Java uses Sina Weibo API to develop the basic method of microblogging application _java

Sina Weibo API is now used more widely, do a complete development process demo
1, the first step of registration, do not say more, registered account and become a developer account, this step will not be the case, please immediately smash the computer unplug the network cable home farming.
2, the second step to create the application, the developer account to create a good, open Sina Weibo development platform: http://open.weibo.com
Above menu bar Click Last Admin Center

If it is a Web application, choose to create the application of the Web site access, and then according to the requirements of Sina Weibo Balabalabala own to do
Application creation completed. Click on the application Jump page, click to view the application parameters, you can see the application of the relevant parameters, these parameters will be used in the fourth step.
3, the third step to download the SDK, back to the top of the menu bar, click on the document, and then click on the left menu bar SDK, select the Java SDK, and then Balabala download, this step of the operation of the problem also please go home farming.

The so-called SDK is not the SDK (personally think the name is a bit misleading), but a can run the project, download after the decompression, and import to eclipse, you can see two directory src and example
SRC is part of Sina Weibo
Example is an example, the interface of the demo
4, the fourth step configuration parameters, find the config.properties under the SRC directory
The first three parameters need to be configured as parameters in the application parameters mentioned in the second step
The back is all the default, no need to change.
The first three parameters are configured as follows
client_id for App Key
Client_sercret for App Secret
Redirect_uri for OAuth2.0-Authorized callback URLs apply Information > Advanced Information >oauth2.0 Authorization settings The following authorization callback page this is a URL you've filled out to point to yourself. Server of course we can use any URL in the development phase As long as we can understand the process of OAuth authorization. Here we enter a http://www.baidu.com Cancel authorization callback page also note that the string of URLs here must be consistent
5, the fifth step to obtain accesstoken, under normal circumstances Accesstoken acquisition is required to pass OAuth2.0 authentication, but in order to be simpler I first say a simple method. I'll talk about OAuth2.0 later.
or select the top menu bar document >API>API Test Tool
Select the application you created click to get Accesstoken the text box below is what we want Accesstoken

6, the sixth step first to do an interface instance
Go to the microblogging API to find an existing interface,
I've been randomly looking for a user-posted microblogging statuses/user_timeline for testing.

Click on this interface to view the details of this interface, you can see the interface of each incoming parameter and return parameters this needless to say.

Implement OAuth authorization without using any SDK and implement a simple release microblogging function:
Create a Java project, write the following code, which is clearly written in the process code, no longer explained here:

Note Modify the application ID, apply password, and callback page first to your own! Access Authorization page:
