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

When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V

On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A

Go language development mobile application tutorial As the mobile application market continues to boom, more and more developers are beginning to explore how to use Go language to develop mobile applications. As a simple and efficient programming language, Go language has also shown strong potential in mobile application development. This article will introduce in detail how to use Go language to develop mobile applications, and attach specific code examples to help readers get started quickly and start developing their own mobile applications. 1. Preparation Before starting, we need to prepare the development environment and tools. head

As a fast and efficient programming language, Go language is widely popular in the field of back-end development. However, few people associate Go language with front-end development. In fact, using Go language for front-end development can not only improve efficiency, but also bring new horizons to developers. This article will explore the possibility of using the Go language for front-end development and provide specific code examples to help readers better understand this area. In traditional front-end development, JavaScript, HTML, and CSS are often used to build user interfaces

Android development is a busy and exciting job, and choosing a suitable Linux distribution for development is particularly important. Among the many Linux distributions, which one is most suitable for Android development? This article will explore this issue from several aspects and give specific code examples. First, let’s take a look at several currently popular Linux distributions: Ubuntu, Fedora, Debian, CentOS, etc. They all have their own advantages and characteristics.

Introduction to PHP interface and how it is defined. PHP is an open source scripting language widely used in Web development. It is flexible, simple, and powerful. In PHP, an interface is a tool that defines common methods between multiple classes, achieving polymorphism and making code more flexible and reusable. This article will introduce the concept of PHP interfaces and how to define them, and provide specific code examples to demonstrate their usage. 1. PHP interface concept Interface plays an important role in object-oriented programming, defining the class application

Interfaces and abstract classes are used in design patterns for decoupling and extensibility. Interfaces define method signatures, abstract classes provide partial implementation, and subclasses must implement unimplemented methods. In the strategy pattern, the interface is used to define the algorithm, and the abstract class or concrete class provides the implementation, allowing dynamic switching of algorithms. In the observer pattern, interfaces are used to define observer behavior, and abstract or concrete classes are used to subscribe and publish notifications. In the adapter pattern, interfaces are used to adapt existing classes. Abstract classes or concrete classes can implement compatible interfaces, allowing interaction with original code.
