我正在尝试使用 volley 在我的 android 应用程序中添加 Oauth1 授权
在邮递员中，当我添加 oauth_consumer_key、oauth_consumer_secret、token_key token_secret 等详细信息时，如下图所示
它会生成如下图所示的标题并成功收到响应。
邮递员生成的标头
Authorization:OAuth oauth_consumer_key="4e77abaec9b6fcda9kjgkjgh44c2e1",oauth_token="2da9439r34104293b1gfhse2feaffca9a1",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1482470443",oauth_nonce="cCbH5b",oauth_version="1.0",oauth_signature="A1QPwTATVF4x3cN0%2FN46CZrtSKw%3D"
问题
我搜索了很多以创建 oauth 签名，例如创建 postmasn 以附加 volley ServerConnectionChannel 但失败了。oauth_signature="A1QPwTATVF4x3cN0%2FN46CZrtSKw%3D"
当前代码
public void doSendJsonRequest(final ERequest ERequest) {
requestMethod = String.valueOf(ERequest.method);
requestUrl = String.valueOf(ERequest.mReqUrl);
if(requestMethod.equals(Request.Method.GET)){
requestMethod = "GET";
}else if(requestMethod.equals(Request.Method.POST)){
requestMethod = "POST";
}else if(requestMethod.equals(Request.Method.PUT)){
requestMethod = "PUT";
}else if(requestMethod.equals(Request.Method.DELETE)){
requestMethod = "DELETE";
}
Long tsLong = System.currentTimeMillis()/1000;
final String ts = tsLong.toString();
final String kk = requestMethod+"&" + encode(requestUrl)+"&";
final String kk = encode("GET"+"&"
+ requestUrl+"&"
+ OAUTH_CONSUMER_KEY + "=\"4e77abaec9b6fcda9b11e89a9744c2e1\"&"

RequestQueue queue = VolleyUtils.getRequestQueue();
try {
JSONObject jsonObject = ERequest.jsonObject;
EJsonRequest myReq = new EJsonRequest(ERequest.method, ERequest.mReqUrl, jsonObject, createReqSuccessListener(ERequest), createReqErrorListener(ERequest)) {
public Map < String, String > getHeaders() throws AuthFailureError {
// Long tsLong = System.currentTimeMillis()/1000;
// String ts = tsLong.toString();
String strHmacSha1 = "";
String oauthStr = "";
strHmacSha1 = generateSignature(kk, oAuthConsumerSecret, oAuthTokenSecret);
strHmacSha1 = toSHA1(strHmacSha1.getBytes());
Log.e("SHA !",strHmacSha1);
oauthStr ="OAuth "+ OAUTH_CONSUMER_KEY + "=\"4e77abaec9b6fcda9b11e89a9744c2e1\","

Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
params.put("Authorization",oauthStr);
// params.put("Authorization",getConsumer().toString());
return params;
}
};
myReq.setRetryPolicy(new DefaultRetryPolicy(
DefaultRetryPolicy.DEFAULT_TIMEOUT_MS * 4,
BABTAIN_MAX_RETRIES,
BABTAIN_BACKOFF_MULT));
myReq.setHeader("Cache-Control", "no-cache");
//myReq.setHeader("Content-Type", "application/json");
queue.add(myReq);
} catch (Exception e) {
e.printStackTrace();
}
private String generateSignature(String signatueBaseStr, String oAuthConsumerSecret, String oAuthTokenSecret) {
byte[] byteHMAC = null;
try {
Mac mac = Mac.getInstance("HmacSHA1");
SecretKeySpec spec;
if (null == oAuthTokenSecret) {
String signingKey = encode(oAuthConsumerSecret) + '&';
spec = new SecretKeySpec(signingKey.getBytes(), "HmacSHA1");
} else {
String signingKey = encode(oAuthConsumerSecret) + '&' + encode(oAuthTokenSecret);
spec = new SecretKeySpec(signingKey.getBytes(), "HmacSHA1");
}
mac.init(spec);
byteHMAC = mac.doFinal(signatueBaseStr.getBytes());
} catch (Exception e) {
e.printStackTrace();
}
String base64 = Base64.encodeToString(byteHMAC, Base64.DEFAULT);
return base64.trim();
}
private String toSHA1(byte[] convertme) {
MessageDigest md = null;
try {
md = MessageDigest.getInstance("SHA-1");
}
catch(NoSuchAlgorithmException e) {
e.printStackTrace();
}
return byteArrayToHexString(md.digest(convertme));
}
private String byteArrayToHexString(byte[] b) {
String result = "";
for (int i=0; i < b.length; i++)
result += Integer.toString( ( b[i] & 0xff ) + 0x100, 16).substring( 1 );
return result;
}
此代码创建一个签名，如 :oauth_signature="42a611860e29e893a435b555e7a9559a704f4e94" 并且未能获得授权。
收到类似错误：BasicNetwork.performRequest: url 的意外响应代码 401
？如何生成像邮递员一样使用 volley 提供的 oauth_signature
？我们如何在 volley 中添加 oauth1 签名..
请帮忙..谢谢
