App端登陸相關的SDK需要在manifest中配置:
打開 manifest.json -> App模塊權限配置,勾選 OAuth(登陸鑑權)。
打開 manifest.json -> App SDK配置,查看到登陸鑑權。在說明中有藍色鏈接,其中包括向微信、QQ、微博等平臺申請sdk的鏈接。
向微信、QQ、微博等平臺申請到sdk的信息後,回填到manifest裏。
這些配置需要打包生效,真機運行仍然是HBuilder基座的設置,可使用自定義基座包。離線打包請參考離線打包文檔在原生工程中配置。
配置並打包後,通過uni.getProvider可以得到配置的結果列表,注意這裏返回的是manifest配置的,與手機端是否安裝微信、QQ、微博無關。
如果手機端未安裝QQ、微博,調用時會啓動這些平臺的wap頁面登陸,如果已安裝相應客戶端,會啓動它們的客戶端登陸。
APP微信授權登錄
uni.login({
provider: 'weixin',
success: res => {
uni.getUserInfo({
provider: 'weixin',
success: function(infoRes) {
let formdata = {
nickName: infoRes.userInfo.nickName,
gender: infoRes.userInfo.gender,
headImgUrl: infoRes.userInfo.avatarUrl,
openId: infoRes.userInfo.openId,
unionId: infoRes.userInfo.unionId
};
uni.request({
url: 'http://192.168.43.205:8080/thirdPartLogin/app/login',
method: 'POST',
data: formdata,
header: {
'content-type': 'application/x-www-form-urlencoded'
},
success: res => {
if (res.data.code != 200) {
uni.showToast({
title: res.data.err,
duration: 3000,
icon: 'none'
});
return false;
} else {
//登錄成功處理
uni.showToast({
title: res.data.message,
duration: 3000,
icon: 'none'
});
let ticket = res.data.ticket;
uni.setStorageSync('ticket', ticket);
uni.reLaunch({
url: '../my/my'
});
return true;
}
}
});
}
});
},
fail: err => {
uni.showToast({
title: '請求出錯啦!',
icon: 'none',
duration: 3000
});
}
});
後端直接根據unionId來判斷用戶的唯一性。
APPQQ授權登錄
uni.login({
provider: 'qq',
success: resp => {
var access_token = resp.authResult.access_token;
uni.getUserInfo({
provider: 'qq',
success: function(infoRes) {
var formdata = {
nickName: infoRes.userInfo.nickname,
gender: infoRes.userInfo.gender == '男' ? 1 : 2,
headImgUrl: infoRes.userInfo.figureurl_qq_2,
openId: infoRes.userInfo.openId,
access_token: access_token
};
uni.request({
url: 'http://192.168.43.205:8080/thirdPartLogin/app/login',
method: 'POST',
data: formdata,
header: {
'content-type': 'application/x-www-form-urlencoded'
},
success: res => {
if (res.data.code != 200) {
uni.showToast({
title: res.data.err,
duration: 3000,
icon: 'none'
});
return false;
} else {
//登錄成功處理
uni.showToast({
title: res.data.message,
duration: 3000,
icon: 'none'
});
let ticket = res.data.ticket;
uni.setStorageSync('ticket', ticket);
uni.reLaunch({
url: '../my/my'
});
return true;
}
}
});
}
});
},
fail: err => {
uni.showToast({
title: '請求出錯啦!',
icon: 'none',
duration: 3000
});
}
});
後端直接根據access_token來判斷用戶的唯一性。
以上展示的都是最重要的代碼,複製就可以使用,自己可以加一些加載顯示等。
