我正在使用python的.replace函数将一个字符串替换为一个字符串。

type = ['B','A','C']
q = ''
for i in prov:
    s = str({'filter' : {'match_phrase': {'type':i}}})
    s = s[1:-1]  
    q = q+','+s
Now q looks like this
Output - ",'filter': {'match_phrase': {'type': 'B'}},'filter': {'match_phrase': {'type': 'A'}},'filter': {'match_phrase': {'type': 'C'}}"

现在我想在查询中用“q”字符串替换“type_filter”字符串（如下所示）。

query = r"""{"size": 10 ,"query": {"bool": {"must": [{"multi_match": {"query": "centro","fields": ["name","alias_terms"],"fuzziness": "AUTO"}}],"filter": {"match_phrase": {"category": "Specialty"}} type_filter }}}"""

当我使用下面的替换函数时，我得到了反斜杠（）

c = spec_query.replace("type_filter",q)
c looks like this
'{"size": 10 ,"query": {"bool": {"must": [{"multi_match": {"query": "centro","fields": ["name","alias_terms"],"fuzziness": "AUTO"}}],"filter": {"match_phrase": {"category": "Specialty"}},\'filter\': {\'match_phrase\': {\'prov_type\': \'B\'}},\'filter\': {\'match_phrase\': {\'prov_type\': \'A\'}},\'filter\': {\'match_phrase\': {\'prov_type\': \'C\'}}}}}'

我试过json.dumps和正则表达式来删除反斜杠。我是这样查询的

response = opensearc_client.search(body = c,index ,='proc_spanish')

生成的JSON应该如下所示，这样我就可以在开放查询中运行它，并且它的格式应该是json。

c = {"size": 10 ,"query": {"bool": {"must": [{"multi_match": {"query": "centro","fields": ["name","alias_terms"],"fuzziness": "AUTO"}}],"filter": {"match_phrase": {"category": "Specialty"}},"filter": {"match_phrase": {"type": "B"}},"filter": {"match_phrase": {"type": "A"}},"filter": {"match_phrase": {"type": "C"}}}}}

在使用json.loads和json.dumps函数后运行此查询时，我得到的错误是

RequestError: RequestError(400, 'json_parse_exception', "Unexpected character (''' (code 39)): was expecting double-quote to start field name\n at [Source: (org.opensearch.common.io.stream.InputStreamStreamInput); line: 1, column: 188]")

任何人都可以请帮助如何删除这些额外的反斜杠。提前感谢。
