第一步：用戶同意授權(quán)，獲取code
讓客戶滿意是我們工作的目標(biāo)，不斷超越客戶的期望值來自于我們對這個行業(yè)的熱愛。我們立志把好的技術(shù)通過有效、簡單的方式提供給客戶，將通過不懈努力成為客戶在信息化領(lǐng)域值得信任、有價值的長期合作伙伴，公司提供的服務(wù)項目有：域名申請、網(wǎng)絡(luò)空間、營銷軟件、網(wǎng)站建設(shè)、合浦網(wǎng)站維護(hù)、網(wǎng)站推廣。
在確保微信公眾賬號擁有授權(quán)作用域（scope參數(shù)）的權(quán)限的前提下（服務(wù)號獲得高級接口后，默認(rèn)帶有scope參數(shù)中的snsapi_base和snsapi_userinfo），引導(dǎo)關(guān)注者打開如下頁面：
https://open.weixin.qq.com/connect/oauth3/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect
所以
先用調(diào)試接口生成自定義菜單，菜單json如下：
{
"button":[
{
"name":"風(fēng)信科技",
"sub_button":[
{
"type":"click",
"name":"關(guān)于風(fēng)信",
"key":"FS_V1_1001"
},
{
"type":"click",
"name":"我們的服務(wù)",
"key":"FS_V1_1002"
},
{
"type":"click",
"name":"成功案例",
"key":"FS_V1_1003"
},
{
"type":"click",
"name":"解決方案",
"key":"FS_V1_1004"
},
{
"type":"click",
"name":"OA通訊錄",
"key":"FS_V1_1005"
}]
},
{
"name":"風(fēng)信產(chǎn)品",
"sub_button":[
{
"type":"click",
"name":"平臺產(chǎn)品",
"key":"FS_V2_1001"
},
{
"type":"click",
"name":"領(lǐng)域產(chǎn)品",
"key":"FS_V2_1002"
},
{
"type":"click",
"name":"行業(yè)產(chǎn)品",
"key":"FS_V2_1003"
},
{
"type":"view",
"name":"微辦公",
"url":"https://open.weixin.qq.com/connect/oauth3/authorize?appid=$APPID&redirect_uri=$URL&response_type=code&scope=snsapi_base&state=1#wechat_redirect"
}]
},
{
"name":"風(fēng)信娛樂",
"sub_button":[
{
"type":"click",
"name":"抽獎活動",
"key":"FS_V3_1001"
},
{
"type":"click",
"name":"查詢天氣",
"key":"FS_V3_1002"
},
{
"type":"view",
"name":"更多活動",
"url":"http://www.funsing.com/"
}]
}]
}
第二步，獲取openId,
public function index() {
$code = I('get.code');
$weid = $this->getOpenId($code);
if ($weid == "") {
$this->redirect('/Home/Index/login', array(), 0, "waiting...");
} else {
$result = json_decode($this->client->IsAccount(array("weId"=>$weid))->IsAccountResult);
$info = $result->ErrMsg;
$this->gotoPage($info, $weid);
}
}//通過code取得openid
public function getOpenId($code) {
$urlpre = "https://api.weixin.qq.com/sns/oauth3/access_token?appid=".$this->appId."&secret=".$this->appsecret."&grant_type=authorization_code&code=";
$url = $urlpre.$code;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
$jsoninfo = json_decode($output, true);
//$access_token = $jsoninfo["access_token"];
$openid = $jsoninfo["openid"];
return $openid;
}
