错误：URI无效：无法解析主机名。如何使代码运行。 [英] Error: Invalid URI: The hostname could not be parsed. How to make the code run.
本文介绍了错误：URI无效：无法解析主机名。如何使代码运行。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
用法：请提供有效参数，例如：
customschemename：// readersIP：portname --ant 1,2
我的阅读器配置如下：
Ip：10.0.0.101本地端口：49200远程端口：5084
可执行文件：Reader.exe
当类型：Reader //10.0.0.101:49200 --ant 1， 2或
读者//10.0.0.101:5084 --ant 1,2
我得到答案：错误：URI无效：无法解析主机名。
Usage: Please provide valid arguments, such as:
customschemename://readerIP:portname --ant 1,2
I have a reader configured as follow:
Ip:10.0.0.101 Local Port:49200 Remote Port:5084
Executable file: Reader.exe
When a type: Reader //10.0.0.101:49200 --ant 1,2 or
Reader //10.0.0.101:5084 --ant 1,2
I get the answer: Error: Invalid URI: The hostname could not be parsed.

推荐答案
您没有给它一个有效的URL来解析。您继续输入：
You're not giving it a valid URL to parse. You keep typing:
//ipAddress:port
你错过了两个斜杠前面的部分：
You're missing the part that goes in front of the two slashes:
http://ipAddress:port
但是，模式名称应该取决于您尝试连接的服务器。它可以是 ftp：，或文件：，或 http：或任何其他名称。
But, what the schema name should be depends on the server that you're trying to connect to. It could be ftp:, or file:, or http:, or any other name.
