Delphi使用TNetHTTPClient上传文件java接收测试
上传客户端
新建一个应用，拖入一个TButton按扭，一个TMemo多行文件显示框，一个TNetHttpClient,一个OpenDialog文件打开对话框。
双击按扭添加代码
uses System.Net.Mime ;
procedure TForm1.Button1Click(Sender: TObject);
var
formData: TMultipartFormData;
AResponseContent: TStringStream;
begin
if OpenDialog1.Execute then
begin
formData := TMultipartFormData.Create;
AResponseContent := TStringStream.Create('', TEncoding.GetEncoding(65001));
try
formData.AddFile('file1', OpenDialog1.FileName);
with self.NetHTTPClient1 do
begin
ConnectionTimeout := 2000;
ResponseTimeout := 10000;
AcceptCharSet := 'utf-8';
AcceptEncoding := '65001';
AcceptLanguage := 'zh-CN';
ContentType := 'multipart/form-data';
UserAgent := 'Embarcadero URI Client/1.0';
try
Memo1.Lines.Add('上传文件 ' + OpenDialog1.FileName);
Post('http://localhost:9001/filesrv/file/upload', formData, AResponseContent);
Application.ProcessMessages;
except
on E: Exception do
Memo1.Lines.Add('上传失败:' + E.Message);
end;
Memo1.Lines.Add(AResponseContent.DataString);
end;
finally
AResponseContent.Free;
formData.Free;
end;
end;
end;java接收端
