js部分：

Page({

data: {

nickName: “QQ账号登录”,

avatarUrl:”./user-unlogin.png”,

},

onLoad: function () {

var that = this;

var nickName = that.data.nickName ;

var avatarUrl = that.data.avatarUrl;

var db=”no”;

wx.getUserInfo({

success: function (res) {

that.data.nickName = res.userInfo.nickName,

that.data.avatarUrl = res.userInfo.avatarUrl,

that.setData({

nickName: that.data.nickName,

avatarUrl: that.data.avatarUrl,

}),

that.setData({

db:”ok”// 设置变量db，只有成功获取用户信息后才写入数据库

})

if(db = “ok”) {

var name, url;

wx.request({

url: ‘https://…/getuserinfo.php’,//写自己的服务器

header: {

“Content-Type”: “application/x-www-form-urlencoded”

},

method: “POST”,

data: {

name: res.userInfo.nickName,

url: res.userInfo.avatarUrl,

},

success: function () {

console.log(“success”)

},

fail: function () {

console.log(“fail”)

}

})

}

},

fail: function (res) {

that.data.nickName = “未授权无法获取用户信息”,

that.setData({

nickName: that.data.nickName

})

}

})

},

onShow: function () {

}

})

服务器部分getuserinfo.php文件：

$name = $_POST[‘name’];

$url = $_POST[‘url’];

$servername = “localhost”;

$username = “root”;

$password = “”;//服务器中连接数据库的密码

$dbname = “mydb”;//使用的数据库名

// 创建连接

$conn = new mysqli($servername, $username, $password, $dbname);

// 检测连接

if ($conn->connect_error) {

die(“connect server fail: ” . $conn->connect_error);

}

$sql = “INSERT INTO userinfo

VALUES (‘$name’, ‘$url’)”;

if ($conn->query($sql) === TRUE) {

echo “insert success”;

} else {

echo “Error: ” . $sql . “
” . $conn->error;

}

$conn->close();
