  • 【微信公众平台开发】微信JS-SDK开发,信公众平台js-sdk

    根据微信开发文档步骤如下:

    1.先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。

    JS接口安全域名设置 mi.com(前面不用带www/http,域名必须备案过)

     

    2.引入JS文件
    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-1.0.0.js

     

    3.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,见附录1
        jsApiList: [] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2
    });

    注:appId从公众号里面获取,timestamp、nonceStr、signature临时通过按微信规定的规则发送url获取

    4.通过ready接口处理成功验证

    wx.ready(function(){
    
        // config信息验证后会执行ready方法,所有接口调用都必须在config接口获得结果之后,config是一个客户端的异步操作,所以如果需要在页面加载时就调用相关接口,则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口,则可以直接调用,不需要放在ready函数中。
    });



    5.通过error接口处理失败验证,测试时可以先不用这个

    wx.error(function(res){
    
        // config信息验证失败会执行error函数,如签名过期导致验证失败,具体错误信息可以打开config的debug模式查看,也可以在返回的res参数中查看,对于SPA可以在这里更新签名。
    
    });


    JS-SDK网页所有接口代码如下:

    <?php
    require_once "jssdk.php";
    $jssdk = new JSSDK("wx46c6ccb293dfsda5fd", "e5e7ad8f4b068f118939f2cec0bc98394d");	//APPID和SECRET
    $signPackage = $jssdk->GetSignPackage();
    ?>
