如何以及在哪里保存上传的文件与ng-flow

Question

首先，我使用ng-flow (angular.js框架上的html5文件上传扩展名)

我的文件上传，我在控制台记录事件。但我不知道在哪里和如何拯救他们。

这是我的html代码，上传被称为。

<div flow-init flow-files-submitted="$flow.upload()">   
<div class="drop" flow-drop ng-class="dropClass">
    <span class="btn btn-default" flow-btn>Upload File</span>
    <span class="btn btn-default" flow-btn flow-directory ng-show="$flow.supportDirectory">Upload Folder</span>
    <b>OR</b>
    Drag And Drop your file here
</div>

这是我的配置

app.config(['flowFactoryProvider', function (flowFactoryProvider) {
  flowFactoryProvider.defaults = {
    target: 'upload.php',
    permanentErrors: [404, 500, 501],
    maxChunkRetries: 1,
    chunkRetryInterval: 5000,
    simultaneousUploads: 4,
    singleFile: true
  };
  flowFactoryProvider.on('catchAll', function (event) {
    console.log('catchAll', arguments);
  });
  // Can be used with different implementations of Flow.js
  // flowFactoryProvider.factory = fustyFlowFactory;
}]);

upload.php被调用，$_GET已满数据，

<script>alert('alert' + array(8) {
  ["flowChunkNumber"]=>
  string(1) "1"
  ["flowChunkSize"]=>
  string(7) "1048576"
  ["flowCurrentChunkSize"]=>
  string(6) "807855"
  ["flowTotalSize"]=>
  string(6) "807855"
  ["flowIdentifier"]=>
  string(11) "807855-3png"
  ["flowFilename"]=>
  string(5) "3.png"
  ["flowRelativePath"]=>
  string(5) "3.png"
  ["flowTotalChunks"]=>
  string(1) "1"
}
)</script>

但是当我在这里的时候，我要做什么来保存我的文件?

我试着在flowFilename和flowRelativePath上做move_uploaded_file()，但没有任何附加。

my new in js.

谢谢。

查看upload.php示例脚本:

https://github.com/flowjs/flow.js/blob/master/samples/Backend%20on%20PHP.md

// init the destination file (format <filename.ext>.part<#chunk>
// the file is stored in a temporary directory
$temp_dir = 'temp/'.$_POST['flowIdentifier'];
$dest_file = $temp_dir.'/'.$_POST['flowFilename'].'.part'.$_POST['flowChunkNumber'];

使用flow.js上传图像后，将向服务器发送一个新的post请求。您需要处理这个POST请求并在之后操作该文件。

如果你使用Java + Spring MVC，它看起来像

@RequestMapping(value = "/upload",
        method = RequestMethod.POST,
        produces = MediaType.APPLICATION_JSON_VALUE)
public void handleFileUpload(@RequestParam("file") MultipartFile file) {
    log.debug("REST request to handleFileUpload");
    try {
        BufferedOutputStream stream =
                new BufferedOutputStream(new FileOutputStream(new File(path + file.getName())));
        stream.write(file.getBytes());
        stream.close();
        log.debug("You successfully uploaded " + file.getName() + "!");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

我刚刚花了半天的时间与ng-flow工作，并希望张贴解决方案，这为PHP。它没有利用分块和恢复功能，我只是需要一些不需要刷新页面就可以上传的东西。

首先,flow-init="{target: '/upload'， testChunks:false}"示例

<div flow-init="{target: '/upload', testChunks:false}" flow-files-submitted="$flow.upload()" flow-file-success="$file.msg = $message">
            <input type="file" flow-btn />
            <span flow-btn>Upload File</span>
</div>

,

它现在应该POST一个请求到"/upload".....在该请求中存在一个$_FILES数组。

一行代码为我保存了文件:

$result=move_uploaded_file($_FILES['file']['tmp_name'],'yourfilename');

---

如果你想通过你的角控制器来控制这个，你可以这样设置值:

    $scope.uploader={};
    $scope.upload = function (id) {
        $scope.uploader.flow.opts.testChunks=false;
        $scope.uploader.flow.opts.target='/upload;
        $scope.uploader.flow.upload();
    }

并在HTML中添加:

<div flow-init flow-name="uploader.flow">
<button flow-btn>Add files</button>
<div>

是

创建一个名为uploads的文件夹表示将临时文件移动到这里，然后在php脚本中添加代码。

$uploads_dir = 'uploads';
$target_file = $uploads_dir .'/'. basename($_FILES['file']['name']);
move_uploaded_file($_FILES['file']['tmp_name'],$target_file);
