Jsapi-java initial access, letter jsapi-java access

[Public account for developers]

Contact should be earlier than most people,

I remember that it would open a number, and most people do not know anything,

The rapid development is really powerful.

Many secondary developers develop public accounts,

But all are stuck on the "authentication,

Individuals cannot authenticate.

[Send a link to a Friend]

I encountered another problem today. I want to create a custom link to send to my friends,

This simple feature took an afternoon and finally found that authentication was required for sharing,

If you do not have any problems, make a record to help those who have the same problems.

[Java code]

As for the api or something, it is difficult, but it is not very difficult. It directly encapsulates a part of the Code:

Package com. uikoo9.util. external; import java. util. arrays; import java. util. hashMap; import java. util. map; import java. util. UUID; import javax. servlet. http. httpServletRequest; import org. json. JSONObject; import com. uikoo9.util. core. data. QStringUtil; import com. uikoo9.util. core. file.

There are three main parts:

1. token Verification

2. cache accesstoken and jsticket

3. Get js Parameters

Corresponding configuration file:

# weixin propertiesweixin.debug=falseweixin.token=yweixin.appid=yweixin.appsecret=y

In addition, you must call QWeixinUtil. runWeixinThread () when starting the service ();

private void initWeixinInfo(BlogArticleModel blog){        String jsTicket = (String) QCacheUtil.getFromEHCache("weixinjsticket");        String url = "http://uikoo9.com/blog/detail/" + blog.getStr("blog_article_code");        Map<String, String> map = QWeixinUtil.getJsSignMap(jsTicket, url);        setAttr("wxdebug", QPropertiesUtil.get("weixin.debug"));        setAttr("wxappid", QPropertiesUtil.get("weixin.appid"));        setAttr("wxtime", map.get("timestamp"));        setAttr("wxrandom", map.get("nonceStr"));        setAttr("wxsign", map.get("signature"));        setAttr("wxtitle", blog.getStr("blog_article_title"));        setAttr("wxurl", map.get("url"));    }

Corresponding page code:

<Script type = "text/javascript" src = "http://res.wx.qq.com/open/js/jweixin-1.0.0.js"> </script> <script type = "text/javascript"> wx. config ({debug :$ {wxdebug}, appId: '$ {wxappid}', timestamp :$ {wxtime}, nonceStr: '$ {wxrandom}', signature: '$ {wxsign}', jsApiList: ['onmenushareappmessage']}); wx. ready (function () {wx. onMenuShareAppMessage ({title: '$ {wxtitle}', desc: '$ {wxtitle}', link: '$ {wxurl}', imgUrl: 'http: // uikoo9.qiniudn.com/@/img/logo.png'});/* trigger: function (res) {alert ('user click to send to friends');}, success: function () {alert (1) ;}, cancel: function () {alert (2) ;}, fail: function (res) {alert (JSON. stringify (res);} wx. error (function (res) {alert (JSON. stringify (res);}); */</script>

[Notes]

You can follow the above configuration. Pay attention to the following points:

1. Make good use of wx. error, which can be used for debugging errors.

2. Make good use of debug: true in wx. config, which is also debugging and does not feel useful.

[Cheating Certification]

Open wx. error. If at this time you see:

Congratulations, you have succeeded,

However, if you click to send a message to a friend that is still not customized, congratulations,

This problem will be entangled for a long time,

At last, I will tell you that you do not have the permission to share the authentication.

Individuals cannot be authenticated. register a company ~~
