Question

我遇到Ext.device.filesystem.FileEntry.read（）方法的问题。当我尝试将text / JSON文件作为文本读取时，我得到一个空白文件。任何的想法？看起来像extjs文件阅读器的readastext方法是错误的。

以下不起作用：

   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”就可以了。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);
            }
        }
    });

Ext.device.filesystem.FileEntry.read（） - 类型：“text”返回空白文件
