httpx 請求實(shí)例

為了最大程度地控制通過網(wǎng)絡(luò)發(fā)送的內(nèi)容，HTTPX 支持構(gòu)建顯式請求實(shí)例：

request = httpx.Request("GET", "https://example.com")

要將實(shí)例分派到網(wǎng)絡(luò)，請創(chuàng)建一個(gè)Client實(shí)例并使用? Request.send()?：

with httpx.Client() as client:
    response = client.send(request)
    ...

如果需要以默認(rèn)的參數(shù)合并不支持的方式混合?client-level?和?request-level?選項(xiàng)，可以使用?.build_request()?，然后對?Request?實(shí)例進(jìn)行任意修改。例如：

headers = {"X-Api-Key": "...", "X-Client-ID": "ABC123"}

with httpx.Client(headers=headers) as client:
    request = client.build_request("GET", "https://api.example.com")
    print(request.headers["X-Client-ID"])  # "ABC123"
    # Don't send the API key for this particular request.
    del request.headers["X-Api-Key"]
    response = client.send(request)
    ...
