我正在尝试使用组合 API 在 Vue 3 组件中输入提示我的道具。

所以，我这样做：

<script lang="ts">
import FlashInterface from '@/interfaces/FlashInterface';
import { ref } from 'vue';
import { useStore } from 'vuex';

export default {
    props: {
        message: {
            type: FlashInterface,
            required: true
        }
    },
    setup(props): Record<string, unknown> {
            // Stuff
        }
};

我的FlashInterface看起来像这样：

export default interface FlashInterface {
    level: string,
    message: string,
    id?: string
}

除了在这种情况下我收到此错误外，此界面运行良好：

ERROR in src/components/Flash.vue:20:10
TS2693: 'FlashInterface' only refers to a type, but is being used as a value here. …

我正在使用Python在本地ElasticSearch（localhost：9200）中添加条目

目前，我使用这种方法：

def insertintoes(data):
"""
Insert data into ElasicSearch
:param data: dict
:return:
"""
timestamp = data.get('@timestamp')
logstashIndex = 'logstash-' + timestamp.strftime("%Y.%m.%d")
es = Elasticsearch()
if not es.indices.exists(logstashIndex):
    # Setting mappings for index
    mapping = '''
        {
            "mappings": {
                  "_default_": {
                    "_all": {
                      "enabled": true,
                      "norms": false
                    },
                    "dynamic_templates": [
                      {
                        "message_field": {
                          "path_match": "message",
                          "match_mapping_type": "string",
                          "mapping": {
                            "norms": false,
                            "type": "text"
                          }
                        }
                      },
                      {
                        "string_fields": {
                          "match": "*",
                          "match_mapping_type": "string",
                          "mapping": {
                            "fields": {
                              "keyword": {
                                "type": …

我有这个关联数组:

lettres['A']=0
…(from 'A' to 'Z')…
lettres['Z']=0

我的问题很简单:如何获取一个元素的值并递增它？我尝试过以下方法:

lettres[$char]=${lettres[$char]}++

但它失败了,因为结果是«0 ++++++++.我怎样才能轻松增加价值？

编辑:更多代码:

while (( i++ < ${#word} )); do
    #$char current char
    char=$(expr substr "$word" $i 1)
    if [[ "${mot[@]}" =~ "${char} " || "${mot[${#mot[@]}-1]}" == "${char}" ]]; then
        #char is currently in array $mot -> skipping
        echo 'SKIPPING'
    else
        #Char is not in array $mot -> adding + incrementing lettres
        ((lettres[char]++))
        echo ${lettres[$char]}
        #Adding to $mot
        mot[${#mot[@]}]=$char
    fi
    echo "<$char>"
done
