这里所说的高级接口是指面向通过认证的服务号开通的高级功能。
高级功能大致可以分类为：
- 用户接口
- 分组接口
- 客服接口（有别于之前介绍的多客服）
- 群发接口
- 多媒体接口
- 二维码接口
- 模板消息接口（不是所有账号都可开通）
- OAuth2.0（相对比较复杂，后面会有专门介绍）
以上所有的接口都包含在Senparc.Weixin.MP.AdvancedAPIs命名空间下。
一些共同的操作
几乎所有的高级接口都需要用到AccessToken来通讯（注意，下面如果没有特殊说明的接口都需要这个AccessToken，但并非所有），因此多数会有一个AccessToken参数传入，有关AccessToken获取和操作的方式见Senparc.Weixin.MP SDK 微信公众平台开发教程（八）：通用接口说明。
用户接口
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/User
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
//接口详见：http://mp.weixin.qq.com/wiki/index.php?title=%E8%8E%B7%E5%8F%96%E7%94%A8%E6%88%B7%E5%9F%BA%E6%9C%AC%E4%BF%A1%E6%81%AF
/// <summary>
/// 用户接口
/// </summary>
public static class User
{
/// <summary>
/// 获取用户信息
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="openId">普通用户的标识，对当前公众号唯一</param>
/// <param name="lang">返回国家地区语言版本，zh_CN 简体，zh_TW 繁体，en 英语</param>
/// <returns></returns>
public static UserInfoJson Info(string accessToken, string openId, Language lang = Language.zh_CN)
{
string url = string.Format("https://api.weixin.qq.com/cgi-bin/user/info?access_token={0}&openid={1}&lang={2}",
accessToken, openId, lang.ToString());
return HttpUtility.Get.GetJson<UserInfoJson>(url);
//错误时微信会返回错误码等信息，JSON数据包示例如下（该示例为AppID无效错误）:
//{"errcode":40013,"errmsg":"invalid appid"}
}
/// <summary>
/// 获取关注着OpenId信息
/// </summary>
/// <param name="accessToken"></param>
/// <param name="nextOpenId"></param>
/// <returns></returns>
public static OpenIdResultJson Get(string accessToken, string nextOpenId)
{
string url = string.Format("https://api.weixin.qq.com/cgi-bin/user/get?access_token={0}",
accessToken);
if (!string.IsNullOrEmpty(nextOpenId))
{
url += "&next_openid=" + nextOpenId;
}
return HttpUtility.Get.GetJson<OpenIdResultJson>(url);
}
}
}
分组接口
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/Groups
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
/// <summary>
/// 用户组接口
/// </summary>
public static class Groups
{
/// <summary>
/// 创建分组
/// </summary>
/// <returns></returns>
public static CreateGroupResult Create(string accessToken, string name)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/groups/create?access_token={0}";
var data = new
{
group = new
{
name = name
}
};
return CommonJsonSend.Send<CreateGroupResult>(accessToken, urlFormat, data);
}
/// <summary>
/// 发送文本信息
/// </summary>
/// <param name="accessToken"></param>
/// <returns></returns>
public static GroupsJson Get(string accessToken)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/groups/get?access_token={0}";
var url = string.Format(urlFormat, accessToken);
return HttpUtility.Get.GetJson<GroupsJson>(url);
}
/// <summary>
/// 获取用户分组
/// </summary>
/// <param name="accessToken"></param>
/// <param name="openId"></param>
/// <returns></returns>
public static GetGroupIdResult GetId(string accessToken, string openId)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/groups/getid?access_token={0}";
var data = new { openid = openId };
return CommonJsonSend.Send<GetGroupIdResult>(accessToken, urlFormat, data);
}
/// <summary>
/// 创建分组

public static WxJsonResult Update(string accessToken, int id, string name)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/groups/update?access_token={0}";
var data = new
{
group = new
{
id = id,
name = name
}
};
return CommonJsonSend.Send(accessToken, urlFormat, data);
}
/// <summary>
/// 移动用户分组
/// </summary>
/// <param name="accessToken"></param>
/// <param name="openId"></param>
/// <param name="toGroupId"></param>
/// <returns></returns>
public static WxJsonResult MemberUpdate(string accessToken, string openId, int toGroupId)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/groups/members/update?access_token={0}";
var data = new
{
openid = openId,
to_groupid = toGroupId
};
return CommonJsonSend.Send(accessToken, urlFormat, data);
}
}
}
客服接口
说明一下，这里的客服接口和之前的“多客服”是有差别的，之前介绍的多客服是把用户对话状态切换到多客服客，消息发送到专门的多客服户端，这个对话是由用户主动发起的。而这里的“客服”实际上是指在任意时间，主动推送消息给指定过的用户（用户在48小时内有过互动），对话不需要由用户主动发起。
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/Custom
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
/// <summary>
/// 客服接口
/// </summary>
public static class Custom
{
private const string URL_FORMAT = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={0}";

