cURL 経由で HTTP POST 要求を送信し、応答として json 文字列を期待する単純な PHP スクリプトを用意しました (これには pecl_http/HTTPRequest のような既存のライブラリを使用したかったのですが、できませんでした)。呼び出しは一貫して 415 エラー - サポートされていないメディア タイプで失敗します。cURL を正しく構成していないと思いますが、何度も検索しても、何が間違っているのかわかりません。ここにいくつかのコードがあります:
class URLRequest
{
public $url;
public $headers;
public $params;
public $body;
public $expectedFormat;
public $method;
public function URLRequest($aUrl, array $aHeaders, array $aParams, $aFormat = "json", $isPost = false, $aBody = "+")
{
$this->url = $aUrl;
$this->headers = $aHeaders;
$this->params = $aParams;
$this->expectedFormat = $aFormat;
$this->method = ($isPost ? "POST" : "GET");
$this->body = $aBody;
}
public function exec()
{
$queryStr = "?";
foreach($this->params as $key=>$val)
$queryStr .= $key . "=" . $val . "&";
//trim the last '&'
$queryStr = rtrim($queryStr, "&");
$url = $this->url . $queryStr;
$request = curl_init();
curl_setopt($request, CURLOPT_URL, $url);
curl_setopt($request, CURLOPT_HEADER, 1);
curl_setopt($request, CURLOPT_HTTPHEADER, $this->headers);
curl_setopt($request, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($request, CURLOPT_SSL_VERIFYPEER, false);
if($this->method == "POST")
{
curl_setopt($request, CURLOPT_POST, 1);
curl_setopt($request, CURLOPT_POSTFIELDS, $this->body);
//this prevents an additions code 100 from getting returned
//found it in some forum - seems kind of hacky
curl_setopt($request, CURLOPT_HTTPHEADER, array("Expect:"));
}
$response = curl_exec($request);
curl_close($request);
preg_match("%(?<=HTTP/[0-9]\.[0-9] )[0-9]+%", $response, $code);
$resp = "";
if($this->expectedFormat == "json")
{
//parse response
}
elseif($this->expectedFormat == "xml")
{
//parse response
}
return $resp;
}
}
$url = "http://mydomain.com/myrestcall";
$query = array( "arg_1" => "test001",
"arg_2" => "test002",
"arg_3" => "test003");
$headers = array( "Accept-Encoding" => "gzip",
"Content-Type" => "application/json",
"Accept" => "application/json",
"custom_header_1" => "test011",
"custom_header_2" => "test012",
"custom_header_3" => "test013");
$body = array( "body_arg_1" => "test021",
"body_arg_2" => array("test022", "test023"),
"body_arg_3" => "test024");
$request = new URLRequest($url, $headers, $query, "json", true, $body);
$response = $request->exec();
...そして応答:
