WebAPI-HTTP编程模型

标签：ppc 静态 option copyto 交换 contex ide assert for 带着问题去思考，大家好！ 消息 HTTP编程模型的核心就是消息抽象，表示为：HttPRequestMessage,HttpResponseMessage.用于客户端和服务端之间交换请求和响应消息。 HttpMethod类包含了一组静态属性： 标头 消息内容 HttpContent包含了非虚拟公共方法 第一种方式用于推送方式访问原始的消息内容。将一个流传递给CopyAsync方法，然后把消息内容推送到这个流中 也可以使用ReadAsStreamAsync().拉取方式访问。这个方法异步返回一个流 ReadAsStringAsync和ReadAsByteArrayAsync-异步提供消息内容的缓冲副本。ReadAsStringAsync返回原始的字节内容，ReadAsByteArrayAsync将内容解码为字符串返回 当然也可以扩展为 public override Task WebAPI-HTTP编程模型 标签：ppc 静态 option copyto 交换 contex ide assert for 原文地址：https://www.cnblogs.com/moon3/p/12708145.html
它是什么？它包含什么？它能干什么？ private static readonly HttpMethod getMethod = new HttpMethod("GET");

Assert.True(ms.Length>0);
}
using(var client=new HttpClient())

var steam = await response.Content.ReadAsStreamAsync();
var buffer = new byte[2 * 1024];
