@app.route('/users', methods=['GET', 'POST'])

def users():

print "Hello, World!"

print(request.data)//同：request.get_data()

print(request.json)

如何获取request的参数

在于客户端请求头Headers中参数：Content-Type的设置

以及传参的方式

一、Content-Type:application/json

import requests

url = "http://127.0.0.1:5000/api/registerUser"

payload = "{\n\t\"username\":\"788\",\n\t\"password\":\"rui\"\n}"

headers = {

'Content-Type': "application/json",

'Authorization': "Basic MTUyMzgzNzE3MTM6MXFhejJ3c3g=",

'User-Agent': "PostmanRuntime/7.15.0",

'Accept': "*/*",

'Cache-Control': "no-cache",

'Postman-Token': "b05a50fc-aa0b-42ab-a979-c7b8844b04ee,67ec1de5-247b-415c-a7aa-f110a9dea486",

'Host': "127.0.0.1:5000",

'accept-encoding': "gzip, deflate",

'content-length': "40",

'Connection': "keep-alive",

'cache-control': "no-cache"

}

response = requests.request("POST", url, data=payload, headers=headers)

print(response.text)

此时 ：

通过request.data 获得的数据是json字符串，要序列化json.loads(request.data)才能能用。

通过request.json 取得的数据就是json数据，可以直接使用。

value = request.json.get('key')

二、 Content-Type:application/x-www-form-urlencoded

import requests

url = "http://127.0.0.1:5000/api/registerUser"

querystring = {"username":"body12"}

headers = {

'Content-Type': "application/x-www-form-urlencoded",

'Authorization': "Basic MTUyMzgzNzE3MTM6MXFhejJ3c3g=",

'User-Agent': "PostmanRuntime/7.15.0",

'Accept': "*/*",

'Cache-Control': "no-cache",

'Postman-Token': "bbd54eda-acbf-47af-9b60-0df7f014d490,db8b1060-87dc-46eb-8bf6-72dd701db4a0",

'Host': "127.0.0.1:5000",

'accept-encoding': "gzip, deflate",

'content-length': "",

'Connection': "keep-alive",

'cache-control': "no-cache"

}

response = requests.request("POST", url, headers=headers, params=querystring)

print(response.text)

可以通过 request.args获取参数

print(request.args)

print(request.args.get('username'))

当然你可以通过输出看区别：

request.form

request.args

request.querystring

request.data

request.json
