0.APICloud簡介

• 可以利用它簡單的搭建弱聯(lián)網(wǎng)服務(wù)器,存儲(chǔ)一些基本資料和 制作推送.
• APICloud服務(wù)器:APICloud利用了又拍云和七牛云,制作了一個(gè)通用的Web服務(wù)器,并且開放了一些API讓開發(fā)者使用.
• APICloud客戶端:使用她提供的Html5 API制作跨平臺(tái)客戶端;這點(diǎn)我們暫時(shí)是用不到.
• APICloud官網(wǎng): http://www.apicloud.com/

1.在Unity中使用APICloud

由于APICloud官方的C#的SDK使用了高版本的.net; mono的.net很多沒有實(shí)現(xiàn),所以在Unity中不能使用官方的SDK.
需要自己重新寫,好再官網(wǎng)的文檔還是很齊全的.
其中用到了LitJson,具體的使用可以看我的另一篇文章:在Unity中解析和封裝Json

a.制作一個(gè)ApiCloudKey類用于生成驗(yàn)證Key

把其中的AppID和AppKey替換成你自己的就可以了

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Security.Cryptography;
using System.Text;
using LitJson;

public class ApiCloudKey {
    public static string AppID = "A12345667890"; 
    public static string AppKey = "AAAAAA01111-XXXX-XXXX-XXXX-XXXXXX";
    public static string UrlPush = "https://p.apicloud.com/api/push/message";
    public static string UrlMcm = "https://d.apicloud.com/mcm/api";

    public static string X_APICloud_AppKey
    {
        get
        {
            long amp = (long)(System.DateTime.Now - new System.DateTime(1970, 01, 01)).TotalMilliseconds;
            string value = AppID + "UZ" + AppKey + "UZ" + amp;
            byte[] buffer = SHA1.Create().ComputeHash(Encoding.UTF8.GetBytes(value));
            StringBuilder builder = new StringBuilder();
            foreach (byte num in buffer)
            {
                builder.AppendFormat("{0:x2}", num);
            }
            return builder.ToString() + "." + amp;
        }
    }

    public static Dictionary<string, string> Headers
    {
        get
        {
            Dictionary<string, string> header = new Dictionary<string, string>();
            header["Content-Type"] = "application/json";
            header["X-APICloud-AppId"] = AppID;
            header["X-APICloud-AppKey"] = X_APICloud_AppKey;
            return header;
        }
    }
}

b.制作一個(gè)ApiCloudMcm連接ApiCloud的Mcm服務(wù)(用戶數(shù)據(jù)庫)

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Security.Cryptography;
using System.Text;
using LitJson;

public class ApiCloudMcm {
    //1 向服務(wù)器發(fā)送一個(gè)json以創(chuàng)建一個(gè)例，如果className=user,就會(huì)創(chuàng)建一個(gè)用戶,如果是user，就必須有賬號(hào)密碼
    public static WWW CreateNewInstance(string ClassName, string Body)  
    {
        string url = ApiCloudKey.UrlMcm + "/" + ClassName;
        byte[] postData = Encoding.UTF8.GetBytes(Body);
        WWW www = new WWW(url, postData, ApiCloudKey.Headers);
        return www;
    }

    //2 更新一個(gè)ID下的內(nèi)容
    public static WWW UpdateAttributeOfAinstanceByID(string ClassName, string Body, string ID)    
    {
        string url = ApiCloudKey.UrlMcm + "/" + ClassName + "/" + ID;
        byte[] postData = Encoding.UTF8.GetBytes(Body);

        Dictionary<string, string> header = new Dictionary<string, string>();
        header["X-HTTP-Method-Override"] = "PUT";  //(or PATCH, DELETE, GET, POST, etc)
        header["Content-Type"] = "application/json";
        header["X-APICloud-AppId"] = ApiCloudKey.AppID;
        header["X-APICloud-AppKey"] = ApiCloudKey.X_APICloud_AppKey;
        WWW www = new WWW(url, postData, header);
        return www;
    }

    //4 檢查某個(gè)ID是否存在
    public static WWW CheckWhetherInstanceExist(string ClassName, string ID)   
    {
        string url = ApiCloudKey.UrlMcm + "/" + ClassName + "/" + ID + "/exists";
        WWW www = new WWW(url, null, ApiCloudKey.Headers);
        return www;
    }

    //6獲取一個(gè)實(shí)例的內(nèi)容，用id獲取
    public static WWW FindInstanceByID(string ClassName, string ID)
    {
        string url = ApiCloudKey.UrlMcm + "/" + ClassName+"/"+ ID;
        WWW www = new WWW(url, null, ApiCloudKey.Headers);
        return www;
    }

    //7刪除一個(gè)實(shí)例的內(nèi)容，用id刪除
    public static WWW DeleteInstanceByID(string ClassName, string ID)
    {
        string url = ApiCloudKey.UrlMcm + "/" + ClassName + "/" + ID;
        var data = new { _method = "DELETE"};
        string strData = JsonMapper.ToJson(data);
        byte[] postData = Encoding.UTF8.GetBytes(strData);
        WWW www = new WWW(url, postData, ApiCloudKey.Headers);
        return www;
    }

    //8 user登錄
    public static WWW LoginUser(string name, string word)
    {
        string url = ApiCloudKey.UrlMcm + "/user/login";
        var data = new { username = name, password = word};
        string strData = JsonMapper.ToJson(data);
        byte[] postData = Encoding.UTF8.GetBytes(strData);

        Dictionary<string, string> header = new Dictionary<string, string>();
        header["X-HTTP-Method-Override"] = "POST";  //(or PATCH, DELETE, GET, POST, etc)
        header["Content-Type"] = "application/json";
        header["X-APICloud-AppId"] = ApiCloudKey.AppID;
        header["X-APICloud-AppKey"] = ApiCloudKey.X_APICloud_AppKey;

        WWW www = new WWW(url, postData, header);
        return www;
    }

    //9 user登出/注銷
    public static WWW LogoutUser(string ID)
    {
        string url = ApiCloudKey.UrlMcm + "/user/logout";
        Dictionary<string, string> header = new Dictionary<string, string>();
        header["Content-Type"] = "application/json";
        header["authorization"] = ID;
        header["X-APICloud-AppId"] = ApiCloudKey.AppID;
        header["X-APICloud-AppKey"] = ApiCloudKey.X_APICloud_AppKey;
        WWW www = new WWW(url, null, ApiCloudKey.Headers);
        return www;
    }
}

c.使用ApiCloudMcm中的方法和服務(wù)器進(jìn)行交互

void Start () {
    WWW www = ApiCloudMcm.CreateNewInstance("user", jsobj.userDataString);
    StartCoroutine(CallBack(www));
}

IEnumerator CallBack(WWW www){
    yield return www;
    Debug.Log (www.text); 
    //自行解析www.text做各種數(shù)據(jù)判斷和處理
}

2.可能會(huì)遇到的坑

• 如果訪問不了云上user類的內(nèi)容,很可能是user類的一些權(quán)限沒打開(默認(rèn)是每個(gè)用戶需要登錄才能使用),去官網(wǎng)項(xiàng)目中暫時(shí)開啟權(quán)限,方便調(diào)試.
• 如果user類無法注冊(cè)新用戶,而官網(wǎng)的測試API卻可以,很可能是官網(wǎng)項(xiàng)目中->云開發(fā)->云設(shè)置 開啟注冊(cè)用戶郵箱驗(yàn)證,關(guān)閉它.
• AppID和AppKey記錄在官網(wǎng)項(xiàng)目->概覽->項(xiàng)目圖標(biāo)下拉按鈕里頭
