php同curl post 發送json並返回json數據實例

<?php
$arr = array(
    'subject'=>'課程',
    'loginName'=>'Durriya',
    'password'=>'123'
);

//json也可以
$data_string =  json_encode($arr);
//普通數組也行
//$data_string = $arr;

echo $data_string;
//echo '<br>';

//curl驗證成功
$ch = curl_init("http://test.api.com/");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string)
));

$result = curl_exec($ch);
if (curl_errno($ch)) {
    print curl_error($ch);
}
curl_close($ch);
echo $result;

接上面的curl依然可以訪問成功

//curl驗證成功
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "http://hzgwyw.gensee.com/integration/site/training/room/created");
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,$data_string);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json; charset=utf-8',
        'Content-Length: ' . strlen($data_string)
    )
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$res = curl_exec($curl);
curl_close($curl);
echo $res;

以上是在隨便一個php頁面中可以實現的，在Thinkphp中所做的項目測試不支持頭部的定義，然后又有一種新的curl格式也可以提交成功，但是都已數組的形式可以實現

$ch = curl_init ();
        curl_setopt ( $ch, CURLOPT_URL, $url );
        curl_setopt ( $ch, CURLOPT_POST, 1 );
        curl_setopt ( $ch, CURLOPT_HEADER, 0 );
        curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
        curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data_string );
        $response = curl_exec($ch);
        if (curl_errno($ch)) {
            print curl_error($ch);
        }
        curl_close($ch);

做接口測試的過程中遇到的問題：

使用表單提交的方式:（可以是json，也可以是數組）

1）提交后將值轉化為數組--->對數組轉義json_encode($arr);成json數據可以實現，

2）提交后將值轉化為數組--->不進行轉義直接以數組的形式：兩種方法都可以實現

直接對變量賦值得到數組（不可以json數據）

 

以上三種經驗證都可以將數據輸出成json格式

<?php
$data = array("subject" => "nihao", 
              "startDate" => "2016-10-12 22:22:22",
              "loginName"=>'[e-mail]',
              "password"=>'hzgwyw',
              );
$data_string = $data;

$url = "http://hzgwyw.gensee.com/integration/site/training/room/created";
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data_string );
$response = curl_exec($ch);
if (curl_errno($ch)) {
    print curl_error($ch);
}
curl_close($ch);
echo $response;
