我需要3个尝试块进行网址编码吗？

Question

我试过了：

String query = "http://maps.googleapis.com/maps/api/geocode/xml?address="+country+"+"+province+"+"+city+"&sensor=false";

try {
    query = URLEncoder.encode(query, "UTF-8");
}
catch (Exception e) {
    println("getLatLonFromAdress URLEncoder error: "+e);
    return  new float[] { -1f, -1f };
} 

但它将网址变为：

http%3A%2F%2Fmaps.googleapis.com%2Fmaps%2Fapi%2Fgeocode%2Fxml%3Faddress%3DCanada%2BAlberta%2BGrande+Cache%26sensor%3Dfalse

所以我只想编码国家，省和城市。在一个试块中处理它是不是很糟糕？像：

try {
    country = URLEncoder.encode(country, "UTF-8");
    province = URLEncoder.encode(province, "UTF-8");
    city = URLEncoder.encode(city, "UTF-8");
}
catch (Exception e) {…}

Answer 1

如果您传递的是“UTF-8”，则不会抛出UnsupportedEncodingException，因为它始终存在。因此，您可以愉快地处理所有这一切。
