Android Question SetContentType

[marcel]

Hi,

I am trying to use the following code to set the content type:

    Dim job As HttpJob
    job.Initialize("datadownload",Me)
    job.Download(URL)
    job.GetRequest.SetContentType("application/json")

but when I do this I get the following error:

java.lang.RuntimeException: Only Post / Put requests support this method.

What is wrong with this code? I am using httputils2 (v2.01)

Get requests should not have a content-type because they do not have request entity...in other words, you don't need it. In the job done sub you have to know what the stream is (bitmap, text so on) and decide what to do...

Ok. I do I change this to a post. I need to set the content type?

 

[DonManfred]

Usually not.
It depends in the requirements of the server

 

[marcel]

The server requires to set the content type and I can also post information. But I am not sure how to do this...

 

[DonManfred]

What data do you need to transport/post?

Here an example of my DropboxClass

    Dim job As HttpJob
    job.Initialize("getaccount",Me)
    job.PostString(mApiV2url&"users/get_account",$"{"account_id":"${accountID}"}"$)
    job.GetRequest.SetHeader("Authorization", "Bearer "&mAccessToken)
    job.GetRequest.SetHeader("Content-Type", "application/json")
    job.GetRequest.SetContentType("application/json")
    job.GetRequest.SetContentEncoding("text/plain")

$"{"account_id":"${accountID}"}"$ is the content who will be POSTed.

For ex:

{"account_id":"1234"}
