PHP:如何提交“JSON”通过PUT方法? [英] PHP : How to submit "JSON" via the PUT method?
问题描述
我正在制作(并测试)我的小型PHP API。当提交 JSON
作为数据类型时,两种GET / POST方法都可以。
I'm making (and testing) my small PHP API. Both GET/POST methods are all fine while submitting the JSON
as data-type.
- 我无法通过
PUT $提交
JSON
数据c $ c>方法。当我这样做时,服务器端获得了空数据。 - 但是当我不使用
json
作为数据类型时,(只使用纯文本数据),然后我就可以成功接收和解析数据。 < ----((这很奇怪!))
- I cannot submit the
JSON
data viaPUT
method. When i do, the Server-side got empty data. - But when i DO NOT use
json
as data-type, (and just use the plain text data), then i can receive and parse the data, successfully. <----(( This is something weird! ))
这是我测试过的案例。
(通过PHP提交)submit.php:
(Submit via PHP) submit.php:
$data = array("fruit"=>"watermelon", "destination"=>"germany");
$data = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/api.php");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data)));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$respond = curl_exec($ch);
curl_close($ch);
print_r($respond);
(通过邮递员提交):
api .php:
$decoded_input = json_decode(file_get_contents("php://input"), true);
parse_str($decoded_input, $putdata);
header('Content-type: application/json');
echo json_encode( $putdata );
输出
Output
[]
问题
因此,似乎在服务器端接收/解析是问题。
- 如何提交JSON数据类型通过PUT方法?
- 我的服务器端是否有一些设置(
Apache + PHP
)来启用(允许) )json
数据类型在PUT
方法?
- How to submit JSON data-type via the PUT method?
- Are there some settings in my Server Side (
Apache + PHP
) to enable (to allow) thejson
data-type inPUT
method?
**我无法通过PUT方法获得JSON。非常感谢所有人的帮助。
** I just can't get JSON works via the PUT method. Thanks all for kind helps.
推荐答案
对不起,无法发表评论,无法回复。
Sorry, can't comment, Rep to low.
几个星期前我也玩过简单的API调用,并且我有一些功能来处理它们。
Some weeks ago i also played around with simple API calls and i made a little function to handle them.
public function callAPI($method, $url, $data = false) {
$ch = curl_init ();
switch ($method) {
case "POST" :
curl_setopt ( $ch, CURLOPT_POST, 1 );
if ($data) {
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, array (
'Content-Type: application/json',
'Content-Length: ' . strlen ( $data )
));
}
break;
case "PUT" :
curl_setopt ( $ch, CURLOPT_PUT, 1 );
break;
case "GET" :
//No settings required
break;
}
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
$responde = curl_exec ( $ch );
curl_close ( $ch );
return $responde;
}
似乎 PUT需要另一个设置
curl_setopt($ ch,CURLOPT_PUT,1);
AFAIK您的选项 curl_setopt($ ch,CURLOPT_CUSTOMREQUEST,PUT);
仅更改发送的字符串,而不是实际方法
AFAIK your option curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
only changes the string which is sent, not the actual method
