Node.js POST请求不仅发送对象，还发送对象数组

如何解决Node.js POST请求不仅发送对象，还发送对象数组

如您在图片中看到的，它什么也没保存。 POST请求正在运行，但是我发送给后端的数据仅保存具有ID的新对象，而不保存我提供的数据，我的意思是对象数组。

我没有任何错误，或者状态还可以。我正在与邮递员测试。 这是邮递员的发帖请求

我将添加一些代码。

这是模型。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#define MAX_WORD_LEN 1024


/**
 * Note: this could also handle if spaces are the end
 *
*/


int main() {
    char* text = "some text  ";    
    char* text2 = malloc(sizeof(char) * MAX_WORD_LEN); // note: sizeof(char),cause string

    char *itr = text; // its better to put a seperate iterator to iterate over strings in c
    char *itr2 = text2; // declare a iterator to iterate over text2

    while (*itr != '\0') {
          *itr2 = *itr;

          // increase both iterator
          itr++;
          itr2++;

          // there's no need to provide a if here,just run while loop
          // also notice,previously by increasing "text" pointer you may reach the end
          // but,you're not checking it
          // but,you should check it
          while(*itr != '\0' && isspace(*itr)){ 
              itr++; // while iterating 
          }
     
          // there's no need to increase "itr" here
    }

    // finally at a null char to the end of text2
    *itr2 = '\0';

    printf("text: %s\n\n",text);
    printf("text2: %s\n",text2);

    // at last free allocated memory
    free(text2);

    return 0;
}

这是控制器。

    const mongoose = require("mongoose");
    
    const dataModelScheme = new mongoose.Schema({
        _id: mongoose.Schema.Types.ObjectId,personalData: [{
            _id: mongoose.Schema.Types.ObjectId,title: String,firstName: String,lastName: String,email: String,birthday: String,telephone: Number,driveLicense: String,status: Number,employmentType: String,job: String,}],career: [{
            _id: mongoose.Schema.Types.ObjectId,name: String,startDate: Number,endDate: Number,description: String,education: [{
            _id: mongoose.Schema.Types.ObjectId,description: String
        }],skills: [{
            _id: mongoose.Schema.Types.ObjectId,user: {
            type: mongoose.Schema.Types.ObjectId,ref: "User"
        },});
    module.exports = mongoose.model('ModelSchema',dataModelScheme);

解决方法

您正在发送对象数组，但是尝试使用点符号将它们读取为对象。您需要通过在方括号中提供索引来将它们读取为数组。我不会介绍您的所有资产，但这是您需要做的要点。

  const modelData = new ModelData({
        _id: new mongoose.Types.ObjectId(),user: user_id,personalData: [{
            _id: new mongoose.Types.ObjectId(),title: req.body.personalData[0].title,firstName: req.body.personalData[0].firstName,lastName: req.body.personalData[0].lastName,// DO similar for the rest of your properties
        }],

这是因为在创建模型时，您仅传递了一个用于PersonalData，技能和教育的元素。试试这样的东西

const modelData = new ModelData({
            _id: new mongoose.Types.ObjectId(),personalData: req.body.personalData.map(personalData => {
                return {
                    _id: new mongoose.Types.ObjectId(),title: personalData.title,firstName: personalData.firstName,lastName: personalData.lastName,email: personalData.email,birthday: personalData.birthday,telephone: personalData.telephone,driveLicense: personalData.driveLicense,status: personalData.status,employmentType: personalData.employmentType,job: personalData.job
                };
            }),skills: req.body.skills.map(skill => {
                return {
                    _id: new mongoose.Types.ObjectId(),name: skill.name,description: skill.description
                };
            },education: req.body.education.map(education => {
                return {
                    _id: new mongoose.Types.ObjectId(),name: education.name,description: education.description
                };
            }
        });
