How To Post Http Asking From Unix Or Linux? Purpose Curlicue Or Wget Command

You tin transportation away purpose either curl or wget ascendence to transportation HTTP asking from UNIX or Linux operating system. Both commands allow you lot to transportation GET too POST request, which way you lot tin transportation away too telephone telephone REST spider web services.  I bring a Java spider web application, which runs on Linux too exposes WebServices. I was writing a UNIX script to download In to a greater extent than or less information from that spider web service when I hitting yesteryear the question, how produce I brand an HTTP telephone telephone from UNIX? What is the UNIX ascendence should I use? If you lot are too facing the same question, too then you lot bring come upwards to correct place. Basically, you lot tin transportation away purpose 2 UNIX commands to brand the HTTP request, wget, too curl. You tin transportation away purpose whorl too wget to transportation both GET too POST HTTP request. My purpose instance was rather simple, I only ask to brand a GET telephone telephone to spider web service to download the data, but these 2 commands are really powerful too render many dissimilar options to interact amongst the spider web using HTTP correct from the shell.

Between wget too curl (also known equally cURL), whorl (I telephone telephone it "karl") is my favorite. Why? I think because I bring used it to a greater extent than oftentimes than wget :-). You tin transportation away brand your choices if you lot bring skilful noesis of Linux ascendence trouble too that's why I propose every Java developer to read The Linux Command Line: H5N1 Complete Reference, the best way to give-up the ghost efficient inwards Linux. Now let's meet how to transportation HTTP asking from UNIX using  the whorl command.

UNIX ascendence to transportation HTTP GET request

Here is i instance of calling spider web service from Linux crunch yesteryear sending HTTP GET request using cURL command:

$ whorl http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=bd82977b86bf27fb59a04b61b657fb6f {"coord":{"lon":-0.13,"lat":51.51},"weather":[{"id":804,"main":"Clouds","description":"overcast clouds","icon":"04n"}],"base":"stations","main":{"temp":282,"pressure":1022,"humidity":87,"temp_min":277.15,"temp_max":285.15},"visibility":10000,"wind":{"speed":1.5},"clouds":{"all":90},"dt":1445577409,"sys":{"type":1,"id":5093,"message":0.0201,"country":"GB","sunrise":1445582275,"sunset":1445619056},"id":2643743,"name":"London","cod":200} 

You tin transportation away too specify timeout using -m choice equally shown below:

$ whorl -m 2 http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=bd82977b86bf27fb59a04b61b657fb6f

This asking volition timeout inwards 2 seconds if it doesn't have whatsoever response.

You tin transportation away too purpose wget to transportation HTTP asking too download the data. Only departure betwixt curl too wget is that curl volition impress output inwards console too wget volition shop it inwards the file e.g.

$ wget http://localhost:8080/index.html

volition download the content of index.html too shop into a file amongst the same name.

Here is how you lot tin transportation away purpose whorl to download wget ascendence inwards UNIX:

UNIX ascendence to transportation HTTP POST request

You tin transportation away too purpose whorl to transportation HTTP postal service request. All you lot ask to produce is purpose the --data choice to specify the information you lot desire to POST to spider web service e.g.

$ curl --data "param1=value1&param2=value2" http://locahost:8080/weather

if you lot desire to transportation a information from file to spider web service, you lot tin transportation away too purpose the next command:

$ whorl -X POST -d @filename http://locahost:8080/weather

Similarly, if you lot desire to upload a file you lot tin transportation away produce thus yesteryear executing the next command:

$ whorl --form "fileupload=@filename.txt" http://locahost:8080/weather

That's all nearly how to transportation HTTP asking from UNIX too Linux. It's simple, only retrieve whorl too wget command. you lot tin transportation away explore their choice yesteryear using human being wget too human being curl. Also, retrieve the departure betwixt whorl too wget, erstwhile prints the output inwards the console spell later on shop the response inwards the same file equally requested. I personally similar whorl because it's easier to purpose but if you lot similar wget stick amongst it.
