Question

我正在尝试将数据传递到索引/根URL上的python flask服务器。有没有办法做到这一点或我做错了什么？

以下是我的代码：

＆＃13;

import json
from flask import Flask
app = Flask(__name__)

@app.route('/<data>', methods=['POST'])
def index(data):
	#test = request.args.get('test')
	return data

＆＃13;

当我运行命令时，它失败

curl  -d "data=123" http://localhost:9000/

python服务器的结果

"POST / HTTP/1.1" 404 -

curl命令的响应

＆＃13;

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title>
<h1>Not Found</h1>
<p>The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.</p>

＆＃13;

决议

＆＃13;

@app.route('/', methods=['POST'])
def index():
	return request.form.get('data')

＆＃13;

有了请求

curl  -d 'data=test' http://localhost:9000/

输出是测试

Answer 1

您的路线定义需要/<somedata>的请求。如果省略<somedata>，则无法解析。

要POST json到/，请执行以下操作：

from flask import Flask, request, jsonify
app = Flask(__name__)


@app.route('/', methods=['POST'])
def index():
    data = request.get_json(force=True)
    return jsonify({'res':data})


if __name__ == '__main__':
    app.run(debug=True)

你可以通过这样做来测试：

$ curl -d '{"foo":"bar"}' localhost:5000/

要POST表单数据到/，就像您在示例中所做的那样，

data = request.form['foo']
return data

代替。用

进行测试

$ curl -d 'foo=bar' localhost:5000/

要通过urlquery将字符串传递给您的路线，您可以执行以下操作：

@app.route('/<string:data>', methods=['POST'])
def index(data):
    return data

用

测试

$ curl -X POST localhost:5000/somestring

Answer 2

您可能想要这样做：

@app.route('/<data>', methods=['POST'])
def index(data):
    return json.dumps(data)

虽然我使用blueprint.route是诚实的，而不是app.route。

Answer 3

对我来说，这很好用。

@api.route('/api/v3/ticket/<string:key>/<int:id>'

我相信它是<type:var>组合。

@app.route('/<data>', methods=['POST'])
def index(data):
    #test = request.args.get('test')
    print data

使用更多解释进行编辑。当我运行你的问题。像这样

然后当你返回这样的数据时，

@app.route('/<data>', methods=['POST'])
def index(data):
    #test = request.args.get('test')
    return data

我想，最后尝试一下，它会对你有用。

为什么@ app.route（＆＃39; / <data>＆＃39;）？不工作？
