重新启动PC后，后台服务可以正常工作。如果我重新安装数据库或对数据库进行了任何更改，则我的PC访问路径“ .zip”被拒绝。同一背景在另一台PC上运行的另一件事。
在两个不同的PC上运行的两个后台服务可以交换数据。
代码如下：
public void GetFilesFromWebAPIAndCountTemplates(DateTime startTime,DateTime endTime,string webAPIURL,string code,string localPath)
{
ZipLocationsCount zipLocation = null;
count = 0;
if (startTime < endTime)
{
WebApiCall apiCall = new WebApiCall();
Thread.Sleep(10000);
var zipByteResponse = apiCall.CallZipWebApi(webAPIURL, "api/ZIPEnrollmentsDownload/ZIPResponse?startTime=" + startTime + "&endTime=" + endTime+ "&locationCode="+code, null, Constants.Get);
lgmr.Log(string.Concat(serviceName, " ", code, ": Get Response From WebAPI successfully"), LoggingManager.LogType.Info);
if (zipByteResponse.Result != null && zipByteResponse.Result.Length > 0)
{
string fileName = code + "_Enrollments.zip";
try
{
ConvertIntoZipAndMoveToBackUp(localPath, fileName, zipByteResponse.Result, code);
}
catch(Exception ex)
{
//GetFilesFromWebAPIAndCountTemplates(startTime, endTime, webAPIURL, code, localPath);
ecount = 0;
strECount = "Fail to Zip";
lgmr.Log(string.Concat(serviceName, " ", code, " count:", ecount, ": Failed to Converted to ZIP", ex.StackTrace, ex.InnerException, ex.Message), LoggingManager.LogType.Error);
goto label1;
}
}
else
{
ecount = 0;
if(ecount == 0)
{
strECount = "No Enrolments";
}
lgmr.Log(string.Concat(serviceName, " ", code, ": No Enrollments"), LoggingManager.LogType.Info);
}
}
else
{
lgmr.Log(string.Concat(serviceName, " ",code, ": Start Date Should be lass than End Date"), LoggingManager.LogType.Info);
}
FPSyncHistory fpSync = new FPSyncHistory();
fpSync.LocationCode = code;
fpSync.FromDate = startTime;
fpSync.ToDate = endTime;
fpSync.FPExported = ecount;
fpSync.Status = true;
fpSync.CreatedBy = 1;
fpSync.CreatedOn = DateTime.Now;
fPSyncHistories.Add(fpSync);
label1:
zipLocation = new ZipLocationsCount() { LocationCode = code, FromDate = startTime, ToDate = endTime, EnrollmentsCount = strECount };
if (zipLocation.FromDate < zipLocation.ToDate)
{
zipLocationsCounts.Add(zipLocation);
}
}
我正在调用上述方法
public void GetZipResponseFromWebAPI()
{
try
{
zipLocationsCounts = new List<ZipLocationsCount>();
fPSyncHistories = new List<FPSyncHistory>();
DateTime sTime = new DateTime();
DateTime startTime = new DateTime();
DateTime eTime = new DateTime();
DateTime endTime = new DateTime();
foreach (FPSyncLocationDetail fpLocation in tmlEntity.FPSyncLocationDetails)
{
var findHistory = tmlEntity.FPSyncHistories.FirstOrDefault(x => x.LocationCode == fpLocation.Code);
if (findHistory == null)
{
if(fpLocation.Status == true)
{
sTime = DateTime.Now.AddDays(-1);
startTime = new DateTime(sTime.Year, sTime.Month, sTime.Day, 00, 00, 00);
eTime = DateTime.Now.AddDays(-1);
endTime = new DateTime(eTime.Year, eTime.Month, eTime.Day, 23, 59, 59);
GetFilesFromWebAPIAndCountTemplates(startTime,endTime,fpLocation.WebAPIURL,fpLocation.Code,fpLocation.LocalFPFolderPath);
}
}
else if (findHistory != null)
{
var locationLastDates = from n in tmlEntity.FPSyncHistories
group n by n.LocationCode into g
select new { LocationCode = g.Key, ToDate = g.Max(t => t.ToDate) };
foreach (var loc in locationLastDates)
{
if (fpLocation.Code == loc.LocationCode)
{
if (fpLocation.Status == true)
{
sTime = loc.ToDate.AddDays(1);
startTime = new DateTime(sTime.Year, sTime.Month, sTime.Day, 00, 00, 00);
eTime = DateTime.Now.AddDays(-1);
endTime = new DateTime(eTime.Year, eTime.Month, eTime.Day, 23, 59, 59);
GetFilesFromWebAPIAndCountTemplates(startTime, endTime, fpLocation.WebAPIURL, fpLocation.Code, fpLocation.LocalFPFolderPath);
}
}
}
}
}
}
catch (Exception ex)
{
string InnerException = ex.InnerException != null ? ex.InnerException.ToString() : "";
lgmr.Log(string.Concat("Error at GetZipResponseFromWebAPI", ex.StackTrace, ex.InnerException, ex.Message), LoggingManager.LogType.Error);
return;
}
}
最终在下面使用CallWebAPI方法逻辑
public async Task<byte[]> CallZipWebApi(String WebApiUri, String uri, StringContent obj, string type)
{
try
{
count++;
HttpResponseMessage resMeg;
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));
client.BaseAddress = new Uri(WebApiUri);
lgmr.Log(string.Concat(uri,": Sending Request to WebAPI"), LoggingManager.LogType.Info);
if (type == Constants.Get)
{
