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

maybe try to use all the header parameter postman use for the call and see what you have in encoding format response without JVM encoding force.

Hi, I think you can use tfileFetch component instead of tRestClient component. It will write directly the response into a file.

I just tried and it's ok with the tFileFetch component.

Thanks for all your messages and your help. Thank you very much.

Hello, I have the same problem as yours'. The authentication of API is Bearer token, not use+password, I couldn't use tFileFetch to get the picture. Do you have an idea?

Thanks a lot.

Hi , have you tried to add a header parameter :

key : "Authorization" value : "Bearer " + your token

?

Yeah then when I execute, I got this error "Exception in component tFileFetch_1 (...)

java.lang.Exception: Method failed: HTTP/1.1 405 "
