我有其中显示放置每个订单的下单和类别的订单屏幕。我使用了一个for循环,从API获取订单,但在订单JSON响应它也有项目参数中,其中有多个项目。我无法弄清楚如何将另一个循环中的代码来获取项目列表。所以,请帮我一下吧......谢谢。
我的JSON响应
[
{
"id": 1453,
"total": "407.00",
"line_items": [
{
"id": 34,
"name": "Aloo Chaat Salad",
"product_id": 931,
"quantity": 1,
"total": "90.00",
},
{
"id": 35,
"name": "Aloo Jeera",
"product_id": 1020,
"quantity": 1,
"total": "140.00",
},
{
"id": 36,
"name": "Banana Shake",
"product_id": 963,
"quantity": 1,
"tax_class": "",
"total": "140.00",
}
],
}
]
myModel.dart
class OrderListModel {
final int id;
final String total;
Map line_items = {};
OrderListModel(this.id, this.total, this.line_items);
}
我对获取数据的代码
List<OrderListModel> myAllDatas = [];
Future getDatas() async {
String basicAuth = 'Basic ' +
base64.encode(
utf8.encode('${GlobalVar.consumerKey}:${GlobalVar.secretKey}'));
var response = await http
.get("${GlobalVar.url}wp-json/wc/v2/orders?customer=6", headers: {
'Authorization': basicAuth,
'Accept': 'application/json',
});
if (response.statusCode == 200) {
String responseBody = response.body;
var jsonBody = json.decode(responseBody);
for (var data in jsonBody) // loop for fetching the orders
{
myAllDatas.add(new OrderListModel(data['id'], data['total'],
data['line_items'])); // how to place a loop so that i can fetch the items
inside the line_items parameter too?
}
setState(() {});
} else {
print(response.statusCode);
print(response.body);
}
}
当我取line_items的项目,我只是想获取他们的名字,并通过连续的逗号它们分开。
使用了这样的循环 -
for (var data in body) {
List items = data["line_items"];
for (int i = 0; i < items.length; i++) {
int id = items[i]["id"];
String name = items[i]["name"];
}
}
