Error 414 when trying to send base64 image through URL

OCR.space Free OCR API

Hello,
I am trying to send a base64 image through the url but it keeps giving me “Error 414 Request URL is too Long”.
I am using javascript in a mobile development platform called Kony.
I implemented sending image through URL in GET and it is working perfectly.

request.open(constants.HTTP_METHOD_POST, "https://api.ocr.space/parse/image?apikey=" + apiKey + "&base64Image=data:image/jpeg;base64," + this.view.camera.base64 + "&filetype=JPG", false);

request.setRequestHeader("Content-type","image/jpg");

I am using the image taken from the phone camera as base64. I made sure that the type is JPG.
Please provide help if you can. Thanks in advance.

Does the same request work in Postman?

I am sorry for the late reply.
The same request doesn’t work in Postman too. I tried different image sizes.
On medium sized images I get Error 414 Request URL is too long and on small images I get Error 400 header too long.

If it does not work in Postman, then my guess is that something is wrong with your base64 string. How big is the image? And how long the string? If you generate a base64 string from a small image, does it work then?

The image is about 20kb and in base64 is 32k characters.
The small image in base64 is 16k characters.

In medium image I get error 414 request url is too long.
In small image I get error 400 header too long.

…it seems something is wrong with your base64 string. You can test your string with one of the online base64 converter tools, for example https://codebeautify.org/base64-to-image-converter

And here is a base64 string that works:
