android - 发布 XML 请求和 XML 响应 Volley 库

Question

我已经集成了与 JSON 配合良好的 volley 库。现在正在尝试访问 WCF SOAP 我不知道如何将 XML 字符串作为请求传递以及如何获取 XML 字符串作为响应。

Answer 1

    // Tag used to cancel the request
    String  tag_string_req = "string_req";

    //String url = "URL......";



    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("Loading...");
    pDialog.show();

    StringRequest strReq = new StringRequest(Request.Method.POST,
            url, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            Log.d(TAG, response.toString());
            pDialog.hide();

        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(TAG, "Error: " + error.getMessage());
            pDialog.hide();
        }
    }){

        @Override
        public String getBodyContentType() {
            return "application/xml; charset=" +
                    getParamsEncoding();
        }

        @Override
        public byte[] getBody() throws AuthFailureError {
            String postData = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
                    "<sampletag>\n" +
                    "\t<sampletag>data</sampletag>\n" +
                    "</sampletag>"; // TODO get your final output
            try {
                return postData == null ? null :
                        postData.getBytes(getParamsEncoding());
            } catch (UnsupportedEncodingException uee) {
                // TODO consider if some other action should be taken
                return null;
            }
        }
        };

//添加请求到请求队列 AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
