使用golang在具有多个条件的mongo查询中发布

我能够通过

$and

var AndQuery []map[string]interface{}for i := 0; i < len(body.Properties); i++ {    log.Println(body.Properties[i])    currentCondition := bson.M{"properties": bson.M{"$elemMatch": bson.M{"propertyName": body.Properties[i].PropertyName, "propertyValue": body.Properties[i].PropertyValue}}}    AndQuery = append(AndQuery, currentCondition)}

然后我的查询看起来像-

c.Find(bson.M{"brandId": body.BrandID, "category": body.Category, "$and": AndQuery})
