title: JSON, CURL and Google's geolocation
body: <p>I am trying to use Google's geolocating "browserlocation" service.
  I have it figured so far that when I try something like</p>
  
  <pre><code>https://maps.googleapis.com/maps/api/browserlocation/json?browser=firefox&amp;sensor=true&amp;
  wifi=mac:00-14-bf-28-80-69|ssid:10160|ss:-26&amp;
  wifi=mac:00-26-50-38-ca-11|ssid:2WIRE084|ss:-69&amp;
  wifi=mac:34-ef-44-7c-0e-b1|ssid:2WIRE202|ss:-70&amp;
  wifi=mac:00-1f-b3-64-b3-f1|ssid:2WIRE605|ss:-74&amp;
  wifi=mac:00-26-50-e3-1f-81|ssid:2WIRE137|ss:-79&amp;
  wifi=mac:00-1d-5a-ef-4d-b9|ssid:2WIRE495|ss:-81&amp;
  wifi=mac:c0-83-0a-69-c4-b9|ssid:2WIRE431|ss:-81&amp;
  wifi=mac:30-46-9a-43-3d-71|ssid:MacAdamN|ss:-84&amp;
  wifi=mac:64-0f-28-bf-e2-91|ssid:2WIRE552|ss:-86&amp;
  wifi=mac:00-14-d1-cd-a4-88|ssid:TRENDnet637|ss:-86&amp;
  wifi=mac:00-23-5e-b0-70-90|ssid:AppleWiFi|ss:-86&amp;
  wifi=mac:00-23-5e-af-39-a0|ssid:AppleWiFi|ss:-86&amp;
  wifi=mac:00-1d-d1-55-0d-90|ssid:HOME-0D92|ss:-88
  </code></pre>
  
  <p>in the browser I get pretty accurate results, check it out for yourself.
  But when I want to use a JSON file to pass the data with curl like</p>
  
  <pre><code>curl -i -X POST -d @ssids.json "https://maps.googleapis.com/maps/api/browserlocation/json?browser=firefox&amp;sensor=true"
  </code></pre>
  
  <p>I get horrible accuracy ("accuracy" : 18000.0,).
  The content of the file ssids.json looks like this:</p>
  
  <pre><code>{
  "wifi_access_points": [

  <p>Somehow I know the content of the file is not properly transmitted, but I have NI idea why ...</p>
  
  <p>Would appreciate help, thank you.</p>
