如何将base64数据作为png图像保存到服务器？

Question

How can i save a base64data string as png image to server?

Below code is for php but i am using nodejs as backend. I am sending base64data through ajax call.

list($type, $data) = explode(';', $data);
list(, $data)      = explode(',', $data);
$data = base64_decode($data);
file_put_contents('myDirectory/filename.png', $data);

You can use the filesystem API .

var fs = require('fs');
fs.writeFile("/tmp/test.png", $data, "binary", function(err) {
  if(err) {
    console.log(err);
  } else {
    console.log("The file was saved!");
  }
});
