微信分享（配置+開發）簡單流程【只要配置的參數沒問題，就easy】

首先網上查資料，沒有和配置結合，踩了坑（又不愛看官方文檔，文字太多一堆口水話）

。。。。。整理下自己完整的步驟

1、公衆號【基本配置】裏面的【服務器配置】（下面必須要空降方法，不然配置驗證通不過）

一、首先項目導入公衆號的jar包

<!-- 微信公衆號 -->
<dependency>
   <groupId>com.github.binarywang</groupId>
   <artifactId>weixin-java-mp</artifactId>
   <version>2.3.0</version>
</dependency>

二、服務中WeixinController提供如下方法（注意：weixinService需要繼承WxMpServiceImpl

public class WeixinService extends WxMpServiceImpl）

weixinService.checkSignature(timestamp, nonce, signature)方法是jar包自帶的方法

/**
     * 1、用於公衆號【服務器配置】驗證——然後纔有token（坑）
     * @param signature
     * @param timestamp
     * @param nonce
     * @param echostr
     * @return
     */
    @RequestMapping(value = "/wechat/check.do", method = RequestMethod.GET, produces = "text/plain;charset=utf-8")
    public
    String authGet(@RequestParam("signature") String signature,
                   @RequestParam("timestamp") String timestamp, @RequestParam("nonce") String nonce,
                   @RequestParam("echostr") String echostr) {
        logger.info("接收到來自微信服務器的認證消息：[{},{},{},{}]", signature, timestamp, nonce, echostr);
        if (weixinService.checkSignature(timestamp, nonce, signature)) {
            return echostr;
        }
        return "非法請求";
    }

2、配置公衆號的appId、secretKey等參數

wechat.AppID=wx28xxxcf239xx
wechat.AppSecret=938b579878798619542d6xxxxxf03000
wechat.ybyc.token=自定義的token，copy過來
wechat.ybyc.EncodingAESKey=隨機生成的AESKey

3、獲取微信JSAPI初始化所需信息

Controller代碼

    @RequestMapping(value = "/wechat/config.do", method = RequestMethod.GET, produces = "application/json;charset=UTF-8")
    public String getWXConfig(HttpServletRequest request) throws Exception {
        Map map = new HashMap<>();
        Map resultMap = new HashMap<>();        
        try {
            map.put("clientUrl", request.getParameter("clientUrl"));//當前頁面所在的瀏覽器URL全路徑,由於該支付爲jssdk支付，所以需要url地址.參與後臺sign簽名
            /** 獲取用戶的微信客戶端版本號，用於前端支付之前進行版本判斷，微信版本低於5.0無法使用微信支付 */
            /*String userAgent = request.getHeader("user-agent");
            if (StringUtils.isNotBlank(userAgent)){
                char agent = userAgent.charAt(userAgent.indexOf("MicroMessenger") + 15);
                map.put("agent", new String(new char[]{agent}));
            }*/
			resultMap = weixinService.getConfig(map);            
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e.getMessage(), e);
        }
        return new Gson().toJson(resultMap);
    }

service代碼

    /**
     * 獲取微信JSAPI初始化所需信息
     */
    public Map getConfig(Map requestMap) {
        String clientUrl = (String) requestMap.get("clientUrl");
        String jsapiTicket = "";
        try {
            jsapiTicket = this.getJsapiTicket();
        } catch (WxErrorException e) {
            e.printStackTrace();
        }
        String nonceStr = 生成一個UUID;
        String timeStamp = Long.toString(System.currentTimeMillis() / 1000);
        String string1 = "jsapi_ticket=" + jsapiTicket +
                "&noncestr=" + nonceStr +
                "×tamp=" + timeStamp +
                "&url=" + clientUrl;
        String signature = "";
        signature = SHA1.gen(string1);
        //logger.info("待簽名的字符串爲：{}, 簽名後: {}", string1, signature);
        Map<String, Object> reponseMap = new HashMap<>();
        reponseMap.put("appId", 注意自己公衆號的appId);
        reponseMap.put("timeStamp", timeStamp);
        reponseMap.put("nonceStr", nonceStr);
        reponseMap.put("signature", signature);
        reponseMap.put("agent", requestMap.get("agent"));
        //微信分享相關
        reponseMap.put("imgUrl", "https://www.baidu.com/img/bd_logo1.png");
        reponseMap.put("shareTitle", "來自……爸爸的測試");
        reponseMap.put("descContent", "第一次測試有點緊張，不要慌");
        reponseMap.put("lineLink", "http://www.xxx.com/jxq/index.html");
        return reponseMap;
    }

