please help: b64 problem google chart api
Ran the following via an anonymous block. Said:Unrecognized base64 character: � (actually a diamond shaped thing)
The returned value that is anticipated as being a png file is not in a format that can be converted into a b64 file accurately. Does anyone know any methods that might be able to produce a correct b64 string/blob?
If anyone knew how to fix this or had sample code for getting images from google chart api, i would appreciate it.
thank you
HttpRequest req = new HttpRequest();
req.setEndpoint('https://chart.googleapis.com/chart?chs=250x100&chd=t:60,40&cht=p3&chl=Hello|World');
req.setMethod('GET');
Http http = new Http();
HTTPResponse res = http.send(req);
blob body;
//body = blob.valueof(res.getBody());//produces corrupted body
body = EncodingUtil.base64Decode(res.getBody()); //crashes
it became apparent that the data returned was encrypted and would ordinarily be decrypted by the browser for display. Hence the difficulties with the blob conversion. I hadn't noticed the part of the header that indicated this. I haven't located the methods to decrypt this thing yet, rather had adopted an alternative approach.
I had same problem, I was under the impression the responce from google chart was not base64 but the binary representation of the image.
Did you manage to solve this? I am trying to get a jpg from a URL and save it as an attachment, bu tam getting a similar issue.
