Connection broken: IncompleteRead(1394 bytes read)', IncompleteRead(1394 bytes read)

使用urllib3上传出现的问题

Connection broken: IncompleteRead(1394 bytes read)', IncompleteRead(1394 bytes read)

原因：网上说此问题出现的原因是服务器的请求只支持HTTP/1.0，urllib3中使用了chunk，但是chunk在HTTP/1.1中才会有，传输还没完成连接就中断了，所以报错
解决：

# 引入 http.client
import http.client
# 配置如下
http.client.HTTPConnection._http_vsn = 10
http.client.HTTPConnection._http_vsn_str = 'HTTP/1.0'
# 其他那些改代码什么都是不切实际的

这里注意的是python3以前http.client叫httplib

完整错误如下：
