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. Please note that httpc normalizes input URIs before internal processing and special care shall be taken when the URI has percent ("%") characters. A percent serves as the indicator for percent-encoded octets and it must be percent-encoded as "%25" for that octet to be used as data within the URI. Hi I'm new to Erlang so please forgive my ignorance. I'm trying to stream data from a REST API using httpc, and although I have scoured the internet and the documentation I can't find a good example of how to do this, in particular how the "sync" and "receiver" options interoperate.

Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz; Latency between the two servers < 1 ms; Erlang 20.2; Results "" in erlang is char list while in elixir is ''("" in elixir is binary) you can use :httpc.request('http://www.erlang.org') shortly 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?
A percent serves as the indicator for percent-encoded octets and it must be percent-encoded as "%25" for that octet to be used as data within the URI. The httpc module is part of the standard Erlang distribution and does not have to be installed separately. The first thing to do before using the httpc module is to start the inets service by calling inets:start() or application:start(inets).
You can find how to use in docs. I’ll show you small example of get HTTP request: erlang的httpc模块提供了HTTP的API，在使用之前记得启动inets，如果要使用https，需要启动ssl。 使用request函数来向制定地址发送HTTP消息。 Firefox and Safari behave different from HTTPC. When a webserver responses with 302, the client gets a new location to redirect the request to.

SSL essentially does two things at once: encrypts the data and checks if client and/or server are who they say they are. The latter is where certificate verification comes into play, the encryption part is always done and usually automatically negotiated between client and server. [httpc] Clients started stand-alone not properly handled. Also it was not documented how to use them, that is that once started, they are represented by a pid() and not by their profile().

Dear All I am using httpc to access a web server over https. From reading the erlang ssl docs, this looks like the right way to do it: Url = erlang httpc request timeout 问题. 2021年02月13日 阅读数：23 这篇文章主要向大家介绍erlang httpc request timeout 问题.,主要内容包括基础应用、实用技巧、原理机制等方面，希望对大家有所帮助。 Connecting to Cloudant from Erlang: a quick example of using HTTPS from httpc:request with 2 comments Wiser heads than me will no doubt already know this but I for one struggled with working out how to do this so I thought I’d put the example up in the hope it will help others. The callback is made by a middleman process, hence the file transfer will not be affected by the code in the progress callback function. If the callback should crash this will be detected by the ftp connection process that will print an info-report and then go one as if the progress option was set to ignore. 2020年6月10日 erlang HTTP 客户端使用实例HTTPC的请求范式HTTPC(Method(),Request(), Httoptions().Options()) 2015年4月29日 erlang 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. It is obvious: because Erlang/OTP has HTTP client included!
