java中http调用接口 传参为form-data

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)
