前端框架:uniapp,後端:java

1.後端代碼(獲取前端配置微信需要的數據,主要是簽名必須在後端生成)

a.獲取accesstoken

    private static String accessToken="";
    private static long lastAccessTokenTime=0;

    //獲取全局的accessToken
    public static synchronized String getPublicAccessToken(){
    long now= Calendar.getInstance().getTimeInMillis();
        if((now-lastAccessTokenTime)>(3000000)){//當大於3000秒的時候再去獲取新的
            String url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="+wx_public_appId+"&secret="+wx_public_secret;
            String response=HttpUtil.sendPost(url);//執行http請求
            JSONObject jsonObject=JSON.parseObject(response);

            if(jsonObject!=null&&!jsonObject.containsKey("errcode")){//請求成功,返回access_token
                accessToken=jsonObject.getString("access_token");
                lastAccessTokenTime=now;
                return accessToken;
            }
            return null;
        }else{
            return accessToken;
        }
    }

b.獲取

    private static String jsapi_ticket="";
    private static long lastJsApiTicketTime=0;

    //獲取全局的jsapi_ticket
    public static String getPublicJsApiTicket(){
        long now= Calendar.getInstance().getTimeInMillis();
        String tempAccessToken=getPublicAccessToken();
        if(tempAccessToken==null){
            return null;
        }
        if((now-lastJsApiTicketTime)>(3000000)){//當大於3000秒的時候再去獲取
            String url="https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token="+tempAccessToken+"&type=jsapi";
            String response=HttpUtil.sendPost(url);//請求http
            JSONObject jsonObject=JSON.parseObject(response);

            if(jsonObject!=null&&jsonObject.containsKey("ticket")){//請求成功
                jsapi_ticket=jsonObject.getString("ticket");
                lastJsApiTicketTime=now;
                return jsapi_ticket;
            }

            return null;
        }else{
            return jsapi_ticket;
        }
    }

c.獲取簽名的配置參數，返回給前端

        long timestamp=Calendar.getInstance().getTimeInMillis()/1000;
        String appId=Configs.wx_public_appId;//微信公衆號的appId
        String nonceStr="nonceStr"+((int)(Math.random()*100000));
        String ticket=getPublicJsApiTicket();//獲取ticket
        System.out.println("jsapiTicket:"+ticket);

        String tempSign="jsapi_ticket="+ticket+"&noncestr="+nonceStr+"&timestamp="+timestamp+"&url="+url;
        System.out.println("tempSign:"+tempSign);

        String signature= MD5Utils.getSha1(tempSign);//執行md5加密,進行簽名

        Map<String,Object> map=new HashMap<>();
        map.put("appId",appId);
        map.put("timestamp",timestamp);
        map.put("nonceStr",nonceStr);
        map.put("signature",signature);
        return map;

2.前端代碼

前端直接調用如下代碼，便可以完成配置

nowUrl爲當前前端頁面的url，微信需要用此來驗證是否有權限配置獲取方式:

var nowUrl=window.location.href.split("#")[0];//本網頁的鏈接，配置分享頁需要使用!


var wx = require('@/tools/wechat.js')

export function setShareInfo(nowUrl,shareInfo){
	queryJsApiConfig({//執行http請求，去後臺獲取配置信息
		url:nowUrl
	},function(data){
		wx.config({
			debug:false,
			appId:data.appId,
			timestamp:data.timestamp,
			nonceStr:data.nonceStr,
			signature:data.signature,
			jsApiList:['updateAppMessageShareData','updateTimelineShareData']
		});
		wx.ready(function(){
			wx.updateAppMessageShareData({
			  title: shareInfo.title, // 分享標題
			  desc: shareInfo.desc, // 分享描述
			  link: shareInfo.link, // 分享鏈接，該鏈接域名或路徑必須與當前頁面對應的公衆號JS安全域名一致
			  imgUrl: shareInfo.imgUrl, // 分享圖標
			  success: function () {}
			});
			wx.updateTimelineShareData({
			  title: shareInfo.title, // 分享標題
			  desc: shareInfo.desc, // 分享描述
			  link: shareInfo.link, // 分享鏈接，該鏈接域名或路徑必須與當前頁面對應的公衆號JS安全域名一致
			  imgUrl: shareInfo.imgUrl, // 分享圖標
			  success: function () {}
			})
		});
	});
}

wechat.js:

微信提供的js，可以自行去官網下載，也可以直接複製下面的代碼即可！

基本便是這樣，第一次配置的時候會各種錯很麻煩，而且配置必須在生產環境纔可以，或者需要去微信公衆號配置域名

公衆號需配置的地方如下圖:

1.配置白名單，只有配置了白名單的ip才能獲取到accesstoken。

2.配置js接口安全域名，前端獲取的nowurl必須配置在這裏，這裏必須是備案的域名，否則不能配置成功。

3.網頁授權域名，這個是微信公衆號登錄的話必須要配置！
