1、获取access_token
2、获取图文消息media_id
3、确定文本回复key,构建菜单json字符串
4、请求菜单创建接口
1、获取access_token
方便起见,用微信公众平台接口调试工具(http://mp.weixin.qq.com/debug?token=1606511159&lang=zh_CN)获取access_token
获取过程可能会遇到白名单问题,在公众号开发基本配置中临时修改下白名单,不出意外access_token获取成功
2、因菜单包含图文消息菜单,需获取图文消息media_id,方便起见利用postman调用接口获取。(上述第一步获取access_token也可以直接用postman)
调试公众号POST请求(获得后台素材media_id)
接口地址
http请求方式: POST
https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=ACCESS_TOKEN
参数说明
参数 | 是否必须 | 说明 |
---|---|---|
type | 是 | 素材的类型,图片(image)、视频(video)、语音 (voice)、图文(news) |
offset | 是 | 从全部素材的该偏移位置开始返回,0表示从第一个素材 返回 |
count | 是 | 返回素材的数量,取值在1到20之间 |
将刚刚获得的基础token拼入接口地址填入postman 选择请求方式为POST
添加请求参数
返回结果中获取media_id
3、包含直接回复文本的菜单,确定key,构建菜单json字符串
$jsonMenu = '
{
"button": [
{
"name": "资源管理",
"sub_button": [
{
"type": "view",
"name": "我的记录",
"url": "http://m.test.net/h5/my/index",
"sub_button": [ ]
},
{
"type": "click",
"name": "使用说明1",
"key": "SYSM-001",
"sub_button": [ ]
},
{
"type": "click",
"name": "使用说明2",
"key": "SYSM-002",
"sub_button": [ ]
}
]
},
{
"name": "加盟培训",
"sub_button": [
{
"type": "view",
"name": "安全通告",
"url": "http://mp.weixin.qq.com/s/haHruj5RgoawpYOoEUA1CA",
"sub_button": [ ]
},
{
"type": "view_limited",
"name": "图文消息1",
"media_id": "O4NvReZyZPUCT4efE3q6FwtfaTmWyEgIbLg2arIGiA0"
},
{
"type": "view_limited",
"name": "图文消息2",
"media_id": "O4NvReZyZPUCTyefE3q6FwlTyoldJsDiHbFKCwdmPSc"
},
]
},
]
}';
文本回复的菜单需在代码中作相应处理,检测event中click,匹配key值,回复对应文本消息内容
public function weixin(){
$postStr = $this->input->raw_input_stream;
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
if(!empty($postObj)){
$MsgType = $postObj->MsgType;
switch($MsgType){
case "text":
$resultStr = $this->_handle_text($postObj);
break;
case "event":
$resultStr = $this->_handle_event($postObj);
break;
default:
$resultStr = "Unknow msg type: ".$MsgType;
break;
}
echo $resultStr;
}
else{
echo 'error';
}
}
function _handle_event($postObj){
$openid = strval($postObj->FromUserName);
$EventKey = strval($postObj->EventKey);
ll('Weixinlib');
$userinfo = $this->weixinlib->get_user_info($openid); // 获取平台用户信息 array
$msgType = 'text';
switch (strtolower($postObj->Event))
{
case "subscribe":
$content = $this->_handle_event_subscribe($postObj,$userinfo);
break;
case "scan":
$content = $this->_handle_event_scan($postObj,$userinfo);
break;
case "click"://文本消息回复处理
$content = $this->_handle_event_click($postObj);
break;
default :
$content = "Unknow Event: ".$postObj->Event;
break;
}
$resultStr = $this->_response($postObj, $content,$msgType);
return $resultStr;
}
function _handle_event_click($postObj){
$scene = $postObj->EventKey;
return $this->_click_handle_scene($scene);
}
function _click_handle_scene($scene){
switch ($scene){
case 'SYSM-001':
$resultStr = "SYSM-001对应的文本消息";
break;
case 'SYSM-002':
$resultStr = "SYSM-001对应的文本消息";
break;
default:
$resultStr = "unknow click";
break;
}
return $resultStr;
}
function _response($object, $content,$msgType = 'text'){
if(empty($content)){
return;
}
if($msgType == 'text'){
return $this->_response_text($object, $content);
}else if($msgType == 'news'){ //图文消息
return $this->_response_news($object, $content);
}
}
private function _response_text($object, $content, $flag=0)
{
$textTpl = "
%s
%d
";
$resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $flag);
return $resultStr;
}
调用创建菜单接口,创建菜单
$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=$access_token";
$output = http_post($url, $jsonMenu);
成功返回:{"errcode":0,"errmsg":"ok"}
