unity自带的UnityWebRequest提供了构成 HTTP 请求和处理 HTTP 响应。

构造函数：

public UnityWebRequest(); public UnityWebRequest(Uri uri); public UnityWebRequest(string url); public UnityWebRequest(Uri uri, string method); public UnityWebRequest(string url, string method); public UnityWebRequest(string url, string method, DownloadHandler downloadHandler, UploadHandler uploadHandler); public UnityWebRequest(Uri uri, string method, DownloadHandler downloadHandler, UploadHandler uploadHandler);

简单的例子：

using FF = StarEngineTec.Generic.FormatFunc; 
string url="";//请求地址
string jsonData="";//需要上传的json数据 
IEnumerator UploadPost()
{
    UnityWebRequest uwr = new UnityWebRequest(url, "POST"); 
    uwr.uploadHandler = new UploadHandlerRaw(FF.StringToBytes(jsonData));
    uwr.downloadHandler = new DownloadHandlerBuffer(); 
    //如果有请求头，根据具体字段要求设置
    uwr.SetRequestHeader("Content-Type", "application/json");
    uwr.SetRequestHeader("app-version", "V1"); 
    yield return uwr.SendWebRequest(); 
    if (uwr.isHttpError || uwr.isNetworkError)
    {
         Debug.LogError("Login Error: " + uwr.error);
    }
}

其他常用方法：

public static UnityWebRequest Post(Uri uri, Dictionary<string, string> formFields); public static UnityWebRequest Post(Uri uri, WWWForm formData); public static UnityWebRequest Post(string uri, WWWForm formData); public static UnityWebRequest Post(Uri uri, string postData); public static UnityWebRequest Post(string uri, string postData); public static UnityWebRequest Post(string uri, Dictionary<string, string> formFields);

IEnumerator Upload(string str)
{
       WWWForm form = new WWWForm();
       form.AddField("data", str); 
       UnityWebRequest webRequest = UnityWebRequest.Post(url, form); 
       yield return webRequest.SendWebRequest(); 
       if (webRequest.isHttpError || webRequest.isNetworkError)
           Debug.Log(webRequest.error);
       else       
           Debug.Log(webRequest.downloadHandler.text);
}

一般上传完数据会返回条消息，可以根据code值判断成功与否，以及请求失败的原因

Serializable特性表示该类可序列化，否则无法进行序列化

设置请求头header的Content-Type，它有四种类型： application/x-www-form-urlencoded（默认）   application/xml application/json multipart/form-data   由于该接口所传的参数为json格式，所以需要设置为application/json，否则导致报错：HTTP/1.1 415 Unsupported Media Type，下面封装发起网络请求的携程函数：

/// <summary>
/// 确认过闸
/// </summary>
[Serializable]
public class Affirm
{
    public string id;
    public string inId;
    public string time;
    public string batchCode;
}

public IEnumerator SendWebRequest()
{
    //接口地址
    string url = "http://**.**.***.***:****/********/*****";
    //post数据 通过序列化获得字符串
    string postData = JsonMapper.ToJson(new Affirm());
    //Post网络请求
    using (UnityWebRequest request = UnityWebRequest.Post(url, UnityWebRequest.kHttpVerbPOST))
    {
        byte[] postBytes = Encoding.UTF8.GetBytes(postData);
        request.uploadHandler = new UploadHandlerRaw(postBytes);
        request.downloadHandler = new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");
        yield return request.SendWebRequest();
        if (!request.isNetworkError && !request.isHttpError)
        {
            Debug.Log(response);
        }
        else
        {
            Debug.LogError($"发起网络请求失败： 确认过闸接口 -{request.error}");
        }
    }
}

当后端返回数据时，通过反序列化得到我们所需的Response类

[Serializable]
public class AffirmResponse
{
    public string msg;
    public int code;
    public bool hit;
    public List<Affirm> data;
}

public IEnumerator SendWebRequest()
{
    //接口地址
    string url = "http://**.**.***.***:****/********/*****";
    //post数据 通过序列化获得字符串
    string postData = JsonMapper.ToJson(new Affirm());
    //Post网络请求
    using (UnityWebRequest request = UnityWebRequest.Post(url, UnityWebRequest.kHttpVerbPOST))
    {
        byte[] postBytes = Encoding.UTF8.GetBytes(postData);
        request.uploadHandler = new UploadHandlerRaw(postBytes);
        request.downloadHandler = new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");
        yield return request.SendWebRequest();
        if (!request.isNetworkError && !request.isHttpError)
        {
            //反序列化
            var response = JsonMapper.ToObject<AffirmResponse>(request.downloadHandler.text);
            Debug.Log($"Code:{response.code}  Msg:{response.msg}  Hit:{response.hit}");
        }
        else
        {
            Debug.LogError($"发起网络请求失败： 确认过闸接口 -{request.error}");
        }
    }
}
