Lisp Flavored Erlang (LFE) is a functional, concurrent, garbage collected, general -purpose (let* ((method 'get) (headers '()) (request-data `#(,url ,headers)) (http- options ()) (request-options '(#(sync false)))) (httpc:re

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.

Have I mentioned data transforms yet? It’s not fun having a database that speaks in json and an application that listens in Erlang. Trials and validations. Input validation made me wonder if I should have asked for a second coffee. erlang http server service start/stop A web server can be configured to start when starting the inets application or started dynamically in runtime by calling the Inets application API inets:start(httpd, ServiceConfig) , or inets:start(httpd, ServiceConfig, How) , see inets(3) Below follows a description of the available configuration options, also called properties.

A full list of bug fixes and improvements in the readme . Download and documentation Erlang HTTP client benchmarks . Contribute to roowe/httpc_bench development by creating an account on GitHub. I tried to use Erlang's httpc module for high concurrent requests. My code for many requests in spawn hasn't worked:-module(t). -compile(export_all).

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?

Module httpc was introduced in OTP R13B04. Description. This module provides the API to an HTTP/1.1 compatible client according

抽奖. erlang httpc. 可以将 HTTP 客户端配置为在启动Inets应用程序或通过调用Inets应用 APIinets:start(httpc, ServiceConfig)或inets:start(httpc, ServiceConfig, How)，见inets(3)配置选项如下： {profile，profile（）} [erlang-questions] socket_closed_remotely errors with httpc jim rosenblum jim.rosenblum@REDACTED Sat Mar 14 04:19:47 CET 2015. Previous message (by thread): [erlang-questions] Announcing Erlang.org Code of Condu Next message (by thread): [erlang-questions] socket_closed_remotely errors with httpc This enables Erlang implementations to interface Microsoft SharePoint and other Microsoft Internet Information Services (IIS) based applications.

Other profiles can also be started at application startup, or profiles can be started and stopped dynamically in runtime. 2) From erlang console start inets application, create callback function for httpc module and start 15 async queries (each 4000 bytes length): inets:start(). F = fun(X) -> io:fwrite( '~p ' , [element(1, X)]) end. Looking for thoughts on the various Erlang HTTP client libraries, for a use case involving, say, 3000-5000 calls per second (from my server, as a client, to HTTP servers). I'm thinking of httpc, Gun, Hackney, any others Performance, reliability, other pros/cons. Involves both GET and POST requests, with a hard roundtrip timeout of ~100 ms. Results are from Erlang 17.2.1.

While using an industrial web service, I used httpc to follow a link that was redirected. 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. Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability.

Description. This module provides the API to an HTTP/1.1 compatible client according to RFC 2616 This is the process id to be used as an argument to httpc:stream_next/1 to trigger the next message to be sent to the calling process.

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. This did not work.

Make sure you have a high nofile limit, and enough sockets (on Ubuntu, sudo sysctl -w net.ipv4.ip_local_port_range="2048 65535"). Terminal 1 It is obvious: because Erlang/OTP has HTTP client included! And you can call it from any Elixir application with easy, using Erlang modules as atoms. This client is called httpc. It’s simple enough, easy usable and don’t require modifications of your mix.exs.
