Flask 与 Python 交互

Question

我创建了一个小型 Flask 应用程序，当我运行它时，无论我选择哪个页面，浏览器的输出都不会改变。 我做错了什么？

from flask import Flask
from perf_api_linux import PerfAPILinux

app = Flask(__name__)


@app.route('/')
@app.route('/index')
@app.route('/health')
@app.route('/RunTest')
def index():
    return "<p>Ready To go on Home Page<p>"
    # return "<p>Hello,   World!</p>"


def health():
    print ("Health Matters")
    return "<p>Hello from HealthCheck<p>"


def RunTest():
    print("Test Execution Beginning")
    PerfAPILinux.execute()
    return("Test Complete")

了解装饰器（

@app.route

是一个装饰器）最重要的一点是它们会影响它们上面的函数。如果您希望浏览器路由应用于您定义的函数，则必须将

@app.route

装饰器放在该函数的正上方。

@app.route('/')
@app.route('/index')
def index():
    # This page can be visited by navigating to / or /index
    return "<p>Ready To go on Home Page<p>"
    # return "<p>Hello,   World!</p>"

@app.route('/health')
def health():
    # This page can be visited by navigating to /health
    print ("Health Matters")
    return "<p>Hello from HealthCheck<p>"

@app.route('/RunTest')
def RunTest():
    # This function is triggered by navigating to /RunTest
    print("Test Execution Beginning")
    PerfAPILinux.execute()
    return("Test Complete")
