对接微信公众平台一些问题

1.自定义菜单创建的问题
在使用微信公众平台的时候遇见的一些问题
创建菜单，微信公众平台只能创建三个菜单必须在同一个button下面
子菜单则可以创建多个最多5个

$data["button"] = array(
            array(
                "type" => "click",
                "name" => "菜单A",
                "key" => "caidan"
            ),
            array(
                "name" => "菜单B",
                "sub_button" => array(
                    array(
                        "type" => "view",
                        "name" => "搜索",
                        "url" => "http://www.baidu.com"
                    ),

                ),
            ),
            array(
                "type" => "click",
                "name" => "用户信息",
                "key" => "userdata",
            ),
        );

2. 发送至微信服务时 应该使用json 发送

$postData = json_encode($data, JSON_UNESCAPED_UNICODE);

3. 获取openid的时候需要通过开放平台获取，互动消息需要使用服务器，但是可直接发送模板消息

4. php curl get代码

public function get($url)
    {
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
        curl_setopt($curl, CURLOPT_HEADER, 0);
        curl_setopt($curl, CURLOPT_TIMEOUT, 10);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
        $data = curl_exec($curl);
        return $data;
    }

5. php curl post代码

public function post($url, $filedata)
    {
        $curl = curl_init();
        if (class_exists('./CURLFile')) {
            curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
        }

        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
        if (!empty($filedata)) {
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $filedata);
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($curl);
        curl_close($curl);
        return $output;
    }
// 接受消息
$json = file_get_contents("php://input");
$json = json_decode($json, true);
print_r($json);
