DreamFactory's REST API POST request for rest/user/session consistently encounters errors in Internet Explorer 9

In Firefox, Chrome, and Safari, the initial POST rest/user/session request works perfectly fine. However, in Internet Explorer 9, it consistently returns an error.

When the dataType is specified as "json," IE9 encounters a 'no transport' error with a status of 0. On the other hand, when the dataType is set to "jsonp," IE9 receives an error object with a successful XHR status of 200 but with a parseError.

...


$.ajax({
    url: BASE_PATH + url,
    beforeSend: function (request) {
        request.setRequestHeader("X-DREAMFACTORY-APPLICATION-NAME", APP_NAME);
        request.setRequestHeader("X-DREAMFACTORY-SESSION-TOKEN", sessionStorage.SESSION_TOKEN);
        request.setRequestHeader("Content-Type","application/json");
        request.setRequestHeader("Accept","application/json");
    },
    method: method,
    contentType: "application/json; charset=utf-8",
    dataType: "jsonp",
    processData : processData,
    data: newdata,
    cache: false,
    success: function(response){
        console.log(arguments);
        $.jStorage.set("unique_session_id",response.session_id);
        sessionStorage.SESSION_TOKEN = response.session_id;
        runApp();
    },
    error: function(response){
        console.log(arguments);         
    }
});

Answer №1

For optimal performance, DreamFactory works best with IE10 or higher. The functionality of REST, CSS, etc. may not be fully supported in IE9.

If you are experiencing issues, I suggest attempting to access the REST URI directly in IE9 to verify if the response is being processed correctly. If it is successful, the problem might lie within your ajax script or implementation rather than DSP/IE9 compatibility.

Additionally, some quick research suggests enabling this option:

$.support.cors = true;
