我在Java的localhost上创建了一个RESTful Web服务。当我在导航器地址栏中输入以下网址时:
http://localhost:8080/GeonotesApp2-war/webresources/route/1
它会给我:
{"rid":"1","routeComment":"hhhahahahah","routeDateCreate":"2012-04-03T00:00:00+02:00","routeDistance":"13400.0","routeName":"route1","routeUserId":"1"}
现在我想使用Ajax调用通过此脚本获取此JSON信息:
<html >
<head>
<meta charset="utf-8">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(function(){
$.ajax({
type: "GET",
url: "http://localhost:8080/GeonotesApp2-war/webresources/route/1",
dataType: 'json',
headers: {
Accept: "application/json",
"Access-Control-Allow-Origin": "*"
},
success: function(resp) {
alert("success");
},
error: function(e) {
alert("error: "+e);
}
});
});
</script>
</head>
<body>
Hello Test Service!
</body>
但是我总是收到错误消息:
error: [object Object]
我找到了这篇文章并完全遵循了它的作用,但是没有用。谁能告诉我为什么?感谢
Calling Rest webservice using JQuery Ajax call , web service is returning JSON string
答案 0 :(得分:4)
标题必须在服务端。因此浏览器知道服务器允许该网站使用Ajax来加载数据。所以这些标题:
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET
