- use the http protocol
- use web_custom_request
- specify in web_custom_request the appropriate REST method:
- Method=PUT
- Method=GET
- Method=DELETE
The following script gives an example of this method in the case of REST PUT request using a JSON request message. (XML request message would be similar). One of the fields in the message is parameterized using a random number parameter. The parameter is given a format of "0000000000000000000000%09lu" to achieve a 32 character-long number string.

char *request_json_base;

// save web service url to param {URL}
char *URL = "http://SERVER:8080/Path";
lr_save_string(URL, "URL_Param");
// save json request to param {REQUEST_JSON_PARAM}, parameterize "SomeID" as random number
request_json_base=
"{"
" \"Field1\" : \"ValueOfField1\","
" \"SomeID\" : \"{SomeID}\","
" \"Field2\" : \"ValueOfField2\","
" \"Field3\" : \"ValueOfField3\","
"}";
request_json = lr_eval_string(request_json_base);
lr_save_string(request_json, "REQUEST_JSON_PARAM");
// set http headers
web_add_header("Content-Type", "application/json; charset=utf-8");
// validate response
