Emaiing pdf not working

[Doghousedev]

I am trying to attach a pdf (quote.pdf) to JSON body being sent to the mail server.

I am getting a corrupted pdf being sent.

The pdf renders on screen in the viewer properly. If I manually encode the saved rendered report (pdf) as Base64 , hard code it in the JSON message base64Content and send it to the mail server, it attaches correctly.

However, when I try to encode the quote programmatically, I am getting a corrupted pdf. Console Logging the base64data output and comparing it to the same report base64 are different.

I have an onEmailReport which calls sendMail function

Code: Select all

viewer.onEmailReport = () => sendEmail(viewer);

async function sendEmail(viewer) {

  const report = viewer.report

  console.log(report)

  // Export report as PDF 
  const pdf = report.exportDocument(Stimulsoft.Report.StiExportFormat.Pdf);

  // Convert to Base64 string
  const base64data = btoa(pdf)
  console.log(base64data );

  const data = {
    "Messages": [
      {
        "From": {
          "Email": "ron@demomail.com",
          "Name": "Ronald "
        },
        "To": [
          {
            "Email": "doghousedev@demomail.com",
            "Name": "Rogue "
          }
        ],
        "Subject": "Email PDF Quote Testing!",
        "TextPart": "Dear customer find attached quote",
        "HTMLPart": "<h3>Dear Rogue , Here us you quote!",
        "Attachments": [
          {
            "ContentType": "application/pdf",
            "Filename": "quote.pdf",
            "Base64Content": base64data
          }
        ]
      }
    ]
  };

  // Send the email
  try {
    const response = await fetch('MY SERVER.COM', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(data),
    });

    if (!response.ok) throw new Error('Email sending failed');
    const responseData = await response.json();
    console.log("Response Data:", responseData);
    // Handle success here
  } catch (error) {
    console.error('Error:', error);
    // Handle error here
  }
};

Hello,

The attached file contains a comma-separated list of character codes.

Please, check your code that converts the result of our export.

Thank you.

the solution wasn't clearly obvious to me but figured it out with the help of chatgpt.

Code: Select all

/* Function to convert PDF data to base64 */
function convertPdfToBase64(report) {
  return new Promise((resolve, reject) => {
    report.renderAsync(() => {
      report.exportDocumentAsync((pdfData) => {
        const byteArray = new Uint8Array(pdfData);
        const pdfBlob = new Blob([byteArray], { type: 'application/pdf' });
        const reader = new FileReader();

        reader.onloadend = function () {
          const base64data = reader.result.split(',')[1];
          resolve(base64data);
        };

        reader.onerror = reject;

        reader.readAsDataURL(pdfBlob);
      }, Stimulsoft.Report.StiExportFormat.Pdf);
    });
  });
}
