下面的代码 会报错 。。。该怎么改呢？有大佬知道吗？
String temp;
void setup(){
size(200,200);
String mainUrl = "http://api.k780.com:88/? app=weather.today&weaid=1&&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json";
JSONObject json;
json = new JSONObject();
json = loadJSONObject(mainUrl);
JSONObject result= json.getJSONObject("result");
String temp = result.getString("temperature_curr");
println(temp);
}
void draw() {
background(255);
fill(0); // Specify font color
text (temp,10,120);
}
