其實呢,Bmob官方文件已經非常完善了,只是...還是在使用的過程中還是會遇到問題的~

以後整Demo都想用這個,所以記錄一下遇到的問題~

一.建表,增加檔案列,上傳檔案

首先建立表,增加檔案列

 上傳檔案 :

 二.查詢並下載

unity中建立對應資料類(注意,名字一定要與列的名字保持一致,因為這個錯誤,卡了好久) :

public class BmobData : BmobTable {
    //名字保持一致
    public BmobFile File { get; set; }
    public override void readFields(BmobInput input)
    {
        base.readFields(input);
        this.File = input.Get<BmobFile>("File");
    }

    public override void write(BmobOutput output, bool all)
    {
        base.write(output, all);

        output.Put("File", this.File);
    }
}
 

得到地址:

public class BmobQueryS : MonoBehaviour {
    public BmobUnity bmobUnity;
    BmobQuery query = new BmobQuery();
    public string TABLENAME = "Resource";
    public bool isGetAll = false;
    public Dictionary<string, string> typeToURL = new Dictionary<string, string>();
    public List<String> Type = new List<String>();
    public void Awake()
    {
        QueryFile();
    }
    public void QueryFile()
    {
        bmobUnity.Find<BmobData>(TABLENAME, query, (resp, exception) =>
        {
            if (exception != null)
            {
                print("查詢失敗, 失敗原因為： " + exception.Message);
                return;
            }

            //對返回結果進行處理
            List<BmobData> list = resp.results;
            foreach (BmobData bmobData in list)
            {
                typeToURL.Add(bmobData.File.filename, bmobData.File.url);
                Debug.Log(bmobData.File.filename + " " + bmobData.File.getPath());
            }
            isGetAll = true;
            foreach (string type in TypeAndFunc.Keys)
            {
                StartCoroutine(DownTool._Instance.LoadHotFixAssembly(type, typeToURL[type]);
            }
        });
    }
    public void IsGetAll(string type)
    {
        if (isGetAll)
        {
            StartCoroutine(DownTool._Instance.LoadHotFixAssembly(type,typeToURL[type]));
        }
        else
        {
            Type.Add(type);
        }
    }
}
 

下載並儲存:

public class DownTool {
    static DownTool instance;
    public static DownTool _Instance
    {
        get
        {
            if (instance == null)
                instance = new DownTool();
            return instance;
        }
    }

    public IEnumerator LoadHotFixAssembly(string filename,string uri)
    {
        UnityWebRequest request = UnityWebRequest.Get(uri);
        yield return request.SendWebRequest();
        CreatFile(Application.persistentDataPath,filename, request.downloadHandler.data);
    }
    public void CreatFile(string savePath, string name, byte[] content)
    {
        string filePath = savePath + "/" + name;
        if (File.Exists(filePath))
        {
            File.Delete(filePath);
        }
        Stream sw;
        FileInfo fileInfo = new FileInfo(filePath);
        sw = fileInfo.Create();
        sw.Write(content, 0, content.Length);
        sw.Close();
        sw.Dispose();
        Debug.Log("儲存檔案路徑:" + filePath);
    }
}
