是否可以在 Flask 中发出 POST 请求? [英] Is it possible to make POST request in Flask?

问题描述

需要在 Flask 中从服务器端发出 POST 请求.

There is a need to make POST request from server side in Flask.

假设我们有:

@app.route("/test", methods=["POST"])
def test():
    test = request.form["test"]
    return "TEST: %s" % test

@app.route("/index")
def index():
    # Is there something_like_this method in Flask to perform the POST request?
    return something_like_this("/test", { "test" : "My Test Data" })

我在 Flask 文档中没有找到任何具体的内容.有人说 urllib2.urlopen 是问题所在，但我未能将 Flask 和 urlopen 结合起来.真的有可能吗?

I haven't found anything specific in Flask documentation. Some say urllib2.urlopen is the issue but I failed to combine Flask and urlopen. Is it really possible?

推荐答案

是的，要发出 POST 请求，您可以使用 urllib，请参阅 文档.

Yes, to make a POST request you can use urllib, see the documentation.

不过，我建议改用 requests 模块.

I would however recommend to use the requests module instead.

编辑:

我建议您重构代码以提取通用功能:

I suggest you refactor your code to extract the common functionality:

@app.route("/test", methods=["POST"])
def test():
    return _test(request.form["test"])

@app.route("/index")
def index():
    return _test("My Test Data")

def _test(argument):
    return "TEST: %s" % argument
