angularJs上傳文件-以及遇到的坑

angularJs上傳文件使用的是angular-file-upload控件。

先介紹一下這個控件的一些屬性和一些方法;

FileUploader
屬性
url {String}: 上傳文件的服務器路徑
alias {String}:  包含文件的名稱，默認是file
queue {Array}: 上傳隊列
progress {Number}: 上傳隊列的進度，只讀
headers {Object}: 上傳的頭文件信息， 瀏覽器需支持HTML5
formData {Array}: 與文件一起發送的表單數據
filters {Array}: 在文件加入上傳隊列之前應用過濾器.，如果過濾器返回true則文件加入隊列中
autoUpload {Boolean}: 文件加入隊列之後自動上傳，默認是false
method {String}: 請求方式，默認是POST，瀏覽器需支持HTML5
removeAfterUpload {Boolean}: 文件上傳成功之後從隊列移除，默認是false
isHTML5 {Boolean}: 如果瀏覽器支持HTML5上傳則返回true，只讀
isUploading {Boolean}: 文件正在上傳中返回true，只讀
queueLimit {Number} : 最大上傳文件數量（預定義）
withCredentials {Boolean} : 使用CORS，默認是false， 瀏覽器需支持HTML5
方法
addToQueue function(files[, options[, filters]]) {: Add items to the queue, where files is a {FileList|File|HTMLInputElement}, options is an {Object} andfilters is a {String}.  添加項到上傳隊列中，files 是 {FileList|File|HTMLInputElement}， options 是 {Object} 以及 filters 是 {String}
removeFromQueue function(value) {: Remove an item from the queue, wherevalue is {FileItem} or index of item.  從上傳隊列移除項，value 可以是 {FileItem} 或者項的序號
clearQueue function() {: Removes all elements from the queue.  移除上傳隊列所有的元素
uploadItem function(value) {: Uploads an item, where value is {FileItem} or index of item.  上傳項， value 可以是 {FileItem} 或者項的序號
cancelItem function(value) {: Cancels uploading of item, where value is{FileItem} or index of item.  取消上傳的項
uploadAll function() {: Upload all pending items on the queue.  將上傳隊列中所有的項進行上傳
cancelAll function() {: Cancels all current uploads.  取消所有當前上傳
destroy function() {: Destroys a uploader. 
isFile function(value) {return {Boolean};}: Returns true if value is {File}. 
isFileLikeObject function(value) {return {Boolean};}: Returns true if value is{FileLikeObject}.
getIndexOfItem function({FileItem}) {return {Number};}: Returns the index of the{FileItem} queue element.  返回項在上傳隊列中的序號
getReadyItems function() {return {Array.<FileItems>};}: Return items are ready to upload.  返回準備上傳的項
getNotUploadedItems function() {return {Array.<FileItems>};}: Return an array of all pending items on the queue  返回上傳隊列中未上傳的項
回調函數
onAfterAddingFile function(item) {: 添加文件到上傳隊列後
onWhenAddingFileFailed function(item, filter, options) {: 添加文件到上傳隊列失敗後
onAfterAddingAll function(addedItems) {: 添加所選的所有文件到上傳隊列後
onBeforeUploadItem function(item) {: 文件上傳之前
onProgressItem function(item, progress) {: 文件上傳中
onSuccessItem function(item, response, status, headers) {: 文件上傳成功後
onErrorItem function(item, response, status, headers) {: 文件上傳失敗後
onCancelItem function(item, response, status, headers) { - 文件上傳取消後
onCompleteItem function(item, response, status, headers) {: 文件上傳完成後
onProgressAll function(progress) {: 上傳隊列的所有文件上傳中
onCompleteAll function() {: 上傳隊列的所有文件上傳完成後

成功上傳文件的回調函數順序是：onAfterAddingFile — onAfterAddingAll — onBeforeUploadItem — onProgressItem — onProgressAll — onSuccessItem — onCompleteItem — onCompleteAll
FileItem

removeAfterUpload {Boolean}: Remove this file from the queue after uploading  上傳之後從上傳隊列移除該文件
index {Number} - A sequence number upload. Read only.  上傳文件在上傳隊列中的序號，只讀

Filters（過濾器）
註冊過濾器：
