erlang HTTP 客户端使用实例 HTTPC的请求范式 HTTPC(Method(),Request(),Httoptions().Options()) 其中 Method=head|

Regards -- You received this message because you are subscribed to the Google Groups "Erlang Programming" group. Firefox and Safari behave different from HTTPC. When a webserver responses with 302, the client gets a new location to redirect the request to. The httpc server has autoredirect by default set to true and following the redirects is expected. While using an industrial web service, I used httpc to follow a link that was redirected.

Erlang httpc

This did not work. Erlang atoms like database become :database and a local variable like PgConn in the Erlang version becomes pg_conn in Elixir. We need to single-quote string literals when they are arguments to an Erlang function. What is Erlang? Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance.

Here is the only example being via erl -config inets.config that looks like this: [{inets, [{services,[{httpc,[{profile, summary I found that HTTP client occasionally has a very long timeout.

Other profiles can also be started at application startup, or profiles can be started and stopped dynamically in runtime. I found that HTTP client occasionally has a very long timeout. So I dig deep into the timeout of Erlang httpc.

[4] Yaws logs show no abnormal activities when "httpc" services on the client receive sockets failures, except for information on reaching the maximum number of files in cache. [5] I have raised the number of processes to 500000 using +P only on the client side ERTS. _____ erlang-questions mailing list erlang-q@erlang.org

On my local system, the code is working fine, but if I execute the call from an erlang file of the ejabberd server, I get a bad argument The httpc module does not handle the "max" parameter of the "keep-alive" in the http protocol. The reason is that when a httpc_handle process is reach the max times of the "keep-alive:max", then server will close the connect, but httpc_manager also select this httpc_handler(because it is alive, and will append to its http request queue) to send http request, so the requester will receive the The gen_server is very simple, it uses erlang:send_after/3 to send itself a "poll" message. Upon receiving this poll message, if not paused, it hits a url and saves the response to an ETS and fires off another erlang:send_after/3 to poll again after an appropriate interval. But I am having a hard time finding an example of posting data to an ssl endpoint via erlang. Does anybody know of a simple example that I am missing? I think I figured it out.
