Python requests用法和django后台处理详解

requests.get(login_url, params={
    "user": user, 
    "password": password, 
})

requests.post(form_submit_url, data={
    "user": user, 
    "password": password, 
},  params={
    "pool": pool, 
})

files = ["a.csv", "b.xml"]

# 注意file需要以binary形式打开。
files = [("files", (os.path.basename(file), open(file, "rb")))
         for file in files]

r = requests.post(url, files=files, data=data, params=params)

session = requests.Session()
session.get(login_url, params)
session.post(form_submit_url, data)

r = requests.post(url, files=files, data=data, params=params)

if r.status_code != 200:
    print(r.status_code, r.reason) # 打印出错信息。
else:
    print(r.content)  # 服务器返回结果

def handler(request):
    return request.GET["pool"]       # 若未传入参数，将抛出异常
    # return request.GET.get("pool") # 当没有传入该参数时，返回None
    # return request.GET.get("pool", "abc") # 默认为abc    

def handler(request):
    return request.POST["user"]       # 若未传入参数，将抛出异常
    # return request.POST.get("user") # 当没有传入该参数时，返回None
    # return request.POST.get("user", "abc") # 默认为abc   

def handler(request):
    for file in request.FILES.getlist("files"):
        name = file.name
        content = file.file.read()      # is binary
        open(name, "wb").write(content) # 保存到本地
