      微信公眾號(hào)開發(fā)過程中,都是使用自有服務(wù)器,所以我們需要對(duì)現(xiàn)有公眾號(hào)進(jìn)行配置,才能將公眾號(hào)中的消息轉(zhuǎn)發(fā)到自有服務(wù)器上,但很多時(shí)候,我們?cè)诠娞?hào)平臺(tái)服務(wù)器配置已經(jīng)填寫正確的信息,提交確認(rèn)信息的時(shí)候,總是提示:token驗(yàn)證失敗,很是惱火,借助以下php代碼,可快速驗(yàn)證服務(wù)器令牌(Token)的有效性。

      微信公眾號(hào)token驗(yàn)證php代碼如下:
