Volley框架设置sessionid

（偷懒，写简略点）

自定义一个Request类

public class MyRequest extends Request<JSONObject>

 

存储上一次连接的sessionid

@Override

protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {

try

{

Map<String, String> responseHeaders = response.headers;

Log.e("MyRequest", "response:" + responseHeaders.toString());

String rawCookies = responseHeaders.get("Set-Cookie");

SharedPreferencesUtil.putString("sessionid",rawCookies.substring(0, rawCookies.indexOf(";")));

Log.e("MyRequest", "parseNetworkResponse() sessionId:" + sessionId);

 

}

 

下一次连接报文头加上sessionid

@Override

public Map<String, String> getHeaders() throws AuthFailureError {

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

sessionId=SharedPreferencesUtil.getString("sessionid");

// Log.e("MyRequest", "getHeaders() sessionId:" + sessionId);

if (!TextUtils.isEmpty(sessionId)) {

headers.put("cookie", "" + sessionId);

}

return headers;

}

 

如：获取验证码注册（获取验证码是返还一个sessionid，注册时加上该sessionid）
