HttpClient模板
引言
众所周知Unity本身的一些Library写的又烂限制又多，而call api几乎是unity开发不可避免的一个部分，所幸System.Net.Http在Build后不会有什么运行上的问题，那自然要用.NET的原生http方法了。
代码
这里的代码是一个登录和注册的API Call，有一个额外的dependency是Newtonsoft.Json，这个package请到这里下载
非Async
using Newtonsoft.Json;
using System;
using System.Net.Http;
using System.Text;
using UnityEngine;
public class UserAccountHttpClient
{
private const string signupUrl = "http://url/signup";
private const string loginUrl = "http://url/login";
private HttpClient httpClient;
public UserAccountHttpClient()
{
httpClient = new HttpClient();
}
public string Login(UserAccount userAccount)
{
try
{
// 定义HttpMethod(Post, Put, Get or Delete)
var httpRequest = new HttpRequestMessage(HttpMethod.Post, loginUrl);
// 构建HttpRequest content，这里用到了Newtonsoft.Json serialize content。
httpRequest.Content = new StringContent(JsonConvert.SerializeObject(userAccount), Encoding.Default, "application/json");
var response = httpClient.SendAsync(httpRequest).Result;
var result = response.Content.ReadAsStringAsync().Result.ToString();
Debug.Log($"Login result: {result}");
return result;
}
catch (Exception ex)
{
Debug.LogError(ex);
}
return "";
}
public string Signup(UserAccount userAccount)
{
try
{
var httpRequest = new HttpRequestMessage(HttpMethod.Post, signupUrl);
httpRequest.Content = new StringContent(JsonConvert.SerializeObject(userAccount), Encoding.UTF8, "application/json");
var response = httpClient.SendAsync(httpRequest).Result;
var result = response.Content.ReadAsStringAsync().Result.ToString();
Debug.Log($"Login result: {result}");
return result;
}
catch (Exception ex)
{
Debug.LogError(ex);
}
return "";
}
}
最后再放一个Async的方法
public async Task<string> PostTestContentAsync(MessageRequestBody content)
{
var result = string.Empty;
try
{
var httpRequest = new HttpRequestMessage(HttpMethod.Post, testUrl);
httpRequest.Content = new StringContent(JsonConvert.SerializeObject(content), Encoding.UTF8, "application/json");
var response = await httpClient.SendAsync(httpRequest);
result = response.Content.ReadAsStringAsync().Result;
}
catch(Exception ex)
{
Debug.LogError(ex);
}
return result;
}
