如何在Moleculer中获取请求正文

Question

根据API文档，要从POST请求接收json作为formData，必须使用主体解析器。我已经在网关服务中声明了它，但是我仍然无法在我的操作中接收到formData。

api.service.js

module.exports = {
 name: "api",
 mixins: [ApiGateway],

 settings: {
    port: process.env.PORT || 3000,

    routes: [{
        path: "/api",
        aliases: {
          "POST users": "users.insertUser",
        },
        //The API Documentation recomends using the body-parser here
        bodyParsers: {
            json: true,
            urlencoded: { extended: true }
        },
    }],

    // In some example they also set the body-parser here
    bodyParsers: {
        json: true,
        urlencoded: { extended: true }
    },
 },
};

在actions service.insertUser操作中，我应该以ctx.params的身份接收req.body，但它始终为空

我的users.service.js

    actions: {
    insertUser: {
        handler(ctx) {
            this.logger.info("posting", ctx.params); // -> prints {} instead of the formData
        }
    }

你有没有试过给病人

insertUser: {
            auth: "required",
            params: {
                function_id: { type: "string" },
                role_id: { type: "string" },
            },
            handler(ctx) { ctx.params.role_id
