与GridJs服务器端配合工作

0. 在配置中设置正确的文件夹路径

Config.FileCacheDirectory 用于工作簿缓存文件。 Config.PictureCacheDirectory 用于工作簿中的图像文件缓存。

有关存储详细信息，请参阅此指南

1. 实现 GridCacheForStream

对于本地文件存储，这里有一个示例：

对于服务器端存储，我们也提供了一个示例。 Please check: https://github.com/aspose-cells/Aspose.Cells-for-.NET/blob/master/Examples_GridJs/Models/AwsCache.cs

2. 从电子表格文件中获取JSON。

GridJsWorkbook wbj = new GridJsWorkbook();
using (FileStream fs = new FileStream(path, FileMode.Open))
{
    wbj.ImportExcelFile(fs,GridJsWorkbook.GetGridLoadFormat(Path.GetExtension(path)));
}
String ret =wbj.ExportToJson();

3. 从电子表格文件中获取图像/形状

//Gridjs will automatically zip all the images/shapes into a zip stream  and store it in cache using the cache implemention.
//GridJsWorkbook.CacheImp.SaveStream(zipoutStream, fileid);

//get the fileid in the cache,uid is the unique id for the spreadsheet  instance, sheetid is the sheet index,
String fileid=(uniqueid + "." + (sheetid + '_batch.zip'))

//get the zip file stream by the fileid
Stream s=GridJsWorkbook.CacheImp.LoadStream(fileid), mimeType, fileid.Replace('/', '.')

4. 在缓存中更新电子表格文件

GridJsWorkbook gwb = new GridJsWorkbook();
//p is the update json,uid is the unique id for the spreadsheet
String ret = gwb.UpdateCell(p, uid);

5. 将电子表格文件保存在缓存中

GridJsWorkbook wb = new GridJsWorkbook();
//p is the update json,uid is the unique id for the spreadsheet
wb.MergeExcelFileFromJson(uid, p);
wb.SaveToCacheWithFileName(uid, filename,password);
