authorization_code 授权码模式(即先登录获取code,再获取token)
password 密码模式(将用户名,密码传过去,直接获取token)
client_credentials 客户端模式(无用户,用户向客户端注册,然后客户端以自己的名义向’服务端’获取资源)
implicit 简化模式(在redirect_uri 的Hash传递token; Auth客户端运行在浏览器中,如JS,Flash)
refresh_token 刷新access_token
如果调用时出现oauth grant type is empty错误,一般是忘了设置grant_type,这个报错还有可能的原因还是php curl设置问题。
事实上淘宝SDK有封装curl操作,不需要自己去写这些代码。
封装的函数在TopClient中的curl()方法。
public function curl($url, $postFields = null)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($this->readTimeout) {
curl_setopt($ch, CURLOPT_TIMEOUT, $this->readTimeout);
}
if ($this->connectTimeout) {
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $this->connectTimeout);
}
//https 请求
if(strlen($url) > 5 && strtolower(substr($url,0,5)) == "https" ) {
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
}
if (is_array($postFields) && 0 < count($postFields))
{
$postBodyString = "";
$postMultipart = false;
foreach ($postFields as $k => $v)
{
if("@" != substr($v, 0, 1))//判断是不是文件上传
{
$postBodyString .= "$k=" . urlencode($v) . "&";
}
else//文件上传用multipart/form-data,否则用www-form-urlencoded
{
$postMultipart = true;
}
}
unset($k, $v);
curl_setopt($ch, CURLOPT_POST, true);
if ($postMultipart)
{
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
}
else
{
curl_setopt($ch, CURLOPT_POSTFIELDS, substr($postBodyString,0,-1));
}
}
$reponse = curl_exec($ch);
if (curl_errno($ch))
{
throw new Exception(curl_error($ch),0);
}
else
{
$httpStatusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if (200 !== $httpStatusCode)
{
throw new Exception($reponse,$httpStatusCode);
}
}
curl_close($ch);
return $reponse;
}
