func GenRandomStr

func GenRandomStr(length int) string

func Int64ToStr

func Int64ToStr(i int64) string

func LoadFile

func LoadFile(fileFullPath string) []byte

func PKCS7UnPadding

func PKCS7UnPadding(plantText []byte) ([]byte, error)

PKCS7UnPadding return unpadding []Byte plantText

func ParseZoneTime

func ParseZoneTime(input string) (time.Time, error)

func RandStr

func RandStr(length int) string

gen random string. 问题：数字部分过多

func StrToInt64

func StrToInt64(str string) (int64, error)

func VerifyCallback

func VerifyCallback(w http.ResponseWriter, r *http.Request) bool

客户端直传后，OSS的回调函数中调用该函数进行参数验证。这里都把返回值写入了http.ResponseWriter中

Types

type CallbackParam

type CallbackParam struct {
	CallbackUrl      string `json:"callbackUrl"`
	CallbackBody     string `json:"callbackBody"`
	CallbackBodyType string `json:"callbackBodyType"`
}

type ConfigStruct

type ConfigStruct struct {
	Expiration string     `json:"expiration"`
	Conditions [][]string `json:"conditions"`
}

type DataBox

type DataBox struct {
	// contains filtered or unexported fields
}

func NewDataBox

func NewDataBox(data interface{}) *DataBox

功能：生成NewDataBox对象，以便向data(必须是slice)中的成员(slice中的成员)添加指定数据，数据由FetchObjsByKeysRetMapFunc或者 FetchObjsByKeysRetSliceFunc返回slice中的对象和map中的value可以是结构或者是结构的指针 keyFieldName指明后续获取数据的key，后续会收集所有的key，传到FetchObjs...函数，以便集中化获取数据，提升效率 通过SaveToField函数指明的fieldname，得到数据填充的位置 其它特点： 1. 可以回填对象或者对象Slice 2. 可以多重填充 3. 被填充对象为指针，填充对象为结构对象 这种情况会导致异常

func (*DataBox) JoinByMap

func (d *DataBox) JoinByMap(f FetchObjsByKeysRetMapFunc) *DataBox

func (*DataBox) KeyField

func (d *DataBox) KeyField(keyFieldName string) *DataBox

func (*DataBox) SaveToField

func (d *DataBox) SaveToField(fieldName string) error

type EscapeError

type EscapeError string

func (EscapeError) Error

func (e EscapeError) Error() string

type FetchObjsByKeysRetMapFunc

type FetchObjsByKeysRetMapFunc func(keyList interface{}) (key2ObjsMap interface{}) // map[key][]obj  or  map[key]obj  or map[key][]*obj  or  map[key]*obj

用户需要实现的函数：通过key列表来获取对象，用于JoinByMap key列表时data里面通过keyfield抽取的key列表 第一个返回的map的key为传入的key；map里面的value可以是查到的单个对象，也可以是一个可以对应的对象slice 与FetchObjsByKeysRetSliceFunc相比，性能更高，且子结构可以不带父对象的ID，缺点是需要多写点代码

type InvalidHostError

type InvalidHostError string

func (InvalidHostError) Error

func (e InvalidHostError) Error() string

type OssBucket

type OssBucket struct {
	// contains filtered or unexported fields
}

func InitOssBucket

func InitOssBucket(endPoint, accessKeyID, accessKeySecret, bucketName string, clientCacheTime int, callbackUrl, uploadDir string, tokenExpireTime int64) (*OssBucket, error)

endPoint, accessKeyID, accessKeySecret, bucketName string, clientCacheTime 为基础配置 callbackUrl uploadDir tokenExpireTime为客户端上传时的配置，callbackUrl为上传到oss的回调地址，uploadDir为上传的目录，tokenExpireTime为临时token的过期时间

func (*OssBucket) DeleteOssRes

func (bucket *OssBucket) DeleteOssRes(resourcePath string) bool

func (*OssBucket) GetPolicyToken

func (bucket *OssBucket) GetPolicyToken(tokenExpireTime int64) string

获取客户端直传签名 客户端直传文档：https://help.aliyun.com/document_detail/31925.html， go demo：https://help.aliyun.com/document_detail/91818.html?spm=a2c4g.11186623.2.18.6ff36e28eGmN06#concept-mhj-zzt-2fb

func (bucket *OssBucket) SetOption(resourcePath string, option *OssOption) bool

func (*OssBucket) UploadToOss

func (bucket *OssBucket) UploadToOss(resourcePath string, contentType string, reader io.Reader) bool

服务器端直传

type OssOption struct {
	ContentType string
	ClientCache string /*max-age=300*/
	Origin      string

	Signature   string `json:"signature"`
	Policy      string `json:"policy"`
	Directory   string `json:"dir"`
	Callback    string `json:"callback"`
}

type WxBizDataCrypt

type WxBizDataCrypt struct {
	AppID      string
	SessionKey string
}
