Ext.device.filesystem.FileEntry.read() - 类型："text" returns 空白文件

Question

我遇到了 Ext.device.filesystem.FileEntry.read() 方法的问题。当我尝试以文本形式读取 text/JSON 文件时，我得到一个空白文件。任何的想法？看起来 extjs 文件的 readastext 方法 reader 有问题。

以下无效：

   var fileEntry = new Ext.device.filesystem.FileEntry(newFilePath, fileSystem);
    fileEntry.read({
        //type: "binaryString",
        encoding: 'UTF8',
        type: "text",
        //type: "text",
        success: function(fileData) {
            console.log('--- fileData');
            console.log(fileData);
            console.log('//--- fileData');
            self.onUploadJSONSuccess(fileData, fileName, networkId, activityId, section, showWaitScreen, callback);
        },
        failure: function(error) {
            if(showWaitScreen) {
                console.log('Failed to read file: ' + error);
                Ext.Msg.alert('Failed to read file: ' + error);
            }
        }
    });

但是如果我将类型从 "text" 更改为 "binaryString"，它会读取文件但当然会弄乱特殊字符。

   var fileEntry = new Ext.device.filesystem.FileEntry(newFilePath, fileSystem);
    fileEntry.read({
        type: "binaryString",
        success: function(fileData) {
            console.log('--- fileData');
            console.log(fileData);
            console.log('//--- fileData');
            self.onUploadJSONSuccess(fileData, fileName, networkId, activityId, section, showWaitScreen, callback);
        },
        failure: function(error) {
            if(showWaitScreen) {
                console.log('Failed to read file: ' + error);
                Ext.Msg.alert('Failed to read file: ' + error);
            }
        }
    });

将编码更改为 'UTF-8' 即可。因此，工作代码如下：

    fileEntry.read({
        //type: "binaryString",
        type: "text",
        encoding: "UTF-8",
        success: function(fileData) {
            console.log('--- fileData');
            console.log(fileData);
            console.log('//--- fileData');
            self.onUploadJSONSuccess(fileData, fileName, networkId, activityId, section, showWaitScreen, callback);
        },
        failure: function(error) {
            if(showWaitScreen) {
                console.log('Failed to read file: ' + error);
                Ext.Msg.alert('Failed to read file: ' + error);
            }
        }
    });
