Question

我正在尝试构建一个以pdf格式发送电子邮件的功能，我需要从其他服务器读取文件，然后将其附加到电子邮件中。

我已经用txt测试了它，并且可以正常工作，但是当我使用pdf时，它会附加一个无法打开的文件。

到目前为止，这是我的代码：

let dados = {
    "para": "::EMAIL::",
    "body": "Olá",
    "assunto": "Teste",
    "from": "::EMAIL::",
    "anexo": "teste.pdf" // Name of the file I want to read from server
};

request.get("::URL_SERVER::" + dados.anexo, function (error, response, body) {
    let anexo;

    if (!error && response.statusCode == 200) {
        anexo = body;
    }

    let ses_mail =
`From: 'AWS SES Attchament Configuration' <${dados.from}>
To: <${dados.para}>
Subject: ${dados.assunto}
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="NextPart"

--NextPart
Content-Type: text/html

${dados.body}

--NextPart
Content-Type: application/pdf; name="${dados.anexo}"
Content-Transfer-Encoding: base64
Content-Disposition:attachment

${anexo.toString("base64").replace(/([^\0]{76})/g, "$1\n")}

--NextPart`;

    let params = {
        RawMessage: {Data: ses_mail},
        Source: `'AWS SES Attchament Configuration' <${dados.from}>`
    };

    let sendPromise = new AWS.SES({apiVersion: '2010-12-01'}).sendRawEmail(params).promise();

    return sendPromise.then(
        data => {
            console.log(data);
            return data;
        }).catch(
        err => {
            console.error(err.message);
            throw err;
        });
});

可以用axios做到吗？我只在我的研究中找到了如何下载文件

我可以做到，但是我需要更改用于同步请求的库。我的最终代码：

let anexo = null;

        try {
            anexo = request( "GET", "::URL::" + dados.anexo );
        } catch (err) {
            console.error(err, err.stack);
            return criarResposta( 404, 'Anexo não encontrado' );
        }

        anexo = anexo.getBody();

        //return criarResposta( 200, anexo.toString("base64") );

        let ses_mail =
`From: 'AWS SES Attchament Configuration' <${dados.from}>
To: <${dados.para}>
Subject: ${dados.assunto}
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="NextPart"

--NextPart
Content-Type: text/html

${dados.body}

--NextPart
Content-Type: application/octet; name="arquivo.pdf"
Content-Transfer-Encoding: base64
Content-Disposition:attachment

${anexo.toString("base64")}

--NextPart`;

        let params = {
            RawMessage: {Data: ses_mail},
            Source: `'AWS SES Attchament Configuration' <${dados.from}>`
        };

        sendPromise = new AWS.SES({apiVersion: '2010-12-01'}).sendRawEmail(params).promise();

        try {
            const data = await sendPromise;
            console.log(data.MessageId);
            return criarResposta( 200, 'OK' );
        } catch (err) {
            console.error(err, err.stack);
            return criarResposta( 500, 'Erro interno' );
        }

我无法使用Amazon SDK JS发送带有pdf的电子邮件，但是发送txt可以正常工作吗？
