如何将 Content-Type 标头设置为 application/x-www-form-urlencoded？

  • 772

我想使用 keycloak 进行用户授权，我发送了一个 get 请求access_token，但收到错误Missing form parameter: grant_type，这意味着缺少正确的标头Content-Type（需要该值application/x-www-form-urlencoded）。

代码

    public function login(Request $req) {
        $url = env('KEYCLOAK_HOST').'/auth/realms/'.env('KEYCLOAK_REALM').'/protocol/openid-connect/token';
        $options = [
            'client_id' => env('KEYCLOAK_CLIENT_ID'),
            'client_secret' => env('KEYCLOAK_CLIENT_SECRET'),
            'grant_type' => env('KEYCLOAK_GRANT_TYPE'),
            'username' => $req->username,
            'password' => $req->password,
            'scope' => 'openid'
        ];
        $ch = curl_init($url);

        curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $options);

        $response = curl_exec($ch);
        $error = curl_error($ch);

        curl_close($ch);

        return response(['res' => json_decode($response), 'err' => json_decode($error)], 200)
            ->header('Content-Type', 'application/json');
    }

如何正确设置标题Content-Type的值application/x-www-form-urlencoded？

    也许这就是问题所在：

    https://www.php.net/manual/en/function.curl-setopt.php 注意：当传递数组 CURLOPT_POSTFIELDS 时，数据将被编码为 multipart/form-data ，当传递 URL 编码字符串时，数据将被编码为编码为 application/x-www-form-urlencoded

    如果我理解正确，对于 application/x-www-form-urlencoded 您需要删除：

    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);

    表格字段：

    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($options));
