https://developers.weixin.qq.com/miniprogram/dev/platform-capabilities/industry/express/business/intracity_service.html 现在的鄙视链都已经这么严重了嘛？同样签名，同样的请求头部，同样的参数。使用NodeJS 的 axios 请求库，可以正常返回。但是在C#中使用HttpClient 却显示签名错误。 为了验证正确性，我都怀疑是我这个写了多年C# 代码的程序员出现了问题，特意的使用 PostMan/ApiPost 进行了测试，断点将 NodeJS 发送的数据和请求头部，全部放入 PostMan/ApiPost 进行了发送请求测试。结果还是得到的这一串： {"errcode":40234,"errmsg":"invalid signature rid: 653249ef-2760901b-3a1f8f59"} OK，OK，OK，说到这里可能并不会有人相信我，现在我就来丢一串视频文件，并且附带两个请求的相关数据。 OK，OK，OK。除了腾讯视频，不支持我上传视频文件是吧？？？可以，我不上传了，考虑太多因素，本身是想上传服务器的，但是生产服务器，又不敢上传，所以，需要视频的，可以加我微信，我提供给你。 如果官方 需要视频，请及时联系我 微信号：F132951 微信名：小方 放一些参数把，这个是NodeJS 的参数（第一次发现问题保存的） {   status: 200,   statusText: "OK",

看到了嘛？参数一样，返回的结果不一样，我还有一段12分钟长的视频证据，所以，到底是什么问题呢？？？ 希望可以尽快的得到一个满意的答复！
