Android Sina Weibo oauth2.0 certification and custom webview Certification

First of all, I had to say that I had made a hole mistake, but I cannot blame myself completely, because everyone knows that the jar package provided by Sina Weibo oauth2.0 is more than 2 MB, no one seems to want to use it, so that I can study the use of 1.0. After a long time, I finally realized that it is available. Sina, the newest of the abnormal saying, wants to stop calling the 1.0 interface, I have to change it. Think about it as well. People upgrade it to make it easy to use. Well, don't complain, because Sina oauth2.0 is much more convenient and easier to use than 1.0. Here I will briefly explain:

First of all, I don't like the jar package method provided by Sina, So I integrated their source code into my application, which looks intuitive. in fact, it is very easy to copy the com.weibo.net package to your own project, and fix the bug. I will not talk about it here. The following describes how to use it:

Code snippet:

Weibo = Weibo. getinstance (); Weibo. setupconsumerconfig (consumer_key, consumer_secret); Weibo. setredirecturl (mredirecturl); // authenticate Weibo. authorize (mainactivity. this, new myweibodialoglistener ());

Class myweibodialoglistener implements weibodialoglistener {@ overridepublic void oncomplete (bundle values) {/*** save token and expires_in */string token = values. getstring ("access_token"); // obtain access_tokeneditor = preferences. edit (); Editor. putstring ("token", token); Editor. commit (); toast. maketext (mainactivity. this, Token, 1000 ). show (); // string expires_in = values. getstring ("expires_in"); // accesstoken = new accesstoken (token, consumer_secret); // accesstoken. setexpiresin (expires_in); intent = new intent (); intent. setclass (mainactivity. this, mainactivity. class); startactivity (intent) ;}@ overridepublic void onweiboexception (weiboexception e) {}@ overridepublic void onerror (dialogerror e) {}@ overridepublic void oncancel (){}}

In the above Code, we only need to save the token and expires_in values in the interface (so that we do not need to authenticate oauth again in the future), but we can only save the token, the value of expires_in is just a form. If it expires, the token will be invalid. At this time, you should re-Authenticate and obtain the new token value. (This is what we say here, I have not investigated it. I have time to study it and draw a conclusion. don't mind)

Send call:

If (token = NULL | token. equals ("") {toast. maketext (mainactivity. this, "oauth authentication first", 1000 ). show ();} else {utility. setauthorization (New oauth2accesstokenheader (); // This step cannot be saved. accesstoken = new accesstoken (token, consumer_secret); Weibo. getinstance (). setaccesstoken (accesstoken); Update (Weibo. getinstance (), Weibo. getappkey (), edittext. gettext (). tostring (), "", "");/***** obtain the corresponding interface data * // try {// getpublictimeline (Weibo. getinstance (); //} catch (malformedurlexception e) {// todo auto-generated Catch Block // E. printstacktrace (); //} catch (ioexception e) {// todo auto-generated Catch Block // E. printstacktrace ();//}}

Official source code:

    private void authorize(Activity activity, String[] permissions, int activityCode,            final WeiboDialogListener listener) {        Utility.setAuthorization(new Oauth2AccessTokenHeader());        boolean singleSignOnStarted = false;        mAuthDialogListener = listener;        // Prefer single sign-on, where available.        if (activityCode >= 0) {            singleSignOnStarted = startSingleSignOn(activity, APP_KEY, permissions, activityCode);        }        // Otherwise fall back to traditional dialog.        if (!singleSignOnStarted) {            startDialogAuth(activity, permissions);        }    }

Utility. setauthorization (New oauth2accesstokenheader ());

This statement should be executed before you create an accesstoken. Remember this, and I am not at a high level.

In this way, we have published a microblog.

At last, we also need to note that there is a deficiency in using their dialog authentication directly in our applications.

In fact, there is nothing, that is, it is inconvenient to use, and it will cover this view if you don't move it. Because the official website provides a dialog, we cannot use it.

Android: windowsoftinputmode = "adjustpan | statealwaysvisible"

But we can implement it in the Code. Add the following to oncreate in com.weibo.net. weibodialog. Java:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

In this way, we will not cover my iew. The effect is as follows:

You see, this will not affect you. By the way, I have processed dialog myself. You can also process it according to your own perspective.

The above is a brief introduction here, because the self-feeling is not flexible, let's look at several application views:

It looks friendly, so you need to create your own webview activity.

Next I will introduce how to implement it:

Create mywebviewactivity. Java

D (TAG, "onpagefinished URL:" + URL); super. onpagefinished (view, URL); linearlayout. setvisibility (view. gone);} public void onreceivedsslerror (webview view, sslerrorhandler handler, sslerror error) {handler. proceed () ;}} private void handleredirecturl (webview view, string URL) {bundle values = utility. parseurl (URL); string error = values. getstring ("error"); string error_code = values. getstring ("error_code"); // If (error = NULL & error_code = NULL) {mlistener. oncomplete (values); // rejection failed, etc.} else if (error. equals ("access_denied") {mlistener. oncancel ();} else {// mlistener exception. onweiboexception (New weiboexception (error, integer. parseint (error_code); }}@ overridepublic void oncomplete (bundle values) {/*** Save the access_token */string token = values here. getstring ("access_token"); sharedpreferences preferences = getsharedpreferences (mainactivity. file, 0); Editor editor = preferences. edit (); Editor. putstring ("token", token); Editor. commit (); accesstoken = new accesstoken (token, Weibo. getappsecret (); Weibo. getinstance (). setaccesstoken (accesstoken); setresult (result_ OK); finish () ;}@ overridepublic void onweiboexception (weiboexception e) {e. printstacktrace () ;}@ overridepublic void onerror (dialogerror e) {e. printstacktrace () ;}@ overridepublic void oncancel () {finish ();}}

Most of the above Code is the code in copy weibodialog. Java, just a slight change.

There are two most important parts: first, how to get the URL to be loaded, that is, the display of the authentication interface, and second, how to get the access_token value. With this value, we can call the API.

It's hard to understand.

(I won't cover up the first one, but the last one is)

The above is just a prototype. You can adjust the application according to your own project type. Does this look much better than calling the android Sina jar package directly,

In addition, the implementation is also flexible, and Sina oauth2.0 is not bad.

Thanks for you! ! !
