Acquiring several ways applet code / two-dimensional code applet

In two ways:

One is a small program code,

One is the two-dimensional code.

	Applet code	Applet two-dimensional code

interface	getwxacode (Interface A)	getwxacodeunlimit（B）	createwxaqrcode（C）
the term	Permanent	Permanent	Permanent
Quantity	A total of 100,000 C interface	unlimited	A total of 100,000 interface
Parameter Description	longer path parameters, the maximum 128 bytes. Such as: Incoming "foo = bar?"	You can not carry parameters (parameters, please put scene field) call frequency: 5000 times / minute	longer path parameters, the maximum 128 bytes.
parameter	path (required): Go to page width: the width of the applet code	scene (required): the above mentioned id = 261 & l_id = 598 Page: to enter the page, not with parameters	path (required): Go to page width: the width of the two-dimensional code
Successful return value	Return to image binary content	Return to image binary content	Return to image binary content

 

 

Interface B (applet code) is called:

        $url = 'https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=' . $access_token;

        $data = array();

        $data["scene"] = $scene;    // $scene : id=261&s_id=5758&l_id=598

        $data["page"] = $page;

        $data["width"] = $width;

        $json_data = json_encode($data);

        $return = $this->request_post($url, $json_data);

         // will generate a small program code into the appropriate folder

        $imgname = time() . rand(10000, 99999) . '.jpg';

        file_put_contents(IA_ROOT . "/upload/" . $imgname, $return);

 

Interface C (two-dimensional code) is called:

$url = 'https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token=' . $access_token;

            $data = array();

            $data["path"] = "/home/index/index?id=" . $id;

            $data["width"] = 300;

            $json_data = json_encode($data);

            $return = $this->request_post($url, $json_data);
