I am trying to perform a cross domain request from SharePoint hosted add-in to a wcf service in provider hosted add-in.
I have a hybrid setup as below:
- SharePoint Office 365 site online, Azure subscription & other required elements in Azure AD
- A SharePoint hosted Add-in with a custom action and custom page, deployed successfully.
- A provider hosted Add-in which has a wcf RESTfulservice, deployed and published successfully. I see the correct response when requested through browser.
Scenario: On a button click from a SharePoint hosted Add-in page, I would like to perform a cross domain request to WCF service which is hosted in Provider hosted Add-in. So ideally I am trying to get information from host web & perform some updates. But to start off , there is only one operation contract returning a string.
Please find the sample JavaScript:
try {
context = new SP.ClientContext(appWebUrl);
var executor = new SP.RequestExecutor(appWebUrl);
var localHostUrl = "http://amigosito365.azurewebsites.net/MyHybridService.svc/GetResponse";
//var localHostUrl = appWebUrl + "/_api/SP.AppContextSite(@target)/web/title?@target='" +
// hostWebUrl + "'";
executor.executeAsync(
{
url: encodeURIComponent(localHostUrl),
//url: localHostUrl,
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
success: onQuerySucceeded,
error: onQueryFailed,
DataType: "jsonp"
}
);
}
Using the above code, If I try to get the web title using the URL: //var localHostUrl = appWebUrl + "/_api/SP.AppContextSite(@target)/web/title?@target='" +
// hostWebUrl + "'";
I get the response json as expected however when I try to communicate with the RESTful service the response is not as excepted. I do not get any specific error and I am able to get in to the success call back function. But the body of data object has a big chunk of html and does not indicate any error.
On the other hand when I access the RESTful service in a web browser, I am seeing the response as expected.
Any help in solving the above issue would be really appreciated.
