Java微信公众号开发(自定义分享功能)

1、登录微信公众平台配置业务域名和JS接口安全域名(不带http://)

2、 服务器配置(如果服务器配置开启,则用户发送给公众号的消息和事件都会被微信转发到配置的url中,开发者可自行处理)

 

服务器地址(URL)具体代码如下:

@Configuration

3、微信分享功能开发

(1)在需要调用JS接口的页面引入如下JS文件,(支持https):http://res.wx.qq.com/open/js/jweixin-1.4.0.js

(2)通过config接口注入权限验证配置

wx.config({
    debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。
    appId: '', // 必填,公众号的唯一标识
    timestamp: , // 必填,生成签名的时间戳
    nonceStr: '', // 必填,生成签名的随机串
    signature: '',// 必填,签名
    jsApiList: [] // 必填,需要使用的JS接口列表
});

config配置Demo

@RestController
@RequestMapping(value = "/wechat")
public class WeChatSharingController {

	@Autowired
	private WxMpService wxMpService;

	@RequestMapping(value = "/share")
	public Result share(@RequestParam("url") String url) {
		Result result = new Result();
		try {
			WxJsapiSignature signature = wxMpService.createJsapiSignature(url);
			Result.getSuccessResult(result, "请求成功", signature);
		} catch (Exception e) {
			Result.getErrorResult(result, "分享出现错误");
		}
		return result;
	}

}
$.ajax('/wechat/share', {
            data: {"url": window.location.href},
            dataType: 'json',//服务器返回json格式数据
            type: 'get',//HTTP请求类型
            timeout: 10000,//超时时间设置为10秒;
            contentType: 'application/json',
            success: function (data) {
                if (data.code == 0) {
                    wx.config({
                        debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。
                        appId: data.data.appId, // 必填,公众号的唯一标识
                        timestamp: data.data.timestamp, // 必填,生成签名的时间戳
                        nonceStr: data.data.nonceStr, // 必填,生成签名的随机串
                        signature: data.data.signature,// 必填,签名,见附录1
                        jsApiList: ['onMenuShareTimeline', 'onMenuShareAppMessage'] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2
                    });
                }
            },
            error: function (xhr, status, error) {
                //异常处理;
                console.log(error);
            }
        });

(3)通过ready接口处理成功验证

wx.ready(function() {
            wx.hideMenuItems({
                menuList: ['menuItem:share:qq','menuItem:share:weiboApp','menuItem:share:facebook','menuItem:share:QZone'] // 要隐藏的菜单项,只能隐藏“传播类”和“保护类”按钮,所有menu项见附录3
            });
            // 获取"分享到朋友圈"按钮点击状态及自定义分享内容接口
            wx.onMenuShareTimeline({
                title: '#', // 分享标题
                link: '#',
                imgUrl: '#' // 分享图标
            });


            // 获取"分享给朋友"按钮点击状态及自定义分享内容接口
            wx.onMenuShareAppMessage({
                title: '#', // 分享标题
                desc: '#', // 分享描述
                link: window.location.href,
                imgUrl: '#', // 分享图标
                type: 'link' // 分享类型,music、video或link,不填默认为link
            });
        })
