Question

我正试图创造一套可下载内部文本的档案。我曾看到,需要创建一部南盟,以便通过这个论坛。

chrome.downloads.downloads ({ url: url, filename: fileName, ConflictAction: overwrite , SaveAs: false });

然而,当我尝试使用URL.createUrlObject(URL)时,我发现有一类错误。

var blob = new Blob([textFile], {type: application/octet-binary }); var url = URL.createObjectURL(blob);

我正在使用明显的语言。

Answer 1

    chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
  if (request.type === "saveCSV") {
    // for utf8 bom 
    const data =  uFEFF  + request.data;
    const blob = new Blob([data], { type: "text/csv;charset=utf-8" });

    // use BlobReader object to read Blob data
    const reader = new FileReader();
    reader.onload = () => {
      const buffer = reader.result;
      const blobUrl = `data:${blob.type};base64,${btoa(new Uint8Array(buffer).reduce((data, byte) => data + String.fromCharCode(byte),   ))}`;
      chrome.downloads.download({
        url: blobUrl,
        filename: request.filename,
        saveAs: true,
        conflictAction: "uniquify"
      }, () => {
        sendResponse({ success: true });
      });
    };
    reader.readAsArrayBuffer(blob);
    return true;
  }
});

希望这将有助于其他人。

Answer 2

 const binary = atob(codigoBase64);

        const blob = new Blob([binary], { type: "application/pdf" });
        
        const dataURL = `data:${blob.type};base64,${btoa(binary)}`;

        chrome.downloads.download({
            url: dataURL,
            filename: `${nombreArchivo}`,
            saveAs: true, 
        });
