PHP實戰(zhàn)：php微信公眾賬號開發(fā)之五個坑（二）
作者：VEPHP 時間 2017-09-25
《PHP實戰(zhàn)：php微信公眾賬號開發(fā)之五個坑（二）》要點：
本文介紹了PHP實戰(zhàn)：php微信公眾賬號開發(fā)之五個坑（二），希望對您有用。如果有疑問，可以聯(lián)系我們。
PHP編程上篇說到微信公眾賬號的幾個坑,前面五個,已經(jīng)說到菜單,寶寶繼續(xù)往下贅述了.可惜,還不知道寶寶的寶寶到底是不是心疼寶寶呢,完了,我凌亂了...?
PHP編程回到正題,我們就不吐槽其他的了,上一篇說到微信的菜單了,那么,我們現(xiàn)在說說菜單回復(fù)等等的吧.?
PHP編程菜單回復(fù)是需要處理XML文件的,我們根據(jù)微信返回的XML文件,可以得到每個微信用戶相對于微信公眾號的唯一標(biāo)識.微信公眾平臺的機制簡單的將就是我們自己輸出固定格式的xml文件,然后微信APP負(fù)責(zé)解析,得到我們想要的信息,然后對信息統(tǒng)一處理.?
PHP編程第六坑,如果你看微信文檔,那么,絕對坑死你,上圖.這里的ToUserName和FromUserName一定特么的要分清楚了,記住,千萬不要寫反了,用戶對于微信而言是A→B,那么微信對于用戶就是反著來的,貌似現(xiàn)在應(yīng)該說清楚了.

PHP編程OK,加上自己的邏輯代碼,是不是完美的實現(xiàn)了回復(fù)??
PHP編程第七坑,我真心不想計數(shù)了,你確定這個回復(fù)可以么?說真的,寶寶不確定,因為你寫了之后知道在哪里調(diào)用么,我的乖乖,尼瑪,服務(wù)器驗證通過就把回復(fù)加上去是最保險的.我已經(jīng)沒有節(jié)操了.
PHP編程接下來我們說什么呢,我們就說說獲取用戶信息這個東西吧,因為我們這些東西一般都是基于H5頁面的.所以,就要用到之前我們配置的
PHP編程
PHP編程這個東東,其實這個相對于前面的至少坑少了很多,真心的,寶寶就暫時不說他坑了.上個代碼吧.?

PHP編程我們需要調(diào)用的時候直接用里面的方法,獲取微信網(wǎng)頁授權(quán)即可,比如對于A控制器下面的B視圖要獲取授權(quán),并且要獲取用戶的相關(guān)信息,那么我們直接調(diào)用即可,如 GetCodeUrl(appid, "http://" + Url + "/A/B", "snsapi_userinfo")
PHP編程在這里我還是吐槽一下吧.?
PHP編程第八坑,微信菜單JSON的url拼接,里面的前面不是加了js驗證么,so,特么的,還是乖乖的加上http://.?
PHP編程不過這里授權(quán)之后,因為用戶的很多信息我們都要用到,這就是H5頁面?zhèn)髦档膯栴},我在項目里面用的是Session,直接寫一個公用方法,如果Session有值,則直接取值的.對于里面的一些東東,我想說明一下,并不是所有的代碼都要貼出來,我這邊的代碼只是我個人認(rèn)為需要貼出來的.所以里面的方法可能有大家看不到的,如果需要,可以留言本寶寶,謝謝.?
PHP編程
public string getSession()
{
log.Error("GetSession");
string oauthStr = "";
try
{
if (Session != null && (Session["oauthStr"] == null || string.IsNullOrEmpty(Session["oauthStr"].ToString())))
{
if (!string.IsNullOrEmpty(Request.QueryString["code"]))
{
Oauth2 oauth = new Oauth2();
string code = Convert.ToString(Request["code"]);
oauthStr = oauth.GetUserInfo(ConfigurationManager.AppSettings["AppID"],
ConfigurationManager.AppSettings["AppSecret"], code);
Session["oauthStr"] = oauthStr;
Tools.WAEntity.OAuthUser oAuthUser = new Tools.WAEntity.OAuthUser();
oAuthUser = Tools.JsonHelper.ParseFromJson<Tools.WAEntity.OAuthUser>(oauthStr);
}
return oauthStr;
}
else
{
Tools.WAEntity.OAuthUser oAuthUser = new Tools.WAEntity.OAuthUser();
oAuthUser = Tools.JsonHelper.ParseFromJson<Tools.WAEntity.OAuthUser>(Session["oauthStr"].ToString());
return Session["oauthStr"].ToString();
}
}
catch (Exception e) { log.Error(e.ToString()); return oauthStr; };
}
PHP編程然后每次遇到需要獲取信息的頁面,我一般都是調(diào)用這個就可以了.?
PHP編程基本上剩下的都是我們自己要處理的業(yè)務(wù)邏輯了,繼續(xù)說坑吧.?
PHP編程第九坑,微信上傳圖片,坑的絕對不只是自己.對于這個寶寶真的信了,不管你信不信.特么的圖片不能for循環(huán)上傳.當(dāng)然,這個只限蘋果機型,大Android還是沒有問題的.
前面說到了JS安全驗證的問題,這里就是調(diào)用這些個驗證,請求一些應(yīng)該的權(quán)限,然后獲取圖片信息等等.?
PHP編程
PHP編程放心好了,寶寶現(xiàn)在都是上圖說話,沒圖說個小弟弟呀.....?
PHP編程我們繼續(xù)回來看代碼.?
PHP編程先來個處理Json的
PHP編程
public class JsApi
{
JavaScriptSerializer Jss = new JavaScriptSerializer();
public JsApi() { }
const string URL_FORMAT_TICKET = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token={0}&type=jsapi";

