Functions

func DownloadHTTPFile

func DownloadHTTPFile(url string, saveTo string, timeoutMSec int) (int64, error)

获取http文件保存至本地

func GetHTTPFile

func GetHTTPFile(url string, timeoutMSec int) ([]byte, error)

获取http文件保存至字节切片

func ParseHTTPRequestLine

func ParseHTTPRequestLine(line string) (method string, uri string, version string, err error)

Request-Line = Method SP URI SP Version CRLF

func ParseHTTPStatusLine

func ParseHTTPStatusLine(line string) (version string, statusCode string, reason string, err error)

Status-Line = Version SP Status-Code SP Reason CRLF

func PostJson

func PostJson(url string, info interface{}, client *http.Client) (*http.Response, error)

url 地址 info 需要序列化的结构体 client 注意，如果为nil，则使用http.DefaultClient

func ReadHTTPHeader

func ReadHTTPHeader(r LineReader) (firstLine string, headers map[string]string, err error)

@return firstLine: request的request line或response的status line @return headers: request header fileds的键值对

func UnmarshalRequestJsonBody

func UnmarshalRequestJsonBody(r *http.Request, info interface{}, keyFieldList ...string) error

@brief 从http请求中解析body中的json字符串，并反序列化至结构体中

r http请求对象 info 输出参数，用于接收反序列化之后的数据 keyFieldList 可选参数，可指定一个或多个json中必须存在的字段

Types

type HTTPMsgCtx

type HTTPMsgCtx struct {
	ReqMethodOrRespVersion string
	ReqURIOrRespStatusCode string
	ReqVersionOrRespReason string
	Headers                map[string]string
	Body                   []byte
}

func ReadHTTPMessage

func ReadHTTPMessage(r HTTPReader) (ctx HTTPMsgCtx, err error)

注意，如果HTTP Header中不包含`Content-Length`，则不会读取HTTP Body，并且err返回值为nil

type HTTPReader

type HTTPReader interface {
	LineReader
	io.Reader
}

e.g. bufio.Reader

type HTTPReqMsgCtx

type HTTPReqMsgCtx struct {
	Method  string
	URI     string
	Version string
	Headers map[string]string
	Body    []byte
}

func ReadHTTPRequestMessage

func ReadHTTPRequestMessage(r HTTPReader) (ctx HTTPReqMsgCtx, err error)

type HTTPRespMsgCtx

type HTTPRespMsgCtx struct {
	Version    string
	StatusCode string
	Reason     string
	Headers    map[string]string
	Body       []byte
}

func ReadHTTPResponseMessage

func ReadHTTPResponseMessage(r HTTPReader) (ctx HTTPRespMsgCtx, err error)

type LineReader

type LineReader interface {
	ReadLine() (line []byte, isPrefix bool, err error)
}
