Question

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;

然而，当我在描述备忘录中输入类似的东西时。

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.

我得到了

This is a really long descriptie piece of text so we can see just how =

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？

Answer 1

你看到的是正确的行为。对于文本字段，TIdFormDataField.ContentTransfer属性默认为quoted-printable。这正是您所看到的编码类型。在quoted-printable中，后跟换行符的唯一=字符称为“软”中断。这就是MIME如何分解长行文本以适应各种协议（例如电子邮件）中的行长度限制。

您可以将ContentTransfer属性更改为以下任何支持的值：

空白字符串
7bit
8bit
binary
quoted-printable
base64

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

Answer 2

它将这些内容编码为引用可打印的内容。您需要在显示它之前对其进行解码。
