delphi – Indy在每72个字符处添加=多部分表单数据Post

使用Delphi XE和Indy,我得到了一些提交到Web表单的代码.

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？

你看到的是正确的行为. TIdFormDataField.ContentTransfer属性默认为文本字段的quoted-printable.这正是您所看到的编码类型.在quoted-printable中,sole =字符后跟换行符称为“软”断点.这就是MIME如何分解长行文本以适应各种协议(如电子邮件)中的行长度限制.

您可以将ContentTransfer属性更改为以下任何受支持的值：

>一个空白字符串
> 7bit
> 8位
>二进制
>引用可打印
> base64

如果您不希望对文本进行编码,请将ContentTransfer属性设置为quoted-printable或base64以外的任何值.
