- 首先配置公众号
-
- JS接口安全域名
- 设置ip白名单
- 其次配置接口

- 配置JSSDK
- 最后html分享页面联调
- 常见错误

- invalid credential, access_token is invalid or not latest hint
首先配置公众号
JS接口安全域名
接入jssdk时，就需要配置JS接口安全域名，因此需要登录微信公众平台，在公众号设置→功能设置中，填写JS接口安全域名，域名即为H5项目的域名（如：www.baidu.com）,同时需要下载一个txt验证文件，并放置到服务器的根路径下，实际操作时根据提示即可。
设置ip白名单
这一步其实应该放到后面获取access_token步骤中，我这里正好已经登录在公众号平台，所以就一并操作了。后面讲到获取access_token和jsapi_ticket时，需要访问服务器，因此需要将H5项目服务器的IP地址添加到白名单中，否则接口将无法调用成功。具体设置方法：在开发→基本设置→IP白名单中进行添加相应的IP地址即可。如下图所示
其次配置接口
我用的是yii2框架
<?php
//引用JSSDK
use app\weixinapi\wxconfigs\JSSDK;
//请求当前接口的网址路径
$post_url=$post['url'];
//配置的公众号或订阅号的AppID和AppSecret 设置成自己的
$jssdk = new JSSDK("AppID", "AppSecret");
$signPackage = $jssdk->GetSignPackage($post_url);
$data['signPackage'] = $signPackage;
$result=array('status' => 0, 'msg' => 'success！', 'data' => [$data])
return $result;
配置JSSDK
<?php
namespace app\weixinapi\wxconfigs;
class JSSDK
{
private $appId;
private $appSecret;
public function __construct($appId, $appSecret)
{
$this->appId = $appId;
$this->appSecret = $appSecret;
}
public function getSignPackage($post_url)
{
$jsapiTicket = $this->getJsApiTicket();
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
// $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$url = $post_url;
$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=$url";
log::writeLog('getSignPackage的$string===' . $string);
$signature = sha1($string);
$signPackage = array(
"appId" => $this->appId,
"nonceStr" => $nonceStr,
"timestamp" => $timestamp,
"url" => $url,
"signature" => $signature,
"rawString" => $string
);
return $signPackage;
}
private function createNonceStr($length = 16)
{
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$str = "";
for ($i = 0; $i < $length; $i++) {
$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return $str;
}
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
$data = json_decode(file_get_contents(Yii::$app->basePath . "/weixinapi/wxconfigs/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";
log::writeLog('getJsApiTicket的$url===' . $url);
$res = json_decode($this->httpGet($url));
$ticket = $res->ticket;
log::writeLog('$ticket===' . $ticket);
if ($ticket) {
$data->expire_time = time() + 7000;
$data->jsapi_ticket = $ticket;
$fp = fopen(Yii::$app->basePath . "/weixinapi/wxconfigs/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
$data = json_decode(file_get_contents(Yii::$app->basePath . "/weixinapi/wxconfigs/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";
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";
log::writeLog('getAccessToken的$url===' . $url);
$res = json_decode($this->httpGet($url));
$access_token = $res->access_token;
log::writeLog('$access_token==' . $access_token);
if ($access_token) {
$data->expire_time = time() + 7000;
$data->access_token = $access_token;
$fp = fopen(Yii::$app->basePath . "/weixinapi/wxconfigs/access_token.json", "w");
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;
}
}

常见错误
invalid credential, access_token is invalid or not latest hint
是由于access_token过期了，导致生成的签名失败。分析上面的代码，发现将获取到的access_token缓存到localstorage的逻辑是有问题的，获取到的access_token默认有效期为2小时，如果重新请求API接口，新的access_token会覆盖原来的值，而我将access_token存入localstorage后，其实并没有做进一步的有效期的校验和定时刷新，所以过了有效期之后，自然就会出现上面的那个错误了
