$ http JSONP请求在Chrome / Firefox上获得404，在IE中正常运行

Question

I'm developing a simple Hangman application using the random word API . The author says that it's JSONP compatible.

See this Fiddle: https://jsfiddle.net/1t8ur23p/7/

The relevant code is here. This is working correctly in IE and I'm getting a random word every time. But I'm getting a 404 in Firefox and Chrome and I can't tell why.

function getSecretWord() {
  //call the random word API using JSONP request
  $http.jsonp(
      'http://randomword.setgetgo.com/get.php?callback=JSON_CALLBACK'
  ).then(function(response) {
      console.log(response);
      //apply the random word to the local secret word
      $scope.word = response.data.Word;
      //setup the other parts of the game
      $scope.letters = response.data.Word.split("");
      $scope.answerArray = response.data.Word.replace(/./g, '-')
          .split("");
  }).catch(function(response) {

      //debugging... see the contents of the faulty response
      $scope.error = response;

      //there's been an error, just default the word to 'hello'
      $scope.word = 'hello';
      $scope.letters = $scope.word.split("");
      $scope.answerArray = $scope.word.replace(/./g, '-').split(
          "");
  });
}

Are you running your code on a HTTPS page? Because this seems to be a mixed content page issue. I'm seeing the following error on Chrome and Firefox:

Mixed Content: The page at 'https://fiddle.jshell.net/1t8ur23p/7/show/' was loaded over HTTPS, but requested an insecure script 'http://randomword.setgetgo.com/get.php?callback=angular.callbacks._0'. This request has been blocked; the content must be served over HTTPS.

This happens when you try to load a HTTP page from a HTTPS page. You can see that if you run the code from http://jsfiddle.net/1t8ur23p/7/ (http, not https), it works fine.
