Let's say I have url and don't know what it will return. I perform ajax call to that url with javascript
and get the content. So I test it's content-type and decide how to show response in my webpage.
In case it is json or html or any other text, I append the formatted content as I need.
Now when the content type is image, I get the image's data in response, which is not base64 encoded. I need to show the image in a regular <img>
tag of course. And here is where I get stuck.
Is there a way to show image from it's content data?
EDIT
Just to make it clear, hear is what I get in response:
"�PNG

First we give the button event listener, then inside it we fetch the data, after that you could alternatively console. log it first to see all the data you receive from the API, and then we assigned the image variable a source that referencing to the data that we just received. Don't forget to add .
Create “show()” function in JavaScript which can get the image and add the image source link to the src attribute.
This can be achieved using the pm. visualizer option and then setting the template to use basic img src HTML in the "Test" tab. If you then click on the "Visualize" tab you'll see the image...
var rawResponse = "�PNG...."; // truncated for example
// convert to Base64
var b64Response = btoa(rawResponse);
// create an image
var outputImg = document.createElement('img');
outputImg.src = 'data:image/png;base64,'+b64Response;
// append it to your page
document.body.appendChild(outputImg);
The accepted answer didn't worked for me. So here's my solution:
fetch
to download image, so I need to read response as blob
:let data; fetch(url).then(response => { response.blob().then(blobResponse => { data = blobResponse; }) });
const urlCreator = window.URL || window.webkitURL; document.getElementById('myImage').src = urlCreator.createObjectURL(data);
