android使用volley框架访问https

volley是Android开发团队在2013年Google I/O大会上推出了一个新的网络通信框架。因为公司服务端与android通信采用https协议，android用的访问网络框架就是volley。现在将项目中使用volley访问https的方法记录一下。

1.首先下载volley框架，下载地址http://download.csdn.net/detail/jifashihan/9316875。将volley.jar复制到Android Studio中libs文件夹中，右键点击jar，选择"Add As Library"

2.将需要用到的类下载下来，下载地址http://download.csdn.net/detail/jifashihan/9317813。将.java文件复制到工程中，将.jar文件复制到libs文件夹下，并引用

3.创建一个单例类。

public class VolleySingleton {

private static VolleySingleton volleySingleton;

private RequestQueue mRequestQueue;

private ImageLoader mImageLoader;

private Context mContext;

public VolleySingleton(Context context) {

this.mContext = context;

mRequestQueue = getRequestQueue();

mImageLoader = new ImageLoader(mRequestQueue,

new ImageLoader.ImageCache(){

private final LruCache<String,Bitmap> cache = new LruCache<String ,Bitmap>(20);

@Override

public Bitmap getBitmap(String url){

return cache.get(url);

}

@Override

public void putBitmap(String url,Bitmap bitmap){

cache.put(url,bitmap);

}

});

}

public static synchronized VolleySingleton getVolleySingleton(Context context){

if(volleySingleton == null){

volleySingleton = new VolleySingleton(context);

}

return volleySingleton;

}

public RequestQueue getRequestQueue(){

if(mRequestQueue == null){

InputStream keyStore =mContext.getResources().openRawResource(R.raw.server);

mRequestQueue = Volley

.newRequestQueue(mContext,

new ExtHttpClientStack(new SslHttpClient(keyStore, "123456", 443)));

//mRequestQueue = Volley.newRequestQueue(mContext.getApplicationContext());

}

return mRequestQueue;

}

public <T> void addToRequestQueue(Request<T> req){

getRequestQueue().add(req);

}

public ImageLoader getImageLoader() {

return mImageLoader;

}

}

其中 InputStream keyStore =mContext.getResources().openRawResource(R.raw.server);是读取raw文件夹下的server.bks，也就是服务端生成的证书。new SslHttpClient(keyStore, "123456", 443)，123456是密码，443是端口。

4.创建volley访问网络的通用方法，因为服务器接口是post类型的，所以封装post方法

public class VolleyMethods {

private String result = "";//访问数据,返回结果

private Context mContext;

private RequestQueue mRequestQueue;

public VolleyMethods(Context context) {

mContext = context;

mRequestQueue = VolleySingleton.getVolleySingleton(mContext).getRequestQueue();

}

/**

* Post

*

* @param url 访问url

* @param requestTag 请求Tag，用于停止请求

* @param paramkeys Post参数的key

* @param paramValues Post参数的value

*/

public void StringRequestPostMethod(String url, String requestTag, final ArrayList<String> paramkeys, final ArrayList<String> paramValues

,Response.Listener<String> listener,Response.ErrorListener errorListener) {

result = "";

StringRequest stringRequest = new StringRequest(Request.Method.POST, url, listener, errorListener) {

@Override

protected Map<String, String> getParams() throws AuthFailureError {

Map<String, String> map = new HashMap<String, String>();

for (int i = 0; i < paramkeys.size(); i++) {

map.put(paramkeys.get(i), paramValues.get(i));

}

return map;

}

};

stringRequest.setTag(requestTag);

mRequestQueue.add(stringRequest);

}

}

5.调用volley访问网络

//得到获取验证码接口,返回参数名。StaticParameter.interfaceUrl接口地址，interfaceMethodName接口名称

public static ArrayList<String> SendCaptchaMethod(){

interfaceMethodName = StaticParameter.interfaceUrl+"sendCaptcha";

ArrayList<String> paramkeys = new ArrayList<String>();

paramkeys.add("phonenumber");

return paramkeys;

}

//调用获取验证码的接口

final VolleyMethods volleyMethods = new VolleyMethods(ForgetPasswordActivity.this);

ArrayList<String> paramkeys = new ArrayList<String>();

ArrayList<String> paramValues = new ArrayList<String>();

paramValues.add(userPhone);

paramkeys = UrlInterfaceMethods.SendCaptchaMethod();

volleyMethods.StringRequestPostMethod(UrlInterfaceMethods.interfaceMethodName,

"SendCaptcha", paramkeys, paramValues, new Response.Listener<String>() {

@Override

public void onResponse(String s) {

Log.e("", s);

}

}, new Response.ErrorListener() {

@Override

public void onErrorResponse(VolleyError volleyError) {

Log.e("volleyError", volleyError.toString());

}

});
