oauth2: 对 api 如何上传文件？

Question

环境是:
yii2-authclient
weibo.upload接口
感谢思路/点拨,这个问题应该不限定在yii2框架内.
接口文档：pic类型:binary描述:要上传的图片，仅支持JPEG、GIF、PNG格式，图片大小小于5M。
我的代码:
publicfunctionsendUpload($text,$url)
{
return$this->api('2/statuses/upload.json','POST',[
'status'=>$text,
'visible'=>self::VISIBLE_ALL,
'pic'=>'@'.$url,
'source'=>$this->source,
]);
}
执行后返回的错误:
{"error":"unsupportmediatype(application/x-www-form-urlencoded)","error_code":10007,"request":"/2/statuses/upload.json"}
微博提供的演示代码:
functionupload($status,$pic_path,$lat=NULL,$long=NULL)
{
$params=array();
$params['status']=$status;
$params['pic']='@'.$pic_path;
if($lat){
$params['lat']=floatval($lat);
}
if($long){
$params['long']=floatval($long);
}
return$this->oauth->post('statuses/upload',$params,true);
}
