从sharepoint托管应用调用WCF服务： [英] calling a WCF service from a sharepoint hosted app :

问题描述

我正在尝试使用REST api从sharepoint托管应用程序调用WCF服务。如果我在浏览器的seprate选项卡中点击url工作正常。但是当我在sharepoint托管app中使用相同的代码时，我面临跨域问题。下面是控制台输出
i在浏览器中获取。

I am trying to call a WCF service from sharepoint hosted app using REST api. If i hit the url in a seprate tab of the browser that works fine. But when i use same code inside a sharepoint hosted app i face cross domain issue. below is the console output i gets in browser.

OPTIONS http：// depmsag-sp2013：8888 / _vti_bin / MyService / MyService.svc / CreateSalesRecord / 1/2 

OPTIONS http://depmsag-sp2013:8888/_vti_bin/MyService/MyService.svc/CreateSalesRecord/1/2  

jquery-1.10.2.min.js：23

XMLHttpRequest无法加载http：// depmsag- sp2013：8888 / _vti_bin /为MyService / MyService.svc / CreateSalesRecord / 1/2。请求的资源上不存在"Access-Control-Allow-Origin"标头。 Origin'http：//apps-aee12a2dd34954.msagapps.nagintranet.com:8888'是
因此不允许访问。响应的HTTP状态代码为401. 

jquery-1.10.2.min.js:23
XMLHttpRequest cannot load http://depmsag-sp2013:8888/_vti_bin/MyService/MyService.svc/CreateSalesRecord/1/2. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://apps-aee12a2dd34954.msagapps.nagintranet.com:8888' is therefore not allowed access. The response had HTTP status code 401. 

如果可能，请指导我一些帮助。

sanjay ，如果你正在使用jQuery请求，请使用
jsonp 给您的客户请求能够到达它。
Sample ：

joshi sanjay, if you are using jQuery for requests, use jsonp to your client request be able to reach it. Sample:

/* Loading JSON objects using JSONP */
(function(

）{
var url ='http：//www.jquery4u.com/scripts/jquery4u.settings。 json';

) { var url = 'http://www.jquery4u.com/scripts/jquery4u.settings.json';

.ajax（{
type：'GET'，
url：url，
async：false，
contentType： "application / json"，
dataType：'jsonp'
}）;
}）（jQuery）;

.ajax({ type: 'GET', url: url, async: false, contentType: "application/json", dataType: 'jsonp' }); })(jQuery);

和你的服务器正在接收请求（WCF服务应用程序）应该也能够处理跨域请求，为此考虑在web.config上启用它。

And your server that are receiving the request (WCF Service Application) should be able to process cross domain requests too, for this considering enable it on web.config

<configuration>
 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="*" />
     </customHeaders>
   </httpProtocol>
 </system.webServer>
</configuration>
