使用HttpUrlConnection将访问令牌发送回google api（401错误）

Question

我想访问Google Analytics管理API来创建视图，并测试了OAuth Playway使用scope as Analytics获取访问令牌。编辑令牌被测试为有效。然而，我在运行代码时不断遇到401错误

我的代码如下，编码语言是java

//where urlStr is https://www.googleapis.com/analytics/v3/management/accounts/accountId/webproperties/webPropertyId/profiles with relevant account id, web propertyId and inclusive of request body

String authEncoded = Base64.encodeBytes(accessToken.getBytes());

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("Authorization", "Basic " + authEncoded);
OutputStream output = connection.getOutputStream();


output.write(query.getBytes("UTF-8"));


InputStream response = connection.getInputStream();

以上代码在IOException的try catch中被包围。然而，来自输入流的响应总是给我一个错误

“java.io.IOException:服务器返回了URL的HTTP响应代码：401：”

我有没有遗漏什么，或者有没有其他方法来设置要发送到google api的访问令牌？

使用oauth。io/android，您可以使用它提供的信息直接构建您的请求：

data.http(urlStr, new OAuthRequest() {
    private URL url;
    private HttpURLConnection con;

    @Override
    public void onSetURL(String _url) {
        try {
            url = new URL(_url);
            con = (HttpURLConnection) url.openConnection();
        } catch (Exception e) { e.printStackTrace(); }
    }

    @Override
    public void onSetHeader(String header, String value) {
        con.addRequestProperty(header, value);
    }

    @Override
    public void onReady() {
        InputStream response = con.getInputStream();
        // ...
    }
});
