Hyper Text Transfer Protocol (HTTP) is a request-response protocol that enables communications between Client machines and Servers. For example, when you search for something on the browser, your PC sends a POST request to the server, which sends back a response. The response contains status information about the sent request and the requested content. ALSO READ: Linux find File using the command-line [8 Different Ways] There are several HTTP methods.

I'm using the "REST Client" extension for Visual Studio Code I'm able to make a GET request with this code: GET https://some.domain.com/search/someuser/somekey?foo=5&bar=1 and it works. Now, I need to make a POST request and pass the foo and bar values as form fields. I tried with: POST https://some.domain.com/search/ Authorization: Basic someuser somekey Content-Type: application/x-www-form-urlencoded 'foo'='5' 'bar'='1' but I'm getting back an error "Missing required parameter foo in the post body" What is the correct syntax for a POST request with REST Client?

My problem: Using the command line tool to curl my localhost server while sending some data along with my POST request is not working. What seems to be causing the error: Imagine something like this • curl -i -X POST -H 'Content-Type: application/json' -d '' http: //localhost/path/to/api So i gave up. Windows seems to messing up with the JSON object sent on POST I ran into the same issue on my win7 x64 laptop and was able to get it working using the curl release that is labeled C:\Projects\curl-7.23.1-win64-ssl-sspi>curl -H "Content-Type: application/json" -X POST http://localhost/someapi -d "" Which only differs from your 2nd escape version by using double-quotes around the escaped ones and the header parameter value. Definitely prefer the linux shell syntax more. Another Alternative for the command line that is easier than fighting with quotation marks is to put the json into a file, and use the @ prefix of curl parameters, e.g. with the following in json.txt: then in my case I issue: curl localhost:9000/sync -H "Content-type:application/json" -X POST -d @json.txt Keeps the json more readable too. Alternative solution: A More Userfriendly solution than command line: If you are looking for a user friendly way to send and request data using HTTP Methods other than simple GET's probably you are looking for a chrome extention just like this one AVANCED REST CLIENT For guys looking to stay with command-line i recommend cygwin: I ended up installing cygwin with CURL which all...
