Question

I have created a very simple controller for a REST services using the Spring Framework. I have no problems using the @PathVariable in conjunction with GETs but when I try to create a POST or PUT, I am unable to curl the function and am trying to figure out where I have gone wrong.

@Controller
public class TestController {


    @RequestMapping(value = "/test", method = RequestMethod.POST)
    @ResponseBody
    public String putName(@RequestParam("name") String name, @RequestParam("value") String value) {

        System.out.println("Name - " + name);
        System.out.println("Value - " + value);


        return "You entered " + name + " with value of " + value;
    }
}

Editing this a bit to include some PHP since that is ultimately where I want to be calling this from.

If I do the following, it works as expected:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://localhost:8080/RestService/test');
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
    curl_setopt($ch, CURLOPT_TIMEOUT, 120);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'name=some random name&value=just a value');
    $result = curl_exec($ch);

But if I try to pass the parameters as an array, I receive an HTTP Status 400 -The request sent by the client was syntactically incorrect.

    $data = array
    (
        'name' => 'some random name',
        'value' => 'just a value'
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://localhost:8080/RestService/test');
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
    curl_setopt($ch, CURLOPT_TIMEOUT, 120);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $result2 = curl_exec($ch);

If I can at all help it, I do not want to be building strings, worrying about escaping ampersands, and etc out of the data I want to pass.

Any help is greatly appreciated.

Use http_build_query

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
