Question

当我测试我的graphql突变时，我遇到一个问题，它表明我确实传递了错误的参数

这是我要在graphiql中做的事情

mutation{
  sendMessage(senderId:"sender" receiverId:"receiver" messageText:"some text in here"){
    messageText
  }
}

typeDefs

...
type Mutation{
....
    sendMessage( senderId: String!, receiverId: String!, messageText: String! ): Message
}

resolvers.js

Mutation:{
        sendMessage: async (root, { senderId, receiverId, messageText }, { User, Message }) => {
            const newMessage = await new Message(senderId, receiverId, messageText).save();
            return newMessage;
        },
}

消息模型

const mongoose = require("mongoose");

const Schema = mongoose.Schema;

const MessageSchema = new Schema({
    senderId: {
        type: String,
        required: true,
    },
    receiverId: {
        type: String,
        required: true
    },
    messageText: {
        type: String,
        required: true
    }
});

module.exports = mongoose.model("Message", MessageSchema);

我希望成为some text in here

问题是我没有传递物体；

sendMessage: async (root, { senderId, receiverId, messageText }, { User, Message }) => {
            const newMessage = await new Message({senderId, receiverId, messageText}).save();
            return newMessage;
        },

Graphql的Document（）的参数\“ obj \”必须是一个对象，得到了`
