我的小程序测试腾讯AI服务--人脸验证，我在云平台下测试没有问题， [图片] 我下PHP的接口文件（tencentcloud-sdk-php-master），放在自己的服务器根目录，代码一样，测试通不过。 <?php require_once '/TCloudAutoLoader.php';   //这里就通不过，提示HTTP 500错误  为什么？？？？？？？ echo 'test'; /** use TencentCloud\Common\Credential; use TencentCloud\Common\Profile\ClientProfile; use TencentCloud\Common\Profile\HttpProfile; use TencentCloud\Common\Exception\TencentCloudSDKException; use TencentCloud\Iai\V20180301\IaiClient; use TencentCloud\Iai\V20180301\Models\VerifyFaceRequest; echo 'test';  * try {  *     $cred = new Credential("Axxxxxxvxsdgsdgsdc4", "jxxxxxxxxxxxxxxxxxxxxxxxxxnh");  *     $httpProfile = new HttpProfile();  *     $httpProfile->setEndpoint("iai.tencentcloudapi.com");  *         *     $clientProfile = new ClientProfile();  *     $clientProfile->setHttpProfile($httpProfile);  *     $client = new IaiClient($cred, "ap-chengdu", $clientProfile);  *     $req = new VerifyFaceRequest();  *       *     $params = '{"Url":"http://118xxxxxxxxxxxxx052.jpg","PersonId":"136xxxxxx52"}';  *     $req->fromJsonString($params);  *     $resp = $client->VerifyFace($req);  *     print_r($resp->toJsonString());  * }  * catch(TencentCloudSDKException $e) {  *     echo $e;  * }  */

安卓系统，为什么要启用手机位置信息才能用？？？为什么要重新开启程序signalStrength才能有新的变化？？？？？？ getConnectedWifi:function(){ var that = this that.stopWifi(); that.startWifi(); wx.getConnectedWifi({ success: function(res){ console.log(res); that.setData({ message2: res.wifi.SSID}); that.setData({ message3: res.wifi.signalStrength}); }, fail:function(err){ console.log(err); that.setData({ message2: err.errCode});  //'失败''失败' } }) },

安卓系统，代码如下 ，当前连接，距WIFI点远近，手机显示强弱环境，getConnectedWifi返回的wifi.signalStrength都为99是怎么回事? getConnectedWifi:function(){ var that = this that.stopWifi(); that.startWifi(); wx.getConnectedWifi({ success: function(res){ console.log(res); that.setData({ message2: res.wifi.SSID}); that.setData({ message3: res.wifi.signalStrength}); }, fail:function(err){ console.log(err); that.setData({ message2: err.errCode});  //'失败''失败' } }) },
