获取支付宝授权用户信息

登录 支付宝开放平台，创建应用

进入应用

在应用信息里设置两处，授权回调只需要到域名即可。

接口加签方式如下图

使用“支付宝密钥生成器”生成，如下图

将公钥复制到 接口加签方式 的公钥字符。

 

程序：

string auth_code = context.request.querystring["auth_code"];
string statestr = string.empty;
if (string.isnullorempty(auth_code)) //如果为空表示要获取
{
string parkid = context.request.querystring["sjh"];
string deviceid = context.request.querystring["deviceid"];
string paymodel = context.request.querystring["paymodel"];//支付方式：场内（payinpark）、出口（payoutpark）

statestr = string.format("sjh={0}&deviceid={1}&paymodel={2}", parkid, deviceid, paymodel);

//获取auth_code
string redirect_uri = "http://www.zftong.cn/cn.ubingo/alipayauth/getalipayauth.ashx";
redirect_uri = httputility.urlencode(redirect_uri);
string accessurl = "https://openauth.alipay.com/oauth2/publicappauthorize.htm?app_id={0}&scope=auth_base&redirect_uri={1}&state={2}";
string accurl = string.format(accessurl, alipayconfig.app_id, redirect_uri, desencrypt.encrypt(statestr));
context.response.redirect(accurl, true);
context.response.end();
return;
}

iaopclient client = new defaultaopclient("https://openapi.alipay.com/gateway.do", alipayconfig.app_id, alipayconfig.pri_key, "json", "1.0", "rsa2", alipayconfig.pub_key, "gbk", false);

//获取user_id和access_token
alipaysystemoauthtokenrequest request = new alipaysystemoauthtokenrequest();
request.granttype = "authorization_code";
request.code = auth_code;
alipaysystemoauthtokenresponse responseaccess_token = client.execute(request);
//获取用户信息 注：在获取auth_code时，如果是auth_base无法获取用户信息，需要auth_user
//alipayuserinfosharerequest requestuserinfo = new alipayuserinfosharerequest();
//alipayuserinfoshareresponse responseuserinfo = client.execute(requestuserinfo, responseaccess_token.accesstoken);
//string username = responseuserinfo.nickname;
