volley 获取cookie总结

1.获取服务器返回的cookie值，重写request中的parseNetworkResponse方法就可以了
[java] view plaincopy
StringRequest request= new StringRequest(Method.POST, url, 
             this, this) { 
          
            @Override 
            protected Response<String> parseNetworkResponse( 
                    NetworkResponse response) { 
                // TODO Auto-generated method stub 
                try { 
                      
                    Map<String, String> responseHeaders = response.headers; 
                    String rawCookies = responseHeaders.get("Set-Cookie"); 
                    String dataString = new String(response.data, "UTF-8"); 
                    return Response.success(dataString,HttpHeaderParser.parseCacheHeaders(response)); 
                } catch (UnsupportedEncodingException e) { 
                    return Response.error(new ParseError(e)); 
                }  
            } 
 
        }; 
2.有时服务器会返回多个 Set-Cookie 值，而Volley默认只取第一个，如果有需求，就要自己修改Volley的代码啦，HurlStack（sdk_int>9会走这里)里面的performRequest，默认解析header方式如下，

多个值的话只需要拿到header.getValue().get(1)等等，具体需求可以自行修改。

[java] view plaincopy
Header h = new BasicHeader(header.getKey(), header.getValue().get(0)); 
response.addHeader(h); 

3.给服务器上传Cookie值，如下（因为该类实现了response和error接口，所以参数直接写的this）

[java] view plaincopy
StringRequest request= new StringRequest(Method.POST, url, 
         this, this) { 
        public Map<String, String> getHeaders() throws AuthFailureError { 
            HashMap localHashMap = new HashMap();    
            localHashMap.put("Cookie", "你的cookie值"); 
            return localHashMap; 
        } 
        //设置post参数 
        protected Map<String, String> getParams() { 
            if(params==null){ 
                return new HashMap<String, String>(); 
            } 
                return params; 
        } 
[java] view plaincopy
                      //设置编码格式 
    @Override 
    protected Response<String> parseNetworkResponse( 
            NetworkResponse response) { 
        // TODO Auto-generated method stub 
        try { 
            String dataString = new String(response.data, "UTF-8"); 
            return Response.success(dataString,HttpHeaderParser.parseCacheHeaders(response)); 
        } catch (UnsupportedEncodingException e) { 
            return Response.error(new ParseError(e)); 
        }  
    } 
 
};
