我試圖通過其API讀取保管箱元數據,並將所有文件夾,子文件夾和文件的url路徑寫入數組。 Dropbox基本上返回一個元數據響應對象,顯示某個URL的所有文件和文件夾,然後我必須再次進入每個文件夾才能執行相同的操作,直到我遍歷整個樹。嘗試使用node.js漫步保管箱文件夾樹
現在的問題:
我有「那種」成功地走在整個樹,做到這一點的,但是由於我做的方式我無法發出回調(或事件)當我完成了遍歷所有可能的網址。
此外,我從內部調用一個函數。雖然這似乎工作,但我不知道在Node.js中做一件好事還是壞事。任何意見,這也將不勝感激,因爲我對node.js是相當新的。
我的代碼:
function pathsToArray(metadataarr,callback){ //Call this function and pass the Dropbox metadata array to it, along with a callback function
for (aItem in metadataarray){ //For every folder or file in the metadata(which represents a specific URL)
if (metadataarr[aItem].is_dir){ //It is a folder
dropbox.paths.push(metadataarr[aItem].path+"/"); //Write the path of the folder to my array called 'dropbox.paths'
dropbox.getMetadata(metadataarr[aItem].path.slice(1),function(err, data){ //We go into the folder-->Call the dropbox API to get metadata for the path of the folder.
if (err){
}
else {
pathsToArray(data.contents,function(err){ //Call the function from within itself for the url of the folder. 'data.contents' is where the metadata returned by Dropbox lists files/folders
});
}
});
}
else { //It is a file
dropbox.paths.push(metadataarr[aItem].path); //Write the path of the file to my array called 'dropbox.paths'
}
}
return callback(); //This returns multiple times, instead of only once when everything is ready, and that is the problem!
};
謝謝!
