c#.net微信公眾賬號接口開發(fā)

1、 c#.net 微信公眾賬號接口開發(fā)微信越來越火，微信公眾平臺成為開發(fā)成新寵，本文用c#.net開發(fā)微信公眾信號接口。微信接口地址代碼: weixin _wx = new weixin(); string poststr = ; if (request.httpmethod.tolower() = post) stream s = system.web.httpcontext.current.request.inputstream; byte b = new bytes.length; s.read(b, 0, (int)s.length); poststr = encoding.utf8.g

2、etstring(b); if (!string.isnullorempty(poststr) /請求處理 _wx.handle(poststr); else _wx.auth(); 微信處理類：public class weixin private string token = weixin_token; /換成自己的token public void auth() string echostr = system.web.httpcontext.current.request.querystringechostr; if (checksignature() if (!string.isnul

3、lorempty(echostr) system.web.httpcontext.current.response.write(echostr); system.web.httpcontext.current.response.end(); public void handle(string poststr) /封裝請求類 xmldocument doc = new xmldocument(); doc.loadxml(poststr); xmlelement rootelement = doc.documentelement; xmlnode msgtype = rootelement.se

4、lectsinglenode(msgtype); requestxml requestxml = new requestxml(); requestxml.tousername = rootelement.selectsinglenode(tousername).innertext; requestxml.fromusername = rootelement.selectsinglenode(fromusername).innertext; requestxml.createtime = rootelement.selectsinglenode(createtime).innertext; r

5、equestxml.msgtype = msgtype.innertext; if (requestxml.msgtype = text) requestxml.content = rootelement.selectsinglenode(content).innertext; else if (requestxml.msgtype = location) requestxml.location_x = rootelement.selectsinglenode(location_x).innertext; requestxml.location_y = rootelement.selectsi

6、nglenode(location_y).innertext; requestxml.scale = rootelement.selectsinglenode(scale).innertext; requestxml.label = rootelement.selectsinglenode(label).innertext; else if (requestxml.msgtype = image) requestxml.picurl = rootelement.selectsinglenode(picurl).innertext; /回復消息 responsemsg(requestxml);

7、/ / 驗證微信簽名 / / * 將token、timestamp、nonce三個參數(shù)進行字典序排序 / * 將三個參數(shù)字符串拼接成一個字符串進行sha1加密 / * 開發(fā)者獲得加密后的字符串可與signature對比，標識該請求來源于微信。 / private bool checksignature() string signature = system.web.httpcontext.current.request.querystringsignature; string timestamp = system.web.httpcontext.current.request.querystr

8、ingtimestamp; string nonce = system.web.httpcontext.current.request.querystringnonce; string arrtmp = token, timestamp, nonce ; array.sort(arrtmp); /字典排序 string tmpstr = string.join(, arrtmp); tmpstr = formsauthentication.hashpasswordforstoringinconfigfile(tmpstr, sha1); tmpstr = tmpstr.tolower(); i

9、f (tmpstr = signature) return true; else return false; / / 回復消息(微信信息返回) / / private void responsemsg(requestxml requestxml) try string resxml = ; mijiya mi = new mijiya(requestxml.content,requestxml.fromusername); if (requestxml.msgtype = text) /在這里執(zhí)行一系列操作，從而實現(xiàn)自動回復內(nèi)容. string _remsg = mi.getremsg();

10、if (mi.msgtype = 1) resxml = + convertdatetimeint(datetime.now) + 2; resxml += mi.getrepic(requestxml.fromusername); resxml += 1; else resxml = + convertdatetimeint(datetime.now) + 1; else if (requestxml.msgtype = location) string city = getmapinfo(requestxml.location_x, requestxml.location_y); if (

11、city = 0) resxml = + convertdatetimeint(datetime.now) + 1; else resxml = + convertdatetimeint(datetime.now) + 1; else if (requestxml.msgtype = image) resxml = + convertdatetimeint(datetime.now) + 1; /返回10以內(nèi)條 /int size = 10; /resxml = + convertdatetimeint(datetime.now) + + size + ; /list list = new l

12、ist(); /假如有20條查詢的返回結(jié)果 /for (int i = 0; i 20; i+) / / list.add(1); / /string piclist = new string /abstract_pencil_scribble_background_vector_main.jpg, /balloon_tree.jpg, /bloom.jpg, /colorful_flowers.jpg, /colorful_summer_flower.jpg, /fall.jpg, /fall_tree.jpg, /growing_flowers.jpg, /shoes_illustrati

