cURL error 56: SSLRead() return error -9806

[hbliang]

我用的环境

PHP 版本：5.6.18
overtrue/wechat 版本：3.1

## 问题及现象

$material->uploadArticleImage($filename)；
使用上面的方法，经常性报错**（cURL error 56: SSLRead() return error -9806 ）**，偶尔上传成功。

easywechat upload fail:

easywechat upload success:

我利用原生的curl上传，没有任何问题。甚是奇怪。

        $media = new \CURLFile($filename);
        $url = 'api.wechat.....';

        $curl = curl_init();

        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_HTTPHEADER,['Content-Type: multipart/form-data']);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, ['media' => $media]);

        $r = curl_exec($curl);

        curl_close($curl);

另外，$material->uploadImage($filename);此方法也ok，没任何问题。

另外，我dump了\GuzzleHttp\Handler\CurlFactory.php->public static function finish()->$easy->response

发现header参数为空，是否有影响呢？

可参考https://easywechat.org/zh-cn/docs/troubleshooting.html

已经参考过了。。。问题还是没有解决

[ac1982]

你这个情况是单次偶发，还是在循环中偶发？

@ac1982
我发现是上传这一张图片的时候，经常性报错，偶尔可以上传成功。
甚是奇怪。
你试试用这图片上传。
图片如下。

[ac1982]

现在云服务商都有图片甄别功能，比如敏感信息或者之类的。
你这句是提示类信息，我个人觉得根本不需要图片去实现它，一段html不是更好吗？
上传错误的问题，我这里并没有重现。

@ac1982
刚测试了一下。上传了一张写着“色情”两字的图片，也报同样的错误。估计微信那边会过滤掉一些有敏感信息的照片。
另外，关于一段html确实是更好。。。但是公司的编辑不会写html。。。

[ac1982]

他们不会写html，你就给他们个示例嘛，这样也省去你很多烦恼不是。这个Issue只能帮你到这里了。

@ac1982 thx啦
