如何使用HttpClient的发布数据？ [英] How to post data using HttpClient?

问题描述

我有这 HttpClient的距离的NuGet。

I have got this HttpClient from Nuget.

当我想要得到的数据我做这种方式：

When I want to get data I do it this way:

var response = await httpClient.GetAsync(url);
var data = await response.Content.ReadAsStringAsync();

但问题是我不知道如何发布数据？
我已经发送POST请求并发送它里面这些值：注释=Hello World的和 questionId = 1 。这可以是一个类的属性，我不知道。

But the problem is that I don't know how to post data? I have to send a post request and send these values inside it: comment="hello world" and questionId = 1. these can be a class's properties, I don't know.

更新我不知道如何将这些值添加到 HttpContent 作为post方法需要它。 httClient.Post（字符串，HttpContent）;

Update I don't know how to add those values to HttpContent as post method needs it. httClient.Post(string, HttpContent);

推荐答案

您需要使用方法：

await client.PostAsync(uri, content);

类似的东西：

Something like that:

var comment = "hello world";
var questionId = 1;

var formContent = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("comment", comment), 
    new KeyValuePair<string, string>("questionId", questionId) 
});

var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);

和如果u需要获得职位后的反应，你应该使用：

And if u need to get the response after post, you should use:

var stringContent = await response.Content.ReadAsStringAsync();
