先說怎麼用,然後使用成功了自己研究代碼,驅動式學習多好。
-
首先將這個PHP程序的文件放在你 自己的服務器裏面
注意php程序裏的APP_ID的值改成你自己的appid。還有APP_SECRET 的值改成你自己的appSecret。還有記好配置的token令牌,等會配置用到。 -
然後打開消息推送
在小程序後臺“開發”->“開發設置”->下拉有一個消息推送,打開。
服務器地址填寫這個PHP文件的位置https://**********.php
TOKEN(令牌) ----這裏隨便寫,反正與PHP程序裏的開頭那裏我 的是dertertsdf
define(“TOKEN”,“dertertsdf”);//自己設置的Token
密鑰隨機生成
然後模式選兼容模式
接受類型選“XML”
這是配置,然後如果你急着提交會發現“taken(令牌) 失效”。。。。。就對了 -
驗證
在250行左右有一個代碼,這是驗證用的,因爲當你打開消息推送的時候騰訊的服務器會給你寫的地址發送一個請求進行驗證只有你返回正確的信息才能驗證成功,提交纔不會出現“taken(令牌) 失效”字樣。然後纔會提交成功,所以當提交時不要註釋
PS:建議把綁定的客服都解綁,因爲我發現有時候會出現bug,會把用戶聯繫 客服的消息轉發給客服了不發送給服務器也就是自動回覆那裏收不到。
//注意:第一步驗證時打開,驗證完成之後就可以註釋了
//$wechatObj->isValid();
- 修改
順利完成了上面的步驟後你打開客服應該會有自動打招呼了。
然後就自己看代碼發揮了,對應封裝一個$data變量調用官方文檔說的發送接口就可以了
如果想發送圖片,需要先把圖片發送給騰訊服務器,然後騰訊服務器會返回一個媒體的ID,用這個ID調用發送接口就可以了。程序裏我也寫好了輸入上傳圖片地址返回ID的函數了。
不過我偷懶直接調用系統指令curl,所以需要PHP的shell_exec()這個函數。爲了安全起見這個函數一般默認禁用的,所以需要在php配置文件裏該一下,百度就可以。over
下面時所有代碼。可以直接複製粘貼用【手動滑稽】

define("TOKEN","dertertsdf");//自己設置的Token

const APP_SECRET = '017ec3*****************';//你自己生成的appSecret
