我尝试在java中使用API提取数据。这样做时，API返回401：Unauthorized。我当前注册为管理员用户，并使用API密钥作为令牌。我还尝试使用声明令牌和使用setRequestProperty（“Authorization”，“token”，+ access-token）。您知道我可能做错了什么吗？
我也试过使用cURL和UI来达到类似的效果。我得到了我期望的输出，但在java中，这是一个身份验证问题。

public static void main(String[] args) {
        // TODO Auto-generated method stub
        //build each line and have a response to it 
        BufferedReader reader;
        String access_token = "abcde123 "; 
        String line;
        StringBuffer responseContentReader = new StringBuffer();
try {
    //URL url =  new URL("https://testurl.com");

    connection = (HttpsURLConnection) url.openConnection();

    connection.setRequestProperty("Authorization", "Token" + access_token);

    //here we should be able to "request" our setup
    //Here will be the method I will use 
    connection.setRequestMethod("GET");

    //after 5 sec if the connection is not successful time it out
    connection.setConnectTimeout(7000);
    connection.setReadTimeout(7000);

    int status = connection.getResponseCode();
    //System.out.println(status); //here the connect was established  output was 200 (OK)

    //here we are dealing with the connection isnt succesful
    if (status >299) {
        reader = new BufferedReader(new InputStreamReader(connection.getErrorStream()));
        while ((line = reader.readLine()) != null) {
            responseContentReader.append(" ");
            responseContentReader.append(line);
            responseContentReader.append("\n");
        }
        reader.close();
    //returns what is successful    
    }else {
        reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        while ((line = reader.readLine()) != null) {
            responseContentReader.append(" ");
            responseContentReader.append(line);
            responseContentReader.append("\n");
        }
        reader.close();
    }
    System.out.println(responseContentReader.toString());
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}catch (IOException e) {
    // TODO: handle exception
    e.printStackTrace();
}finally {
    connection.disconnect();
}
    }

}

字符串
我从控制台得到的输出是

{"success":"false","error":"unauthorized","message":"401 Unauthorized. No API key provided."}
