英文:
How to print the result one by one from an array in golang?
问题
在这段代码中，我正在根据电子邮件和密码查找数据。但是我想做另一件事，就是使用一个for循环并逐个打印result数组中的数据。
给定的结果
找到一个文档: {Name:bilal Email:bilal@gmail.com Password:bilalo Business:computer company}
期望的结果
Name:bilal
Email:bilal@gmail.com
Password:1234
Business:computer company
代码
// 根据电子邮件和密码在数据库中查找数据
var result Store
collection := client.Database("PMS").Collection("dataStored")
if err = collection.FindOne(context.TODO(), bson.M{"email": myEmail, "password": myPassword}).Decode(&result); err != nil {
log.Fatal(err)
}
fmt.Printf("找到一个文档: %+v\n", result)
for _, results := range result {
fmt.Println(results)
}
英文:
In this code, I am finding the data based on email and password. But I want to do another thing that is to use a for loop and print the result array data one by one.
Given result
Found a single document: {Name:bilal Email:bilal@gmail.com Password:bilalo Business:computer company}
Expected result
Name:bilal
Email:bilal@gmail.com
Password:1234
Business:computer company
Code
// Find data in database based on email and password
var result Store
collection := client.Database("PMS").Collection("dataStored")
if err = collection.FindOne(context.TODO(), bson.M{"email": myEmail, "password": myPassword}).Decode(&result); err != nil {
log.Fatal(err)
}
fmt.Printf("Found a single document: %+v\n", result)
for _, results := range &result {
fmt.Println(results)
}

在循环之前尝试使用以下的printf语句：
fmt.Printf("Name:%v \nEmail:%v \nPassword:%v \nBusiness:%v \n", result.Name, result.Email, result.Password, result.Business)
英文:
Try this printf before the loop
fmt.Printf("Name:%v \nEmail:%v \nPassword:%v \nBusiness:%v \n", result.Name, result.Email, result.Password, result.Business)
