我正在尝试学习宁静的Web服务Post逻辑。 为了测试Post逻辑，我使用jQuery来调用restful API。
我用于下面提到的测试的代码。 宁静的API代码。
package com.crunchify.tutorials;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.codehaus.jettison.json.JSONObject;
@Path("/")
public class CrunchifyRESTService {
@POST
@Path("/verify")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public RestBean MsgRsc(RestBean message) {
System.out.println(message.id1);
return message;
}
RestBean class.
package com.crunchify.tutorials;
import org.codehaus.jackson.annotate.JsonProperty;
public class RestBean {
@JsonProperty("param1")
int id1;
@JsonProperty("param2")
int id2;
}
Jquery客户端。
<html>
<head>
<script type="text/javascript" src="js/jquery.1.7.2.js"></script>
<script type="text/javascript" src="js/jquery.jsonview.js"></script>
<link rel="stylesheet" href="css/jquery.jsonview.css" type="text/css"/>
<script type="text/javascript">
function testWebservice(){
var url = "http://localhost:8081/TestPost/verify";
var params = {param1:1,param2:2};
var jsonParam = JSON.stringify( params );
$.ajax( {
type: "POST",
url: url,
dataType: "json",
contentType: "application/json",
success: function(response){
$("#responseContent").JSONView(response);
console.log("Success");
},
error: function( jqXHR, textStatus, errorThrown ){
console.log("Failed");
}
} );
}
</script>
</head>
<div style="margin:20px 0 0 20px;">
<input type="button" value="Test" id="a2" onclick="testWebservice()"/>
</div>
<div id="responseContent" style="border: 1px solid #ccc;height: 500px;overflow: scroll;width: 500px; margin: 20px 0 0 20px;">
</div>
</html>
当我使用jQuery客户端测试时，我收到以下错误。不知道如何解决它。
