php 代码如下:
namespace app\components; use yii\base\Component; use yii\base\InvalidConfigException; define("TOKEN", "weixin"); class Weixin extends Component { public function valid() { $echoStr = $_GET["echostr"]; if($this->checkSignature()){ echo $echoStr; exit; } } public function responseMsgs() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection, the best way is to check the validity of xml by yourself */ libxml_disable_entity_loader(true); $postObj = simplexml_load_string($postStr, "SimpleXMLElement", LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->FromUserName; $keyword = trim($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; } } public function checkSignature() { // you must define TOKEN by yourself if (!defined("TOKEN")) { throw new Exception("TOKEN is not defined!"); } $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); // use SORT_STRING rule sort($tmpArr, SORT_STRING); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } }
本人用的是yii framework 2.0 basic template, 在action里面直接调用component里的valid()方法,配置成功,但使用网页测试工具传送文本消息,显示请求失败,controller为siteController, action为actionWeixin, 调用url为(http://example.com/web/index.php?r=site/weixin)
在controller中是这么调用的
public function actionWeixin()
{
Yii::$app->weixinMessage->valid();
Yii::$app->weixinMessage->responseMsgs();
}
本人发现,假如不MVC框架,直接把代码放在网站根目录下,直接访问(例如 http://example.com/weixin.php),使用网页调试工具,文本消息,请求成功,并且正确返回数据。代码如下。
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();
$wechatObj->responseMsgs();
class wechatCallbackapiTest
{
public function valid()
{
$echoStr = $_GET["echostr"];
if($this->checkSignature()){
echo $echoStr;
exit;
}
}
public function responseMsgs()
{
//get post data, May be due to the different environments
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
the best way is to check the validity of xml by yourself */
libxml_disable_entity_loader(true);
$postObj = simplexml_load_string($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()
{
// you must define TOKEN by yourself
if (!defined("TOKEN")) {
throw new Exception("TOKEN is not defined!");
}
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
// use SORT_STRING rule
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}

应该是跨域访问的问题。把csrf 验证关闭即可

楼上正解。