4、前端wechat.js工具封裝的分享

var timeStamp,nonceStr,appId,agent;

var imgUrl,lineLink,shareTitle,descContent;

var shareType,shareId;

$(function(){
    //當前完整路徑（請求後臺，獲取jssdk支付所需的參數，應該可以不要）
    var clientUrl = window.location.href.split('#')[0];
	
    $.ajax({
        type: 'get',
        url: 'http://www.ybycedu.com/core/wechat/config.do',
        dataType: 'json',
        data: {
            "clientUrl": clientUrl //當前頁面所在的瀏覽器URL全路徑,由於該支付爲jssdk支付，所以需要url地址.參與後臺sign簽名
        },
        cache: false,
        error: function () {
            alert("系統錯誤，請稍後重試");
            return false;
        },
        success: function (data) {
            timeStamp = data.obj.timeStamp;
            nonceStr = data.obj.nonceStr;
            appId = data.obj.appId;
            agent = data.obj.agent;
            imgUrl = data.obj.imgUrl;
            lineLink = data.obj.lineLink;
            shareTitle = data.obj.shareTitle;
            descContent = data.obj.descContent;
            //JSSDK支付所需的配置參數，首先會檢查signature是否合法。
            wx.config({
                debug: false, //開啓debug模式，測試的時候會有alert提示
                appId: appId, //公衆平臺中-開發者中心-appid
                timestamp: timeStamp, //時間戳
                nonceStr: nonceStr, //隨機字符串,不長於32位
                signature: data.obj.signature, //這裏的signature是後臺使用SHA1簽名算法得出，不是MD5，與下面的wx.chooseWXPay中的paySign不同，下面的paySign是後臺使用MD5加密得出
                jsApiList: [ //指定哪些JS接口有權限訪問
                    'chooseWXPay','onMenuShareTimeline','onMenuShareAppMessage','getLocation','startRecord','stopRecord','onVoiceRecordEnd','playVoice','pauseVoice','stopVoice','onVoicePlayEnd','uploadVoice','downloadVoice'
                ]
            });
            //上方的config檢測通過後，會執行ready方法
            wx.ready(function () {
                if (typeof WeixinJSBridge == "undefined"){
                    if( document.addEventListener ){
                        document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
                    }else if (document.attachEvent){
                        document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
                        document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
                    }
                }else{
                    onBridgeReady();
                }
            });
            wx.error(function (res) {
                alert("檢測出問題:" + res.errMsg);
            });
        }
    });
});

function onBridgeReady() {
    // 發送給好友
    WeixinJSBridge.on('menu:share:appmessage', shareFriend);
    // 分享到朋友圈
    WeixinJSBridge.on('menu:share:timeline', shareTimeline);
    // 分享到微博
    WeixinJSBridge.on('menu:share:weibo', shareWeibo);
}

//分享給好友
function shareFriend() {
    WeixinJSBridge.invoke('sendAppMessage',{
        "appid": appId,
        "img_url": imgUrl,
        "img_width": "200",
        "img_height": "200",
        "link": lineLink,
        "desc": descContent,
        "title": shareTitle
    }, function(res) {
        if(res.err_msg=="send_app_msg:ok"){
            // alert("發送給好友成功");
        }
    })
}

//分享到朋友圈
function shareTimeline() {
    WeixinJSBridge.invoke('shareTimeline',{
        "img_url": imgUrl,
        "img_width": "200",
        "img_height": "200",
        "link": lineLink,
        "desc": descContent,
        "title": shareTitle
    }, function(res) {
        if(res.err_msg == 'share_timeline:ok'){
            // alert("分享成功");
        }
    });
}

//分享到微博
function shareWeibo() {
    WeixinJSBridge.invoke('shareWeibo',{
        "content": descContent,
        "url": lineLink
    }, function(res) {
        if(res.err_msg == "share_weibo:ok"){
            alert("分享到微博成功");
        }
    });
}

注意：記得在【基本設置】中【ip白名單】添加自己服務器IP

不然報錯：{"errcode":40164,"errmsg":"invalid ip 120.11.26.205, not in whitelist hint: [WJWUwa08642790]"}

好的，遛遛
