Twitter OAuth Rest Api状态参数'@'符号
我正在使用twitter rest API（https://api.twitter.com/1.1/）。
首先我使用路标库来生成oauth_signature。 它运作良好。
上传状态端点（https://api.twitter.com/1.1/statuses/upload.json）运行良好，但如果状态参数包含'@'符号，则表示不起作用。 所以这是我的代码
TwitterStatusesService.java
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.POST;
import retrofit2.http.Path;
import retrofit2.http.Query;
public interface TwitterStatusesService {
@POST("/1.1/statuses/update.json")
Call<ResponseBody> update(@Query("status") String status, @Query("in_reply_to_status_id") String inReplyToStatusId, @Query("lat") Double lat, @Query("long") Double lon, @Query("media_ids") String mediaIds);
}
TwitterStatusesAPIClient.java
import android.util.Log;
import com.twitter.sdk.android.core.TwitterAuthToken;
import com.twitter.sdk.android.core.TwitterCore;
import com.twitter.sdk.android.core.TwitterSession;
import okhttp3.OkHttpClient;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.Retrofit;
import se.akerfeldt.okhttp.signpost.OkHttpOAuthConsumer;
import se.akerfeldt.okhttp.signpost.SigningInterceptor;
public class TwitterStatusesClient {
private final String TAG = getClass().getSimpleName();
private static final String BASE_URL = "https://api.twitter.com/";
private final TwitterStatusesService apiService;
private static TwitterStatusesClient webServiceClient;
public static TwitterStatusesClient getInstance() {
if (webServiceClient == null)
webServiceClient = new TwitterStatusesClient();
return webServiceClient;
}
private TwitterStatusesClient() {
private TwitterStatusesClient() {
OkHttpOAuthConsumer consumer = new OkHttpOAuthConsumer(TWITTER_KEY, TWITTER_SECRET);
TwitterSession activeSession = TwitterCore.getInstance().getSessionManager().getActiveSession();
if (activeSession != null) {
TwitterAuthToken authToken = activeSession.getAuthToken();
String token = authToken.token;
String secret = authToken.secret;
consumer.setTokenWithSecret(token, secret);
}
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new SigningInterceptor(consumer))
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.build();
apiService = retrofit.create(TwitterStatusesService.class);
}
public Call<ResponseBody> update(String status, String statusId, Double lat, Double lon, String mediaIds) {
return apiService.update(status, statusId, lat, lon, mediaIds);
}
}
调用API客户端
String status = "@example";
TwitterStatusesClient.getInstance().update(status, null, null, null, null).enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
Log.v(TAG, "onResponse");
progressDialog.dismiss();
try {
if (response.errorBody() != null) {
String error = response.errorBody().string();
Log.e(TAG, "Error : " + error);
ToastUtils.showErrorMessage(getContext(), "Error : " + error);
return;
}
String body = response.body().string();
Log.v(TAG, "body : " + body);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.v(TAG, "onFailure");
t.printStackTrace();
}
});
给出错误：
{"errors":[{"code":32,"message":"Could not authenticate you."}]}
但是，如果我将使用状态变量“只是示例”而不是“@example”（具体点是删除@字符），它正在工作。 只有'@'符号不起作用。
编辑
这是我通过retrofit拦截器手动创建OAuth v1.0a签名代码：
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request request = chain.request();
String method = request.method();
String baseUrl = "https://api.twitter.com" + request.url().url().getPath();
String oauthToken = "";
String oauthTokenSecret = "";
TwitterSession activeSession = TwitterCore.getInstance().getSessionManager().getActiveSession();
if (activeSession != null) {
TwitterAuthToken authToken = activeSession.getAuthToken();
oauthToken = authToken.token;
oauthTokenSecret = authToken.secret;
}
String oauthNonce = "TXZScw4M8TG";
String oauthSignatureMethod = "HMAC-SHA1";
String oauthTimestamp = String.valueOf(System.currentTimeMillis() / 1000);
String oauthVersion = "1.0";
String parameterString = "";
parameterString = OAuthParams.addParam(request, parameterString, "count");
parameterString = OAuthParams.addParam(request, parameterString, "id");
parameterString = OAuthParams.addParam(request, parameterString, "in_reply_to_status_id");
// if any parameter added to parameterString, append '&' character.
