本项目基于微信官方WP8 SDK编写，适用于Windows 10 UWP应用和WP8.1 WinRT应用。UWP项目中还提供WeChatSDK.Extensions，封装部分微信Open API，方便在使用SDK登录授权后，获取用户基本资料等需求。
本项目仅供学习交流参考。
访问微信开放平台注册应用，SDK使用方法同官方文档基本一致
分享文本消息
try
{
var scene = SendMessageToWX.Req.WXSceneTimeline;
var message = new WXTextMessage
{
Title = "Sharing a text title!",
Text = "This is text content",
Description = "This is a text message.这是一个文本消息。",
ThumbData = null
};
SendMessageToWX.Req req = new SendMessageToWX.Req(message, scene);
IWXAPI api = WXAPIFactory.CreateWXAPI("[YOUR APP ID]");
var isValid = await api.SendReqAsync(req);
}
catch (WXException ex)
{
Debug.WriteLine(ex.Message);
}
分享图片消息
try
{
var scene = SendMessageToWX.Req.WXSceneTimeline;
var file = await Package.Current.InstalledLocation.GetFileAsync("1.png");
using (var stream = await file.OpenReadAsync())
{
var pic = new byte[stream.Size];
await stream.AsStream().ReadAsync(pic, 0, pic.Length);
var message = new WXImageMessage
{
Title = "Sharing a picture!",
Description = "This is a image message.这是一个图片消息",
ThumbData = pic,
ImageUrl = "http://tp3.sinaimg.cn/1882347990/180/5725518284/1"
};
SendMessageToWX.Req req = new SendMessageToWX.Req(message, scene);
IWXAPI api = WXAPIFactory.CreateWXAPI("[YOUR APP ID]");
var isValid = await api.SendReq(req);
}
}
catch (WXException ex)
{
Debug.WriteLine(ex.Message);
}
分享链接消息
try
{
var scene = SendMessageToWX.Req.WXSceneTimeline;
var file = await Package.Current.InstalledLocation.GetFileAsync("1.png");
using (var stream = await file.OpenReadAsync())
{
var pic = new byte[stream.Size];
await stream.AsStream().ReadAsync(pic, 0, pic.Length);
var message = new WXWebpageMessage
{
WebpageUrl = "http://www.baidu.com",
Title = "Sharing a link!",
Description = "This is a link message.这是一个链接消息",
ThumbData = pic
};
SendMessageToWX.Req req = new SendMessageToWX.Req(message, scene);
IWXAPI api = WXAPIFactory.CreateWXAPI("[YOUR APP ID]");
var isValid = await api.SendReq(req);
}
}
catch (WXException ex)
{
Debug.WriteLine(ex.Message);
}
微信登录授权
try
{
SendAuth.Req req = new SendAuth.Req("[YOUR SCOPE]", "test");
IWXAPI api = WXAPIFactory.CreateWXAPI("[YOUR APP ID]");
var isValid = await api.SendReqAsync(req);
}
catch (WXException ex)
{
Debug.WriteLine(ex.Message);
}
####分享结果回调和登录授权回调
- 打开
Pakcage.appxmanifest文件，在Extensions节点下添加文件关联协议
<Extensions>
<uap:Extension Category="windows.fileTypeAssociation">
<uap:FileTypeAssociation Name="wechat">
<uap:SupportedFileTypes>
<uap:FileType>.[YOUR APP ID]</uap:FileType>
</uap:SupportedFileTypes>
</uap:FileTypeAssociation>
</uap:Extension>
</Extensions>
- 在你的项目中，创建一个类
WeChatCallback类，继承WXEntryBasePage类，重载OnSendMessageToWXResponse方法和OnSendAuthResponse处理回调结果。 ，如
public override async void OnSendMessageToWXResponse(SendMessageToWX.Resp response)
{
base.OnSendMessageToWXResponse(response);
var dialog = new MessageDialog(response.ErrCode == 0 ? "分享成功": "分享失败");
await dialog.ShowAsync();
}
public override async void OnSendAuthResponse(SendAuth.Resp response)
{
base.OnSendAuthResponse(response);
if (response.ErrCode == 0)
{
if (!string.IsNullOrEmpty(response.Code))
{
var token = await WeChatSns.GetAccessTokenAsync(response.Code);
if (token != null)
{
var user = await WeChatSns.GetUserInfoAsync(token.AccessToken, token.OpenId);
var dialog = new MessageDialog($"name:{user.Nickname}\r\nopenid:{user.OpenId}","授权成功");
await dialog.ShowAsync();
}
}
}
else
{
var dialog = new MessageDialog("授权失败");
await dialog.ShowAsync();
}
}
- 微信处理结果点击“返回XXX（应用名）”后，会在App.xaml.cs中触发OnFileActivated事件，在事件中处理微信返回结果：
protected override void OnFileActivated(FileActivatedEventArgs args)
{
base.OnFileActivated(args);
try
{
var wechat = new WeChatCallback();
wechat.Handle(args);
}
catch (Exception)
{
// ignored
}
}
