oauth2:对api如何上传文件？

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:

public function sendUpload($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":"unsupport mediatype (application/x-www-form-urlencoded)","error_code":10007,"request":"/2/statuses/upload.json"}

微博提供的演示代码:

function upload( $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 );
}

你需要 multipart/form-data.
