接口中返回xml格式内容

复制代码

from fastapi import FastAPI, Response

app = FastAPI()


# ① xml
@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")

我们看下实际返回：

返回的类型是xml格式的，说明返回成功。

接口返回中定制headers

复制代码

@app.get("/legacy_with_headers")
def get_legacy_with_headers_data():
    headers = {"X-Xtoken": "LC", "Content-Language": "en-US"}
    data = """<?xml version="1.0"?>
        <shampoo>
        <Header>
            Apply shampoo here.
        </Header>
        <Body>
            You'll have to use soap here.
            HERE SOMETHING HEADER YOU DEFINED
        </Body>
        </shampoo>
        """
    return Response(content=data, media_type="application/xml", headers=headers)

我们看下实际返回

对应的接口可以正常返回，对应的Headers返回正常。

设置cookie

复制代码

@app.get("/legacy_with_header_cookie")
def legacy_with_header_cookie():
    headers = {"X-Xtoken": "LC-1", "Content-Language": "en-US"}
    data = """<?xml version="1.0"?>
            <shampoo>
            <Header>
                Apply shampoo here.
            </Header>
            <Body>
                You'll have to use soap here.
                HERE SOMETHING HEADER YOU DEFINED AND COOKIE
            </Body>
            </shampoo>
            """
    response = Response(content=data, media_type="application/xml", headers=headers)
    response.set_cookie(key="cookie_key_lc", value="mrli")
    return response

我们看下实际返回

接口可以正常返回我们设置的cookie，headers也可以正常返回。
