使用curl工具调试https接口

工作中需要对接调试http接口,之前都是写代码测试,发现直接用curl这个工具更简单高效。

举例如下:

想要post一包数据给这个接口https://XXXXXXXXX

http报文头规定如下:

POST / HTTP/1.1
Host: XXXXXXXXXX:XXXX
Accept: */*
User-Agent: Donjin Http 0.1

Content-Type: x-ISO-TPDU/x-auth

 Cache-Control: no-cache

Content-Length: 93

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(hex data)

用curl测试:其中需要提交的二进制数据,为了方便,写到aaa.bin文件中了。

 curl https://XXXXXXXXX -v --cacert ./UP.pem -k -H 'User-Agent: Donjin Http 0.1' -H 'Content-Type: x-ISO-TPDU/x-auth' -H 'Cache-Control: no-cache' -H 'Content-Length: 93' --data-binary @aaa.bin


相比之前,用php写了个测试demo来说,这个工具更简单高效。

之前的php demo如下:

";
/* PHP CURL HTTPS POST */
function curl_post_https($url,$data){ // 模拟提交数据函数
    $curl = curl_init(); // 启动一个CURL会话
    curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查
    //curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); // 从证书中检查SSL加密算法是否存在
    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
    curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
    curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包
    curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环
    curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    $tmpInfo = curl_exec($curl); // 执行操作
    if (curl_errno($curl)) {
        echo 'Errno'.curl_error($curl);//捕抓异常
    }
    curl_close($curl); // 关闭CURL会话
    return $tmpInfo; // 返回数据,json格式
}
//echo getcwd();
/**

 */
function curl_post_ssl($url, $data, $second=30,$aHeader=array())
{
	$ch = curl_init();
	curl_setopt($ch,CURLOPT_VERBOSE,'1');
	  
	curl_setopt($ch,CURLOPT_TIMEOUT,$second);

               'Cache-Control: no-cache',
               'Content-Length: ' . strlen($data))
      );
	  
	if( count($aHeader) >= 1 ){
			curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);
	}

    }
	curl_close($ch);
	if($data)
		return $data;
	else   
		return false;
}

/*

$rcode = curl_post_ssl($url,$data,10,$aHeader);
if($rcode)

*/

function hex2bin($h){
	if (!is_string($h)) return null;
		$r='';
		for ($a=0; $a";
	echo $rcode;
	//$myStr="";  
	//for($i=0;isset($rcode[$i]);$i++)

使用c语言的测试如下:
