1.客户端以普通的post方式进行提交，服务端返回字符串
RequestQueue requestQueue =Volley.newRequestQueue(this);
StringRequest stringRequest=new StringRequest(Request.Method.POST,httpurl,
new Response.Listener<String>(){
@Override
public void onResponse(String response){
System.out.println("response="+response);
//已经获取了数据
}
},new Response.ErrorListener(){
@Override
public void onErrorResponse(VolletError error){
System.out.println("sorry,Error");
}
}){
@Override
protected Map<String,String> getParams(){
Map<String,String> map=new HashMap<String,String>();
map.put("name","value");
return params;
}};
requestQueue.add(stringRequest);
2.客户端以json串的post请求方式进行提交，服务端返回json串
RequestQueue requestQueue =Volley.newRequestQueue(this);
Map<String,String> map=new HashMao<String,String>();
map.put("name1","value1");
map.put("name2","value2");
JSONObject jsonObject=new JSONObject(params);
JsonRequest<JSONObject> jsonRequest=new JsonObjectRequest(Method.POST,httpurl,jsonObject,
new Response.Listener<JSONObject>(){
@Override
public void onResponse(JSONObject response){
System.out.println("response="+response.toString());
}
},new Response.ErrorListener(){
@Override
public void onErrorResponse(VooleyError error){
System.out.println("sorry,Error");
}
}){
//注意此处override的getParams()方法,在此处设置post需要提交的参数根本不起作用
//必须象上面那样,构成JSONObject当做实参传入JsonObjectRequest对象里
//所以这个方法在此处是不需要的
// @Override
// protected Map<String, String> getParams() {
// Map<String, String> map = new HashMap<String, String>();
// map.put("name1", "value1");
// map.put("name2", "value2");
// return params;
// }
@Override
public Map<String,String> getHeaders(){
HashMap<String,String> headers=new HashMap<String,String>();
headers.put("Accept","application/json");
headers.put("Content-type","application/json;chaset=UTF-8");
return headers;
}
};
requestQueue.add(jsonRequest);
3.客户端以普通的post方式进行提交，服务端返回json串
首先在Activity类里，集成Request实现一个NormalPostRequest类
priavte class NormalPostRequest(String url,Listener<JSONObject> listener,
ErorListener errorListener,Map<String,String> map){
super(Request.Mthod.POST,url,errorListener);
mListener=listener;
mMap=map;
}
//mMap是已经按照前面的方式，设置了参数的实例
@Override
protected Map<String,String> getParams() throws AuthFailureError{
return mMap;
}
@Override
protected Response<JSONObject> parseNetworkResponse(NewworkResponse response){
try{
String jsonString=new String(response.data,HttpHeaderParse.parseCharset(response.headers));
return Response.success(ne JSONObject(josnString),HttpHeaderParser.parseCacheHeaders(response));
}catch(UnsupportedEncodingException e){
return Response.error(new ParseError(e));
}catch(JSONException je){
return Response.error(new ParseError(je));
}
}@Override
protected void deliverResponse(JSONObject response){
mListener.onResponse(response);
}
}
接下来的调用方式和前面差不多，生成一个Request实例，加入列队中即可
RequestQueue requestQueue=Volley.newRequestQueue(getApplicationContexe());
Request<JSONObject> request=new NormalPostRequest(httpurl,
new Response.Listener<JSONObject>(){
@Override
public void onResponse(JSONObject response){
System.out.println("response="+response.toString());
}
},new Response.ErrorListener(){
@Override
public void onResponse(VolleyError error){
Log.e("TAG",error.getMessage(),error);
}
},params);
requestQueue.add(request);
