c#之WWW WebRequest UriFormatException : URI scheme must start with a letter and must consist of one of

每当从列出的类中运行下面的行时，我在版本 2017.2.0f3 和 2017.2.1f1 中遇到此错误，但它在 5.5.0.f3 中完美运行

WWW request = new WWW(m_host, bytes, HashtableToDictionary<string, string>(postHeader)); 

错误:

UriFormatException: URI scheme must start with a letter and must consist of one of alphabet, digits, '+', '-' or '.' character. 
System.Uri.Parse (UriKind kind, System.String uriString) 
System.Uri.ParseUri (UriKind kind) 
System.Uri..ctor (System.String uriString, Boolean dontEscape) 
System.Uri..ctor (System.String uriString) 

产生错误的类:

有没有其他人以前遇到过这个错误并且能够修复它？

请您参考如下方法:

问题是您未能指定 URI 方案(如 http 或 https)。

因此你必须改变:

127.0.0.1:8888 

到:

http://127.0.0.1:8888
