Access to Android Volkswagen reviews

Here is a popular review of the purchase of an interface, that is, all group purchase information, the implementation of the other interface is similar.

First, a public review of the development platform, which is logged in to Volkswagen reviews. Then get to your own application of Appkey and secret, this is a prerequisite for development. You can download the Demo->demo provided by the Volkswagen reviews.

Get all group purchase information:

Dzdpapitool.java Volkswagen reviews the API tool classes provided (Request API, Requestapi this method)

Then call the interface

map<string, string> parammap = new hashmap<string, string> ();p arammap.put ("City", city);p Arammap.put (" Limit ", 1);p arammap.put (" page ", offset +");p Arammap.put ("region", region);D Zdpapitool.requestapi (HTTP// Api.dianping.com/v1/deal/find_deals, Appkey, sign, parammap);
