react native 網路get請求方式參數不可為undefined(為空白的話預設變為)或null

錯誤寫法:

export function addToCartAction(isRefreshing, loading, spId, number, spfId = null, pgId = null) {    console.warn(‘==>‘,spId+":"+number);    return  (isRefreshing || loading) ?         {types: [FETCH_ADD_TO_CART.code, SUCCESS_ADD_TO_CART, FAILURE_ADD_TO_CART],            callAPI: () => request(FETCH_ADD_TO_CART.url+‘?spId=‘+spId+‘&number=‘+number+‘&spfId=‘+spfId+‘&pgId=‘+pgId),            payload: {isRefreshing, loading}        } : {type: CLEAR_ADD_TO_CART, isRefreshing, loading};}

正確寫法:

export function addToCartAction(isRefreshing, loading, spId, number) {    console.warn(‘==>‘,spId+":"+number);    return  (isRefreshing || loading) ?         {types: [FETCH_ADD_TO_CART.code, SUCCESS_ADD_TO_CART, FAILURE_ADD_TO_CART],            callAPI: () => request(FETCH_ADD_TO_CART.url+‘?spId=‘+spId+‘&number=‘+number),            payload: {isRefreshing, loading}        } : {type: CLEAR_ADD_TO_CART, isRefreshing, loading};}
