我在angularjs中使用elasticsearch javascript api。这工作得非常好，但我需要通过中间件查询elasticsearch服务来过滤危险请求（删除，更新）。中间件使用'GET'但API默认使用'POST'查询。
根据文档我可以指定一个参数'method'来使用API的'GET'查询： API Conventions
它与'POST'一起使用但是'GET'失败，“GET”并且我有一个错误：
Error: elasticQuery.search(...) is undefined
我该怎么办？ “获取”可以使用长而复杂的查询，如下例所示？
这是我尝试的方式：
return elasticQuery.search({
method : 'GET',
index: 'indexbotanic',
from: 0
size: 10,
body: {
"fields" : ["C_COLLECTIONCODE", "T_SCIENTIFICNAME", "T_SCIENTIFICNAMEAUTHORSHIP", "T_SPECIFICEPITHET", "T_KINGDOM", "T_PHYLUM", "T_CLASS_", "T_ORDER_", "T_FAMILY", "T_GENUS", "T_SUBGENUS", "T_VERNACULARNAME", "O_CATALOGNUMBER", "O_RECORDNUMBER", "O_CREATED", "O_SEX", "I_INSTITUTIONCODE", "D_DETERMINATIONID", "D_IDENTIFIEDBY", "M_IDENTIFIER", "E_RECORDNUMBER", "E_RECORDEDBY", "L_CONTINENT", "L_COUNTRY", "L_COUNTRYCODE", "L_COUNTY", "L_LOCALITY"],

}
},
"sort" : "_score"
}
}).then(function (response) {
...
}
例如这项工作与GET：
curl -XGET 'http://localhost:9200/index/tablename/_search?pretty' -d '{
"query": {
"query_string": {
"query":"*keysearch*",
"fields": ["field1","field2","field3"]
}
}
}'
那么如何强制api用“-d'{....}'”发送get？ 非常感谢

尝试使用此客户端：https://github.com/YousefED/elasticsearch.angular.simple并将POST更改为GET。我不确定哪些浏览器支持GET请求，但是你可能会遇到限制。
