這篇文章主要為大家詳細(xì)解析了微信公眾平臺(tái)開(kāi)發(fā)之語(yǔ)音識(shí)別.Net代碼,感興趣的小伙伴們可以參考一下
語(yǔ)音識(shí)別這個(gè)功能屬于高級(jí)功能,必須微信實(shí)名認(rèn)證后才能實(shí)現(xiàn),認(rèn)證費(fèi)用300元/年,如果你作為開(kāi)發(fā)者可以申請(qǐng)測(cè)試帳號(hào),也是可以的。首先建立一個(gè)微信消息類(lèi),這個(gè)類(lèi)比之前多了一個(gè)屬性。
class wxmessage
{
public string FromUserName { get; set; }
public string ToUserName { get; set; }
public string MsgType { get; set; }
public string EventName { get; set; }
public string Content { get; set; }
public string Recognition { get; set; }
public string EventKey { get; set; }
}
語(yǔ)音識(shí)別是微信自帶的功能,非常強(qiáng)大無(wú)需我們做過(guò)多的操作:
protected void Page_Load(object sender, EventArgs e)
{
wxmessage wx = GetWxMessage();
string res = "";
if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")
{//剛關(guān)注時(shí)的時(shí)間,用于歡迎詞
string content = "";
content = "/:rose歡迎北京永杰友信科技有限公司/:rose\n直接回復(fù)“你好”";
res = sendTextMessage(wx, content);
}
else
{
if (wx.MsgType == "text" && wx.Content == "你好")
{
res = sendTextMessage(wx, "你好,歡迎使用北京永杰友信科技有限公司公共微信平臺(tái)!");
}
else if (wx.MsgType == "voice")//識(shí)別消息類(lèi)型為語(yǔ)音
{
res = sendTextMessage(wx, wx.Recognition);//wx.Recognition就是語(yǔ)音識(shí)別的結(jié)果了,我們直接引用,以文本形式反饋就OK了
}
else
{
res = sendTextMessage(wx, "你好,未能識(shí)別消息!");
}
}
Response.Write(res);
}
private wxmessage GetWxMessage()
{
wxmessage wx = new wxmessage();
StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8);
XmlDocument xml = new XmlDocument();
xml.Load(str);
wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText;
wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText;
wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText;
if (wx.MsgType.Trim() == "text")
{
wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText;
}
if (wx.MsgType.Trim() == "event")
{
wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;
}
if (wx.MsgType.Trim() == "voice")//如果是語(yǔ)音消息的話就把識(shí)別結(jié)果賦值給實(shí)體類(lèi)的相應(yīng)屬性Recognition
{
wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;
}
return wx;
}
///
/// 發(fā)送文字消息
///
/// 獲取的收發(fā)者信息
/// 內(nèi)容
///
private string sendTextMessage(wxmessage wx, string content)
{
string res = string.Format(@" ",
wx.FromUserName, wx.ToUserName, DateTime.Now, content);
return res;
}
