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 echo "hello test 111!"; echo "<br>"; /* 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(); /** * @name ssl Curl Post数据 * @param string $url 接收数据的api * @param string $vars 提交的数据 * @param int $second 要求程序必须在$second秒内完成,负责到$second秒后放到后台执行 * @return string or boolean 成功且对方有返回值则返回 */ function curl_post_ssl($url, $data, $second=30,$aHeader=array()) { $ch = curl_init(); curl_setopt($ch,CURLOPT_VERBOSE,'1'); curl_setopt($ch,CURLOPT_TIMEOUT,$second); //curl_setopt($ch,CURLOPT_VERBOSE, '1'); //debug模式，方便出错调试 curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); //curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM'); //curl_setopt($ch,CURLOPT_SSLCERT,getcwd().'/cert/CUP_cacert.pem'); // curl_setopt($ch,CURLOPT_SSLCERTPASSWD,''); curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM'); curl_setopt($ch,CURLOPT_SSLKEY,getcwd().'/cert/CUP_cacert.pem'); //设置header信息 curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'User-Agent: Donjin Http 0.1', 'Content-Type: x-ISO-TPDU/x-auth', 'Cache-Control: no-cache', 'Content-Length: ' . strlen($data)) ); if( count($aHeader) >= 1 ){ curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader); } curl_setopt($ch,CURLOPT_POST, 1); curl_setopt($ch,CURLOPT_POSTFIELDS,$data); $data = curl_exec($ch); //$curlInfo = curl_getinfo($ch); //echo $curlInfo; if (curl_errno($ch)) { echo 'Errno'.curl_error($ch);//捕抓异常 } curl_close($ch); if($data) return $data; else return false; } /* $data = [0,1]; $aHeader =[]; $rcode = curl_post_ssl($url,$data,10,$aHeader); if($rcode) { echo "ok"! } else { echo "error"! } */ function hex2bin($h){ if (!is_string($h)) return null; $r=''; for ($a=0; $a<strlen($h); $a+=2) { $r.=chr(hexdec($h{$a}.$h{($a+1)})); } return $r; } function Hex2String($hex){ $string=''; for ($i=0; $i < strlen($hex)-1; $i+=2){ $string .= chr(hexdec($hex[$i].$hex[$i+1])); } return $string; } function hextostr($hex) { return preg_replace_callback('/\\\x([0-9a-fA-F]{2})/', function($matches) { return chr(hexdec($matches[1])); }, $hex); } $string = "005BXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX0303135393838303231303031303231303136300011000000010030002953657175656e6365204e6f3136333135305358582d34433330343131390003303120"; $data = hex2bin($string); #var_dump($data); $url = 'https://XXXXXXXXXXXXXXXXX'; $aHeader = array(); $rcode = curl_post_ssl($url,$data,10,$aHeader); //$rcode = curl_post_https($url,$data); if($rcode) { echo "ok"; echo "<br>"; echo $rcode; //$myStr=""; //for($i=0;isset($rcode[$i]);$i++) //{ // $myStr.= chr($rcode[$i]); //} //var_dump($myStr); //$res=json_decode($rcode,true); echo "<br>"; echo 'respond hex data:'; echo "<br>"; $arr1 = str_split($rcode, 1); foreach($arr1 as $akey=>$aval){ $arr1[$akey]=" ".bin2hex($aval); echo $arr1[$akey]; } //var_dump($arr1); //echo hextostr($rcode); //var_dump($rcode); //echo Hex2String($rcode); //implode('!', $rcode); } else { echo "error"; echo "<br>"; }
使用c语言的测试如下：
