参考

E:\svn\golang\pkg\mod\github.com\i!google-ink\gopay

代码实现

package gopay

import (
    "encoding/json"
    "encoding/xml"
    "errors"
    "io"
    "sort"
    "strings"
    "sync"
)

type BodyMap map[string]interface{}

var mu sync.RWMutex

// 设置参数
func (bm BodyMap) Set(key string, value interface{}) {
    mu.Lock()
    bm[key] = value
    mu.Unlock()
}

// 获取参数
func (bm BodyMap) Get(key string) string {
    if bm == nil {
        return NULL
    }
    mu.RLock()
    defer mu.RUnlock()
    value, ok := bm[key]
    if !ok {
        return NULL
    }
    v, ok := value.(string)
    if !ok {
        return convertToString(value)
    }
    return v
}

// 删除参数
func (bm BodyMap) Remove(key string) {
    mu.Lock()
    delete(bm, key)
    mu.Unlock()
}
