Note:

Step 2,

Register as a developer. After verifying the email address, you can create a mobile application,

Write downAPPKey and APPSecret,

In the advanced information of the application information, set the address of the authorization completed callback page.Redirect_URI

Because it is a mobile client, not a web application,

Therefore, when creating an application,Redirect_URIYou can write at will,

However, the same address must be used globally.Redirect_URI

Step 2,

Apply for unauthorized request_code,

The essence is comingWeibo login page, That is, _ webView's first loaded url

The address format is as follows:

Https://api.weibo.com/oauth2/authorize? Client_id = APPKEY & response_type = code & redirect_uri = https://api.weibo.com/oauth2/default.html

APPKEY is the unique application ID automatically generated by the system when an application is created.

Redirect_uri, which must be consistent with the one you entered when creating the application

Step 2,

After entering the account and password, click log on,

The page is automatically redirected to the authorization page,

If you click the authorization button, the page will be redirected to http: // redirectURL /? Codes = 888888888888,

The task is to intercept the code value (Different every time),

This code is actuallyAuthorized request_code,

However, it is only a man-in-the-middle and cannot be used to obtain user information.

The address format is as follows:

Https://api.weibo.com/oauth2/default.html? Code = fa4efb6311611f948423e69adeabec08

Step 2,

Use the code intercepted in step 1 to assemble the url again,

Initiate the last request (must be a POST request ),

In this case, the data returned by the server is a json data,

It contains three key-value pairs

{

"Access_token": "This is the real ACCESS_TOKEN ",

"Remind_in": "157679999 ",

"Expires_in": 157679999,

"Uid": "uid of the authorized user"

}

On Sina Weibo's open platform, how does one apply for the accesstoken and accesstokensecret that have been authenticated by oauth?

I don't know much about java, but in c #, I have been using oauth for authorization. I also have a question: Who can extract the birthday of members on Sina Weibo?

For android, How can I save the oauth authorization with the logged-on user after obtaining the access token?

1. During the first authorization, you can save the token and secret in the SharedPreferences or SQLite database. The next login check reads the check first.
2. Search for "ppy2790 blog" in Baidu, including Sina Weibo Android Development Project, source code, and OAuth certification.