{
var data = new

touser = openId,
msgtype = "text",

}
};
return CommonJsonSend.Send(accessToken, URL_FORMAT, data);
}
/// <summary>

media_id = mediaId,
thumb_media_id = thumbMediaId

{
var data = new

touser = openId,
msgtype = "news",
news = new
{
articles = articles.Select(z => new
{
title = z.Title,
description = z.Description,
url = z.Url,
picurl = z.PicUrl//图文消息的图片链接，支持JPG、PNG格式，较好的效果为大图640*320，小图80*80
}).ToList()
}
};
return CommonJsonSend.Send(accessToken, URL_FORMAT, data);
}
}
}
群发接口
这里的群发效果和登录微信后台群发是一样的。
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/GroupMessage
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
/// <summary>
/// 高级群发接口
/// </summary>
public static class GroupMessage
{
/// <summary>
/// 根据分组进行群发
///
/// 请注意：
/// 1、该接口暂时仅提供给已微信认证的服务号
/// 2、虽然开发者使用高级群发接口的每日调用限制为100次，但是用户每月只能接收4条，请小心测试
/// 3、无论在公众平台网站上，还是使用接口群发，用户每月只能接收4条群发消息，多于4条的群发将对该用户发送失败。
///
/// </summary>
/// <param name="accessToken"></param>
/// <param name="groupId">群发到的分组的group_id</param>
/// <param name="mediaId">用于群发的消息的media_id</param>
/// <returns></returns>
public static SendResult SendGroupMessageByGroupId(string accessToken, string groupId, string mediaId)
{
const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/mass/sendall?access_token={0}";
var data = new
{
filter = new
{
group_id = groupId
},
mpnews = new
{
media_id = mediaId
},
msgtype = "mpnews"
};
return CommonJsonSend.Send<SendResult>(accessToken, urlFormat, data);
}
/// <summary>
/// 根据OpenId进行群发
/// </summary>
/// <param name="accessToken"></param>

