我需要将
Windows Phone 7中的图像发送到某些电子邮件地址.
我使用这个类将文本值提交给 PHP脚本,解析数据并将格式化的电子邮件发送到地址.
问题是我无法弄清楚如何将图像发送到该脚本,将图像附加到电子邮件.可以以任何方式更改PHP脚本.如果我有一个Image对象,如何更改此类以允许发送图像？

public class PostSubmitter
{
public string url { get; set; }
public Dictionary<string,string> parameters { get; set; }
public PostSubmitter() { }
public void Submit()
{
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback),myRequest);
}
private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
System.IO.Stream postStream = request.EndGetRequestStream(asynchronousResult);
// Prepare Parameters String
string parameteRSString = "";
foreach (keyvaluePair<string,string> parameter in parameters)
{
parameteRSString = parameteRSString + (parameteRSString != "" ? "&" : "") + string.Format("{0}={1}",parameter.Key,parameter.Value);
}
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(parameteRSString);
// Write to the request stream.
postStream.Write(byteArray,parameteRSString.Length);
postStream.Close();
// Start the asynchronous operation to get the response
request.BeginGetResponse(new AsyncCallback(GetResponseCallback),request);
}
private void GetResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
string responseString = streamRead.ReadToEnd();
// Close the stream object
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse
response.Close();
//Action<string> act = new Action<string>(displayResponse);
//this.dispatcher.BeginInvoke(act,responseString);
}
我用这种方式使用这个类：
Dictionary<string,string> data = new Dictionary<string,string>()
{
{"nom",nom.Text},{"cognoms",cognoms.Text},{"email",email.Text},{"telefon",telefon.Text}
};
PostSubmitter post = new PostSubmitter() { url = "http://example.com/parserscript.PHP",parameters = data };
post.Submit();
非常感谢你！
我已将上面的代码转换为以下代码,我相信它会有所帮助：
public class PostSubmitter
{
public string url { get; set; }
public Dictionary<string,object> parameters { get; set; }
string boundary = "----------" + DateTime.Now.Ticks.ToString();
public PostSubmitter() { }
public void Submit()
{
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(new Uri(url));
myRequest.Method = "POST";
myRequest.ContentType = string.Format("multipart/form-data; boundary={0}",boundary);
myRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback),myRequest);
}
private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
Stream postStream = request.EndGetRequestStream(asynchronousResult);
writeMultipartObject(postStream,parameters);
postStream.Close();
request.BeginGetResponse(new AsyncCallback(GetResponseCallback),request);
}
private void GetResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse
response.Close();
}
public void writeMultipartObject(Stream stream,object data)
{
StreamWriter writer = new StreamWriter(stream);
if (data != null)
{
foreach (var entry in data as Dictionary<string,object>)
{
WriteEntry(writer,entry.Key,entry.Value);
}
}
writer.Write("--");
writer.Write(boundary);
writer.WriteLine("--");
writer.Flush();
}
private void WriteEntry(StreamWriter writer,string key,object value)
{
if (value != null)
{
writer.Write("--");
writer.WriteLine(boundary);
if (value is byte[])
{
byte[] ba = value as byte[];
writer.WriteLine(@"Content-disposition: form-data; name=""{0}""; filename=""{1}""",key,"sentPhoto.jpg");
writer.WriteLine(@"Content-Type: application/octet-stream");
//writer.WriteLine(@"Content-Type: image / jpeg");
writer.WriteLine(@"Content-Length: " + ba.Length);
writer.WriteLine();
writer.Flush();
Stream output = writer.BaseStream;
output.Write(ba,ba.Length);
output.Flush();
writer.WriteLine();
}
else
{
writer.WriteLine(@"Content-disposition: form-data; name=""{0}""",key);
writer.WriteLine();
writer.WriteLine(value.ToString());
}
}
}
}
要将图像从相机转换为字节数组,我已经使用了以下内容：
private void photochooserTask_Completed(object sender,PhotoResult e)
{
try
{
BitmapImage image = new BitmapImage();
image.SetSource(e.ChosenPhoto);
foto.source = image;
using (MemoryStream ms = new MemoryStream())
{
WriteableBitmap btmMap = new WriteableBitmap(image);
// write an image into the stream
Extensions.SaveJpeg(btmMap,ms,image.PixelWidth,image.PixelHeight,100);
byteArray = ms.ToArray();
}
}
catch (ArgumentNullException) { /* nothing */ }
}
我这样使用这个类：
Dictionary<string,object> data = new Dictionary<string,object>()
{
{"nom",telefon.Text},{"comentari",comentari.Text},{"foto",byteArray},};
PostSubmitter post = new PostSubmitter() { url = "http://example.com/parserscript.PHP",parameters = data};
post.Submit();
我不知道这是将图像从手机发送到服务器的最佳方式,但是我找不到任何东西,所以我自己上课只是读这个,而且这花了我好几天.如果有人想改进代码或写任何评论将受到欢迎.
