【linux】"CURLE_SSL_CONNECT_ERROR (35)"错误寻求解决方法
使用手册对这个错误值的解释是这样的:
CURLE_SSL_CONNECT_ERROR (35)A problem occured somewhere in the SSL/TLS handshake. You really want
the error buffer and read the message there as it pinpoints the problem
slightly more. Could be certificates (file formats, paths, permissions),
passwords, and others.
主要有如下一些问题:
- 对于排查这个错误有什么建议?
- 如果曾遇到过这样的问题,最后又是怎么解决的?
- 以上所指的paths,默认值是哪个路径,如果要修改的话,怎么修改?
想迫切了解一下第三点,因为所使用的嵌入式文件系统为只读,如果牵扯到修改文件之类的,那必然是失败的。(备注:这一问我从Meteor处得到了答案,CApath: /etc/ssl/certs
是Linux环境下的默认路径)在哪个源文件可以更改这个默认的配置路径?(这里有更改CApath路径的接口介绍)
ssl连接的时候,又出现了状况:
* error:10067066:elliptic curve routines:ec_GFp_simple_oct2point:invalid encoding

回答
傻乎乎的去跟踪代码,结果发现是编译openssl的方法不正确!
这里面可以包括被GFW墙掉的吧.
比如Facebook
PS C:\Users\meteor> curl -v https://www.facebook.com* About to connect() to www.facebook.com port 443 (#0)
* Trying 31.13.64.129... connected
* Connected to www.facebook.com (31.13.64.129) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: C:\Windows\system32\curl-ca-bundle.crt
CApath: none
* Unknown SSL protocol error in connection to www.facebook.com:443
* Closing connection #0
