tRestClient call of api to get a picture

[Swiip]

I use the tRestClient component to execute a GET on an API to get a picture in the answer.

I tried with Postman and i got a binary file with the extension ".bin".

If i rename this file with the extension ".jpg" i can see the picture.

But in Talend with tRestClient i can't generate the correct picture.

I tried to do this :

tRestClient => tmap => tFileOutputRaw

In the tmap i choose only the string (and not statusCode and body). In the tFileOutputRaw i generated a file. But it's not a picture. The size of this file is 24 ko. And with my test on Postman the size of the file is 25 ko. If i rename the file generated with the extension ".jpg" it isn't a picture.

Thank you very much for your help.

Have a good day

so :

"application/octet-stream; charset=WINDOWS-1252"

and -Dfile.encoding=windows-1252 in JVM ?

[Swiip]

I tried "application/octet-stream; charset=WINDOWS-1252" => file of 44 ko not correct

I tried -Dfile.encoding=windows-1252 in JVM => file of 24 ko not correct

[Swiip]

If i tried "application/octet-stream; charset=WINDOWS-1252" i have this log below so we can see that we haven't the same encoding in the response:

We can see this :

Response-Code: 200

Encoding: ISO-8859-1

Content-Type: application/octet-stream

[Swiip]

But in Postman i can see Content-Encoding=gzip

[Swiip]

and Content-Type = application/octet-stream

[gjeremy1617088143]

you can use Content-Type: application/octet-stream

and Content-Transfer-Encoding : base64.

then check the result in the string of the response and compare it to your document content in that you have to encode in base64.

If it's ok you have get the good encoded content of the document in base64.

so after you just have to decodebase64 and write it on a file as i mentionned before.

[Swiip]

I tried in http header in tRestClient Content-Type: application/octet-stream

and Content-Transfer-Encoding : base64

I generated again a file of 44ko.

Below the log. We can see again :

"Response-Code: 200

Encoding: ISO-8859-1

Content-Type: application/octet-stream"

It's really hard to debug tRestclient remotely, but you have an encoding issue for sure

[Swiip]

Yes but it's strange because when i change the http header of tRestclient with Content-Type parameter i have always in the log for the response :

Encoding: ISO-8859-1

Content-Type: application/octet-stream

as if I don't change anything
