我是一名 Android 开发人员，是 Woocommerce 的新手，并开始使用 Oauth1.0 身份验证来使用 REST 服务。当我从我的 android 应用程序调用时，我得到了 PostMan（RestClient 插件）的正确响应并得到“无效签名”错误。
这是我的安卓代码：
OAuthParameters oauth;
public OAuthParameters authChecking() {
oauth = new OAuthParameters();
GenericUrl genericUrl = new GenericUrl("http://localhost/wordpress/wc-api/v3/products/count");
oauth.consumerKey = "ck_xxxxxxxxxxxxxxxxxxxxxxxxxxx";
oauth.signatureMethod = "HMAC-SHA1";
oauth.version = "3.0";
oauth.computeTimestamp();
oauth.computeNonce();
oauth.signer = new OAuthSigner() {
@Override
public String getSignatureMethod() {
return oauth.signatureMethod;
}
@Override
public String computeSignature(String signatureBaseString) throws GeneralSecurityException {
String key = "cs_xxxxxxxxxxxxxxxxxxxxxxxxxx";
Mac mac = Mac.getInstance(
"HmacSHA1");
SecretKeySpec secret = new SecretKeySpec(key.getBytes(), "HmacSHA1");
mac.init(secret);
byte[] digest = mac.doFinal(signatureBaseString.getBytes());
Log.e("SIGNATURE Base64", new String(Base64.encode(digest, 0)).trim());
String signature = new String(com.google.api.client.repackaged.org.apache.commons.codec.binary.Base64.encodeBase64String(digest));
return signature;
}
};
try {
oauth.computeSignature("GET", genericUrl);
} catch (GeneralSecurityException e) {
e.printStackTrace();
return null;
} catch (NullPointerException e) {
e.printStackTrace();
return null;
}
methodSignatureTest();
return oauth;
}
@Override
public void requestAPI(Object... param) {
OAuthParameters oauth = authChecking();
if (oauth != null) {
String url = null;
try {
Toast.makeText(MainActivity.this, "Signature retrive called", Toast.LENGTH_SHORT).show();
url = "http://localhost/wordpress/wc-api/v3/products/"+"count?oauth_consumer_key=" + oauth.consumerKey + "&oauth_signature_method=" + oauth.signatureMethod + "&oauth_timestamp=" + oauth.timestamp + "&oauth_nonce=" + oauth.nonce + "&oauth_version=" + oauth.version + "&oauth_signature="
// + java.net.URLDecoder.decode(oauth.signature, "UTF-8");
+ URLEncoder.encode(oauth.signature, "UTF-8");
// +oauth.signature;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
url = null;
}
Log.v("URL ", url);
Log.v("SINGNATURE ", oauth.signature);
getDataFromWeb_Get.getData(this, this, new String[]{"http://localhost/wordpress/wc-api/v3/products/", url});
}
}
我在谷歌上搜索了生成签名，但所有人都在说相同的代码。我使用此工具http://oauth.googlecode.com/svn/code/javascript/example/signature.html验证签名但无法验证，因为 PostMan、此工具和 android 生成的签名彼此不同。
