我正在使用Azure的Cosmos db和使用python的SQL API。
我已经将一些数据上传到了波斯菊数据库,但是现在我想将其删除。
我在这个问题中看到了如何做:Cosmos DB - Delete Document with Python
但是对我来说,这不起作用,这是我的代码:
config = {
'ENDPOINT': "ENDPOINT",
'MASTERKEY': 'key',
'DOCUMENTDB_DATABASE': 'database',
'DOCUMENTDB_COLLECTION': 'collection'
};
# Initialize the Python DocumentDB client
client = document_client.DocumentClient(config['ENDPOINT'], {'masterKey': config['MASTERKEY']})
# use a SQL based query to get a bunch of documents
query = { 'query': 'SELECT * FROM c' }
options = {}
options['enableCrossPartitionQuery'] = True
options['maxItemCount'] = -1
options['partitionKey'] = '2017'
result_iterable = client.QueryDocuments('dbs/database/colls/collection', query, options)
results = list(result_iterable);
print(results)
#client.DeleteDocument('dbs/ToDoList/colls/nc4data/docs/'+result_iterableID,options)
for x in range(0, len (results)):
docID = results[x]['id']
print (docID)
client.DeleteDocument('dbs/database/colls/collection/docs/'+docID, options=options)
print ('deleted', docID)
#print ('delete success')
我的分区键是从2016年到2019年的年份。我试图将选项中的分区键设置为年份之一,就像我上面回答的那样:
options['partitionKey'] = '2017'
我也尝试这样做:
options['partitionKey'] = 2017 (year is string, but I was trying)
options['partitionKey'] = 'year'
options['partitionKey'] = '/year'
当我在选项字典中插入此'partitionKey'时,我会在结果中获得一个Empy列表。
我也试过没有这个'partitionKey',然后我得到了所有数据,但是我得到了这个错误:
{\“错误\”:[\“ x-ms-partitionkey标头中提供的分区键的组件少于集合中定义的组件。

我在上一个线程Cosmos DB - Delete Document with Python中测试了代码,并且工作正常。
import pydocumentdb;
import pydocumentdb.document_client as document_client
config = {
'ENDPOINT': 'Your url',
'MASTERKEY': 'Your master key',
'DOCUMENTDB_DATABASE': 'familydb',
'DOCUMENTDB_COLLECTION': 'familycoll'
};
# Initialize the Python DocumentDB client
client = document_client.DocumentClient(config['ENDPOINT'], {'masterKey': config['MASTERKEY']})
# use a SQL based query to get a bunch of documents
query = { 'query': 'SELECT * FROM server s' }
options = {}
options['enableCrossPartitionQuery'] = True
options['maxItemCount'] = 2
result_iterable = client.QueryDocuments('dbs/familydb/colls/familycoll', query, options)
results = list(result_iterable);
print(results)
client.DeleteDocument('dbs/familydb/colls/familycoll/docs/id1',options)
print 'delete success'
我从github搜索了确切的问题,发现这是由sdk版本引起的。您可以通过Fiddler Tool升级软件包版本或监视https请求。请参阅以下主题:
