微信H5支付完整版含PHP回撥頁面
阿新 • • 發佈：2018-11-17
注意事項:
一,微信H5支付只能用在手機瀏覽器中,比如百度瀏覽器,UC瀏覽器等,不可以用在微信中,微信中只可以使用公眾號支付.要特別注意.
二,如果你的h5手機版網站加殼打包封裝成了APP,根據我們的測試,也可以使用微信h5支付.不過.據微信官方說,可能會提示商家引數格式有誤，請聯絡商家解決,原因. 當前調起H5支付的referer為空導致，一般是因為直接訪問頁面調起H5支付，請按正常流程進行頁面跳轉後發起支付，或自行抓包確認referer值是否為空如果是在封裝的APP裡調起H5支付，需要在webview中手動設referer，如(Map extraHeaders = new HashMap();ex
traHeaders.put(“Referer”, “商戶申請H5時提交的授權域名”);//例如 http://www.baidu.com ))
以上是,微信官方的說明,如果你的網站需要打包成APP.可以具體諮詢對方技術人員,打包後,是否影響h5支付.以免糾紛.
三,微信支付最麻煩的就是簽名失敗.很多時候與網站中的中文編碼有關,注意轉碼.
四,支付檔案需放到支付授權目錄下，可以在微信支付商戶平臺->產品中心->開發配置中設定。
程式碼如下,本文的所有程式碼預設放在m\user\wxpay目錄中,
一.wxpay目錄中的H5.config.php 配置檔案,這個檔案一般是後臺儲存後.自動生成的檔案.內容為
<? return array( 'APPID' => 'wxc35486954cde','MCHID' => '1496515882','KEY' => '6ac2b9e536763299','APPSECRET' => '6ac2b9e53676328c46e','SSLCERT_PATH' => '','SSLKEY_PATH' => '',' CURL_PROXY_HOST' => '','CURL_PROXY_PORT' => 0,'REPORT_LEVENL' => 1);?>
三,h5_pay.php 支付檔案.本檔案中,需要生成訂單並儲存到你的資料庫中,並跳轉到微信,進行支付.
<?php
