Hello,

i am using htmlunit with spring test in order to test all ihm interface from my web application. It works fine with html form (post and get) and with ajax get but i have a problem with ajax post request.

The controller don't received the request. If i replace post by get the junit test case works fine.

this the html view

<html lang="fr" xmlns="http://www.w3.org/1999/xhtml"
	xmlns:th="http://www.thymeleaf.org">
	<head>
		<title>Spring Html Unit</title>
        <meta charset="utf-8" />
		<meta name="format-detection" content="telephone=no">

		<script>
			function postTest() {
				$.ajax({
			        type:"post",
					data: {
						'subject' : 'subject test',
						'message' : 'message test'
					},
			        url:"[[@{/test/post}]]",
			        success: function(data, textStatus, jqXHR){
			        	$("#result").text(data);
			        }
			    });
			}
		</script>
	</head>
	<body>
		<h4 th:text="'Hello to Thymeleaf '+${myParam}">Hello from Thymeleaf</h4>
		<button type="button" onClick="postTest()">Test post</button>
		<div>
			<span>result :</span><span id="result"></span>
		</div>
	</body>
</html>

and the controller

@Controller
public class WelcomeController {
	@GetMapping("/")
	public String init(Model model) {
		model.addAttribute("myParam", "Guillaume");
		return "welcome";
	}
	@PostMapping("/test/post")
	public @ResponseBody String post(@RequestParam String subject, @RequestParam String message, Model model) {
		return subject + " " + message;
	}
}

you can also find the complete code on my github https://github.com/guisimon28/spring-test-htmlunit

Can you help me to find if there is some missing configuration or if its a htmlunig bug or pull request ?

Thanks for All

Guillaume
