detecting “we have no imagery” of google maps street view static images

Question

I\'m generating street view static images like so:

https://maps.googleapis.com/maps/api/streetview?size=1080x400&location=%s&fov=90&heading=235&pitch=0&a

Answer 1

Request a google street view image and if it has a specific file size it is a 'Not street view avaible'. I did the follwing:

var url = 'google street view url';

var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'blob';

xhr.onload = function (e) {
  if (this.status == 200) {
    try {
      var image = new Blob([this.response], {type: 'image/jpeg'});

      if (image.size) {
        if (url.indexOf('640x640') > -1 && image.size === 8410) {
          // Not street view
        }

        if (url.indexOf('400x300') > -1 && image.size === 3946) {
           // Not street view
        }
      }
    } catch (err) {
      // IE 9 doesn't support blob
    }
  }
};

xhr.send();