if (parameterString.length() > 0) {
parameterString += "&";
}
parameterString += "oauth_consumer_key=" + TWITTER_KEY + "&"
+ "oauth_nonce=" + oauthNonce + "&"
+ "oauth_signature_method=" + oauthSignatureMethod + "&"
+ "oauth_timestamp=" + oauthTimestamp + "&"
+ "oauth_token=" + oauthToken + "&"
+ "oauth_version=" + oauthVersion;
// add status parameter to parameterString.
parameterString = OAuthParams.addParam(request, parameterString, "status");
Log.d(TAG, "normalizedParameters : " + parameterString);
Log.d(TAG, "parameterStringPercent : " + OAuth.percentEncode(parameterString));
String signatureBaseString = "";
signatureBaseString += OAuth.percentEncode(method) + "&";
signatureBaseString += OAuth.percentEncode(baseUrl) + "&";
signatureBaseString += OAuth.percentEncode(parameterString);
String oauthSignature = OauthSignature.generateSignature(signatureBaseString, TWITTER_SECRET,
oauthTokenSecret);
String authorization = "OAuth oauth_consumer_key="" + TWITTER_KEY + "", " +
"oauth_signature_method="HMAC-SHA1", " +
"oauth_timestamp="" + oauthTimestamp + "", " +
"oauth_nonce="" + oauthNonce + "", " +
"oauth_version="1.0", " +
"oauth_token="" + oauthToken + "", " +
"oauth_signature="" + OAuth.percentEncode(oauthSignature) + """;
Log.w(TAG, "Authorization : " + authorization);
request = request.newBuilder()
.addHeader("Authorization", authorization)
.build();
return chain.proceed(request);
}
}).addInterceptor(interceptor).build();
OAuth.java
public static String percentEncode(String s) {
if (s == null) {
return "";
}
try {
return URLEncoder.encode(s, ENCODING)
// OAuth encodes some characters differently:
.replace("+", "%20").replace("*", "%2A")
.replace("%7E", "~");
// This could be done faster with more hand-crafted code.
} catch (UnsupportedEncodingException wow) {
throw new RuntimeException(wow.getMessage(), wow);
}
}
OAuthSignature.java
import android.util.Base64;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
public class OauthSignature {
public static String generateSignature(String signatueBaseStr, String oAuthConsumerSecret, String oAuthTokenSecret) {
byte[] byteHMAC = null;
try {
Mac mac = Mac.getInstance("HmacSHA1");
SecretKeySpec spec;
if (null == oAuthTokenSecret) {
String signingKey = OAuth.percentEncode(oAuthConsumerSecret) + '&';
spec = new SecretKeySpec(signingKey.getBytes(), "HmacSHA1");
} else {
String signingKey = OAuth.percentEncode(oAuthConsumerSecret) + '&' + OAuth.percentEncode(oAuthTokenSecret);
spec = new SecretKeySpec(signingKey.getBytes(), "HmacSHA1");
}
mac.init(spec);
byteHMAC = mac.doFinal(signatueBaseStr.getBytes());
} catch (Exception e) {
e.printStackTrace();
}
return new String(Base64.encode(byteHMAC, Base64.DEFAULT));
}
}
我建议去织物 - https://fabric.io其中有Twitter的登录，crashlytics和alss twitters各种库，你需要安装与android studio结构插件。 发布信息，无论你想发布什么，你都可以发布/检索你的推文。
对于你的问题 - 检查'@'是特殊符号，通过改造导致问题。 这些问题需要我在不同场景下面临的改造。
尝试使用面料的Twitter登录/ oAuth
您必须对网址进行编码，@ =>％40。 它工作正常，我已经尝试过（y）。