/// <returns>json格式的四個參數(shù)</returns>
public string GetJsApiInfo(string Appid, string Appsecret)
{
string jsapi_ticket = "";
//ticket 緩存7200秒
if (System.Web.HttpContext.Current.Session["jsapi_ticket"] == null)
{
string ticketurl = string.Format(URL_FORMAT_TICKET, BasicApi.GetAccessToken(Appid, Appsecret));//"https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=" + GetAccessToken(Appid, Appsecret) + "&type=jsapi"
jsapi_ticket = CommonMethod.WebRequestPostOrGet(ticketurl, "");//BasicApi.GetTokenSession
System.Web.HttpContext.Current.Session["jsapi_ticket"] = jsapi_ticket;
System.Web.HttpContext.Current.Session.Timeout = 7200;
BasicApi.WriteTxt("jsapi_ticket1:" + jsapi_ticket);
}
else
{
jsapi_ticket = System.Web.HttpContext.Current.Session["jsapi_ticket"].ToString();
BasicApi.WriteTxt("jsapi_ticket2:" + jsapi_ticket);
}
Dictionary<string, object> respDic = (Dictionary<string, object>)Jss.DeserializeObject(jsapi_ticket);
jsapi_ticket = respDic["ticket"].ToString();//獲取ticket
string timestamp = CommonMethod.ConvertDateTimeInt(DateTime.Now).ToString();//生成簽名的時間戳
string nonceStr = CommonMethod.GetRandCode(16);//生成簽名的隨機串
string url = System.Web.HttpContext.Current.Request.Url.AbsoluteUri.ToString();//當(dāng)前的地址
BasicApi.WriteTxt("url:" + url);
string[] ArrayList = { "jsapi_ticket=" + jsapi_ticket, "timestamp=" + timestamp, "noncestr=" + nonceStr, "url=" + url };
Array.Sort(ArrayList);
string signature = string.Join("&", ArrayList);
signature = FormsAuthentication.HashPasswordForStoringInConfigFile(signature, "SHA1").ToLower();
string r = "{\"appId\":\"" + Appid + "\",\"timestamp\":" + timestamp + ",\"nonceStr\":\"" + nonceStr +
"\",\"signature\":\"" + signature +
"\",\"jsApiList\":[\"chooseImage\",\"previewImage\",\"uploadImage\",\"downloadImage\",\"scanQRCode\",\"onMenuShareQQ\"]}";
BasicApi.WriteTxt("r:" + r.Replace(" ", ""));
return r.Replace(" ", "");
}
}
PHP編程然后看具體調(diào)用.
PHP編程后臺代碼其實很簡單的,直接輸出配置文件,然后前臺js直接調(diào)用即可.?
PHP編程
JsApi jsApi = new JsApi();
string config = jsApi.GetJsApiInfo(appId, appSecret);
ViewBag.config = config;
PHP編程前臺代碼,其實也不難,這個有官方的例子的.?
PHP編程
<script type="text/javascript">
wx.config(@Html.Raw(ViewBag.config));//后臺傳遞的微信配置文件
wx.ready(function () {
$("#avatar").click(function () {
wx.chooseImage({
count: 1, // 圖片數(shù)量 默認(rèn)9
sizeType: ['compressed'], // 可以指定是原圖還是壓縮圖,默認(rèn)二者都有'original',
sourceType: ['album', 'camera'], // 可以指定來源是相冊還是相機,默認(rèn)二者都有
success: function (res) {
var localIds = res.localIds; // 返回選定照片的本地ID列表,localId可以作為img標(biāo)簽的src屬性顯示圖片
wx.uploadImage({
localId: '' + localIds,