public static SendResult SendGroupMessageByOpenId(string accessToken, string mediaId, params string[] openIds)
{
const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/mass/send?access_token={0}";
var data = new
{
touser = openIds,
mpnews = new
{
media_id = mediaId
},
msgtype = "mpnews"
};
return CommonJsonSend.Send<SendResult>(accessToken, urlFormat, data);
}
/// <summary>
/// 删除群发消息
/// </summary>
/// <param name="accessToken"></param>
/// <param name="mediaId">发送出去的消息ID</param>
/// <returns></returns>
public static WxJsonResult DeleteSendMessage(string accessToken, string mediaId)
{
//官方API地址为https://api.weixin.qq.com//cgi-bin/message/mass/delete?access_token={0}，应该是多了一个/
const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/mass/delete?access_token={0}";
var data = new
{
msgid = mediaId
};
return CommonJsonSend.Send<WxJsonResult>(accessToken, urlFormat, data);
}
}
}
多媒体接口
多媒体接口用于上传图片、语音、图文消息等多媒体信息，一般这些信息都可以用于客服接口或群发。
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/Media
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
//接口详见：http://mp.weixin.qq.com/wiki/index.php?title=%E4%B8%8A%E4%BC%A0%E4%B8%8B%E8%BD%BD%E5%A4%9A%E5%AA%92%E4%BD%93%E6%96%87%E4%BB%B6
/// <summary>
/// 多媒体文件接口
/// </summary>
public static class Media
{
/// <summary>
/// 上传媒体文件
/// </summary>
/// <param name="accessToken"></param>
/// <param name="type"></param>
/// <param name="file"></param>
/// <returns></returns>
public static UploadResultJson Upload(string accessToken, UploadMediaFileType type, string file)
{
var url = string.Format("http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token={0}&type={1}", accessToken, type.ToString());
var fileDictionary = new Dictionary<string, string>();
fileDictionary["media"] = file;
return HttpUtility.Post.PostFileGetJson<UploadResultJson>(url, null, fileDictionary, null);
}
/// <summary>
/// 下载媒体文件
/// </summary>
/// <param name="accessToken"></param>
/// <param name="mediaId"></param>
/// <param name="stream"></param>
public static void Get(string accessToken, string mediaId, Stream stream)
{
var url = string.Format("http://file.api.weixin.qq.com/cgi-bin/media/get?access_token={0}&media_id={1}",
accessToken, mediaId);
HttpUtility.Get.Download(url, stream);
}
/// <summary>
/// 上传图文消息素材
/// </summary>
/// <param name="accessToken">Token</param>
/// <param name="news">图文消息组</param>
/// <returns></returns>
public static UploadMediaFileResult UploadNews(string accessToken, params NewsModel[] news)
{
const string urlFormat = "https://api.weixin.qq.com/cgi-bin/media/uploadnews?access_token={0}";
var data = new
{
articles = news
};
return CommonJsonSend.Send<UploadMediaFileResult>(accessToken, urlFormat, data);
}
}
}
二维码接口
使用二维码接口可以方便地创建和验证二维码。所创建的二维码用于让用户关注或识别扫描的场景。
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/QrCode
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
//API：http://mp.weixin.qq.com/wiki/index.php?title=%E7%94%9F%E6%88%90%E5%B8%A6%E5%8F%82%E6%95%B0%E7%9A%84%E4%BA%8C%E7%BB%B4%E7%A0%81
/// <summary>
/// 二维码接口
/// </summary>
public static class QrCode
{
/// <summary>
/// 创建二维码
/// </summary>
/// <param name="expireSeconds">该二维码有效时间，以秒为单位。 最大不超过1800。0时为永久二维码</param>
/// <param name="sceneId">场景值ID，临时二维码时为32位整型，永久二维码时最大值为1000</param>
/// <returns></returns>
public static CreateQrCodeResult Create(string accessToken, int expireSeconds, int sceneId)
{
var urlFormat = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token={0}";
object data = null;
if (expireSeconds > 0)
{
data = new
{
expire_seconds = expireSeconds,
action_name = "QR_SCENE",
action_info = new
{
scene = new
{
scene_id = sceneId
}
}
};
}
else
{
data = new
{
action_name = "QR_LIMIT_SCENE",
action_info = new
{
scene = new
{
scene_id = sceneId
}
}
};
}
return CommonJsonSend.Send<CreateQrCodeResult>(accessToken, urlFormat, data);
}
/// <summary>
/// 获取二维码（不需要AccessToken）
/// 错误情况下（如ticket非法）返回HTTP错误码404。
/// </summary>
/// <param name="ticket"></param>
/// <param name="stream"></param>
public static void ShowQrCode(string ticket, Stream stream)
{
var urlFormat = "https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket={0}";
HttpUtility.Get.Download(string.Format(urlFormat, ticket), stream);
}
}
}
模板消息接口
模板消息类似于短信通知，它遵循一定的模板格式（和图文信息等不一样），不是每个通过验证的服务号都可以获取。
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/TemplateMessage
源代码中相关方法如下：
namespace Senparc.Weixin.MP.AdvancedAPIs
{
/// <summary>
/// 模板消息接口
/// </summary>
public static class Template
{
public static WxJsonResult SendTemplateMessage<T>(string accessToken, string openId, string templateId, string topcolor, T data)
{
const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token={0}";
var msgData = new TempleteModel()
{
template_id = templateId,
topcolor = topcolor,
touser = openId,
data = data
};
return CommonJsonSend.Send<WxJsonResult>(accessToken, urlFormat, msgData);
}
}
}
OAuth2.0接口
OAuth接口用于安全验证使用微信内嵌浏览器访问的用户的身份（例如获取OpenId）
源文件文件夹：Senparc.Weixin.MP/AdvancedAPIs/OAuth
相比其他接口OAuth2.0略微复杂，相关内容将在下一篇专门进行介绍：《Senparc.Weixin.MP SDK 微信公众平台开发教程（十二）：OAuth2.0说明》
