不能通过谷歌API授权

Question

我正在开发一个应用程序内购买，所以我想知道订阅是否过期。我已经获得了RefreshToken和AccessToken，但是当我试图根据此获取订阅信息时，我总是得到相同的错误：{“错误”：{“错误”:[
{“域”：“全局”，
“原因”：“autherror”，
“消息”：“无效凭据”，
“位置类型”：“头”，
“位置”：“授权”}]，
“代码”:401，
“消息”：“无效凭据”}}

 String urlt = " https://www.googleapis.com/androidpublisher/v3/applications/" + PACKAGE_NAME + "/purchases/subscriptions/" + SUBSCR_ID + "/tokens/" + accessToken;
        DefaultHttpClient client = new DefaultHttpClient();
        HttpGet post = new HttpGet(urlt);
        post.setHeader("Scope" , "https://www.googleapis.com/auth/androidpublisher");
        post.setHeader("Authorization" , "Bearer" + accessToken);
        try {
            org.apache.http.HttpResponse response = client.execute(post);
            BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            StringBuffer buffer = new StringBuffer();
            for (String line = reader.readLine(); line != null; line = reader.readLine()) {
                buffer.append(line);
            }

            JSONObject json = new JSONObject(buffer.toString());
           int x = 0;
        }
        catch (Exception e) {
            e.printStackTrace();
        }

参考RFC6750，在“承载”和令牌之间需要有一个空格。

将代码更改为：

post.setHeader("Authorization" , "Bearer " + accessToken);