success: function (res) {
serverId = res.serverId;
getWxPhoto(serverId);
}
});
}
});
});
});
wx.error(function (res) {
alert("接口驗證失敗,詳細(xì)信息：\n" + JSON.stringify(res));
});
var types = 1;
function getWxPhoto(mediaId) {
$.ajax({
async: false,

url: "/ActivityRegistration/DownloadWxPhoto",//自己的處理方法
data: { mediaId: mediaId, types: types },
success: function (data) {
$("#imageico").val(data.result);
$("#hed_pic").attr('src', ".." + data.result);
$("#hed_pic").attr('alt', "avatarImg");
}
});
}
</script>
PHP編程OK,后臺方法其實也很簡單,就是一個二進制文件處理,不對,簡單個蛋蛋,特么的,因為路徑的問題,坑了寶寶一個小時,特么的.還有這里建議,等微信圖片下載完成之后再給前臺加載圖片,保證每一個圖片都加載完成,保證后臺的圖片的上傳完成.?

PHP編程?是不是以為這就算完事了,我的乖乖,頭像上傳了,微信攝像頭也特么該調(diào)用的調(diào)用了,寶寶好幸福,寶寶也是牛人一個了,記住前面的東東,寶寶還沒有說坑呢.
來重復(fù)我們的第九個坑,特么的,你JS寫個for循環(huán)要是能循環(huán)把圖片上傳到后臺,寶寶也服氣,真的,寶寶服氣.?
PHP編程直接說吧,最后我自己想了下,也和隊友討論了下,可能是因為微信有什么驗證,導(dǎo)致之后一張圖片上傳成功之后,才能進行一張,但是我們Iphone就是特么的特例,大Android沒用問題的,就是Iphone有了問題,而且問題不小,上傳四張圖片吧,老特么是最后一張,最后,找到了萬能的網(wǎng)友,感謝你,不過寶寶已經(jīng)忘記了在哪里找到的了,尷尬了...........?

PHP編程請記住,遞歸就特么可以了.
PHP編程說到這里,寶寶已經(jīng)不想多說什么了,特么的產(chǎn)品你能不能不裝逼,你特么見過那個微信能回復(fù)一個信息直接跳轉(zhuǎn)網(wǎng)頁的,你咋不去屎呢,聯(lián)想到前幾天大阿里的月餅時間,突然感覺我們程序員挺悲劇的,成功的都是特么的產(chǎn)品,然后出問題的都是我們程序員的鍋?試問一下,這個鍋真心我們程序員該背么.?
PHP編程算了,還是不吐槽了,已經(jīng)無力了....寶寶92年降臨,現(xiàn)在確實82年的皮膚呀,唉,寶寶累了,真的.?
PHP編程順便給點H5頁面的建議吧.比如當(dāng)點擊返回鍵的時候,我們需要刷新頁面的時候,就是所謂的判斷頁面要不要刷新,這里有很多種方法,但是微信里面寶寶還是覺得這么干靠譜.?
PHP編程
<script type="text/javascript">
if (window.name != "hasLoad") {
location.reload();
window.name = "hasLoad";
} else {
window.name = "";
}
</script>
PHP編程還有,那個微信執(zhí)行完成之后想直接退出當(dāng)前界面進入微信公眾號界面的,直接調(diào)用微信的一個內(nèi)置的方法即可.記得寫到<script></script>里面.?
PHP編程WeixinJSBridge.call('closeWindow'); //這是微信關(guān)閉當(dāng)前網(wǎng)頁
PHP編程這么自信的以為自己搞定了所有,你跑呀,你要跑起來,嗯哼,別不服氣.?
PHP編程微信公眾賬號指第十坑,我自己加的,哈哈,就是前面的JS驗證的時候,你不要頭文件,怎么搞定這些事情,哈哈.是不是寶寶贏了.Oh? perfect,I like it.
