微信公众号授权给开放平台
公众号授权给第三方平台的技术实现流程比较简单
这个步骤遗漏了开头获取第三方平台自己的accessToken
先说下流程
如何注册开放平台的第三方信息看截图
其他不说了，此文只说代码部分。
先获取第三方10分一次的ticket。
1 using (var streamReader = new StreamReader(Request.InputStream))
2 {
3 string stringInput = streamReader.ReadToEnd();
4 string sMsg = ""; //解析之后的明文
5 int ret = 0;
6 ret = wxcpt.DecryptMsg(signature, timestamp, nonce, stringInput, ref sMsg);
7 if (ret != 0)
8 return Content(string.Format("解析错误{0}", ret));
9 var xDoc = XDocument.Parse(sMsg);
10 var q = (from c in xDoc.Elements() select c).ToList();
11 var infoType = q.Elements("InfoType").First().Value;
12 switch (infoType)
13 {
14 case "component_verify_ticket":
15 var ComponentVerifyTicket = q.Elements("ComponentVerifyTicket").First().Value;
16 var wxOpen = (WebProject_GlobalConfig)WCFHelper.Invoke("WebProject_GlobalConfig", WcfFunName.SelectSingle.ToString(),
17 new object[] { "4add738c-369d-4570-ad18-77542e18a47a"});//这条请无视，只是wcf取数据。
18 wxOpen.KeyValue = ComponentVerifyTicket;
19 wxOpen.ModifyTime = DateTime.Now;
20 wxOpen = (WebProject_GlobalConfig)WCFHelper.Invoke("WebProject_GlobalConfig", WcfFunName.Save.ToString(),
21 new object[] { wxOpen });
22 return Content("success");
23 case "unauthorized":
24 return Content(string.Format("{0} 已取消授权", q.Elements("AuthorizerAppid").First().Value));
25 default:
26 break;
27 }
28 }
29 return Content("参数错误！");
获取到的信息解密，并保存component_verify_ticket。
然后就开始做第三方的token事情！
拿accesstoken
var accessTokenTime = wxOpen.ModifyTime;
if (accessTokenTime < DateTime.Now.AddSeconds(-7200) | String.IsNullOrEmpty(wxOpen.KeyValue))
{
dynamic authorizerResult = ComponenToken();
wxOpen.ModifyTime = DateTime.Now;
wxOpen.KeyValue = authorizerResult.component_access_token;
WCFHelper.Invoke("WebProject_GlobalConfig", WcfFunName.Save.ToString(), new object[] { wxOpen });
}
/// <summary>
/// Ticket票据读取第三方token
/// </summary>
/// <returns></returns>
public static dynamic ComponenToken()
{
var url = "https://api.weixin.qq.com/cgi-bin/component/api_component_token";
var jsonDate = new
{
component_appid = GetConfig("ComponentAppid"),
component_appsecret = GetConfig("ComponentSercet"),
component_verify_ticket = GetConfig("ComponentVerifyTicket")
};
return CommonJsonSend.Send<dynamic>(null, url, jsonDate);
}
然后就可以做授权跳转
/// <summary>
/// 跳转授权
/// </summary>
/// <returns></returns>
public ActionResult WxRedirect()
{
var url = "https://mp.weixin.qq.com/cgi-bin/componentloginpage?component_appid={0}&pre_auth_code={1}&redirect_uri={2}";//跳转网页
var proResult = WeChatTokenHelper.GetProCode();//预授权码
url = String.Format(url, WeChatTokenHelper.GetConfig("ComponentAppid"), proResult.pre_auth_code, "http://XXXXX/DptWxOpen/AuthInfo");
return Redirect(url);
}
不知道怎么拿预授权码？好吧，看代码！
/// <summary>
/// 第三方token读取预授权读取
/// </summary>
/// <param name="Ticket"></param>
/// <returns></returns>
public static dynamic GetProCode()
{
var url = "https://api.weixin.qq.com/cgi-bin/component/api_create_preauthcode?component_access_token={0}";
var jsonData = new
{
component_appid = GetConfig("ComponentAppid")
};
return CommonJsonSend.Send<dynamic>(GetOpenToken(), url, jsonData);
}
最后的悲哀授权成功回调~
/// <summary>
/// 微信回调url
/// </summary>
/// <param name="auth_code"></param>
/// <returns></returns>
public ActionResult AuthInfo(String auth_code)
{
var admin = Session["WebAdmin"] as WebProject_Admin; //登陆身份而已，别太在意
if (admin == null)
return Redirect("/DptPages/Login");
dynamic tokenResult = WeChatTokenHelper.GetWeChat(auth_code);//换授权码
dynamic authorizationInfo = tokenResult.authorization_info;
String appId = authorizationInfo.authorizer_appid;
var authorizerInfo = (WebProject_AuthorizerWeChat)WCFHelper.Invoke("WebProject_AuthorizerWeChat", WcfFunName.SelectSingle.ToString(),
new object[] { "x.WebId == " + admin.WebId, true });
if (authorizerInfo == null)
{
authorizerInfo = new WebProject_AuthorizerWeChat
{
WebId = admin.WebId
};
authorizerInfo = (WebProject_AuthorizerWeChat)WCFHelper.Invoke("WebProject_AuthorizerWeChat", WcfFunName.Save.ToString(),
new object[] { authorizerInfo });
}
if (authorizerInfo == null)
return Content("对象报错！");
authorizerInfo.AppId = appId;
authorizerInfo.AccessToken = authorizationInfo.authorizer_access_token;
authorizerInfo.AccessTokenTime = DateTime.Now;
authorizerInfo.RefreshToken = authorizationInfo.authorizer_refresh_token;
var Func = JSON.Deserialize<func_info>(funcinfo(authorizationInfo.func_info));
var Json = "";
foreach (var i in Func.Info)
{
i.funcscope_category.FuncType = i.funcscope_category.id > 0 ? (FuncType)i.funcscope_category.id : FuncType.Error;
Json += JSON.ToJson(i);
}
authorizerInfo.FuncInfo = Json;
authorizerInfo = (WebProject_AuthorizerWeChat)WCFHelper.Invoke("WebProject_AuthorizerWeChat", WcfFunName.Save.ToString(),
new object[] { authorizerInfo });
return Redirect("WeChatInfo?state=true");
}
好人做到底，授权码方法：
/// <summary>
/// 授权码code换身份
/// </summary>
/// <param name="authCode"></param>
/// <returns></returns>
public static dynamic GetWeChat(String authCode)
{
var url = "https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token={0}";
var jsonData = new
{
component_appid = GetConfig("ComponentAppid"),
authorization_code = authCode
};
return CommonJsonSend.Send<dynamic>(GetOpenToken(), url, jsonData);
}
几个关于授权信息的类工具：
#region AuthorInfo Helper
public string funcinfo(dynamic info)
{
string newinfo = "{\"Info\":" + info + "}";
return newinfo;
}
public class func_info
{
public List<InfoList> Info { get; set; }
}
public class InfoList
{
public Info funcscope_category { get; set; }
}
public class Info
{
public Int32 id { get; set; }
public FuncType FuncType { get; set; }
}
#endregion
