Meteor 调用 api 导致重复输入

Question

我使用 Loopback 作为后端 api 服务器到我的数据库，使用 Meteor 作为前端。在 Meteor 中，我使用 Axios 来调用 api。

我想使用 Meteor.call 以便我可以在同一个文件中管理所有相关的 api 调用函数，以便于管理，例如invoice 获取、添加、编辑、删除所有发票文件等

如果我在表单提交时直接调用 Axios 发布到 API，我的数据库中的记录只显示插入的一条记录（这是预期的）。但是，如果我从 Meteor.call 中调用 Axios，它将导致数据库具有相同上下文的双重条目。

我不太明白重复输入的原因或来源。谁能解释一下？

谢谢。

我的 Meteor 方法调用 api 来插入一个新的 textContext：

Meteor.methods({
    'textContext.insert': function(myText, token) {
        new SimpleSchema({
            myText: {
                type: String,
                min: 1
            },
            token: {
                type: String,
                label: 'Authorization',
                min: 1
            }
        }).validate({myText, token});

        const jsonToken = JSON.parse(token);
        const url = `http://localhost:3001/v1/users/${jsonToken.userId}/textContexts`;
        const data = {
            text_context: myText,
            user_id: jsonToken.userId
        };

        return axios({
            method: 'post',
            url,
            headers: {'Authorization': jsonToken.token},
            data
        })
        .then(res => {
            console.log(res.data);
            return res.data;
        })
        .catch((err) => {
            if (err instanceof Error) {
                console.log('Error:', err.message);
            }
        });
    }
});

Loopback 中的TextContext 模型，text-context.json，从 textContextBasic 扩展而来，只包含一个 created_at：

{
  "name": "textContext",
  "base": "textContextBasic",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "text_context": {
      "type": "string"
    }
  },
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "user_id"
    }
  },
  "acls": [
    {
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "DENY"
    },
    {
      "accessType": "EXECUTE",
      "principalType": "ROLE",
      "principalId": "$authenticated",
      "permission": "ALLOW",
      "property": "create"
    },
    {
      "accessType": "EXECUTE",
      "principalType": "ROLE",
      "principalId": "$authenticated",
      "permission": "ALLOW",
      "property": "createOrReplace"
    },
    {
      "accessType": "EXECUTE",
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "findById"
    },
    {
      "accessType": "READ",
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "findOne"
    },
    {
      "accessType": "EXECUTE",
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "find"
    }
  ],
  "methods": {}
}

Loopback 中的 User.json 模型：

{
  "name": "user",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "created_at": {
      "type": "date",
      "required": true,
      "default": "$now"
    },
    "updated_at": {
      "type": "date",
      "required": true,
      "default": "$now"
    }
  },
  "validations": [],
  "relations": {
    "textContexts": {
      "type": "hasMany",
      "model": "textContext",
      "foreignKey": "user_id"
    }
  },
  "acls": [
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "DENY"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "admin",
      "permission": "ALLOW"
    },
    {
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "__get__textContext"
    },
    {
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "__create__textContext"
    },
    {
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "__findById__textContext"
    },
    {
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW",
      "property": "__updateById__textContext"
    }
  ],
  "methods": {}
}

终于找到问题的根源了，因为是在客户端，所以需要用(Meteor.isServer)括起来。