13、on.jpg, /splashed_tree.jpg ; /for (int i = 0; i size & i list.count; i+) / / resxml += ; / /resxml += 1; else if (wx_tmsg.getmsgcount(requestxml.fromusername) = 0) resxml = + convertdatetimeint(datetime.now) + 1; else resxml = + convertdatetimeint(datetime.now) + 1; /writetxt(resxml); system.web.htt

14、pcontext.current.response.write(resxml); writetodb(requestxml, resxml,mi.pid); catch (exception ex) /writetxt(異常： + ex.message + struck: + ex.stacktrace.tostring(); wx_logs.myinsert(異常： + ex.message + struck: + ex.stacktrace.tostring(); / / unix時間轉(zhuǎn)換為datetime / / / private datetime unixtimetotime(str

15、ing timestamp) datetime dtstart = timezone.currenttimezone.tolocaltime(new datetime(1970, 1, 1); long ltime = long.parse(timestamp + 0000000); timespan tonow = new timespan(ltime); return dtstart.add(tonow); / / datetime轉(zhuǎn)換為unixtime / / / private int convertdatetimeint(system.datetime time) system.da

16、tetime starttime = timezone.currenttimezone.tolocaltime(new system.datetime(1970, 1, 1); return (int)(time - starttime).totalseconds; / / 調(diào)用百度地圖，返回坐標信息 / / 經(jīng)度 / 緯度 / public string getmapinfo(string x, string y) try string res = string.empty; string parame = string.empty; string url = http:/maps.goog

17、/maps/api/geocode/xml; parame = latlng= + x + , + y + &language=zh-cn&sensor=false;/此key為個人申請 res = webrequestpost(url, parame); xmldocument doc = new xmldocument(); doc.loadxml(res); xmlelement rootelement = doc.documentelement; string status = rootelement.selectsinglenode(status).innerte

18、xt; if (status = ok) /僅獲取城市 xmlnodelist xmlresults = rootelement.selectsinglenode(/geocoderesponse).childnodes; for (int i = 0; i xmlresults.count; i+) xmlnode childnode = xmlresultsi; if (childnode.name = status) continue; string city = 0; for (int w = 0; w childnode.childnodes.count; w+) for (int

19、q = 0; q childnode.childnodesw.childnodes.count; q+) xmlnode childetwo = childnode.childnodesw.childnodesq; if (childetwo.name = long_name) city = childetwo.innertext; else if (childetwo.innertext = locality) return city; return city; catch (exception ex) /writetxt(map異常: + ex.message.tostring() + s

20、truck: + ex.stacktrace.tostring(); return 0; return 0; / / post 提交調(diào)用抓取 / / 提交地址 / 參數(shù) / string public string webrequestpost(string url, string param) byte bs = system.text.encoding.utf8.getbytes(param); httpwebrequest req = (httpwebrequest)httpwebrequest.create(url + ? + param); req.method = post; re

21、q.timeout = 120 * 1000; req.contenttype = application/x-www-form-urlencoded; req.contentlength = bs.length; using (stream reqstream = req.getrequeststream() reqstream.write(bs, 0, bs.length); reqstream.flush(); using (webresponse wr = req.getresponse() /在這里對接收到的頁面內(nèi)容進行處理 stream strm = wr.getresponses

22、tream(); streamreader sr = new streamreader(strm, system.text.encoding.utf8); string line; system.text.stringbuilder sb = new system.text.stringbuilder(); while (line = sr.readline() != null) sb.append(line + system.environment.newline); sr.close(); strm.close(); return sb.tostring(); private void w

23、ritetodb(requestxml requestxml,string _xml,int _pid) wx_tmsg wx = new wx_tmsg(); wx.addnew(); wx.fromusername = requestxml.fromusername; wx.tousername = requestxml.tousername; wx.msgtype = requestxml.msgtype; wx.msg = requestxml.content; wx.creatime = requestxml.createtime; wx.location_x = requestxm

24、l.location_x; wx.location_y = requestxml.location_y; wx.label = requestxml.label; wx.scale = requestxml.scale; wx.picurl = requestxml.picurl; wx.reply = _xml; wx.pid = _pid; try wx.update(); catch (exception ex) wx_logs.myinsert(ex.message); /ex.message; /微信請求類 public class requestxml private string
