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: 93xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(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();
