FAST API-错误值不是有效的整数

Question

做一个教程来创建一个休息 API，我的 get("posts/latest") 不起作用。该教程说这可能是因为快速 API 从上到下读取并且它认为路径是 (posts/{id}) 路径。但是，我明白这一点：我已将其移至该功能之前，但仍然出现错误？

    from random import randrange
from typing import Optional
from fastapi import Body, FastAPI, Response , status
from pydantic import BaseModel

app= FastAPI()

class Post(BaseModel):
    title: str
    content: str
    Published: bool = True
    rating: Optional[int] = None

my_post = [{"title": "title of post 1", "content": "content of post 1", "id": 2},{"title": "title of post 2","content":"content of post 2", "id":3}]

def find_post(id):
    for p in my_post:
        if p["id"] == id:
         return p

@app.post("/posts")
def create_post(post: Post):
    post_dict= post.dict()
    post_dict['id']= randrange(0,10000)
    my_post.append(post_dict)
    print(post)
    return { "new_post": post_dict }
    
@app.get("/posts")
async def get_a_post():
    return {"message": "Welcome to my API"}

@app.get("posts/latest")
def get_latest():
    latest_post=my_post[len(my_post-1)]
    latest_id= latest_post["id"]
    print(latest_post)
    return {"post":f"here you go - latest post has an id of { latest_id}"}

@app.get("/posts/{id}")
def get_posts(id: int , respose: Response):
    post= find_post(id)
    print(post)
    return{"here is the post": post}

我打赌你只是忘记了路径名中的斜杠，所以路径不匹配

关注

@app.get("posts/latest")

路径的开头应该有斜线

@app.get("/posts/latest")
