微信在6.0.2.58版本以后开始使用新的api，在Android系统中不能用以前的代码来自定义分享内容了。
现在自定义内容的方法走的是公众号的一套流程
1获取access_token
2得到token后获取jsapi_ticket
3得到ticket后将ticket用sha1算法加密。
这里加密的数据是ticket+time()+随机字符串+url
code：
<?php
require_once "jssdk.php";
$jssdk = new JSSDK("APPID","APPSECRET");
$signPackage = $jssdk->GetSignPackage();
?>
<!DOCTYPE html>
<html lang="en"> .. <script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
wx.config({
debug: true,
appId: '<?php echo $signPackage["appId"];?>',
timestamp: <?php echo $signPackage["timestamp"];?>,
nonceStr: '<?php echo $signPackage["nonceStr"];?>',
signature: '<?php echo $signPackage["signature"];?>',
jsApiList: [
// 所有要调用的 API 都要加到这个列表中
'onMenuShareTimeline',
'onMenuShareAppMessage',
'onMenuShareQQ',
'onMenuShareWeibo'
]
});
//自定义内容
var dataForWeixin = {
title: title,
desc: desc,
imgUrl: imgUrl,
link: link
};
wx.ready(function () {
wx.onMenuShareTimeline({
title: dataForWeixin.title, // 分享标题
link: dataForWeixin.link, // 分享链接
imgUrl: dataForWeixin.imgUrl
});
wx.onMenuShareAppMessage({
title: dataForWeixin.title,

imgUrl: dataForWeixin.imgUrl
});
wx.onMenuShareWeibo({
title: dataForWeixin.title,
desc: dataForWeixin.desc,
link: dataForWeixin.link,
imgUrl: dataForWeixin.imgUrl
});

jssdk.php：
<?php

private $appSecret; public function __construct($appId, $appSecret) {
$this->appId = $appId;
$this->appSecret = $appSecret;

$jsapiTicket = $this->getJsApiTicket(); // 注意 URL 一定要动态获取，不能 hardcode.
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
$url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $timestamp = time();
$nonceStr = $this->createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序
$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url"; $signature = sha1($string); $signPackage = array(
"appId" => $this->appId,
"nonceStr" => $nonceStr,
"timestamp" => $timestamp,
"url" => $url,

return $signPackage;
} private function createNonceStr($length = 16) {

} private function getJsApiTicket() {
// jsapi_ticket 应该全局存储与更新，以下代码以写入到文件中做示例
$data = json_decode(file_get_contents("jsapi_ticket.json"));
if ($data->expire_time < time()) {
$accessToken = $this->getAccessToken();
// 如果是企业号用以下 URL 获取 ticket
// $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken";
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";

if ($ticket) {
$data->expire_time = time() + 7000;
$data->jsapi_ticket = $ticket;
$fp = fopen("jsapi_ticket.json", "w");
fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$ticket = $data->jsapi_ticket;
} return $ticket;
} private function getAccessToken() {
// access_token 应该全局存储与更新，以下代码以写入到文件中做示例
$data = json_decode(file_get_contents("access_token.json"));
if ($data->expire_time < time()) {
// 如果是企业号用以下URL获取access_token
// $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";

fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$access_token = $data->access_token;
}
return $access_token;
} private function httpGet($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl);
curl_close($curl); return $res;
}
}
同时为了减少服务器压力，将获取到的token和ticket保存在本地
{"access_token":"","expire_time":0}
{"jsapi_ticket":"","expire_time":0}
效果
