我在想，如何才能将我的会话Id从登录发送到flutter中的其他rest api调用。我在这里的情况是，我希望有一个登录屏幕和产品列表页面。我成功地开发了带身份验证的登录页面。以下是代码片段

登录按钮：

 RaisedButton(
          onPressed: () {
            ApiProvider().userLogin().then((value) => {});
          },
          child: Text('Login'),
        )

ApiProiver.dart：

 Future userLogin() async {
   var options = Options(
    headers: {"Content-Type": "application/json"},
   );
  var body ={
   "jsonrpc" : "2.0",
   "params":{
    "login":"admin",
    "password":"admin",
    "db":"food_app"
  }
 };

 Response response = await dio.post('http://food_app.com/web/session/authenticate',options:options, 
 data: body);
 print("Response $response");
 final cookies = response.headers.map['set-cookie'];
 print("Cookie,$cookies");
}

输出：

  Response :

  {"jsonrpc": "2.0", 
    "id": null,
    "result": 
            {"uid": 2, 
             "is_system": true, 
             "is_admin": true, 
             "db": "food_app",   
            "name":  "Administrator", 
            "username": "admin", 
           "web.base.url": "http://food_app.com",
   }
 }

Cookie：

[session_id=d446d3ef6bd536ef8e0bf6f1c9ba3a40c92ccb99; Expires=Thu, 21-Jan-2021 08:59:42 
GMT; Max-Age=7776000; HttpOnly; Path=/]

Result is ok!!!!!!!!!!!!!!!

我从上面的代码中获得了cookies/会话id，现在我的问题是如何将会话id传递给下一个api调用

Future fetchProducts() async {
 var options = Options(
   headers: {"Content-Type": "application/json"},
  );
  var body =
     {
       "jsonrpc" : "2.0",
      "params":{ }
     };
  Response response = await dio.post('http://food_app.com/api/get_products',options: options, data:body );
  }

以下是接受上述接口调用:slight_smile的python测试脚本：

 odoo_url = "https://food_app.com"

 headers = {'Content-type': 'application/json'}

 myobj = {"jsonrpc":"2.0","params":{'db':'food_app','login':'admin','password':'admin'}}
     
 session_details = requests.get(url=odoo_url + '/web/session/authenticate', data=json.dumps(myobj), 
                                  headers=headers)
 session_id = str(session_details.cookies.get('session_id'))
 print("Session id")
 print(session_id)
 cookies = {
 'session_id': session_id
}

#列出所有产品GET方法

 url_get = 'http://food_app.com/api/get_products'
 headers = {'Content-type': 'application/json'}
get_products = requests.get(url_get, cookies=cookies)
json_data = json.loads(get_products.text)
for product in json_data['response']:
  print(product['name'])

上面的python代码命中api并返回正确的响应

Session :

Product Names:
Calamari & Rice in Orange Souce
Chicken Wings in Buffalo Sauce
Mixed Vegatables, Paprika & Chips - Dish 1
New York Strip Steak  
Roasted Brussels Sprout Salad
Salmon in Carrot Souce
Vegetable Salad with Avocado & Rice

请编辑我的fetchProducts()方法，以便通过会话从api获取响应。

您需要使用cookie manager

示例

import 'package:dio/dio.dart';
import 'package:dio_cookie_manager/dio_cookie_manager.dart';
import 'package:cookie_jar/cookie_jar.dart';

main() async {
  var dio =  Dio();
  var cookieJar=CookieJar();
  dio.interceptors.add(CookieManager(cookieJar));
  
  // first request, and save cookies (CookieManager do it).
  await dio.get("https://baidu.com/");
  
  // Print cookies
  // print(await cookieJar.loadForRequest(Uri.parse("https://baidu.com/")));

  // second request with the cookies
  await dio.get("https://baidu.com/");
  ... 
}
