浪琴湾好玩吗,门头沟王洪钟被双开,创意标牌
前言
公司做海外产品的，集成的是 google 账号登录，账号信息、邮箱等这些不涉及隐私的按 google 的正常登录流程可以轻松实现 。但是一旦需要获取涉及隐私的信息就比较麻烦，文档也不是十分清晰，非常难找，很多坑。
google 账号登录
官方链接：https://developers.google.com/identity/sign-in/android/start
https://developers.google.com/identity/sign-in/android/sign-in
google 账号登录接入的坑：
我要评论client_id必须是 api console 后台 ：https://console.cloud.google.com/apis 与 google play 后台对应的应用关联起来。client_id 下的签名信息和报名信息必须和测试时的 apk 的签名信息和报名信息一致。google 登录的流程在这个文档写的比较清楚了：https://developers.google.com/identity/sign-in/android/sign-in，这里大致说一下，不贴代码了
构建需求请求的内容：
googlesigninoptions gso = new googlesigninoptions.builder(googlesigninoptions.default_sign_in)
.requestemail()
.requestidtoken("your client_id")
.build();
// build a googlesigninclient with the options specified by gso.
mgooglesigninclient = googlesignin.getclient(this, gso);
2.发起登录请求，跳转 google 登录页面。
intent signinintent = mgooglesigninclient.getsigninintent(); startactivityforresult(signinintent, rc_sign_in);
获取 google 登录返回
@override
public void onactivityresult(int requestcode, int resultcode, intent data) {
super.onactivityresult(requestcode, resultcode, data);
// result returned from launching the intent from googlesigninclient.getsigninintent(...);
if (requestcode == rc_sign_in) {
// the task returned from this call is always completed, no need to attach
// a listener.
task<googlesigninaccount> task = googlesignin.getsignedinaccountfromintent(data);
handlesigninresult(task);
}
}
获取 用户 id token,传到你自己的 服务端 做验证
private void handlesigninresult(task<googlesigninaccount> completedtask) {
try {
googlesigninaccount account = completedtask.getresult(apiexception.class);
// signed in successfully, show authenticated ui.
} catch (apiexception e) {
// the apiexception status code indicates the detailed failure reason.
// please refer to the googlesigninstatuscodes class reference for more information.
log.w(tag, "signinresult:failed code=" + e.getstatuscode());
}
}
切换账号
/**
* 重新获取账号列表
*/
public void revokeaccess() {
try {
if (mgooglesigninclient!=null && mactivity!=null){
mgooglesigninclient.revokeaccess().addoncompletelistener(mactivity, new oncompletelistener<void>() {
@override
public void oncomplete(@nonnull task<void> task) {
log.d(tag, "oncomplete: ");
}
});
}
} catch (exception e){
e.printstacktrace();
}
}
获取公开资料和需要特别授权的信息（性别、生日等）
1、在构建请求是新增获取 的公共资料信息 及 需要获取的特殊信息
private static final string gender_scope = "https://www.googleapis.com/auth/user.gender.read";
googlesigninoptions gso = new googlesigninoptions.builder(googlesigninoptions.default_sign_in)
.requestemail()
.requestidtoken("your client_id")
.requestscopes(new scope(gender_scope));
.build();
// build a googlesigninclient with the options specified by gso.
mgooglesigninclient = googlesignin.getclient(this, gso);
需要请求的信息可在如下链接查找：
2、检测是否有权限
googlesigninaccount lastsignedinaccount = googlesignin.getlastsignedinaccount(mactivity);
scope scope = new scope(gender_scope);
if (utils.isneedrequest() && !googlesignin.haspermissions(lastsignedinaccount,scope)){
sglog.d(tag+" need requst permission...");
googlesignin.requestpermissions(mactivity,rc_get_token,lastsignedinaccount,scope);
}
注意：这一步不需要也可以，有这一步会出现一个 “再确认” 的授权页面，没有也不影响获取的信息。
3、跳转登录页面 （同以上 google 账号登录）
4、获取登录信息 （同以上 google账号登录）
5、开启线程获取 特殊信息
getprofileasynctask = new getprofileasynctask(mactivity, new gpprofileinfocallback() {
@override
public void ongetprofileinfo(person person) {
sglog.d(tag+" ongetprofileinfo... ");
getprofileinfo(person);
}
});
getprofileasynctask.execute(signinaccount);
异步任务
// global instance of the http transport
private static final httptransport http_transport = androidhttp.newcompatibletransport();
// global instance of the json factory
private static final jsonfactory json_factory = jacksonfactory.getdefaultinstance();
private static class getprofileasynctask extends asynctask<googlesigninaccount, void, person> {
// retrieved from the sigin result of an authorized googlesignin
private weakreference<activity> mactivityref;
private gpprofileinfocallback mprofileinfocallback;
public getprofileasynctask(activity activity,gpprofileinfocallback callback) {
mactivityref = new weakreference<>(activity);
mprofileinfocallback = callback;
}
@override
protected person doinbackground(googlesigninaccount... params) {
if (mactivityref.get() == null){
sglog.d(tag+" getprofileasynctask doinbackground activity is null.");
return null;
}
googlesigninaccount signinaccount = params[0];
context context = mactivityref.get().getapplicationcontext();
googleaccountcredential credential = googleaccountcredential.usingoauth2(
context,
collections.singleton(gender_scope));
credential.setselectedaccount(signinaccount.getaccount());
sglog.d(tag+" get profile info start.");
peopleservice service =
new peopleservice.builder(http_transport, json_factory, credential)
.setapplicationname(apkutils.getappname(context)) // your app name
.build();
sglog.d(tag+" get profile info start.");
// get info. on user
person person =null;
try {
person = service
.people()
.get("people/me")
.setpersonfields("genders")
.execute();
sglog.d(tag+" getperson end.");
// return the result
if (mprofileinfocallback!=null){
mprofileinfocallback.ongetprofileinfo(person);
}
} catch (exception e) {
sglog.e(tag+e.getmessage());
if (mprofileinfocallback!=null){
mprofileinfocallback.ongetprofileinfo(null);
}
e.printstacktrace();
}
return person;
}
@override
protected void onpostexecute(person avoid) {
super.onpostexecute(avoid);
}
}
获取性别信息
private void getprofileinfo(person person){
sglog.d(tag+" executeprofileinfo...");
if (person == null){
notifyresult(mlastuser,utils.success);
}else {
try {
list<gender> genders = person.getgenders();
gender gender = genders.get(0);
string value = gender.getvalue();
sglog.d(tag+" genders:"+genders.size()+ " gender:"+value);
mlastuser.setgender(value);
notifyresult(mlastuser,utils.success);
}catch (exception e){
sglog.e(tag+" getprofileinfo error.");
notifyresult(null,sgerrorcode.login_failed);
e.printstacktrace();
}
}
}
