erlang

I have an erlang application and it needs to connect to a php application hosted on Apache with HTTPS. How do I install the client certificate on my erlang machine? The SSL module of Erlang/OTP which is the interface for Secure Socket Layer has an option for defining client side certificate: {cacertfile, path()} Path to a file containing PEM-encoded CA certificates. The CA certificates are used during server authentication and when building the client certificate chain. Now if you want to use an HTTP client with the support of client side ssl certificate instead of writing everything by

I have implemented a simple appmod that handle WebSockets and echo back the messages. But how do I handle an ws.close(); from the JavaScript client? I have tried with the code below, but handle_message({close, Reason}) is never called and ws.onclose = function(evt) {} is never executed on the JavaScript client. When I use the same JavaScript client code interacting with a node.js websocket, the client receives an onclose event immediately after ws.close(); . Here is the code for my simple appmod : -module(mywebsocket). -export([handle_message/1]). handle_message({text, Message}) -> {reply,

e.g. I save the tuple T = {k1, v1, k2, v2} to the redis by jedis: eredis:q(Conn, ["SET", <<"mykey">>, term_to_binary(T)]). I am trying to use the code below to read this erlang term: Jedis j = Redis.pool.getResource(); byte[] t = j.get("mykey").getBytes(); OtpInputStream ois = new OtpInputStream(t); System.out.println(OtpErlangObject.decode(ois)); The error is: com.ericsson.otp.erlang.OtpErlangDecodeException: Uknown data type: 239. So how can I get the erlang term correctly? Erlang side: term_to_binary({k1, v1, k2, v2}). <<131,104,4,100,0,2,107,49,100,0,2,118,49,100,0,2,107,50, 100,0,2,118,50

For my application, I'm importing the calendar event from google calendar. The only problem which I'm facing is Time zone list. I'm getting the timezone as output from google calendar xml, which I have to check with time zone list and add time accordingly... so from where I can get this standard time zone list.. or some other alternative to achieve the same. If you're using Java, use Joda Time - the time zone ID given by Google Calendar will be one the Joda Time understands. The standard TimeZone class may well understand it too, but I think Joda is more likely to. Assuming you're seeing all

1.下载安装包 wget http://erlang.org/download/otp_src_22.1.tar.gz 2.解压 tar -xzvf otp_src_22.1.tar.gz 3.cd otp_src_22.1 4.创建安装目录 mkdir /opt/erlang_22.1 5. 配置 ./configure --prefix=/opt/erlang_22.1 6.关注 APPLICATIONS DISABLED ,其他可忽略 7.若使用c++编译则可以忽略jinterface:No java compiler found 8.yum -y install ncurses-devel 9.yum -y install openssl 10.yum -y install openssl-devel 11.yum -y install unixODBC-devel 12.重新配置 ./configure --prefix=/opt/erlang_22.1 或 ./configure --prefix=/opt/erlang_22.1 --without-javac 13.安装 make && make install 14. 配置环境变量 vim /etc/profile 在最后新加一行 export PATH=$PATH:/opt/erlang_22.1/bin 退出，
