CI-Framework WeChat-Entwicklung – benutzerdefiniertes Menü

Implementierte die benutzerdefinierte Menüfunktion unter dem CI-Framework. Die Implementierung von access_token ist übrigens auch enthalten

Die oben genannten sind verschiedene Methoden im Modell.

Die Tabellenstruktur der Datenbank ist wie folgt, mit Anweisungen zum Erstellen von Tabellen.

	Field	Type	Comment
主键	id	int(11) NOT NULL
	content	varchar(20) NULL	<内容>
	pid	int(11) NULL	<父类ID>
	menutype	enum('click','view','scancode_push','scancode_waitmsg','pic_sysphoto','pic_photo_or_album','pic_weixin','location_select') NULL	消息类型
	url	varchar(200) NULL	链接地址
	clickkey	varchar(20) NULL	事件KEY
	menuorder	int(11) NULL	排序
	submenu	tinyint(2) NULL	<是否是子菜单>

Das Folgende ist die Methode zum Erhalten von Token, die unter system/core/common.php geschrieben ist. Tatsächlich muss es gesalzen werden, sonst werden ekelhafte Menschen ekelhafte Dinge tun.

<span>function</span><span> get_access_token(){
        </span><span>//</span><span>从微信服务器获取access_token  并保留一个小时</span>
        <span>$old_filename</span> = APPPATH."cache/".<span>md5</span>(<span>date</span>("YmdH",<span>time</span>()-3600)).".php"<span>;
        @</span><span>unlink</span>(<span>$old_filename</span><span>);

            </span><span>$res</span> = "<?php return ".<span>var_export</span>(json_decode(<span>$access_token</span>,1),1).";"<span>;
            </span><span>file_put_contents</span>(<span>$filename</span>,<span>$res</span><span>);

        }

    }</span>

Ich werde nicht über die vorherige Menüverwaltung schreiben. Sie verwaltet lediglich die Daten in dieser Tabelle und stellt sicher, dass es kein Problem mit den Daten in der Datentabelle gibt.

Nur ​​

im Controller erforderlich

$this->load->library("Makemenu");

Dann rufen Sie $this->makemenu->dolist();

auf

wird an den WeChat-Server übertragen. Sie müssen außerdem darauf achten, zwei Konstanten APPID und APPSECRET in der Eintragsdatei zu definieren.

Ich habe es für alle veröffentlicht, ich hoffe, dass es nützlich sein wird, und ich werde eine Sicherungskopie für mich selbst erstellen.

Das Obige stellt das benutzerdefinierte Entwicklungsmenü des CI-Frameworks WeChat vor und hoffe, dass es für Freunde hilfreich ist, die sich für PHP-Tutorials interessieren.
