在 json 请求正文中使用 \n 传递文本会在 fastapi 中提供无法处理的实体

Question

我正在尝试将多行文本传递给 fastApi 代码。我的代码看起来像

from fastapi import FastAPI
from pydantic import BaseModel

from model import predictT5

testApp = FastAPI() # create an app

@testApp.get("/") # set root directory

# pydantic models
class TextIn(BaseModel):
    text: str
class TextOut(BaseModel):
    Summary: dict 

    # routes
def root():
    return {"message":"jmj"}

@testApp.post("/predict", response_model=TextOut, status_code=200)
def get_prediction(payload: TextIn):
    """
    Gets a text and runs through T5 & outputs summary
    """
    text = payload.text
    t5Summary = predictT5(text)

这适用于像

这样的请求

curl -X 'POST' \
  'http://127.0.0.1:8000/predict' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "text": "A dictionary that maps attention modules to devices. For reference, the t5 models have the following number of attention modules:"
}'

但是，如果我用 \n 拆分文本并有一个像

这样的请求正文

curl -X 'POST' \
  'http://127.0.0.1:8000/predict' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "text": "A dictionary that maps attention modules to devices.  
For reference, the t5 models have the following number of attention modules:"
}'

明白了

Error: Unprocessable Entity "msg": "Invalid control character at: line 2 column 285 (char 286)", "type": "value_error.jsondecode",

有人知道怎么处理吗？谢谢！

根据 this answer，JSON.

中不允许使用多行字符串

来自同一来源：“您需要用 \n 替换所有换行符”

在 json 请求正文中使用 \n 传递文本会在 fastapi 中提供无法处理的实体

Passing text with \n in json request body gives unprocessable entity in fastapi
