The following is the code for the JAVA calls:
Public void doUploadFile () throws the Exception
{
The String file="E:/044160004044 JPG";
String bh="430600100063";
String sj="2017-09-02 11:07:23";
ByteArrayOutputStream bos=new ByteArrayOutputStream ();
BufferedInputStream bis=new BufferedInputStream (new FileInputStream (file));
Int len.
While ((len=bis. Read ()) & gt; 1) {bos. Write (len); }
Byte fileData []=bos. ToByteArray ();
Int tpsize1=fileData. Length;
String urlstr="HTTP://http://127.0.0.1:8080/uploadFile.tfc? Method=savePicture& Bh="+ bh.
Urlstr +="& amp; Sj="+ sj.
URL the URL=new URL (urlstr);
HttpURLConnection huc=(HttpURLConnection) url. OpenConnection ();
Huc. SetRequestProperty (" the content-type ", "text/HTML");
Huc. SetRequestProperty (" the content-type ", "application/x - WWW - form - urlencoded; charset=utf-8");
Huc. SetDoOutput (true);
Huc. SetDoInput (true);
Huc. SetRequestMethod (" POST ");
Huc. SetConnectTimeout (500000);
OutputStream pw=huc. GetOutputStream ();
Pw. Write (fileData);
Pw. Flush ();
pw.close();
BufferedReader br=new BufferedReader (new InputStreamReader (huc. GetInputStream ()));
The String content="";
The String line=br. ReadLine ();
While (the line!=null)
{
The content=content + line;
The line=br. ReadLine ();
}
br.close();
}


How do the above code written in Delphi, I use Idhttp controls, picture is the copy of transfer will not come!

refer to the second floor lyhoo163 response:

inflow in the MS image file to read, but did not see will upload code, MS

Oneself to find some information, didn't understand to upload pictures that block:
//to connect to the URL
