項(xiàng)目中用到微信第三方登錄牍颈，吐槽下微信登錄demo，基本是沒看琅关。煮岁。。主要參照微信第三方登錄文檔涣易，不得不說文檔確實(shí)比demo好很多
1画机、在微信開放平臺(tái)申請(qǐng)賬號(hào)，注冊應(yīng)用新症，拿到appId和appSecret步氏，后臺(tái)部分搞定；
2账劲、下載微信官方sdk，將需要的framework拖進(jìn)工程中金抡；
3瀑焦、設(shè)置微信白名單和URL type 這里就忽略掉了；
4梗肝、集成開發(fā)
首先榛瓮、在appdelegate里面注冊appId（只要打開應(yīng)用就會(huì)走的這個(gè)方法）
-(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[WXApi registerApp:WX_App_ID withDescription:@""];
return YES;
}
其次，在登錄頁面調(diào)起微信app
-(void)weChatLogin {
if ([WXApi isWXAppInstalled]) {
SendAuthReq *req = [[SendAuthReq alloc] init];
//這里是按照官方文檔的說明來的此處我要獲取的是個(gè)人信息內(nèi)容
req.scope = @"snsapi_userinfo";
req.state = @"";
//向微信終端發(fā)起SendAuthReq消息
[WXApi sendReq:req];
} else {
DPFLog(@"安裝微信客戶端");
}
}
接下來巫击，我們在微信里面為我們的app授權(quán)禀晓，此處微信里面操作精续； 授權(quán)完成之后回到我們app，微信的回應(yīng)
// WXApiDelegate
-(void)onResp:(BaseResp *)resp{
if ([resp isKindOfClass:[SendAuthResp class]]) {
SendAuthResp *temp = (SendAuthResp *)resp;
if (temp.code != NULL) {
//此處判斷下返回來的code值是否為錯(cuò)誤碼 /*此處接口地址為微信官方提供粹懒，我們只需要將返回來的code值傳入再配合appId和appSecret即可獲取到accessToken重付，openId和refreshToken */
NSString *accessUrlStr = [NSString stringWithFormat:@"%@/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code", WX_BASE_URL, WX_App_ID, WX_App_Secret, temp.code];
[GameRequestTool getWithUrlString:accessUrlStr success:^(id data) {
NSDictionary *dict = [data objectFromJSONData];
NSString *accessToken = [dict objectForKey:WX_ACCESS_TOKEN]; NSString *openID = [dict objectForKey:WX_OPEN_ID];
NSString *refreshToken = [dict objectForKey:WX_REFRESH_TOKEN]; // 本地持久化，以便access_token的使用凫乖、刷新或者持續(xù)
if (accessToken && ![accessToken isEqualToString:@""] && openID && ![openID isEqualToString:@""]) {
[[NSUserDefaults standardUserDefaults] setObject:accessToken forKey:WX_ACCESS_TOKEN];
[[NSUserDefaults standardUserDefaults] setObject:openID forKey:WX_OPEN_ID];
[[NSUserDefaults standardUserDefaults] setObject:refreshToken forKey:WX_REFRESH_TOKEN];
[[NSUserDefaults standardUserDefaults] synchronize];
// 命令直接同步到文件里确垫，來避免數(shù)據(jù)的丟失
}
//請(qǐng)求個(gè)人信息
[self requestUserInfoDescription];
} failure:^(NSError *error) {
DPFLog(@"error -- %@", error);
} showView:self.window];
} else {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"獲取微信授權(quán)失敗" preferredStyle:(UIAlertControllerStyleAlert)];
[alertController addAction:[UIAlertAction actionWithTitle:@"確認(rèn)" style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
}]];
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alertController animated:YES completion:nil];
}
}
}
最后我們獲取授權(quán)用戶的詳細(xì)信息
-(void)requestUserInfoDescription {
//獲取當(dāng)上一步保存的accessToken 和 openId
NSString *accessToken = [[NSUserDefaults standardUserDefaults] objectForKey:WX_ACCESS_TOKEN];
NSString *openID = [[NSUserDefaults standardUserDefaults] objectForKey:WX_OPEN_ID];
//使用微信官方提供的接口獲取授權(quán)用戶個(gè)人信息
NSString *userUrlStr = [NSString stringWithFormat:@"%@/userinfo?access_token=%@&openid=%@", WX_BASE_URL, accessToken, openID];
[GameRequestTool getWithUrlString:userUrlStr success:^(id data) { NSDictionary *dict = [data objectFromJSONData];
DPFLog(@"dict -- %@", dict);
NSString *nickname = [dict objectForKey:@"nickname"];
if (nickname != NULL) {
LogInViewController *loginVC = [[LogInViewController alloc]init];
[self.window addSubview:loginVC.view];
} else {
DPFLog(@"登錄失敗、帽芽、删掀、");
}
} failure:^(NSError *error) {
DPFLog(@"error -- %@", error);} showView:self.window];
}
以上就是iOS微信第三方登錄，并且獲取授權(quán)用戶個(gè)人信息的過程导街，其實(shí)這里有個(gè)問題披泪，我們需要將請(qǐng)求到的accessToken值放在服務(wù)器而不是放在客戶端，然而搬瑰，時(shí)間緊迫款票，最后也只能先放在客戶端。跌捆。徽职。
