content-length

[Robert Kennedy]

I am trying to determine the content-length for a post.

Is this correct?

  
 
private static final String strB= "---------------------------7d22c61f5b8";
private static final String strBLF = "-----------------------------7d22c61f5b8\r\n";
private static final String strBLD = "\r\n-----------------------------7d22c61f5b8\r\n";
 

StringBuffer sbFileParameters = (new StringBuffer())
.append("Content-Disposition: form-data; name=\""+file.getName()+"\"; filename=\"" + file.getCanonicalPath() + "\"\r\n")
.append("Content-Type: image/pjpeg\r\n\r\n");
 
StringBuffer sbHeaderParameters = (new StringBuffer(strB))
.append(constructParam ("file_sep",File.separator))
.append(constructParam ("userid",strUserId));
 

StringBuffer sbHttpHeader =(new StringBuffer("POST "))
.append(uUrl.getFile())
.append(" HTTP/1.1\r\n")
.append("Content-Type: multipart/form-data, boundary=\"")
.append(strB)
.append("\"\r\nCache-Control: no-cache\r\n")
.append("Pragma: no-cache\r\n")
.append("User-Agent: Mozilla/4.0 (Windows XP 5.1) Java/1.5.0_06\r\n")
.append("Host: " + uUrl.getHost() + "\r\n")
.append("Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2\r\n")
.append("Connection: keep-alive\r\n")
.append("Content-Length: ")
.append(getContentLength(sbFileParameters, sbHeaderParameters))
.append("\r\n");
 

 

// write to socket
write(sbHttpHeader);
write(sbHeaderParameters);
write(sbFileParameters);
while ( ((bytesReadIn = fis.read(buffer)) != -1) ) 
   write(buffer, 0, bytesReadIn);
write(strBLD);
 
......
 

private long getContentLength(StringBuffer sbFileParams, StringBuffer sbHeaderParams) {
long len=0;
len += sbHeaderParams.toString().getBytes().length;
len += sbFileParams.toString().getBytes().length;
len += file.length();
len +=strBLD.getBytes().length;
return len;
}
