用post方式訪問只需要改三處：
1铭污、將computeSignature函數(shù)內(nèi)的拼接字符GET改成POST

 // 生成用于計算簽名的字符串 stringToSign  
$stringToSign = 'POST&%2F&' . percentencode(substr($canonicalizedQueryString, 1));  

2、將發(fā)送http請求的PHP函數(shù)https_request改為用POST方式傳：

   function https_request($url)  
{  
    $curl = curl_init();
    //設(shè)置抓取的url
    curl_setopt($curl, CURLOPT_URL, 'https://dysmsapi.aliyuncs.com');
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);  
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    //設(shè)置頭文件的信息作為數(shù)據(jù)流輸出
    curl_setopt($curl, CURLOPT_HEADER, 1);
    //設(shè)置獲取的信息以文件流的形式返回膀篮，而不是直接輸出嘹狞。
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    //設(shè)置post方式提交
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $url);
    $data = curl_exec($curl);  
    if (curl_errno($curl)) {return 'ERROR '.curl_error($curl);}  
    curl_close($curl);  
    return $data;  
}  

3、調(diào)用https_request的參數(shù)需要調(diào)整為POST要傳輸?shù)闹?/p>

$result = xml_to_array(https_request(http_build_query($data)));  

DONE誓竿！
