IOS development: Sina Weibo oau22.

Note: You must obtain user identity authentication when calling open interfaces on Weibo, such as Weibo and followers. Currently, oauth2.0. To facilitate developers to develop and test their own applications.

Compared with OAuth2.0, OAuth2.0 is simpler and safer than 1.0. It is also the most important way to authenticate and authorize users in the future.

Step 1: Create an application

Below I take this company test account as an example, the creation of application steps can refer to Sina's official API address: http://open.weibo.com application creation can be used at the development stage, this example of application information such

Step 2: Obtain the token number

Load the link through webView. client_id is the app Key of the application, and redirect_uri is the company jump link. Here I use this company link as an example.

UIWebView * web=[[UIWebView alloc] init]; web.frame=self.view.bounds; NSString*str=@https://api.weibo.com/oauth2/authorize?client_id=3272733387&redirect_uri=http://www.21-sun.com; NSURL * url=[NSURL URLWithString:str]; NSURLRequest *request=[NSURLRequest requestWithURL:url]; [web loadRequest:request]; [self.view addSubview:web]; web.delegate=self;

The effect interface is as follows:

The returned link is followed by the parameter code. We need to use this code. We can use the webView proxy to intercept the returned link.

# Pragma mark-allow the proxy to load requests-(BOOL) webView :( UIWebView *) webView shouldStartLoadWithRequest :( NSURLRequest *) request navigationType :( UIWebViewNavigationType) navigationType {NSString * str = request. URL. absoluteString; if ([str containsString: @ http://www.21-sun.com /? Code =]) {NSInteger index = [str rangeOfString: @ =]. location; NSString * code = [str substringFromIndex: index + 1]; return NO;} return YES ;}

Request access_token, using the following link request

// Client_id true string the AppKey allocated when the application is applied.

// Client_secret true string the AppSecret allocated when the application is applied.

// Grant_type true string request type, fill in authorization_code

// Code true string the code value obtained above.

// Redirect_uri true string callback address, which must be consistent with the callback address in the registered application.

　　The Code is as follows:

-(Void) _ getToken :( NSString *) code {NSDictionary * dic =@{@ client_id: @ 3272733387, @ client_secret: @ cret, @ grant_type: @ authorization_code, @ code: data, @ redirect_uri: @ http://www.21-sun.com}; AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager manager]; manager. responseSerializer. acceptableContentTypes = [NSSet setWithObject: @ text/plain]; [manager POST: @ https://api.weibo.com/oauth2/access_token parameters: dic success: ^ (AFHTTPRequestOperation * operation, NSDictionary * responseObject) {NSString * token = responseObject [@ access_token];} failure: ^ (AFHTTPRequestOperation * operation, NSError * error) {NSLog (@ request failed) ;}];}

Now we can use the access_token code we get to do a lot of things.
