在来自 Android Volley 的 POST 请求中发送 JSON 对象接收 java restful webservices

Question

我想要一个小例子来发送来自 android volley 的 POST 请求中的 JSON 对象，它必须接收 Java Restful Webservices

Answer 1

您可以使用以下工作示例代码。希望这会有所帮助！

        ...   
        try {
            RequestQueue queue = Volley.newRequestQueue(this);
            jsonBody = new JSONObject();
            jsonBody.put("Title", "VolleyApp Android Demo");
            jsonBody.put("Author", "BNK");
            jsonBody.put("Date", "2015/08/26");
            requestBody = jsonBody.toString();

            StringRequest stringRequest = new StringRequest(1, url, new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    textView.setText(response);
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    textView.setText(error.toString());
                }
            }) {
                @Override
                public String getBodyContentType() {
                    return String.format("application/json; charset=utf-8");
                }

                @Override
                public byte[] getBody() throws AuthFailureError {
                    try {
                        return requestBody == null ? null : requestBody.getBytes("utf-8");
                    } catch (UnsupportedEncodingException uee) {
                        VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",
                                requestBody, "utf-8");
                        return null;
                    }
                }
            };
            queue.addToRequestQueue(stringRequest);
        } catch (JSONException e) {
            e.printStackTrace();
        }

另外，你能澄清一下it has to receive Java Restful Webservices 是什么意思吗？我的上述请求收到 String 值。
