Bind binary data from the ajax call response to sap.m.Image control.

Hello All,

I am trying to bind the response of the ajax call (which is a binary data) with sap.m.Image control.

But I couldnot see image in the control.


FYI.

I had to bind response from the ajax call because the service call because the service URL requires an access Token to be passed to it, then only I can see the image in the response.

Thanks,

Aakanksha

    Ok so i tried the same and got the issue as you said in reply to my previous answer. Below solution works quite fine. Please change it as per your requirement.

    $.ajax({
    	url: "imageUrl",
    	beforeSend: function (xhr) {
    		xhr.overrideMimeType('text/plain; charset=x-user-defined');
    	},
    	success: function (result, textStatus, jqXHR) {
    		if (result.length < 1) {
    			console.log("The thumbnail doesn't exist");
    			return;
    		}
    		var binary = "";
    		var responseText = jqXHR.responseText;
    		var responseTextLen = responseText.length;
    
    
    		for (var i = 0; i < responseTextLen; i++) {
    			binary += String.fromCharCode(responseText.charCodeAt(i) & 255);
    		}
    
    
    		that.getView().byId("imageId").setSrc("data:image/png;base64," + btoa(binary));
    	}
    });

    Hi Aakanksha Gupta

    You can use

    that.getView().byId("imageId").setSrc('data:image/png;base64,' + btoa(binary_data));

    Here binary_data is the response from your Ajax call and "that" is a variable declared outside the ajax call:

    let that=this;
