第三方平臺微信接口請求代碼

請求微信服務器獲取用戶數據工具類

使用http請求，使用fastjson將jsonString轉成object

public class WeiXinUtil {

	/**

		authUrl= authUrl.replace("APPID", Param.APPID);
		authUrl = authUrl.replace("SECRET", Param.SECRET);
		authUrl = authUrl.replace("CODE", code);

	/**

用到的類

<pre name="code" class="java">public class OAuthInfo {

	private String access_token;
	private String expires_in;
	private String refresh_token;
	private String openid;
	private String scope;
	private String unionid;
	
}

public class Token {
	private String access_token;
	private long expires_in;
	private long endTime;
	

	
}

public class User {

	private	int id;
	private	String subscribe;
	private	String nickname;
	private	String sex;
	private	String language;
	private	String city;
	private	String province;
	private String country;
	private	String headimgurl;
	private	String openid;
	private	String subscribe_time;
	private int number;
	private Gift gift;
	
	
}

public class Param {
<span style="white-space:pre">	</span>public static String APPID = "88888888";
<span style="white-space:pre">	</span>public static String SECRET = "88888888";
<span style="white-space:pre">	</span>public static String TICKET;
<span style="white-space:pre">	</span>public static Token TOKEN;
}

set/get方法都沒放上來，http請求和fastjson網上能夠找到
