unity+上传数据到服务器（string、对象、文件）

1.string方式

首先去下载LitJson.dll，放在Plugins 目录下；

LitJson可以从下面的地址获得：http://download.csdn.net/detail/h570768995/9373927

然后我们定义json格式，比如我们需要如下格式：

{"intValue":345,"longValue":345679876,"stringValue":"xiaoxian","byteValue":'v',"doubleValue":345.87}

public class MessageJson
{
    public int intValue;
    public long longValue;
    public string stringValue;
    public byte byteValue;
    public double doubleValue;
}

然后在方法中声明该类，接着将其映射为Json格式：

        MessageJson msgJson = new MessageJson();
        msgJson.intValue = 20;
        msgJson.longValue = 10000000000000L;
        msgJson.stringValue = "chenhao";
        msgJson.byteValue = (byte)msgJson.intValue;
        msgJson.doubleValue = 3153456.125651;
 
        string jsonDataPost = JsonMapper.ToJson(msgJson);

如此将该数据传送出去：

WWW www = new WWW("http://192.168.1.192:18080/test",Encoding.UTF8.GetBytes(jsonDataPost));

接着等待数据，并可以打印出来：

       while(!www.isDone)
        {
            Debug.Log("wait");
        }
        yield return www;
        if(www.error!=null)
        {
            Debug.LogError(www.error);
        }
        else
        {
            Debug.Log(www.text);
//取数据1
            MessageJson msgJsonRecieve = JsonMapper.ToObject<MessageJson>(www.text);
 
            Debug.Log(msgJsonRecieve.intValue);
            Debug.Log(msgJsonRecieve.longValue);
            Debug.Log(msgJsonRecieve.stringValue);
            Debug.Log(msgJsonRecieve.byteValue);
            Debug.Log(msgJsonRecieve.doubleValue);
//取数据2
            JsonData jsonData = JsonMapper.ToObject(www.text);
            if (jsonData["stringValue"] != null)
            {
                Debug.Log(jsonData["stringValue"].ToString());
             }

JsonMapper映射可以无视排序问题，它只看“键值对”中的键。

            }
            yield return www;
            if (www.error != null)
            {
                Debug.LogError(www.error);
                IsOfflineUploadDataSuccess = false;

            }
            else
            {
                Debug.LogError(www.text);
                //取数据1
                OfflineGameStatus OfflineGameStatusref = JsonMapper.ToObject<OfflineGameStatus>(www.text);
                Debug.LogError(OfflineGameStatusref.staffNumber);

3.Unity使用UnityWebRequest上传文件到服务器的简单实现流程

前言
我在以前的项目中写过有关上传图片到服务器的功能，但是没有写过上传其他类型的文件到服务器上的功能。今天为了实现一个上传gif图片的功能，我在网上查找资料，找到了一种使用UnityWebRequest上传文件的方法。这个方法真是太有用处了，可以说是什么文件都通用，于是我在这里赶紧记录一下，方便以后使用。

实现步骤
1.实现步骤很简单，以下是我自己很据网上的资料写的脚本，完成后将此脚本挂载到场景中的物体上，代码如下所示：

using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using UnityEngine.Networking;


public class UpGifManager : MonoBehaviour
{
    string url = "服务器链接，服务端会提供！";

    /// <summary>
    /// 上传到服务器
    /// </summary>
    public void ToShengGif()
    {
        StartCoroutine(UploadVideo());
    }

    // 上传视频
    IEnumerator UploadVideo()
    {
        byte[] gifByte = File.ReadAllBytes("E:/Work/ffepgtest/gif/a.gif");
        WWWForm form = new WWWForm();
        //根据自己长传的文件修改格式
        form.AddBinaryData("file", gifByte, "myGif.mp4", "a/gif");

        using (UnityWebRequest www = UnityWebRequest.Post(url, form))
        {
            yield return www.SendWebRequest();

            if (www.isNetworkError || www.isHttpError)
            {
                Debug.Log(www.error);
            }
            else
            {
                string text = www.downloadHandler.text;
                Debug.Log("服务器返回值" + text);//正确打印服务器返回值
            }
        }
    }
}

发送成功后会有提示。

（注：发送Json方式也是一样将地址改变就行.json）

 /// <summary>
    /// 直接上传整个Json文件到服务器,正式使用
    /// </summary>
    /// <returns></returns>
    IEnumerator NewNewUpLoad()
    {
        byte[] jsonByte = File.ReadAllBytes(Application.persistentDataPath + "/" + "OfflineData" + "_" + ARGlobalData.SuccessScanUserID + ".json");
        WWWForm form = new WWWForm();
        //根据自己长传的文件修改格式
        form.AddBinaryData("file", jsonByte, "stepNoPhoto.json", "stepNoPhoto/json");

        using (UnityWebRequest www = UnityWebRequest.Post(ARGlobalData.NewConfigurePathStr + "/TPlant-inspect/api/inspect/importData", form))
        {
            yield return www.SendWebRequest();

            if (www.isNetworkError || www.isHttpError)
            {
                Debug.Log("服务器上传失败" + www.error);
                IsOfflineUploadDataSuccess = false;
            }
            else
            {
                Debug.Log("成功");
                //string text = www.downloadHandler.text;
                IsOfflineUploadDataSuccess = true;
                //Debug.Log("服务器返回值" + text);//正确打印服务器返回值
            }
        }

    }
