Unity之UnityWebRequest和使用官方描述：UnityWebRequest 提供了一个模块化系统，用于构成 HTTP 请求和处理 HTTP 响应。UnityWebRequest 系统的主要目标是让 Unity 游戏与 Web 浏览器后端进行交互。该系统还支持高需求功能，例如分块 HTTP 请求、流式 POST/PUT 操作以及对 HTTP 标头和动词的完全控制。阅读详情

Unity 中通过HttpWebRequest以POST形式传JSON格式（键值对格式）的参数请求数据。

注意：处理HttpWebRequest访问https有安全证书的问题（请求被中止: 未能创建 SSL/TLS 安全通道。）

只需加上以下两行代码就行了。
ServicePointManager.ServerCertificateValidationCallback += (s, cert, chain, sslPolicyErrors) => true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

POST请求实现以下要求

POST "https://....."; //提供获取Token值的服务接口地址（很重要）

入参body(json格式)：
{
"username":"后端提供",
"password":"后端提供",
"clientType": "WEB",
"pid":"01967189376"
}

  /// <summary>
    /// POST请求方法
    /// </summary>
    /// <param name="url">获取Token值的服务URL地址（很重要）</param>
    /// <param name="jsonData">传入请求的参数，此处参数为JOSN格式</param>
    public void HttpPost(string url, string jsonData)
    {
        //处理HttpWebRequest访问https有安全证书的问题（ 请求被中止: 未能创建 SSL/TLS 安全通道。）
        ServicePointManager.ServerCertificateValidationCallback += (s, cert, chain, sslPolicyErrors) => true;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

        byte[] byteArray = Encoding.UTF8.GetBytes(jsonData);
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
        httpWebRequest.Method = "POST";
        httpWebRequest.ContentType = "application/json";
        //httpWebRequest.ContentLength = byteArray.Length;  //此处注释的情况下需要调整“myResponseStream.Close();"执行顺序
        Stream myResponseStream = httpWebRequest.GetRequestStream();
        myResponseStream.Write(byteArray, 0, byteArray.Length);
        myResponseStream.Close(); //"httpWebRequest.ContentLength"未赋值的情况下需要在此处执行关闭语句；若赋值了，可以放在最后执行关闭语句---
        HttpWebResponse response = (HttpWebResponse)httpWebRequest.GetResponse();
        StreamReader myStreamReader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
        string retString = myStreamReader.ReadToEnd();
        myStreamReader.Close();
        response.Close();
        if (!string.IsNullOrEmpty(retString))
        {
            Debug.LogError(retString);
            TokenDataInfo tokenDataInfo = JsonMapper.ToObject<TokenDataInfo>(retString);
            authorization = tokenDataInfo.token_type + " " + tokenDataInfo.access_token;
            Debug.Log(authorization);
        }
    }

Unity 中通过HttpWebRequest 以GET形式传authorization 的参数请求数据。

注意：处理HttpWebRequest访问https有安全证书的问题（请求被中止: 未能创建 SSL/TLS 安全通道。）

GET请求实现以下要求

GET "https://....."; //提供请求数据的URL地址，以头文件形式发起请求进行Token验证

请求头带上
authorization

  /// <summary>
    /// GET请求
    /// ContentType = "application/json";
    /// token为Authorization中的授权验证码

    /// <param name="Url">请求数据的URL地址</param>
    /// <param name="token">token为Authorization中的授权验证码</param>
    /// <returns></returns>
    public void HttpGet(string url, string token)
    {
        //处理HttpWebRequest访问https有安全证书的问题（ 请求被中止: 未能创建 SSL/TLS 安全通道。）
        ServicePointManager.ServerCertificateValidationCallback += (s, cert, chain, sslPolicyErrors) => true;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "GET";
        //request.ContentType = "application/json";
        if (authorization != null)
        {
            request.Headers.Add("authorization", token);//请求头文件
            Debug.LogError(authorization);
        }

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        Stream myResponseStream = response.GetResponseStream();
        StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
        string retString = myStreamReader.ReadToEnd();
        myStreamReader.Close();
        myResponseStream.Close();
        response.Close();
        if (!string.IsNullOrEmpty(retString))
        {
            Debug.LogError(retString);
            GetDataInfo getDataInfo = JsonMapper.ToObject<GetDataInfo>(retString);
            Debug.LogError(getDataInfo.address["name"]);
            Debug.LogError(getDataInfo.companyInfo["companyName"]);
            Debug.LogError(getDataInfo.alarmCount);
            Debug.LogError(getDataInfo.faultCount);
        }
    }
}
