Question

我收到这些字符： - http://screencast.com/t/Km9AJZuy8FHi

success: function(files) {
        client.readFile(files[0].name,function(error, contents,s) {
            if (error) {
                return showError(error);  // Something went wrong.
            }
            console.log(contents);
        });
    },
