//adds the pre-encoded query parameter to this URL's query string
addEncodedQueryParameter(String encodedName,String encodedValue)

//encodes the query parameter using UTF-8 and adds it to this URL's query string
addQueryParameter(String name,String value)

注意：如果已经存在具有此名称的名称/值对,则这些函数将只添加另一对

setEncodedQueryParameter(String encodedName,String encodedValue)

setQueryParameter(String name,则这些函数将删除它们,并且仅在添加此新对之后
 
 
例：
 
  
 
HttpUrl url = new HttpUrl.Builder()
    .scheme("https")
    .host("www.google.com")
    .addPathSegment("search")
    .addQueryParameter("q","polar bears")
    .build();
