- 当前 Bug 的表现(可附上截图)
无法获得openid
- 预期表现
可以获得openid
- 复现路径
每次都不行
- 提供一个最简复现 Demo
wx.login({
success: ret => {
// 发送 res.code 到后台换取 openId, sessionKey, unionId
var $post = {
code: ret.code
}
console.log("ret.code:" + ret.code)
console.log("JSON_stringify:" + JSON.stringify($post))
wx.request({
url: 'https://aptcollege.cn/tp5/index.php/index/index/wx_req2',
data: { js_code: JSON.stringify($post) },
//data: { js_code: ret.code },
method: 'POST',
header: {
'content-type': 'application/x-www-form-urlencoded'
},
success: function (res) {
wx.setStorageSync('third_session', res.data);
console.log(res)
},
fail: function (err) {
console.log(err)
}
})
后台
public function wx_req2()
{
header('Content-type:application/json');
$js_code = json_decode($_POST);
return json($js_code);
$url='https://api.weixin.qq.com/sns/jscode2session?appid=wx565931e3e9fe2902&secret=beca69ba684c6db053c725c0719700f8&js_code='.$js_code.'&grant_type=authorization_code';
//echo "url=[".$url."]";
$wxRet = file_get_contents($url);
//echo $wxRet."";
$wxRet_Arr = json_decode($wxRet,true);
}
