ssl - 如何使用 Erlang 进行 HTTPS 请求？

Question

我尝试了inets图书馆，但它超时了。我认为它不支持 HTTPS。我正在尝试使用 ibrowse，但它不起作用。

Answer 1

这对我来说很好：

1> application:start(inets).
ok
2> application:start(ssl).  
ok
3> http:request(head, {"https://example.com", []}, [{ssl,[{verify,0}]}], []).
{ok,{{"HTTP/1.1",200,"OK"},
     [{"cache-control","max-age=0, proxy-revalidate"},
      {"date","Sun, 23 May 2010 00:38:33 GMT"},
      {"server","BAIDA/1.0.0"},
      {"content-type","text/html; charset=windows-1251"},
      {"expires","Sun, 23 May 2010 00:38:33 GMT"},
      {"set-cookie",
       "uid=9041986921274575113; domain=.example.com; path=/; expires=Tue, 19 Jan 2038 03:14:07 GMT"}],
     []}}

http:request("https://example.com")不过也可以，您只需要在任何请求之前加载适当的应用程序。

Answer 2

这对我有用：

application:start(crypto),
application:start(public_key),
application:start(ssl),
application:start(inets).

httpc:request(head, {"https://example.com", []}, [{ssl,[{verify,0}]}], []).

Answer 3

对我来说，这适用于 Erlang/OTP 24 上 Yaws 2.1.0 中的获取请求（启用对等验证）：

application:start(inets).
application:start(crypto).
application:start(asn1).
application:start(public_key).
application:start(ssl).

httpc:request(get, {"https://example.com", []}, 
    [{ssl, [{verify, verify_peer}, {cacertfile,"/path/to/cacertfile.crt"}]}], []).

否则会有警告："Authenticity is not established by certificate path validation"
