*401 Unauthorized* When following tutorial Java implementation of Video.insert by developers.google.

Time:06-21

I am trying to upload an mp4 file to my youtube channel using the YouTube Data API, however, I keep getting a 401 Unauthorized back.

Using the google console cloud I created an (unrestricted) API key. Afterwards, I enabled YouTube Data API v3 I then copied the java code snippet from the use cases documentation for making a Video.Insert call to their services.

The things I changed from the snippet (required):

I used the aforementioned API key to replace "YOUR_API_KEY" And also replaced new File("YOUR_FILE") for obvious reasons. The file is a 17MB mp4 file.

Because the package provided with the snippet no longer comes with com.google.api.client.json.jackson2.JacksonFactory; Following this solution I included the dependency:

<dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client-jackson</artifactId>
    <version>1.29.2</version>
</dependency>

And I replaced JacksonFactory.getDefaultInstance() with new JacksonFactory()

Finally, as youtubeService.videos().insert(args) doesn't support a string as its first argument I replaced the string with a List.of() of the CSV string. I've also tried a List with each of the comma-seperated strings as items in the list but that doesn't seem to change the outcome either.

This results in the following request: https://youtube.googleapis.com/upload/youtube/v3/videos?key=MyKeyAware&part=snippet&part=status&uploadType=resumable

For good measure, here are the relevant dependencies I'm using (excluding the aforementioned dependency):

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.35.1</version>
</dependency>
<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-youtube</artifactId>
    <version>v3-rev20220612-1.32.1</version>
</dependency>

I would really appreciate some help as I've been struggling with this issue for a while now!

        Video response = request.setKey(DEVELOPER_KEY).execute();
        System.out.println(response);
    }

}

CodePudding user response:

It's unclear from your question but the error indicates that you're not including User authentication (OAuth) and this is required by the YouTube API:

See the Quickstart specifically creating OAuth client ID in step 2b.

The API key is used to authenticate your app.

The OAuth2 client ID is used to authenticate human users.
