UnityWebRequest-Post Xml请求

本章介绍Post请求传入Xml用法
直接上代码：

using System;
using LitJson;
using System.Text;
using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
using System.IO;
using System.Xml.Serialization;
using System.Xml;

public class Test : MonoBehaviour
{
    
    
    /// <summary>
    /// 登录验证信息
    /// </summary>
    public class LoginInfo
    {
    
    
        public string userName;
        public string password;

        public LoginInfo(string userName, string password)
        {
    
    
            this.userName = userName;
            this.password = password;
        }
    }

    private void Start()
    {
    
    
        LoginInfo loginInfo = new LoginInfo("admin", "123456");
        string xmlStr = ToXml<LoginInfo>(loginInfo);

        StartCoroutine(UnityWebRequestPost("http://192.168.0.1:8080/port/login", xmlStr, text =>
        {
    
    
            Debug.Log("请求结果：" + text);
        }));
    }

    /// <summary>
    /// Xml序列化
    /// </summary>
    /// <typeparam name="T">类型</typeparam>
    /// <param name="arg">对象</param>
    /// <returns></returns>
    private string ToXml<T>(object arg)
    {
    
    
        MemoryStream memoryStream = new MemoryStream();
        XmlSerializer xs = new XmlSerializer(typeof(T));
        XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
        xs.Serialize(xmlTextWriter, arg);
        memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
        string xmlStr = Encoding.UTF8.GetString(memoryStream.ToArray());
        return xmlStr;
    }

    /// <summary>
    /// UnityWebRequest Post Xml
    /// </summary>
    /// <param name="url">接口地址</param>
    /// <param name="xmlStr">xml参数</param>
    /// <param name="textCallBack">text回调</param>
    /// <returns></returns>
    IEnumerator UnityWebRequestPost(string url, string xmlStr, Action<string> textCallBack)
    {
    
    
        byte[] bytes = Encoding.UTF8.GetBytes(xmlStr);
        UnityWebRequest request = new UnityWebRequest(url, UnityWebRequest.kHttpVerbPOST)
        {
    
    
            uploadHandler = new UploadHandlerRaw(bytes),
            downloadHandler = new DownloadHandlerBuffer()
        };
        request.SetRequestHeader("Content-Type", "application/xml;charset=utf-8");
        yield return request.SendWebRequest();
        if (request.isHttpError || request.isNetworkError)
        {
    
    
            Debug.LogError(request.error);
        }
        else
        {
    
    
            string result = request.downloadHandler.text;
            Debug.Log(result);
        }
    }
}

这里需要注意的是，和Json传入数据的区别就是MIME类型的区别以及序列化API的区别
具体怎么序列化和反序列化Xml，直接传送门：Xml数据解析
