如何使用Gorm (go struct)将值从Postman (json类型)插入Postgres

go get -u github.com/jinzhu/gorm
go get -u github.com/jinzhu/gorm/dialects/postgres

import (
    "github.com/jinzhu/gorm"
    _ "github.com/jinzhu/gorm/dialects/postgres"
)

func createConnection() (*gorm.DB, error) {
    db, err := gorm.Open("postgres", "host=your_host port=your_port user=your_user dbname=your_db password=your_password sslmode=disable")
    if err != nil {
        return nil, err
    }

    return db, nil
}

type PostmanData struct {
    gorm.Model
    Field1 string `json:"field1"`
    Field2 int    `json:"field2"`
    // 其他字段...
}

func insertData(postmanData PostmanData) error {
    db, err := createConnection()
    if err != nil {
        return err
    }
    defer db.Close()

    if err := db.AutoMigrate(&PostmanData{}).Error; err != nil {
        return err
    }

    if err := db.Create(&postmanData).Error; err != nil {
        return err
    }

    return nil
}
