微信平臺接入web頁面功能接口 web

今年因工做須要，經過微信平臺接入公司的Wap頁面，回憶下，記錄內容，方面之後使用。json

1.成爲開發者後，你纔可使用公衆平臺的開發功能。須要填寫URL和ToKen,接口配置信息。api

2.服務器端開發以下接口，等待微信服務器調用。數組

URL：緩存

用來接收微信服務器數據的接口URL，安全

http://192.168.0.199/weixin/****.ashx（該地址不固定，能夠由後臺開發者根據實際狀況本身擬定，但只支持80端口）服務器

Token：微信

開發者能夠任意擬定，已備用做生成簽名（該Token會和接口URL中包含的Token進行比對，從而驗證安全性）。app

請求方式：ide

Get

接收參數：

參數	描述
signature	微信加密簽名，signature結合了開發者填寫的token參數和請求中的timestamp參數、nonce參數。
timestamp	時間戳
nonce	隨機數
echostr	隨機字符串

響應微信服務器：

開發者經過檢驗signature對請求進行校驗（下面有校驗方式）。若確認這次GET請求來自微信服務器，請原樣返回echostr參數內容，則接入生效，不然接入失敗。

加密/校驗流程以下：

1. 將token、timestamp、nonce三個參數進行字典序排序

2. 將三個參數字符串拼接成一個字符串進行sha1加密

3. 開發者得到加密後的字符串可與signature對比，標識該請求來源於微信

3. 在公衆平臺網站的高級功能 – 開發模式頁，點擊「成爲開發者」按鈕，填寫URL和Token。提交信息後，微信服務器將發送GET請求到填寫的URL上，進行接入驗證。

4.C#代碼

object signature = context.Request.QueryString["signature"]; 
    object timestamp = context.Request.QueryString["timestamp"];
    object nonce = context.Request.QueryString["nonce"];
    object echoStr = context.Request.QueryString["echoStr"]; 
    if (signature != null && signature.ToString() != "" && timestamp != null && timestamp.ToString() != "" && nonce != null && nonce.ToString() != "" && echoStr != null && echoStr.ToString() != "")
            {
                CheckSignature(signature.ToString(), timestamp.ToString(), nonce.ToString(), echoStr.ToString(), token);
            }

        /// <summary>
        /// 驗證微信 字典排序後 返回隨機數
        /// </summary>
        /// 將token、timestamp、nonce三個參數進行字典排序
        /// 將三個參數字符串拼接成一個字符串sha1加密
        /// 獲取加密後的字符串可與signature 對比 若是爲true則返回隨數
        /// <returns></returns>
        private void CheckSignature(string signature, string timestamp, string nonce, string echoStr, string Token)
        {

            string[] ArrTmp = { Token, timestamp, nonce };
            Array.Sort(ArrTmp);     //首º¡Á先¨¨字Á?典Ì?排?序¨°
            string tmpStr = string.Join("", ArrTmp);
            tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");  //sha1
            tmpStr = tmpStr.ToLower();
            if (tmpStr == signature)
            {
                if (!string.IsNullOrEmpty(echoStr))
                {
                    System.Web.HttpContext.Current.Response.Write(echoStr);
                    System.Web.HttpContext.Current.Response.End();
                }
            }
        }

5.驗證經過後，就能夠獲得appid 和secret參數了

6.建立菜單

（1）目前自定義菜單最多包括3個一級菜單，每一個一級菜單最多包含5個二級菜單。一級菜單最多4個漢字，二級菜單最多7個漢字，多出來的部分將會以「...」代替。請注意，建立自定義菜單後，因爲微信客戶端緩存，須要24小時微信客戶端纔會展示出來。建議測試時能夠嘗試取消關注公衆帳號後再次關注，則能夠看到建立後的效果。

目前自定義菜單接口可實現兩種類型按鈕，以下：

click：

用戶點擊click類型按鈕後，微信服務器會經過消息接口推送消息類型爲event 的結構給開發者（參考消息接口指南），而且帶上按鈕中開發者填寫的key值，開發者能夠經過自定義的key值與用戶進行交互；

view：

用戶點擊view類型按鈕後，微信客戶端將會打開開發者在按鈕中填寫的url值（即網頁連接），達到打開網頁的目的，建議與網頁受權獲取用戶基本信息接口結合，得到用戶的登入我的信息。

（2）示例：

接口調用請求說明

http請求方式：POST（請使用https協議）

https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

請求示例

     "button":[

          "type":"click",

          "name":"今日歌曲",

          "key":"V1001_TODAY_MUSIC"

},

           "type":"click",

           "name":"歌手簡介",

           "key":"V1001_TODAY_SINGER"

},

           "name":"菜單",

           "sub_button":[

               "type":"view",

               "name":"搜索",

               "url":"http://www.soso.com/"

},

               "type":"view",

               "name":"視頻",

               "url":"http://v.qq.com/"

},

               "type":"click",

               "name":"贊一下咱們",

               "key":"V1001_GOOD"

}]

}]

參數說明

參數	是否必須	說明
button	是	一級菜單數組，個數應爲1~3個
sub_button	否	二級菜單數組，個數應爲1~5個
type	是	菜單的響應動做類型，目前有click、view兩種類型
name	是	菜單標題，不超過16個字節，子菜單不超過40個字節
key	click類型必須	菜單KEY值，用於消息接口推送，不超過128字節
url	view類型必須	網頁連接，用戶點擊菜單可打開連接，不超過256字節

返回結果

正確時的返回JSON數據包以下：

{"errcode":0,"errmsg":"ok"}

錯誤時的返回JSON數據包以下（示例爲無效菜單名長度）：

{"errcode":40018,"errmsg":"invalid button name size"}

7.接口邏輯操做統一接口

（1）菜單也能夠爲：

"\"type\":\"click\"," +

"\"name\":\"快樂每一天\"," +

"\"key\":\"yc_jbcg\""+

以xml文本形式傳遞參數
