我正在开发Android应用程序并将多部分表单数据HTTP POST发送到我的IIS服务器。我需要查看我的服务器正在接收的原始HTTP消息。为此，在visual studio 2013中，我在此行之后放置了一个中断
public String Report([Bind(Include = "lasfotos,comentario,asunto")] HttpPostedFileBase lasfotos, string comentario, string asunto)
在局部变量中，我可以在此＆gt; base＆gt;请求中查看有关http消息的大量信息，例如路径，内容长度等，但我无法找到原始HTTP的位置。
编辑：为什么我认为看到原始http是一个解决方案？因为我觉得我很容易在这里找到问题。但我会告诉你我的基本问题： 我在java中有这个函数，它将数据发送到服务器。我可以看到我的变量值（在服务器中）＆＃34; comentario＆＃34;和＆＃34; asunto＆＃34;但是＆＃34; lasfotos＆＃34; = null
public static String Postear(ArrayList<File> files, String asunto, String detalle)
{
String respuesta;
try
{
String boundary = "qu1ckr3port_myb0undy";
String filesboundary = "boundy_4_files";
URL url = new URL("http://192.168.10.100/QuickReport/Uploads/Report");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
DataOutputStream outputStream = new DataOutputStream(connection.getOutputStream());
outputStream.writeBytes("--"+boundary+"\r\n" +
"Content-Disposition: form-data; name=\"lasfotos\"\r\n" +
"Content-Type: multipart/mixed; boundary="+filesboundary+"\r\n\r\n");
for (byte i = 0; i < files.size(); i++)
{
outputStream.writeBytes("--"+filesboundary+"\r\n" +
"Content-Disposition: file; filename=\"" + files.get(i).getName() + "\"\r\n" +
"Content-Type: image/jpeg\r\n\r\n");
FileInputStream fileInputStream = new FileInputStream(files.get(i));
int bytesAvailable = fileInputStream.available();
int bufferSize = Math.min(bytesAvailable, 1024 * 1024);
byte[] buffer = new byte[bufferSize];
int bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, 1024 * 1024);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
fileInputStream.close();
outputStream.writeBytes("\r\n");
}
outputStream.writeBytes("--"+filesboundary+"--\r\n" +

"Content-Disposition: form-data; name=\"comentario\"\r\n\r\n" +

String linea;
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

reader.close();
outputStream.flush();

答案 0 :(得分：0)
我认为问题是文档不好。我遵循了本页http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
中记录的格式Content-Type: multipart/form-data; boundary=AaB03x
--AaB03x
Content-Disposition: form-data; name="submit-name"
Larry
--AaB03x
Content-Disposition: form-data; name="files"
Content-Type: multipart/mixed; boundary=BbC04y
--BbC04y
Content-Disposition: file; filename="file1.txt"
Content-Type: text/plain
... contents of file1.txt ...
--BbC04y
Content-Disposition: file; filename="file2.gif"
Content-Type: image/gif
Content-Transfer-Encoding: binary
...contents of file2.gif...
--BbC04y--
--AaB03x--
这就是问题所在。我只是改变了我的代码，现在工作得很好。这是我的新代码：
public static String Postear(ArrayList<File> files, String asunto, String detalle)
{
String respuesta;
try
{
String boundary = "qu1ckr3port_myb0undy";
URL url = new URL("http://192.168.10.100/QuickReport/Uploads/Report");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
DataOutputStream outputStream = new DataOutputStream(connection.getOutputStream());
for (byte i = 0; i < files.size(); i++)
{
outputStream.writeBytes("--"+boundary+"\r\n" +
"Content-Disposition: form-data; name=\"lasfotos\" filename=\"" + files.get(i).getName() + "\"\r\n" +
"Content-Type: image/jpeg\r\n\r\n");
FileInputStream fileInputStream = new FileInputStream(files.get(i));
int bytesAvailable = fileInputStream.available();
int bufferSize = Math.min(bytesAvailable, 1024 * 1024);
byte[] buffer = new byte[bufferSize];
int bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, 1024 * 1024);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
fileInputStream.close();
outputStream.writeBytes("\r\n");
}
outputStream.writeBytes("--"+boundary+"\r\n" +
"Content-Disposition: form-data; name=\"comentario\"\r\n\r\n" +
detalle + "\r\n");
outputStream.writeBytes("\r\n" +
"--"+boundary+"\r\n" +
"Content-Disposition: form-data; name=\"asunto\"\r\n\r\n" +
asunto + "\r\n" +
"--"+boundary+"--\r\n");
respuesta = "";
String linea;
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while ((linea = reader.readLine()) != null) respuesta += linea;
reader.close();
outputStream.flush();
outputStream.close();
} catch (Exception e)
{
respuesta = "error";
e.printStackTrace();
}
return respuesta;
}
希望这对某人有用......
