php、go、python后端接口签名实现

php实现

function makeSignature($args, $key){    if(isset($args['sign'])) {        $oldSign = $args['sign'];        unset($args['sign']);    } else {        $oldSign = '';    }    ksort($args);    $requestString = '';    foreach($args as $k => $v) {        $requestString .= $k . '=' . urlencode($v);    }    $newSign = hash_hmac("sha256",strtolower($requestString) , $key);    return $newSign;}

golang 实现

package mainimport (    "crypto/sha1"    "crypto/hmac""crypto/sha256"    "encoding/hex"    "fmt"    "sort"    "strconv"    "time")func makeSign(params, key) {    var dataParams string    //ksort    var keys []string    for k := range params {        keys = append(keys, k)    }    sort.Strings(keys)    //拼接    for _, k := range keys {        fmt.Println("key:", k, "Value:", params[k])        dataParams = dataParams + k + "=" + params[k] + "&"    }    fmt.Println(dataParams)    ff := dataParams[0 : len(dataParams)-1]    fmt.Println("去掉最后一个&：", ff)    //对字符串进行hmac哈希    h := hmac.New(sha256.New, key)    h.Write([]byte(dataParams))    bs := h.Sum(nil)    sign := hex.EncodeToString(bs)    //拼接请求参数    dataPost := dataParams + "&sign" + "=" + sign    return dataPost}

python实现

from hashlib import sha256import urllibimport hmacdef urlencode(val):    return urllib.parse.quote(val, safe='/', encoding=None, errors=None)def ksort(d):    '''遍历字典转成list'''    return [(k,urlencode(d[k])) for k in sorted(d.keys())]def makeSign(params, key):    dd = ksort(params)    data = "&".join(["=".join(i) for i in dd if i[1] and i[0] != "sign"])    return hmac.new(key.encode('utf-8'), data.encode('utf-8'), digestmod=sha256).hexdigest().upper()
