certificate unknown(46)

因为腾讯云的网站备案迟迟没有批下来，因此使用了朋友在阿里云的域名yk，我则申请了一台阿里云服务器，并将域名解析映射至该服务器。SSL证书则是在腾讯云上申请的，使用了Apache文件夹中的文件，放置在cowboy的priv/ssl目录下，1_root_bundle为根证书，2_yk.crt为网站证书，3_yk.key为密钥。一切布置妥当后，在PC的chrome、android的chrome、苹果手机的微信等环境中均可以正常访问，但是在android的微信中访问时服务器报如下错误： client alert Fatal: unknown certificate(46) RFC中的解释是： certificate_unknown Some other (unspecified) issue arose in processing the certificate, rendering it unacceptable. 搜索到一些信息，如： https://cweiske.de/tagebuch/https-client-cert-unknown.htm 也使用wireshark抓包排查了流程，但是由于对SSL不是非常了解，始终没有找到进一步的原因和方向。后来向一些朋友请教，整理了思路。对于这种问题，首先要到SSL测试网站上测试具体的问题： https://www.myssl.cn

Issue when registering two local process with gproc within cowboy websocket handler

communicating between http handler and websocket handler in Cowboy

由 白昼怎懂夜的黑 提交于 2019-12-23 11:57:43
问题 I'd like to create a websocket app in Cowboy that gets its data from another Cowboy handler. Let's say that I want to combine the Echo_get example from cowboy: https://github.com/ninenines/cowboy/tree/master/examples/echo_get/src with websocket example https://github.com/ninenines/cowboy/tree/master/examples/websocket/src in such a way that a GET request to Echo should send a "push" via websocket handler to the html page in that example. What is the least complicated way to do it? Can I use

Shouldn't it be after plug :dispatch ? Do I need to define an additional route With this declaration:

Facing intermittent 404 issue when calling Rails API

问题 I have banged my head on this for 2 days now and i dint find any luck yet. Looking for help on this. The issue: Front End makes 10 similar XHR requests ( for different users ) to my Rails API and few of the requests randomly fails with 404 status code. My Observations: If i make the same request again, It passes. I dont see any trace of 404 requests even hitting my server ( using logs ). I do see different response headers for 200 and 404 ( mentioned below ) and i see cowboy ( https://github
