[英]How to use HttpClient without async
Hello I'm following to this guide 您好我正在关注本指南
static async Task<Product> GetProductAsync(string path)
{
Product product = null;
HttpResponseMessage response = await client.GetAsync(path);
if (response.IsSuccessStatusCode)
{
product = await response.Content.ReadAsAsync<Product>();
}
return product;
}
I use this example on my code and I want to know is there any way to use HttpClient
without async/await
and how can I get only string of response? 我在我的代码上使用这个例子,我想知道有没有办法在没有
async/await
情况下使用HttpClient
,我怎样才能得到只有响应的字符串?
Thank you in advance 先感谢您

HttpClient
was specifically designed for asynchronous use. HttpClient
专为异步使用而设计。
If you want to synchronously download a string, use WebClient.DownloadString
. 如果要同步下载字符串,请使用
WebClient.DownloadString
。
Of course you can: 当然可以:
public static string Method(string path)
{
using (var client = new HttpClient())
{
var response = client.GetAsync(path).GetAwaiter().GetResult();
if (response.IsSuccessStatusCode)
{
var responseContent = response.Content;
return responseContent.ReadAsStringAsync().GetAwaiter().GetResult();
}
}
}
but as @MarcinJuraszek said: 但正如@MarcinJuraszek所说:
"That may cause deadlocks in ASP.NET and WinForms. Using .Result or .Wait() with TPL should be done with caution".
“这可能会导致ASP.NET和WinForms出现死锁。使用.Result或.Wait()与TPL应该谨慎”。
Here is the example with WebClient.DownloadString
以下是
WebClient.DownloadString
的示例
using (var client = new WebClient())
{
string response = client.DownloadString(path);
if (!string.IsNullOrEmpty(response))
{
...
}
}
