我正在尝试(非常简单)使用网络获取相机目录的文件列表。 我正在尝试的代码如下:
function displayPhotos(id) {
try {
var Dir, path, items;
if ((window.blackberry === undefined) || (blackberry.io === undefined) || (blackberry.io.file === undefined)) {
appendContent("photoDetails", "<p><i><b>blackberry.io.file</b> object not found (likely cause is WebWorks APIs are not supported by this user agent).</i></p>");
debug.log("displayPhotos", "blackberry.io.file object is undefined.", debug.error);
return false;
}
Dir = blackberry.io.dir;
path = "";
path = "file:///Device/home/user/camera"";
items = Dir.listFiles(path);
console.log(items);
//setContent(id, formatAsHTML(path, items));
}
catch(e) {
console.log("displayPhotos", e, debug.exception);
}
}
我得到的全部是错误1004 - 我认为这是基于权限的,但我不相信我无法在相机上读取读取失败 - 任何人都知道什么?
干杯!

好吧,我想通了,希望这可以帮助任何人获得可怕的黑莓网络错误1004。
您需要更改要存储的路径中的设备。真的是这样的。这个例子有效:
function displayPhotos(myFolder) {
try {
var Dir, path, items;
Dir = blackberry.io.dir;
path = "";
if (myFolder != undefined){
path = myFolder;
} else {
path = "file:///store/home/user/pictures";
//file:///store/home/user/camera
}
items = Dir.listFiles(path);
return items;
}
catch(e) {
console.log("displayPhotos", e, debug.exception);
}
}
function displayFiles(myFolder) {
try {
console.log("displayFiles", "in " + myFolder);
return displayPhotos(myFolder);
}
catch(e) {
console.log("displayFiles", e, debug.exception);
}
}
您可以这样称呼它:
displayFiles();
或指定如下文件夹:
displayFiles("file:///store/home/user/camera");
返回文件名数组。
希望这有助于某人!
