我尝试将图像从我的 WCF 服务上传到 Amazon S3 Web 服务器。我有在 Web 项目中工作的 Amazon S3 代码和在 WCF 服务中的 Uploded\test.jpg 中上传图像的图像上传方法。我不确定如何将 Amazon S3 代码与 WCF 服务一起使用。第一,当我在未上传的情况下添加这些代码行时,我不知道如何将亚马逊凭证放入网络配置中:
<appSettings>
<add key="AWSAccessKey" value="myaccessKey"/>
<add key="AWSSecretKey" value="MySecretKey"/>
</appSettings>
这是我上传到 WCF 服务器的方法我想当我在这里说 //AWS 时我必须添加 AWS 代码:
[WebInvoke(UriTemplate = "UploadImage", Method = "POST")]
Stream UploadImage(Stream request)
{
Stream requestTest = request;
StreamWriter sw = null;
string logpath = HttpContext.Current.Server.MapPath("Uploded\\logtest.txt");
logpath = logpath.Replace("SSGTrnService\\", "");
HttpMultipartParser parser = new HttpMultipartParser(request, "file");
string filePath = "";
string passed = parser._content;
string sLogFormat = DateTime.Now.ToShortDateString().ToString() + " " + DateTime.Now.ToLongTimeString().ToString() + " ==> ";
sw = new StreamWriter(logpath);
sw.Flush();
if (parser.Success)
{
// Save the file somewhere
//File.WriteAllBytes(FILE_PATH + title + FILE_EXT, parser.FileContents);
// Save the file
//SaveFile( mtp.Filename, mtp.ContentType, mtp.FileContents);
FileStream fileStream = null;
BinaryWriter writer = null;
try
{
filePath = HttpContext.Current.Server.MapPath("Uploded\\test.jpg"); // BuildFilePath(strFileName, true);
filePath = filePath.Replace("SSGTrnService\\", "");
fileStream = new FileStream(filePath, FileMode.Create);
fileStream.Write(parser.FileContents, 0, parser.FileContents.Length);
// return filePath;
}
catch (Exception ex)
{
return "Error: " + ex.Message;
}
finally
{
if (fileStream != null)
fileStream.Close();
if (writer != null)
writer.Close();
//AWS Code
}
}
//
// returning text for html DOM
//
string text = "Image uploaded: " + parser.Filename + " / " + parser.ContentType + filePath + passed;
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
MemoryStream ms = new MemoryStream(encoding.GetBytes(text));
WebOperationContext.Current.OutgoingResponse.ContentType = "text/html";
return ms;
}
从 WCF 服务调用 Amazon S3 的任何指南都会很棒。
