如何在ajax中调用跨域asmx Web服务。如何允许从ajax中的其他域调用Web服务 [英] how to call a cross domain asmx web service in ajax . how to allow a web service to be callable from other domain in ajax
问题描述
你好朋友......我正在尝试从这么多天来从javascript调用一个web服务...这在另一个域上可用...意味着跨域Web服务。我一次又一次地失败，任何人都可以告诉我如何以富有成效的方式做到这一点。
1：服务是这样的..
[WebService（Namespace =" http： //tempuri.org/"）]
[WebServiceBinding（ConformsTo = WsiProfiles.BasicProfile1_1）]
//允许从脚本调用此Web服务，使用ASP.NET AJAX，取消注释以下行。
[System.Web.Script.Services.ScriptService]
公共类阵营：System.Web.Services.WebService {< br $>
公共营地（）{
//如果使用设计组件，请取消注释以下行
// InitializeComponent（）;
}
[WebMethod，ScriptMethod（ResponseFormat = ResponseFormat.Json，UseHttpGet = true） ]
public string HelloWorld（）{
return" Hello World ... it cross domain";
}
}
2：和脚本功能是这样的....
< script type =text / javascript>
$（文件）.ready（function（）{
var surl =http：// localhost ：1061 / camp_web_service / camp.asmx / HelloWorldcallback = hello;
$ .ajax（{
类型：'GET'，
url ：surl，
crossDomain：true，
contentType：application / json; charset = utf-8，
dataType：jsonp，
成功：函数（msg）{
$ .each（msg，function（name，value）{
alert（value）;
}）;
}，
错误：函数（xhr，状态，错误）{alert（'Servidor de error 404 !!'）;}，
async：true，
cache：false
}）;
}）;
< / script>
hello friends... i am trying from so many days to call a web service from javascript... which is available on another domain... means cross domain web service . and i am failing again and again , can anyone tell me how to do it in productive way.
1: the service is like this ..
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class camp : System.Web.Services.WebService {
public camp () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = true)]
public string HelloWorld() {
return "Hello World... its cross domain";
}
}
2: and script function is like this ....
<script type="text/javascript">
$(document).ready(function () {
var surl = "http://localhost:1061/camp_web_service/camp.asmx/HelloWorldcallback=hello";
$.ajax({
type: 'GET',
url: surl,
crossDomain: true,
contentType: "application/json; charset=utf-8",
dataType: "jsonp",
success: function (msg) {
$.each(msg, function (name, value) {
alert(value);
});
},
error: function (xhr, status, error) { alert('Servidor de error 404 !!'); },
async: true,
cache: false
});
});
</script>
推荐答案
（document）.ready（function（）{
var surl =http：// localhost：1061 / camp_web_service / camp.asmx / HelloWorldcallback = hello;
(document).ready(function () {
var surl = "http://localhost:1061/camp_web_service/camp.asmx/HelloWorldcallback=hello";
.ajax（{
类型：'GET'，
url：surl ，
crossDomain：true，
con tentType：application / json; charset = utf-8，
dataType：jsonp，
成功：函数（msg）{
.ajax({
type: 'GET',
url: surl,
crossDomain: true,
contentType: "application/json; charset=utf-8",
dataType: "jsonp",
success: function (msg) {
.each（msg，function（name，value）{
alert（value）;
}）;
}，
错误：函数（xhr，状态，错误）{alert（'Servidor de error 404 !!'）;}，
async：true，
缓存：false
}）;
}）;
< / script>
.each(msg, function (name, value) {
alert(value);
});
},
error: function (xhr, status, error) { alert('Servidor de error 404 !!'); },
async: true,
cache: false
});
});
</script>
