thinkphp5框架下接入阿里云短信服务接口实现：注册登录等等

首先你的注册阿里云短信并根据项目需求购买相应的套餐，然后根据官方文档生成AccessKey。这里就不细说，主要说一下实现的过程，具体如下：

1.首先把签名助手SignatureHelper类放在如图目录下（注意这个类的命令空间namespace aliyunsms;）：

2.在需要发验证码的类里写发送的方法，根据你的实际需求可以写个公共类放进去

 

 "12345",
			
		);
		// fixme 可选: 设置发送短信流水号
		//$params['OutId'] = "12345";
	
		// fixme 可选: 上行短信扩展码, 扩展码字段控制在7位或以下，无特殊需求用户请忽略此字段
		//$params['SmsUpExtendCode'] = "1234567";
	
	
		// *** 需用户填写部分结束, 以下代码若无必要无需更改 ***
		if(!empty($params["TemplateParam"]) && is_array($params["TemplateParam"])) {
			$params["TemplateParam"] = json_encode($params["TemplateParam"], JSON_UNESCAPED_UNICODE);
		}
	
		// 初始化SignatureHelper实例用于设置参数，签名以及发送请求
		$helper = new SignatureHelper();
		
		// 此处可能会抛出异常，注意catch
		$content = $helper->request(
			$accessKeyId,
			$accessKeySecret,
			"dysmsapi.aliyuncs.com",
			array_merge($params, array(
				"RegionId" => "cn-hangzhou",
				"Action" => "SendSms",
				"Version" => "2017-05-25",
			)),
			$security
		);
		return $content;
    }
}

到这里就可以了。

下面是SignatureHelper.php累的具体代码

 "HMAC-SHA1",
            "SignatureNonce" => uniqid(mt_rand(0,0xffff), true),
            "SignatureVersion" => "1.0",
            "AccessKeyId" => $accessKeyId,
            "Timestamp" => gmdate("Y-m-d\TH:i:s\Z"),
            "Format" => "JSON",
        ), $params);
        ksort($apiParams);
        $sortedQueryStringTmp = "";
        foreach ($apiParams as $key => $value) {
            $sortedQueryStringTmp .= "&" . $this->encode($key) . "=" . $this->encode($value);
        }

        $stringToSign = "${method}&%2F&" . $this->encode(substr($sortedQueryStringTmp, 1));

        $sign = base64_encode(hash_hmac("sha1", $stringToSign, $accessKeySecret . "&",true));

        $signature = $this->encode($sign);

        $url = ($security ? 'https' : 'http')."://{$domain}/";

        try {
            $content = $this->fetchContent($url, $method, "Signature={$signature}{$sortedQueryStringTmp}");
            return json_decode($content);
        } catch( \Exception $e) {
            return false;
        }
    }

    private function encode($str)
    {
        $res = urlencode($str);
        $res = preg_replace("/\+/", "%20", $res);
        $res = preg_replace("/\*/", "%2A", $res);
        $res = preg_replace("/%7E/", "~", $res);
        return $res;
    }

    private function fetchContent($url, $method, $body) {
        $ch = curl_init();

        if($method == 'POST') {
            curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
            curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
        } else {
            $url .= '?'.$body;
        }

        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_TIMEOUT, 5);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            "x-sdk-client" => "php/2.0.0"
        ));

        if(substr($url, 0,5) == 'https') {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        }

        $rtn = curl_exec($ch);

        if($rtn === false) {
            // 大多由设置等原因引起，一般无法保障后续逻辑正常执行，
            // 所以这里触发的是E_USER_ERROR，会终止脚本执行，无法被try...catch捕获，需要用户排查环境、网络等故障
            trigger_error("[CURL_" . curl_errno($ch) . "]: " . curl_error($ch), E_USER_ERROR);
        }
        curl_close($ch);

        return $rtn;
    }
}