resMeg =await client.GetAsync(uri);
}
else
{
resMeg =await client.PostAsync(uri, obj);
}
lgmr.Log(string.Concat(uri,": Receive Response From WebAPI"), LoggingManager.LogType.Info);
var Bytes =await resMeg.Content.ReadAsByteArrayAsync();
//byte[] mybyteArray = null;
//Task<byte[]> Bytes = ProcessURLAsync(uri,client);
lgmr.Log(string.Concat(": Read the Data from WebAPI Response"), LoggingManager.LogType.Info);
return Bytes;
}
}
}
public void ConvertIntoZipAndMoveToBackUp(string localPath, string fileName, byte[] zipByteResponse, string code)
{
string Destinationpath = ConfigurationManager.AppSettings["OtherEnrollmentsBackUpPath"] + "\\" + code;
try
{
ZipArchive archive = null;
if (File.Exists(localPath + "\\" + fileName))
{
File.Delete(localPath + "\\" + fileName);
}
archive = ZipFile.Open(localPath + "\\" + fileName, ZipArchiveMode.Create);
archive.Dispose();
lgmr.Log(string.Concat(serviceName, " ", code, ": Zip File Created", localPath + "\\" + fileName), LoggingManager.LogType.Info);
File.WriteAllBytes(localPath + "\\" + fileName, zipByteResponse);
lgmr.Log(string.Concat(serviceName, " ", code, ": Download Zipfile from the WebAPI Response"), LoggingManager.LogType.Info);
archive = ZipFile.OpenRead(localPath + "\\" + fileName);
ecount = archive.Entries.Count(x => !string.IsNullOrWhiteSpace(x.Name));
strECount = ecount.ToString();
lgmr.Log(string.Concat(serviceName, " ", code, ": Files Count: ",ecount, localPath + "\\" + fileName), LoggingManager.LogType.Info);
foreach (ZipArchiveEntry entry in archive.Entries)
{
if (File.Exists(localPath + "\\" + entry.Name))
{
File.Delete(localPath + "\\" + entry.Name);
}
entry.ExtractToFile(localPath + "\\" + entry.Name);
}
archive.Dispose();
File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("Enrollments-{0:yyyy-MM-dd_hh-mm-ss.fff}.zip", DateTime.Now));
}
catch (Exception ex)
{
//File.Delete(localPath + "\\" + fileName);
//File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("ZipErrorEnrollments-{0:yyyy-MM-dd_hh-mm-ss.fff}.zip", DateTime.Now));
ecount = 0;
lgmr.Log(string.Concat(serviceName, " ", code, " ECount:", ecount, ": Failed to ZIP", localPath + "\\" + fileName, "Resend the Request to WebAPI ", ex.Message), LoggingManager.LogType.Info);
throw ex;
}
}
答案 0 :(得分：1)
您可以看的几件事。
首先，使用using语句创建档案，以确保将其处置。
第二，为什么要检查文件是否存在，删除它，然后用ZipFile创建它，而只是用File来写？看this
第三，使用Path类。它将确保您所有的反斜杠都是正确的，并且看起来更整洁。
第四，检查是否可以在文件夹中创建文件
检查此代码是否给您相同的结果。
public void ConvertIntoZipAndMoveToBackUp(string localPath, string fileName, byte[] zipByteResponse, string code)
{
string Destinationpath = Path.Combine(ConfigurationManager.AppSettings["OtherEnrollmentsBackUpPath"], code);
try
{
fileName = Path.GetFileNameWithoutExtension(fileName) + DateTime.Now.ToString("yyyy-MM-dd_hh-mm-ss.fff") + ".zip"; //This will ensure that you have a unique filename to create
File.WriteAllBytes(Path.Combine(localPath, fileName), zipByteResponse);
lgmr.Log(string.Concat(serviceName, " ", code, ": Zip File Created and Downloaded from the WebAPI Response", Path.Combine(localPath, fileName)), LoggingManager.LogType.Info);
using (var archive = ZipFile.OpenRead(Path.Combine(localPath, fileName)))
{
ecount = archive.Entries.Count(x => !string.IsNullOrWhiteSpace(x.Name));
strECount = ecount.ToString();
lgmr.Log(string.Concat(serviceName, " ", code, ": Files Count: ",ecount, localPath + "\\" + fileName), LoggingManager.LogType.Info);
foreach (ZipArchiveEntry entry in archive.Entries)
{
if (File.Exists(Path.Combine(localPath, entry.Name)))
{
File.Delete(Path.Combine(localPath, entry.Name));
}
entry.ExtractToFile(Path.Combine(localPath, entry.Name));
}
}
File.Move(Path.Combine(localPath, fileName), Path.Combine(Destinationpath, code + string.Format("Enrollments-{0:yyyy-MM-dd_hh-mm-ss.fff}.zip", DateTime.Now)));
}
catch (Exception ex)
{
//File.Delete(localPath + "\\" + fileName);
//File.Move(localPath + "\\" + fileName, Destinationpath + "\\" + code + string.Format("ZipErrorEnrollments-{0:yyyy-MM-dd_hh-mm-ss.fff}.zip", DateTime.Now));
ecount = 0;
lgmr.Log(string.Concat(serviceName, " ", code, " ECount:", ecount, ": Failed to ZIP", localPath + "\\" + fileName, "Resend the Request to WebAPI ", ex.Message), LoggingManager.LogType.Info);
throw ex;
}
