程序结构如下：

源码如下：

application.py

from flask import Flask
from controller import index_page

app = Flask(__name__)

app.register_blueprint(index_page, url_prefix = "/it1995")

if __name__ == "__main__":
    app.run(host = "0.0.0.0", debug = True)

controller.py

from flask import Flask, Blueprint, request

index_page = Blueprint("index_page", __name__)

@index_page.route("/")
def index_page_index():
    return "index_page"

@index_page.route("/my")
def hell():
    return "Hello World"

@index_page.route("/get")
def get():
    req = request.values
    var_a = req["a"] if "a" in req else "Hello"
    return "request:%s, params: %s, var_a: %s" % (request.method, request.args, var_a)

@index_page.route("/post", methods = ["POST"])
def post():
    req = request.values
    var_a = req["a"] if "a" in req else "Hello"
    return "request:%s, params: %s, var_a: %s" % (request.method, request.args, var_a)

@index_page.route("/upload", methods = ["POST"])
def upload():
    f = request.files["file"] if "file" in request.files else None
    return "request:%s, params: %s, file: %s" % (request.method, request.files, f)

这里有两点要注意：

一个是上传文件：

另外一个是在post方法中当url含有a=bget,在body中a=bpost如下：

从中可以看到这个有个坑在post中，如果有url中含有相同的参数，会使用url上的。

这点要注意下。
