弹性搜索不是x内容异常

Question

我一直在尝试java使用以下代码将数据放入弹性搜索中:

String url = "http://localhost:9200/testindex2/test/2";
    HttpClient client = new DefaultHttpClient();

    HttpPut put = new HttpPut(url);
    JSONObject json = new JSONObject();

    json.put("email", "abc@abof.com");
    json.put("first_name", "abc");
    StringEntity se = new StringEntity("JSON: " + json.toString());
    se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"Text"));
    put.setEntity(se);

    HttpResponse response = client.execute(put);
    System.out.println("\nSending 'PUT' request to URL : " + url);
    System.out.println("Put parameters : " + put.getEntity());
    System.out.println("Response Code : " + response.getStatusLine().getStatusCode());

   BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }

    System.out.println(result.toString());

我收到以下错误:

向URL发送'PUT'请求:http:// localhost:9200/testindex2/test/2 放置参数:[Content-Type:text/plain; charset = ISO-8859-1,Content- Encoding:Text,Content-Length:52,Chunked:false]响应代码:400 {"error":{"root_cause":[{"type":"mapper_parsing_exception","reason ":"无法解析"}],"类型":"mapper_parsing_exception","reason":"无法解析","caused_by":{"type":"not_x_content_exception","reason":"压缩器检测只能在某些xcontent字节或压缩的xcontent字节"}}上调用,"status":400}

此外,当我从其他客户端尝试相同的代码时,它运行得很好,不知道为什么会出现这个问题.

已更换

 StringEntity se = new StringEntity("JSON: " + json.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"Text"));

有了这个：

StringEntity se = new StringEntity(json.toString(),ContentType.APPLICATION_JSON);

现在正在工作
