You tin purpose either curl or wget ascendancy to mail HTTP requests from UNIX or Linux operating system. Both commands allow y'all to mail GET together with POST requests, which agency y'all tin too telephone phone REST spider web services. I bring a Java spider web application, which runs on Linux together with exposes WebServices. I was writing a UNIX script to download In unopen to information from that spider web service when I hitting past times the question, how produce I brand an HTTP telephone phone from UNIX? What is the UNIX ascendancy should I use? If y'all are too facing the same problem, thus y'all bring come upward to the correct ht place. Basically, y'all tin purpose 2 UNIX commands to brand the HTTP request, wget, together with curl.
You tin purpose whorl together with wget to mail both GET together with POST HTTP requests. My purpose instance was rather simple, I but require to brand a GET telephone phone to spider web service to download the data, but these 2 commands are mighty together with render many unlike options to interact amongst the spider web using HTTP correct from the shell.
Between wget together with curl (also known every bit cURL), whorl (I telephone phone it "karl") is my favorite. Why? I cry back because I bring used it to a greater extent than oftentimes than wget :-).
You tin brand your choices if y'all bring proficient cognition of the Linux ascendancy line, together with that's why I advise every programmer together with software developer join Learn Linux inward v Days together with Level Up Your Career course on Udemy, the best way to leave of absence efficient inward Linux.
Now let's meet how to mail HTTP requests from UNIX using the whorl command.
You tin too specify timeout using -m alternative every bit shown below:
This asking volition timeout inward 2 seconds if it doesn't have whatever response.
You tin too purpose wget to mail HTTP requests together with download the data. The exclusively divergence betwixt curl together with wget is that curl volition impress output inward console together with wget volition shop it inward the file e.g.
volition download the content of index.html together with shop it into a file amongst the same name.
Here is how y'all tin purpose whorl to download wget ascendancy inward UNIX:
