您可以使用 phonegap 文件 api 从服务器下载您想要的文件。检查文档以获取更多详细信息 - FileTransfer API
这是一个示例代码,用于下载 pdf 文件并将其保存在您的 sdcard 中。
window.appRootDirName = "download_test";
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log("device is ready");
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function fail() {
console.log("failed to get filesystem");
}
function gotFS(fileSystem) {
console.log("filesystem got");
window.fileSystem = fileSystem;
fileSystem.root.getDirectory(window.appRootDirName, {
create : true,
exclusive : false
}, dirReady, fail);
}
function dirReady(entry) {
window.appRootDir = entry;
console.log("application dir is ready");
}
downloadFile = function(){
var fileTransfer = new FileTransfer();
var url = "http://www.irs.gov/pub/irs-pdf/fw4.pdf";
var filePath = window.appRootDir.fullPath + "/test.pdf";
fileTransfer.download(
url,
filePath,
function(entry) {
alert("download complete: " + entry.fullPath);
},
function(error) {
alert("download error" + error.source);
}
);
}

** 您必须添加插件文件 API,phonegap 中的文件传输 (3.0+)
function downloadPDF(url, fileName, folder) {
var fileTransfer = new FileTransfer();
var uri = encodeURI(url);
var fileURL = folder + fileName;
fileTransfer.download(
uri,
fileURL,
function(entry) {
alert("complete");
console.log("download complete: " + entry.toURL());
},
function(error) {
alert("upload error code" + error.code);
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
false,
{
headers: {
"Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
}
}
);
}
