public void sample(AipNlp client)

{

   String word1 = "北京"; String word2 = "上海"; // 传入可选参数调用接口

   HashMap options = new HashMap();

   options.put("mode", 0); // 词义相似度

   JSONObject res = client.wordSimEmbedding(word1, word2, options);

   System.out.println(res.toString(2));

}

    运行后报错如下

   {
    "error_code": 282004,
    "error_msg": "invalid parameter(s)",
    "log_id": 613307206256948550
