- 微信公众号消息加解密为何在验签时失败？
我们需要在公众号中对收发的消息进行加密，在公众号中设置了兼容模式进行调试，根据文档https://developers.weixin.qq.com/doc/offiaccount/Message_Management/Message_encryption_and_decryption_instructions.html下载了demo，demo可以正常运行，但是如果把其中的参数改成我们公众号自己的参数，解密时在验签步骤就失败了，代码运行后得到的signature和附带的signature不一样，导致验签失败。 我们使用的语言是C#，原本的代码如下： //公众平台上开发者设置的token, appID, EncodingAESKey string sToken = "QDG6eK"; string sAppID = "wx5823bf96d3bd56c7"; string sEncodingAESKey = "jWmYm7qr5nMoAUwZRjGtBxmz3KA1tkAj3ykkR6q2B2C"; Tencent.WXBizMsgCrypt wxcpt = new Tencent.WXBizMsgCrypt(sToken, sEncodingAESKey, sAppID); /* 1. 对用户回复的数据进行解密。 * 用户回复消息或者点击事件响应时，企业会收到回调消息，假设企业收到的推送消息： * POST /cgi-bin/wxpush? msg_signature=477715d11cdb4164915debcba66cb864d751f3e6×tamp=1409659813&nonce=1372623149 HTTP/1.1 Host: qy.weixin.qq.com Content-Length: 613 * * */ string sReqMsgSig = "477715d11cdb4164915debcba66cb864d751f3e6"; string sReqTimeStamp = "1409659813"; string sReqNonce = "1372623149"; string sReqData = ""; string sMsg = ""; //解析之后的明文 int ret = 0; ret = wxcpt.DecryptMsg(sReqMsgSig, sReqTimeStamp, sReqNonce, sReqData, ref sMsg); if (ret != 0) { System.Console.WriteLine("ERR: Decrypt fail, ret: " + ret); return; } System.Console.WriteLine(sMsg); 当把其中的参数sToken，sAppID，sEncodingAESKey，sReqMsgSig，sReqTimeStamp，sReqNonce，sReqData替换成真实推送过来的参数，验签步骤就失败了，失败的原因是代码生成的signature和传递过来的signature不一致 ret = VerifySignature(m_sToken, sTimeStamp, sNonce, sEncryptMsg, sMsgSignature); private static int VerifySignature(string sToken, string sTimeStamp, string sNonce, string sMsgEncrypt, string sSigture) { string hash = ""; int ret = 0; ret = GenarateSinature(sToken, sTimeStamp, sNonce, sMsgEncrypt, ref hash); if (ret != 0) return ret; //System.Console.WriteLine(hash); if (hash == sSigture) return 0; else { return (int)WXBizMsgCryptErrorCode.WXBizMsgCrypt_ValidateSignature_Error; } } 返回的ret结果是-40001，尝试过sToken使用token的名称或者最新的值，都在验签步骤失败，一样的错误。 [图片] 根据文档https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/Before_Develop/Technical_Plan.html，消息解密需要用到的数据有timestamp, nonce, msg_signature(来自request.querystring), Encrypt Message(来自Request.InputStream中的密文消息体Encrypt节点), Token(微信开放平台上，服务方设置的接收消息的校验 token)。 验签时根据Token, timestamp, nonce, Encrypt生成signature, 和msg_signature比对完成验签。 请问问题出在哪里？是哪个参数没有设置好？ 已解决，是Token参数使用错了，用的是AccessToken，导致生成的签名不一致，使用公众号中设置的Token名称即可。
04-08 - 微信公众号被动消息不回复怎么解决？
在微信公众号里启用了服务器配置，当用户关注/发送消息时，可以正常接收到微信服务器推送的消息，但当解析处理结束完，最后给微信服务器发送的消息没有出现在公众号里。 收到的推送消息如下(ToUserName, FromUserName, MsgId, Encrypt已改成xxxxxxxxxx): 1702020193 xxxxxxxxxxx 发送的是普通文本消息，通过记录日志可以看到发送前的XML是这样的(ToUserName, FromUserName已改成xxxxxxx)， 638376296547081065 参考文档 https://developers.weixin.qq.com/doc/offiaccount/Message_Management/Passive_user_reply_message.html#0，格式没有问题，from和to的数据也都没有问题，也已经返回给微信服务器了，但就是没有出现在公众号里，也没有任何提示，就好像压根就没有返回要回复的xml，请问这是什么原因造成的？ 一旦遇到以下情况，微信都会在公众号会话中，向用户下发系统提示“该公众号暂时无法提供服务，请稍后再试”： 1、开发者在5秒内未回复任何内容 2、开发者回复了异常数据，比如JSON数据等 如果回复超时了，应该显示提示，可现在的情况是没有提示信息。
2023-12-08 - 调用新建草稿的API，传入的content是html, 为何样式会乱？
根据文档 https://developers.weixin.qq.com/doc/offiaccount/Draft_Box/Add_draft.html content 是图文消息的具体内容，支持HTML标签，必须少于2万字符，小于1M，且此处会去除JS,涉及图片url必须来源 "上传图文消息内的图片获取URL"接口获取。外部图片url将被过滤。 我在调用新建草稿的API时，设置参数content为一段网页的html源码(不包含js)，并将双引号改成单引号(双引号通不过，会报invalid media id的错误)，成功新建了草稿。但当我从微信公众号后台打开这个草稿时，发现样式完全不对。 看文档content是支持html标签的，可为何传入的html显示出来的效果和原网页完全不一样？不是说支持html吗？为何上传后的html和上传前差别这么大？ 上传前html长这样 [图片] 上传到草稿后长这样 [图片] 附html源码 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html><head> <meta http-equiv="Content-Type" content="text/html;

2023-11-16 - 调用微信API创建草稿箱，为什么设置的临时素材无效？
参考文档https://developers.weixin.qq.com/doc/offiaccount/Draft_Box/Add_draft.html 其中参数thumb_media_id是图文消息的封面图片素材id（必须是永久MediaID） 创建新的草稿箱，其中的参数thumb_media_id设置成上传的临时素材id(现在已经不能通过API上传永久素材了，所以这里只能上传临时素材，上传的临时素材在公众号后台又找不到)。 调用API创建草稿箱时报错 错误代码: 40007, 错误信息: invalid media_id hint: [0rXo80521p504] rid: 65533789-61d6f1ca-39da0b94 这个问题该如何解决？如果我没理解错的话，看起来是矛盾的，创建草稿箱必须使用永久素材，而永久素材现在又不能通过API创建。
