本篇文档介绍在 Wilddog Auth 中如何使用新浪微博对用户进行身份认证。

前期准备

在控制面板中创建应用。请参考控制面板-创建应用。
在新浪微博开放平台管理中心，获取应用的 App Key 和 App Secret。
在控制面板身份认证—登录方式中打开微博登录方式，配置 App Key 和 App Secret。

实现微博认证

1.安装 Wilddog Auth SDK：

将以下 pod 包含在你的 Podfile 中：

  pod 'Wilddog/Auth'

安装 SDK：

  $ pod install

2.创建 Wilddog Auth 实例：

Objective-C Swift

objectivec
WDGOptions *option = [[WDGOptions alloc] initWithSyncURL:@"https://<your-wilddog-appid>.wilddogio.com"];
[WDGApp configureWithOptions:option];

swift
let options = WDGOptions.init(syncURL: "https://<your-wilddog-appid>.wilddogio.com")
WDGApp.configure(with: options)

3.参考新浪微博 iOS 接入指南将新浪微博登录集成到你的应用中。在 AppDelegate 的 application: openURL: options: 方法中设置 delegate 来接收网络事件:

Objective-C Swift

objectivec
 - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
 {
     if([url.absoluteString hasPrefix:@"wb"]) {
        return [WeiboSDK handleOpenURL:url delegate:self];
     }
     return NO;
 }

swift
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if url.absoluteString.hasPrefix("wb") {
        return WeiboSDK.handleOpenURL(url, delegate: self)
    }
}

调用新浪微博的授权代码：

Objective-C Swift

objectivec
 WBAuthorizeRequest *request = [WBAuthorizeRequest request];
 request.redirectURI = @"https://api.weibo.com/oauth2/default.html";
 request.scope = @"all";
 request.userInfo = @{@"SSO_From": @"SendMessageToWeiboViewController",
                      @"Other_Info_1": [NSNumber numberWithInt:123],
                      @"Other_Info_2": @[@"obj1", @"obj2"],
                      @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};

 [WeiboSDK sendRequest:request];

swift
let request = WBAuthorizeRequest.request() as! WBAuthorizeRequest
request.redirectURI = "https://api.weibo.com/oauth2/default.html"
request.scope = "all"
request.userInfo = ["SSO_From": "SendMessageToWeiboViewController",
                    "Other_Info_1": NSNumber(int: Int32(123)),
                    "Other_Info_2": ["obj1", "obj2"],
                    "Other_Info_3": ["key1": "obj1", "key2": "obj2"]]
WeiboSDK.sendRequest(request)

在你的 delegate 中，实现 didReceiveWeiboResponse: 方法，并从中获取用户登录的 accessToken 和 userID：

Objective-C Swift

objectivec
 - (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
    if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
        WBAuthorizeResponse *authResponse = (WBAuthorizeResponse *)response;
        NSString *accessToken = authResponse.accessToken;
        NSString *openId = authResponse.userID;
    }
}

swift
func didReceiveWeiboResponse(response: WBBaseResponse!){
    if response is WBAuthorizeResponse{
        let authResponse = response as! WBAuthorizeResponse
        let accessToken = authResponse.accessToken
        let openId = authResponse.userID
    }
}

4.新浪微博登录成功后，在 didReceiveWeiboResponse: 方法中得到的 accessToken 和 userID 生成 credential：

Objective-C Swift

objectivec
WDGAuthCredential *credential = 
[WDGSinaAuthProvider credentialWithAccessToken:sinaOAuth.accessToken userID:userID];

swift
let credential = WDGSinaAuthProvider.credential(withAccessToken: sinaOAuth.accessToken, userID: sinaOAuth?.userID)

5.使用 credential 进行 Auth 用户认证：

Objective-C Swift

objectivec
[[WDGAuth auth] signInWithCredential:credential
                completion:^(WDGUser *user, NSError *error) {
                            // ...
                          }];

swift
WDGAuth.auth()?.signIn(with: credential){(user, error) in
    // ...
}

退出登录

signOut: 方法用于用户退出登录：

Objective-C Swift

objectivec
NSError *error;
[[WDGAuth auth] signOut:&error];
if (!error) {
    // 退出登录成功
}

swift
try! WDGAuth.auth()!.signOut()
