FastAPI 学习之路（四十二）定制返回Response

我们想要在接口中返回xml格式的内容，我们应该如何实现呢。

from fastapi import FastAPI,Response
@app.get("/legacy/")
def get_legacy_data():
    data = """<?xml version="1.0"?>
    <shampoo>
    <Header>
        Apply shampoo here.
    </Header>
    <Body>
        You'll have to use soap here.
    </Body>
    </shampoo>
    """
    return Response(content=data, media_type="application/xml")
if __name__ == "__main__":
    uvicorn.run(app, host="127.0.0.1", port=8000)

那么我们请求下看下接口的实际返回。

那么我们看下返回类型是xml格式的。

在返回的时候，有时候我们需要在返回的headers。我们应该如何实现呢

@app.get("/legacy/")
def get_legacy_data():
    headers = {"X-Cat": "leizi", "Content-Language": "en-US"}
    data = """<?xml version="1.0"?>
    <shampoo>
    <Header>
        Apply shampoo here.
    </Header>
    <Body>
        You'll have to use soap here.
    </Body>
    </shampoo>
    """
    return Response(content=data, media_type="application/xml",
                    headers=headers)

其实很简单。我们可以请求下

对应的接口可以正常返回，对应的Headers返回正常。

要想设置cookie也很简单

@app.get("/legacy/")
def get_legacy_data(response: Response):
    headers = {"X-Cat": "leizi", "Content-Language": "en-US"}
    data = """<?xml version="1.0"?>
    <shampoo>
    <Header>
        Apply shampoo here.
    </Header>
    <Body>
        You'll have to use soap here.
    </Body>r
    </shampoo>
    """
    response.set_cookie(key="message", value="hello",path='/legacy/') 

　　return Response(content=data, media_type="application/xml", headers=headers)
