* 获取用户本周已摄入的营养元素的量: `getUser`得到当前用户的信息,解析后用`MyUser`的`getEaten_elements()`获取到Element对象.里面有各种元素信息
* **根据多个食材组合来搜菜**
```java
List<String> materialList = new ArrayList<>();
materialList.add("土豆");
materialList.add("茄子");
WebUtil.getInstance().getMenusByMaterials(materialList, new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String json = response.body().string();
FoodMenu[] menus = new Gson().fromJson(json, FoodMenu[].class);
for (FoodMenu menu : menus) {
System.out.println(menu.getName());
}
}
});
```
* **用户的浏览历史: 添加用户和菜谱的多对多关系**
```java
//获取历史记录 传入username
WebUtil.getInstance().getEatenHistory("test5", new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String json = response.body().string();
History[] histories = new Gson().fromJson(json, History[].class);
System.out.println(Arrays.toString(histories));
}
});
//添加历史记录 传入username 和 Menu的名字
WebUtil.getInstance().addEatenHistory("test5", "多味茄子泥", new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String json = response.body().string();
History history = new Gson().fromJson(json, History.class);
System.out.println(history);
}
});
```
* 菜名搜索: `getMenu`方法,传入菜名(菜名通过其他的各种关联方式获取) (menu.calorie是直接爬到的卡路里值,营养元素里的menu.elements.calorie卡路里是根据每个食材的卡路里计算的,相对来说,menu.calorie的值更准确)
* 功效搜菜 `getMenuClassification`传入分类(功效)参数,比如川菜.搜到所有的川菜名字.然后可以用菜名搜索搜某个菜的详细信息
