C# .NET 微信开发-------当微信服务器推送消息时如何接收处理
最近一直在看微信,整整一个月了,看到现在说实话还有很多没看的,从前两周一点看不懂到现在单个功能的一步步实现,不知道这样的速度是否太慢了。
不过现在往下看还是有思路了,目前整个文档完成学习只有1/3左右,但是看过的每个接口都是测试过的。学习很重要,但是有人指引将会效率翻倍,但是谁会愿意无偿花自己的时间给你呢,所以嘛。。。就不说了,
好了,牢骚到此,对于我这篇文章有什么不明白的或者需要交流的请加 QQ群:216390234
首先来门要有思路对吧,我们不是流水线的工人,而是系统的创造者,所以我们要有思想而不是一味的写代码,写到最后发现哪哪都不合适然后去修改,发现修改的时间远远大于开发的时间,那样就徒劳了。
这篇很简单适用于刚刚入门的开发者:
对于微信的基本配置我就不阐述了,网上讲解的很详细了。
1、项目:MVC(不是api)
2、
