Hi there
New to Kendo
Hoping for some direction here. When i use the following code i keep getting a 401 error. The username and password are correct
var dataSource = new kendo.data.DataSource({
autoSync: true,
transport: {
read: {
url: "web service url",
beforeSend: function (xhr) {
//your code
xhr.setRequestHeader("Authorization", "Basic username:password"); //i set the username and password to valid settings
},
dataType: "jsonp" // "jsonp" is required for cross-domain requests; use "json" for same-domain requests
},
update: {
url: "web service url",
dataType: "jsonp" // "jsonp" is required for cross-domain requests; use "json" for same-domain requests
}
},
schema: {
model: { id: "Id" }
}
});
If i use eclipse and build an android app i can set the username and password properties of the DefaultHttpClient and i can connect successfully, so it appears the service works (I can also access it via a browser which prompts for credentials and i get the data)
any ideas ??

Hello,

The problem is caused by the JSONP dataType setting. jQuery doesn't use an XMLHttp request when performing JSONP requests. As a result you cannot set request headers. Try setting the dataType option to "json" if your service is in the same domain.

Thanks for the reply Atanas
I set the dataType option to json with no luck. The service is outside of our domain, and clients will be accessing it via the internet. Anything else you can think of ???

Hi,

Since setting the request header is supported only for json requests I cannot think of a workaround.

I managed to get this working by encoding the username:password combination
Now just make sense of the data

Can someone give an example of this? I am trying to authenticate to a service outside of our domain so I need to set the authentication header and use jsonp?
If this is not possible what is the recommended way to authenticate with a service outside my domain?

Hello Jonathan,

Setting any HTTP headers isn't possible with JSONP. The latter works by dynamically injecting <script> elements in the page which doesn't allow setting http headers. The only suggestion we can give is to use CORS if possible.

Can you post your code, please? I'm working on this too.
