Way to workaround invalid Content-Type header in a response?

[Alexander Devine]

I am attempting to access a server that I realized is sending an invalid Content-Type header. The value it is sending is just "text" instead of "text/plain", which is causing the request to fail with the following stack trace:

Caused by: java.lang.IllegalArgumentException: Type must be in the 'maintype/subtype; parameter=value' format

at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:92)

at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:49)

at com.google.api.client.http.HttpMediaType.fromString(HttpMediaType.java:167)

at com.google.api.client.http.HttpMediaType.<init>(HttpMediaType.java:111)

at com.google.api.client.http.HttpResponse.<init>(HttpResponse.java:157)

at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:984)

...

Does anyone have an idea if there is a way I could work around this in the client? Since the exception is thrown in the HttpResponse constructor I can't just fix it with an response interceptor.

Thanks,

Alex

Second this - I'm running into the same issue and can't override the HttpMediaType, which has been declared as final. Trying to handle requests that do not have a full set of headers. Is there some way of setting parsing to be more forgiving?

Thanks.

Did you ever solve this issue? I have the same error in my application, and I can't find a solution for it.

It seems like a bug on the Google side since the download url is given by the Google Drive API, right?

The ultimate solution is obviously to fix the server to return correctly formatted media types. In the current client implementation, there isn't a clean way to override HttpMediaType parsing. However, if you really need it, you can implement your own LowLevelHttpRequest/LowLevelHttpRespone/HttpTransport, where you parse media type more forgivingly. For example, you could return 'Content Type: text/plain' in your LowLevelHttpResponse.getContentType() when you see 'Content Type: text'.

Mikael, did you say that the Google Drive API is returning such a content type?
