Question

嗨，我是osmapi和python的新手。我正在编写脚本来使用osmapi执行一些查询，直到出现此错误，并且数据似乎可以在此链接https://www.openstreetmap.org/way/77517260上使用，并且对于xml响应https://api.openstreetmap.org/api/0.6/way/77517260也是一样。

当我测试其他方式的ID是否有效时，但该ID 77517260无效，则出现以下错误：

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)
~/.pyenv/versions/3.6.4/lib/python3.6/site-packages/osmapi/OsmApi.py in _OsmResponseToDom(self, response, tag, single)
   2060             all_data = osm_dom.getElementsByTagName(tag)
-> 2061             first_element = all_data[0]
   2062         except (xml.parsers.expat.ExpatError, IndexError) as e:

IndexError: list index out of range

During handling of the above exception, another exception occurred:

    514         data = self._get(uri)
--> 515         ways = self._OsmResponseToDom(data, tag="way")
    516         result = []
    517         for way in ways:

   2065             )
   2066 

XmlResponseInvalidError: The XML response from the OSM API is invalid: IndexError('list index out of range',)

我的python代码：

import osmapi as osm
api = osm.OsmApi()
way = api.NodeWays(77517260)

首先-您应在构造函数中传递url和凭据：

api = osm.OsmApi(api="https://api.openstreetmap.org", username="username", password="secret")

下一步-api/0.6/way/{id}-也许您正在寻找WayGet方法。

代码：

import osmapi as osm api = osm.OsmApi(api="https://api.openstreetmap.org", username="username", password="secret") way = api.WayGet(77517260)

Python：使用osmapi执行查询时，列表索引超出范围
