我试图测试以下的http请求方法
public async Task<HttpContent> Get(string url)
{
using (HttpClient client = new HttpClient())
// breakpoint
using (HttpResponseMessage response = await client.GetAsync(url))
// can't reach anything below this point
using (HttpContent content = response.Content)
{
return content;
}
}
但是,调试器似乎正在跳过第二条评论下面的代码。我使用Visual Studio 2015 RC,有什么想法吗?我也尝试检查任务窗口,什么都没看到
编辑:找到解决方案
using System;
using System.Net.Http;
using System.Threading.Tasks;
namespace ConsoleTests
{
class Program
{
static void Main(string[] args)
{
Program program = new Program();
var content = program.Get(@"http://www.google.com");
Console.WriteLine("Program finished");
}
public async Task<HttpContent> Get(string url)
{
using (HttpClient client = new HttpClient())
using (HttpResponseMessage response = await client.GetAsync(url).ConfigureAwait(false))
using (HttpContent content = response.Content)
{
return content;
}
}
}
}
原来,因为这是一个C#控制台应用程序,它在主线程结束后结束我想,因为在添加Console.ReadLine()并稍等一下之后,请求确实返回了。我猜想C#会等到我的任务执行而不是在它之前结束,但我想我错了。如果有人能详细说明为什么会这样,那就太好了。
