夺命雷公狗---微信开发55----微信js-sdk接口开发（2）接口功能介绍之签名算法

2022-09-15 17:23:07

我们JS-SDK里面其实有不少的接口

startRecord---录音

stopRecord---停止录音

playVoice---播放

pauseVoice---暂停播放

uploadImage---上传图片

downloadImage---下载图片

getLocation---得到用户的地址

hideOptionMenu---隐藏菜单

showOptionMenu---显示菜单

等等的接口

里面功能有这么多，我们可以在手册上看到如何实现的详细过程，如下图所示：

这里的步骤三也是js-sdk里面难度最大的一个步骤

里面的signature是最难的，因为里面涉及到算法，详情可以通过查看手册：

废话不多说，我们开始动工，编写一个signatrue.php，来获取他的签名

<?php

    //该文件用于创建一个合法签名

    require_once "common.php";

    require_once "get_token.php";

    $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token={$access_token}&type=jsapi";

    $res = http_request($url,null);

    //json解码,后面加true返回的是一个数组，不加true返回的是一个对象

    $res = json_decode($res,true);

    $api_ticket = $res['ticket'];

    //这是一个随机串

    $noncestr = md5(time());

    $time = time();

    //这里的url表示到时候我们调用所有接口的文件我们是写到这里面的

    $url = "http://weixin.showtp.com/jssdk.htm";

    //这是我们准备加密的串,返回的票据是两个小时内有效的

    $str1 = "jsapi_ticket={$api_ticket}&noncestr={$noncestr}&timestamp={$time}&url={$url}";

    //这里必须要输出，否则到时候无法调用

    echo "{$str1}<br />";

    //拿到签名

    $signatrue = sha1($str1);

    //这里要数出来，因为到时候要用到的

    echo "<br />{$signatrue}<br />";

然后反问这个signatrue.php即可获取到他的签名，如下图所示：

下一步我们就要来配置一个js接口安全域名，如下图所示：

如果成功后则如下所示：

然后我们去下载微信官方提供的示例源代码,就在微信js-sdk说明文档的附录六次，如下图所示：

解压后出现如下文件

我们解压后发现微信开发里面支持好及格版本的，如php，java，python和node，我们主要看php里面的源代码即可，如下图所示：

官方下载出来的我们感觉不大好用，所以做了下修改

jssdk.htm代码如下所示：
