直接上代码

@Override
public JSONObject getCameraList(int current, int size, String code, String name) throws IOException {

    DefaultHttpClient client = new DefaultHttpClient();

    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.setCharset(Charset.forName("utf-8"));
    ContentType contentType = ContentType.create("multipart/form-data", Charset.forName("UTF-8"));
    builder.addTextBody("pageNo", String.valueOf(current), contentType);
    builder.addTextBody("pageSize", String.valueOf(size), contentType);
    builder.addTextBody("regionIndexCode", code, contentType);
    builder.addTextBody("treeCode", "0", contentType);
    builder.addTextBody("name", name, contentType);

    HttpEntity multipart = builder.build();


    //访问地址
    String url = "http://192.168.3.21:8888/hk/getAllDeviceByLevel";

    HttpPost httpPost = new HttpPost(url);
    httpPost.setEntity(multipart);
    HttpResponse response2 = null;
    response2 = client.execute(httpPost);
    HttpEntity entity2 = null;
    entity2 = response2.getEntity();

    String s2 = EntityUtils.toString(entity2, "UTF-8");
    JSONObject js01 = (JSONObject) JSONObject.parse(s2);


    return js01;
}

这里注意如果直接将中文传入 会传得事乱码报错，一定要转为utf-8格式  传参才会事中文
