Javascript $http JSONP请求在Chrome/Firefox上生成404，在IE中正常工作

我正在使用开发一个简单的Hangman应用程序。作者说它与JSONP兼容

看这把小提琴：

相关代码在这里。这在IE中正常工作，每次我都会收到一个随机单词。但我在Firefox和Chrome上得到了404，我不知道为什么

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(
          "");
  });
}

您是否在HTTPS页面上运行代码？因为这似乎是个问题。我在Chrome和Firefox上看到以下错误：

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.

当您尝试从HTTPS页面加载HTTP页面时，会发生这种情况。您可以看到，如果您从（http，而不是https）运行代码，它工作正常。

Ahh。。。就是这样。啊。。。就这样。
