.Net中HttpClient之SendAsync方法

先看下HttpClient在微软官方的解释:

 

 

 这个类中的方法有多个，现在主要讲 SendAsync(HttpRequestMessage request)的用法;

 示例代码:

var httpRequestMessage = new HttpRequestMessage
{
                    Method = HttpMethod.Post,
                    RequestUri = new Uri("http://192.168.0.37:54543/API/WeChat/GetXX"),
                    Content = new StringContent(data.ToJson(), Encoding.UTF8, "application/json")
};
var resp = await httpClient.SendAsync(httpRequestMessage);
string resp_body = await resp.Content.ReadAsStringAsync();

注意点是data.ToJson()的参数必须保证与被请求端一致(检查了许久这个问题)
