这个错误信息 System.InvalidOperationException: An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.

通常出现在使用C#的HttpClient类进行网络请求时。

它意味着你提供的请求URI无效，或者没有设置BaseAddress。

解决方法：确保URI是是绝对URI：当你创建一个请求时，确保你提供的URI是完整的，例如：http://www.example.com/api/resource 设置BaseAddress：如果你不想在每次请求时都提供完整的URI，你可以为HttpClient实例设置一个BaseAddress。这样，你只需要提供相对于这个基础地址的路径。检查URI的格式：确保你提供的URI是有效的，并且符合URI的规范格式。使用Uri类创建URI：不要直接使用字符串作为URI。使用Uri类来创建URI，这样可以确保它是有效的。设置BaseAddress C#var client = new HttpClient(); client.BaseAddress = new Uri("http://www.example.com/api/"); var response = await client.GetAsync("resource"); 使用Uri类创建URI C#var uri = new Uri("http://www.example.com/api/resource"); var response = await client.GetAsync(uri); 浏览量 34 相关文章：
