如何在python搜索API中获取文档ID？

Question

我正在使用带有Python语言的Google App Engine开发地图网站，并使用Search API应用于我的网站（https://cloud.google.com/appengine/training/fts_intro/lesson2）。将它放入索引后如何获得doccument id？我做了如下，但没有得到doc_id：

fields = [
    search.TextField(name = 'userid', value = request.userid),
    search.NumberField(name = 'zoom', value = request.zoom),
    search.TextField(name = 'title', value = request.title),
    search.TextField(name = 'content', value = request.content),
    search.GeoField(name = 'location', value = search.GeoPoint(request.lat, request.lng))
]

d = search.Document(fields = fields)
search.Index(name = _INDEX_NAME).put(d)
doc_id = d.doc_id

Answer 1

请参阅full documentation：

results = search.Index(name=_INDEX_NAME).put(d)
doc_id = results[0].id
