delphi – Indy在每72个字符处添加=多部分表单数据Post

idhttp := TidHttp.create;
postData := TIdMultiPartFormDataStream.Create;
try
    postData.AddFormField('name',edName.text);
    postData.AddFormField('email',edEmail.txt);
    postData.AddFormField('description',mDescription.text);

    idhttp.Request.ContentType := 'Content-Type: multipart/form-data; boundary=' + postData.Boundary;
    idhttp.fHttp.Post('http://www.example.com/contact.php',postData);

    ShowMessage('Thank you for your contact us.');
finally
    postData.Free;
    idHttp.Free;
end;

但是,当我在描述备忘录中输入类似的内容时.

This is a really long descriptie piece of text so we can see just how it's wrapping these lines and what it's doig to them I think it's making a hash of it.

Argh waht a pain.

我明白了

This is a really long descriptie piece of text so we can see just how =
it's wrapping these lines and what it's doig to them I think it's maki=
ng a hash of it.

Argh waht a pain.

所以对我来说似乎是自动换行,=
有线索的人吗？
