h5如何实现数据安全加密传输

h5利用api接口实现数据加密传输，具体方法如下：

function CurlPost($url, $param = null, $timeout = 10){//初始化curl$curl = curl_init();curl_setopt($curl, CURLOPT_URL, $url); // 设置请求的路径curl_setopt($curl, CURLOPT_POST, 1); //设置POST提交curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //显示输出结果curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);//提交数据if (is_array($param)) {curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($param));} else {curl_setopt($curl, CURLOPT_POSTFIELDS, $param);}//执行请求$data = $data_str = curl_exec($curl);//处理错误if ($error = curl_error($curl)) {$log_data = array('url' => $url,'param' => $param,'error' => '' . $error . '',);}# 关闭CURLcurl_close($curl);//json数据转换为数组$data = json_decode($data, true);//api返回数据解密$api_des = config('api.mcrypt');if ($api_des['is_open']) {$data1 = Des::decode($data, $api_des['key'], $api_des['iv']);$des_str = json_decode($data1, true);}if (!is_array($des_str)) {$des_str = $data_str;}return $des_str;}

如需要确保数据不出现泄露，还可以在数据传输中添加数据签名

//添加数据签名function makeClientSign($param){//数组排序ksort($param)//转换成json串$json_str = json_encode($param);//md5生成sign$md5_result = md5($json_str);return $md5_result;}
