If you have a service which returns a payload like the following (including a base64 encoded jpeg) you can display it directly in postman.
1 2 3 4 5 | { "photo": "/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAMCAgMCAgMDAwMEAwMEBQgFBQQEBQoHBwYIDAoMDAsK\r\nCwsND..............", "photoId": "192", "mimeType": "image/jpeg"} |
This can be done with a few lines of code. In Postman navigate to the “Tests” tab:
and insert the following lines:
01 02 03 04 05 06 07 08 09 10 | //output to postman consoleconsole.log("PhotoId: " + pm.response.json()["photoId"]);console.log("Base64: " + pm.response.json()["photo"]);//output in visualize tablet template = `<img src='{{img}}'/>`;pm.visualizer.set(template, { img: `data:image/jpeg;base64,${pm.response.json()["photo"]}`}); |
In the “Visualize” tab you should now find your image
I tried the above script and I got the following message back. What have I missed please
There was an error in evaluating the test script: JSONError: Unexpected token ‘<' at 1:1 ^
Are you sure the response is a valid json?
Try to remove everything and start with console.log(pm.response.json()); only. If this already fails, I guess your response is not a valid json.
This has helped me a lot. Thank you
