Flask不能识别两个URL参数 [英] Flask not recognising two URL parameters

本文介绍了Flask不能识别两个URL参数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述



如果我这样做的话:



pre> curl -i http://127.0.0.1:5000/api/journeys/count?startStationName=Hansard%20Mews,%20Shepherds%20Bush&endStationName=Farringdon%20Lane,%20Clerkenwell

然后我的代码是:

<$ p $打印请求.args $ b $打印请求.args $($) b startStationName = request.args.get('startStationName')
endStationName = request.args.get('endStationName')

应该打印一个带有 startStationName endStationName 的字典。



然而,只有第一个参数被接收:

$ $ $ $ $ $ $ $ $ ImmutableMultiDict([( 'startStationName',u'Hansard Mews,Shepherds Bush')])

有人知道我是什么是吗?错了?我有一种感觉,一定有某种愚蠢的错误或误解的地方,但我一直在寻找一个小时,无法找到它。

解决方案

shell & 解释为 将命令放在后台字符中。为了防止这种情况,请引用整个URL:

  curl -ihttp://127.0.0.1:5000/api/journeys / count?startStationName = Hansard%20Mews,%20Shepherds%20Bush& endStationName = Farringdon%20Lane,%20Clerkenwell


I'm trying to send two parameters to a URL routed with Flask.

If I do:

curl -i http://127.0.0.1:5000/api/journeys/count?startStationName=Hansard%20Mews,%20Shepherds%20Bush&endStationName=Farringdon%20Lane,%20Clerkenwell

Then my code which is:

@application.route('/api/journeys/count', methods=['GET'])
def journeys():
    print request.args
    startStationName = request.args.get('startStationName')
    endStationName = request.args.get('endStationName')

Should print a dict with startStationName and endStationName defined.

However, instead, only the first parameter seems to be received:

ImmutableMultiDict([('startStationName', u'Hansard Mews, Shepherds Bush')])

Anybody got any idea what I'm doing wrong? I have a feeling there must be some kind of stupid mistake or misunderstanding somewhere but I've been looking for an hour and can't find it.

解决方案

Your shell interprets the & as a put the command in the background character. To prevent this, quote the whole URL:

curl -i "http://127.0.0.1:5000/api/journeys/count?startStationName=Hansard%20Mews,%20Shepherds%20Bush&endStationName=Farringdon%20Lane,%20Clerkenwell"
