我正在尝试将数据从 DB ( Mongo ) 映射到 slice in go ，如果我返回简单的 []string 一切正常，但如果我将类型更改为 [ ]*models.Organization 代码返回相同元素的 slice 。

func (os *OrganizationService) GetAll() ([]*models.Organization, error) { 
    var organizations []*models.Organization 
    results := os.MongoClient.Collection("organizations").Find(bson.M{}) 
    organization := &models.Organization{} 
    for results.Next(organization) { 
        fmt.Println(organization) 
        organizations = append(organizations, organization) 
    } 
    return organizations, nil 
} 
 
 

我期望输出 [{ Name: "someOrg", ID: "someId"},{ Name: "someOrg2", ID: "someID }, ... ] ，但实际输出是[{ 名称:“someOrg”，ID:“someId”}，{名称:“someOrg”，ID:“someId”}，...]

我正在使用 bongo 包。

请您参考如下方法:

应用程序在循环的每次迭代中附加相同的 organization 值。通过在循环内创建一个新值来修复。

func (os *OrganizationService) GetAll() ([]*models.Organization, error) { 
    var organizations []*models.Organization 
    results := os.MongoClient.Collection("organizations").Find(bson.M{}) 
    organization := &models.Organization{} 
    for results.Next(organization) { 
        fmt.Println(organization) 
        organizations = append(organizations, organization) 
        organization = &models.Organization{} // new value for next iteration 
    } 
    return organizations, nil 
}
