golang实现函数yamlToStruct(infile,outFile),将yaml文件格式化成golang的结构体 gpt:
要实现一个将YAML文件格式化成Golang结构体的函数你可以使用 yaml 和 reflect 包来处理。首先你需要使用 yaml.Unmarshal 函数将YAML文件解析为一个 map[string]interface{} 类型的数据结构。然后你可以使用递归函数来遍历这个map并生成相应的Golang结构体定义。
以下是一个简单的实现
go package main
import ( fmt io/ioutil log reflect gopkg.in/yaml.v2 )
func yamlToStruct(infile, outFile string) error { // 读取YAML文件内容 yamlData, err : ioutil.ReadFile(infile) if err ! nil { return err } // 解析YAML文件 var data map[string]interface{} if err : yaml.Unmarshal(yamlData, data); err ! nil { return err } // 生成Golang结构体定义 structCode : generateStructCode(MyStruct, data) // 将结构体定义写入文件 if err : ioutil.WriteFile(outFile, []byte(structCode), 0644); err ! nil { return err } return nil }
func generateStructCode(structName string, data map[string]interface{}) string { structCode : fmt.Sprintf(type %s struct {\n, structName) for key, value : range data { // 判断值的类型 switch v : value.(type) { case map[interface{}]interface{}: // 如果是嵌套map则递归生成结构体定义 nestedStruct : generateStructCode(toCamelCase(key.(string)), v) structCode fmt.Sprintf(\t%s %s\n, toCamelCase(key.(string)), nestedStruct) default: // 其他类型直接生成字段定义 structCode fmt.Sprintf(\t%s %s\n, toCamelCase(key.(string)), reflect.TypeOf(value).String()) } } structCode }\n return structCode }
func toCamelCase(s string) string { // 将下划线分隔的单词转换为驼峰式 result : upper : true for _, c : range s { if c _ { upper true } else { if upper { result string(c - (a - A)) upper false } else { result string(c) } } } return result }
func main() { // 替换为你的YAML文件路径和输出文件路径 infile : example.yaml outFile : output.go err : yamlToStruct(infile, outFile) if err ! nil { log.Fatal(err) } }
在这个例子中yamlToStruct 函数接受输入的YAML文件路径和输出的Golang文件路径。它首先读取YAML文件然后使用 yaml.Unmarshal 函数将其解析为一个 map[string]interface{}。接着它调用 generateStructCode 函数生成Golang结构体的定义并将生成的代码写入到输出文件中。 toCamelCase 函数用于将下划线分隔的字段名转换为驼峰式。请注意这个实现是一个简单的示例可能需要根据实际情况进行调整。 调整后的代码
package mainimport (fmtio/ioutillogreflectgopkg.in/yaml.v2
)func append(structName string) string {upName : toCamelCase(structName)data : fmt.Sprintf(var g_%s *%sfunc Get%s() *%s {if g_%s ! nil {return g_%s}yamlData, err : ioutil.ReadFile(assets/yaml/%s.yaml)if err ! nil {return nil}g_%s new(%s)if err : yaml.Unmarshal(yamlData, g_%s); err ! nil {return nil}return g_%s
}, upName, upName, upName, upName, upName, upName, structName, upName, upName, upName, upName)return data
}
func yamlToStruct(infile, outFile string, structName string) error {// 读取YAML文件内容yamlData, err : ioutil.ReadFile(infile)if err ! nil {return err}// 解析YAML文件var data map[interface{}]interface{}if err : yaml.Unmarshal(yamlData, data); err ! nil {return err}// 生成Golang结构体定义structCode : generateStructCode(toCamelCase(structName), data, 1)// 将结构体定义写入文件if err : ioutil.WriteFile(outFile, []byte(package yaml\nstructCodeappend(structName)), 0644); err ! nil {return err}return nil
}func generateStructCode(structName string, data map[interface{}]interface{}, deep int) string {structCode : fmt.Sprintf(%s struct {\n, structName)switch deep {case 1:structCode fmt.Sprintf(type %s struct {\n, structName)case 2: //数组structCode fmt.Sprintf(struct{\n)default:}for key, value : range data {// Check if key is a stringkeyStr, ok : key.(string)if !ok {// Handle the case where key is not a string (e.g., if YAML has non-string keys)log.Printf(Skipping key %v of non-string type\n, key)continue}// Determine the type of the valueswitch v : value.(type) {case []interface{}:// If its an array, check if its headersif len(v) 0 {// Check if the first element is a mapif headerMap, ok : v[0].(map[interface{}]interface{}); ok {// If its headers, generate struct code for Header typeheaderStruct : generateStructCode(toCamelCase(keyStr), headerMap, 2)structCode fmt.Sprintf(\t%s []%s yaml:\%s\\n, toCamelCase(keyStr), headerStruct, keyStr)continue}if _, ok : v[0].(string); ok {// If its headers, generate struct code for Header typestructCode fmt.Sprintf(\t%s []%s yaml:\%s\\n, toCamelCase(keyStr), string, keyStr)continue}}// If its a regular array, generate struct code for its elementsnestedStruct : generateStructCode(toCamelCase(keyStr), v[0].(map[interface{}]interface{}), 2)structCode fmt.Sprintf(\t%s []%s yaml:\%s\\n, toCamelCase(keyStr), nestedStruct, keyStr)case map[interface{}]interface{}:// If its a nested map, recursively generate struct codenestedStruct : generateStructCode(toCamelCase(keyStr), v, 0)//structCode fmt.Sprintf(\t%s %s yaml:\%s\\n, toCamelCase(keyStr), nestedStruct, keyStr)structCode fmt.Sprintf(\t%s yaml:\%s\\n, nestedStruct, keyStr)default:// For other types, generate field definition with yaml tagstructCode fmt.Sprintf(\t%s %s yaml:\%s\\n, toCamelCase(keyStr), reflect.TypeOf(value).String(), keyStr)}}structCode }return structCode
