Question

首先我很抱歉因为我的英文太糟糕了。我有一个问题，我怎么知道是下雨还是下雪？我尝试通过temp检查，但它不对。我从openweathermap API获取数据。这是我的codepen： http://codepen.io/khanh1993/full/EybPXG/ 以及检查的条件：

if(fTemp>80){
  $("#icon").html('<i class="fa fa-sun-o fa-fw fa-5x fa-spin" aria-hidden="true"></i>');
  $('body').css("background","url('http://www.walldevil.com/wallpapers/a79/nature-backgrounds-screen-desktop-savers-high-sunshine-wallpapers-images-resolution.jpg')")
}
else if(fTemp>58){
  $("#icon").html('<i class="fa fa-tint fa-fw fa-5x" aria-hidden="true"></i>');
  $('body').css("background","url('http://wallpapercave.com/wp/doNuhh5.jpg')");
}
else if(fTemp>40){
  $('#icon').html('<i class="fa fa-cloud fa-5x fa-fw" aria-hidden="true"></i>');
  $('body').css("background","url('http://eskipaper.com/images/cloud-background-6.jpg')");
}

Answer 1

这是我在openweather API中找到的API文档

   const int DATA_SIZE = 20;
   int data[DATA_SIZE] = {0};

   // Initialize and print array
   init_array(data, DATA_SIZE, 100);
   print_array(data, DATA_SIZE);

   // Find maximum value
   int max = find_max(data, DATA_SIZE);

   cout << "max = " << max << endl;

   return 0;

您可以从{"coord":{"lon":139,"lat":35}, "sys":{"country":"JP","sunrise":1369769524,"sunset":1369821049}, "weather":[{"id":804,"main":"clouds","description":"overcast clouds","icon":"04n"}], "main":{"temp":289.5,"humidity":89,"pressure":1013,"temp_min":287.04,"temp_max":292.04}, "wind":{"speed":7.31,"deg":187.002}, "rain":{"3h":0}, "clouds":{"all":92}, "dt":1369824698, "id":1851632, "name":"Shuzenji", "cod":200}

获取天气

这是我如何得到

response.weather[0].main

现在输出将是“Rain”

如何知道天气下雨，下雪或晒太阳？
