漏刻有时API接口实战开发系列(6)：PHP开发API接口离不开的curl函数封装

在php开发中，如果对接API接口，curl 函数是一个必须经历的门槛。先将curl 封装成函数，自动将data 进行转成json格式，同时解码成php数组输出。

get

function getUrl($url)
{
    $headerArray = array("Content-type:application/json;", "Accept:application/json");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headerArray);
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output, true);
    return $output;
}

post

function postUrl($url, $data)
{
    $data = json_encode($data);
    $headerArray = array("Content-type:application/json;charset='utf-8'", "Accept:application/json");
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headerArray);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($curl);
    curl_close($curl);
    return json_decode($output, true);
}

put

function putUrl($url, $data)
{
    $data = json_encode($data);
    $ch = curl_init(); //初始化CURL句柄
    curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //设为TRUE把curl_exec()结果转化为字串，而不是直接输出
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); //设置请求方式
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//设置提交的字符串
    $output = curl_exec($ch);
    curl_close($ch);
    return json_decode($output, true);
}

del

function delUrl($url, $data)
{
    $data = json_encode($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $put_url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output, true);
}

patch

function patchUrl($url, $data)
{
    $data = json_encode($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PATCH");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);     //20170611修改接口，用/id的方式传递，直接写在url中了
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output);
    return $output;
}

Done !
