如何从Google Apps脚本的computeHmacSha256Signature方法获取十六进制值?(How to get Hex value from computeHmacSha256Signature method of Google Apps Script?)

我阅读下面的MD5解决方案,但我无法完全理解。
从computeDigest(algorithm,value)byte []返回字符串表示形式

我想用HMAC-SHA256哈希创建API签名。

var date = new Date();
var nonce = Math.floor(date.getTime()/1000);
var url = "https://mysweet.com/api/accounts"
var secret = "my_secret";
var signature = Utilities.computeHmacSha256Signature(nonce+url, secret);

但它返回字节数组[42,-8,-47,-21,..],并且它不能直接用作API签名。 有没有一种简单的方法从方法中获得十六进制值? 或转换?


I read solution for MD5 below, but I could not quite get it.
get back a string representation from computeDigest(algorithm, value) byte[]

I'd like to create API signature with HMAC-SHA256 hash.

var date = new Date();
var nonce = Math.floor(date.getTime()/1000);
var url = "https://mysweet.com/api/accounts"
var secret = "my_secret";
var signature = Utilities.computeHmacSha256Signature(nonce+url, secret);

but it returns byte array [42, -8, -47, -21, ..], and it cannot be used as API signature directly. Is there a simple way to get a Hex value from the method? or conversion?

那么,错误本身是由ActionBarSherlock库引起的,你可以在这里找到GitHub中的问题: https//github.com/JakeWharton/ActionBarSherlock/issues/685

此处发布的评论是我的解决方案: https//github.com/JakeWharton/ActionBarSherlock/issues/685#issuecomment-11670533

转到ABS库项目的res / values-v14 / abs_themes.xml:然后您应该编辑前两个主题,如下所示:

<style name="Sherlock.__Theme" parent="android:Theme.Holo">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>
<style name="Sherlock.__Theme.Light" parent="android:Theme.Holo.Light">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>

另外不要忘记在你的清单中声明那些使用它的活动:

android:theme="@style/Theme.Sherlock.Light"

Well, the error itself is caused by ActionBarSherlock library, you can find the issue in GitHub here: https://github.com/JakeWharton/ActionBarSherlock/issues/685

And the comment posted here was my solution: https://github.com/JakeWharton/ActionBarSherlock/issues/685#issuecomment-11670533

Go to res/values-v14/abs_themes.xml of ABS library project: then you should edit first two themes like this:

<style name="Sherlock.__Theme" parent="android:Theme.Holo">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>
<style name="Sherlock.__Theme.Light" parent="android:Theme.Holo.Light">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>

Also dont forget to declare in your manifest for those activities which use it:

android:theme="@style/Theme.Sherlock.Light"
