Curl GET request with json parameter

Question

I am trying to send a  GET  request to a remote REST API from Command Prompt via cURL like this   curl -X GET -H  Content-type  application json  -H  Accept  application json    http   server 5050 a c getName   param0   pradeep      But it returns no output  I tried to ping the URL directly from the browser  I am able to get response successfully  I don t understand what is the wrong with the command   Basically I want to set a  GET  request to a remote REST service which gives me json data as a response via curl  Can anyone guide me what mistake am I doing  I tried various posts  but all of them talk about POST requests not about GET

If you want to send your data inside the body, then you have to make a POST or PUT instead of GET.

For me, it looks like you're trying to send the query with uri parameters, which is not related to GET, you can also put these parameters on POST, PUT and so on.

The query is an optional part, separated by a question mark ("?"), that contains additional identification information that is not hierarchical in nature. The query string syntax is not generically defined, but it is commonly organized as a sequence of = pairs, with the pairs separated by a semicolon or an ampersand.

For example:

curl http://server:5050/a/c/getName?param0=foo&param1=bar

None of the above mentioned solution worked for me due to some reason  Here is my solution  It s pretty basic      curl -X GET API ENDPOINT -H  Content-Type  application json  -d  JSON DATA    API ENDPOINT is your api endpoint e g  http   127 0 0 1 80 api   -H has been used to added header content   JSON DATA is your request body it can be something like      data key    value         surrounding JSON DATA are important   Anything after -d is the data which you need to send in the GET request

If you really want to submit the GET request with JSON in the body  say for an XHR request and you know the server supports processing the body on GET requests   you can   curl -X GET     -H  Content-type  application json      -H  Accept  application json      -d    param0   pradeep         http   server 5050 a c getName    Most modern web servers accept this type of request

This should work      curl -i -H  Accept  application json   server 5050 a c getName  param0   pradeep      use option -i instead of x

Try  curl -G       instead of  curl -X GET       Normally you don t need this option  All sorts of GET  HEAD  POST and PUT requests are rather invoked by using dedicated command line options   This option only changes the actual word used in the HTTP request  it does not alter the way curl behaves  So for example if you want to make a proper HEAD request  using -X HEAD will not suffice  You need to use the -I  --head option

GET takes name value pairs   Try something like   curl http   server 5050 a c getName  param1 pradeep  or   curl http   server 5050 a c getName param1 pradeep  btw a regular REST should look something like  curl http   server 5050 a c getName pradeep If it takes JSON in GET URL  it s not a standard way
