我正在尝试在我的 android 应用程序中使用 REST api 在推文中上传视频。尝试使用 INIT 命令初始化上传文件会话时，我得到
代码：215，消息：错误的身份验证数据。
但是，身份验证工作正常，因为我只能使用 StatusesService 发送短信。这是代码 -
public class MainActivity extends AppCompatActivity {
public static final String consumerKey = "...";
public static final String consumerSecret = "...";
private static final String uploadEndpoint = "https://upload.twitter.com/1.1/media/upload.json";
public TwitterLoginButton loginButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TwitterAuthConfig twitterAuthConfig = new TwitterAuthConfig(MainActivity.consumerKey, MainActivity.consumerSecret);
TwitterConfig config = new TwitterConfig.Builder(this)
.logger(new DefaultLogger(Log.DEBUG))
.twitterAuthConfig(twitterAuthConfig)
.debug(true)
.build();
Twitter.initialize(config);
loginButton = (TwitterLoginButton) findViewById(R.id.login_button);
loginButton.setCallback(new Callback<TwitterSession>() {
@Override
public void success(Result<TwitterSession> result) {
long sizeOfVideoInBytes = (new File(...)).length();
HashMap<String, String> postParams = new HashMap<>();
postParams.put("command", "INIT");
postParams.put("media_type", "video/mp4");
postParams.put("media_category", "tweet_video");
postParams.put("total_bytes", String.valueOf(sizeOfVideoInBytes));
TwitterSession session = TwitterCore.getInstance().getSessionManager().getActiveSession();
TwitterAuthToken authToken = session.getAuthToken();
String token = authToken.token;
String secret = authToken.secret;
HttpsURLConnection request = initTwitterApiRequest(uploadEndpoint, "POST", postParams, token, secret);
enableStrictMode();
try {
InputStream connectionInputStream;
int responseCode = request.getResponseCode();
if (responseCode < 400)
connectionInputStream = request.getInputStream();
else
connectionInputStream = request.getErrorStream();
StringBuffer response = new StringBuffer();
if(connectionInputStream != null) {
BufferedReader in = new BufferedReader(new InputStreamReader(connectionInputStream));
String inputLine;
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
}
Map<String, List<String>> map = request.getHeaderFields();
JSONObject headerJSON = new JSONObject();
if(map != null) {
for (Map.Entry<String, List<String>> entry : map.entrySet()) {
String key = entry.getKey();
String value = entry.getValue().get(0);
if(key == null) {
key = UUID.randomUUID().toString();
}
headerJSON.put(key, value);
}
}
String responseResult = "{'code':" + String.valueOf(request.getResponseCode());
if (!response.toString().equals("")) {
responseResult = responseResult + ",'data':" + response.toString();
}
if(headerJSON.length() > 0) {
responseResult = responseResult + ",'headers':" + headerJSON.toString();
}
responseResult = responseResult + "}";
request.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void failure(TwitterException exception) {
exception.printStackTrace();
}
});
}
public void enableStrictMode()
{
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
loginButton.onActivityResult(requestCode, resultCode, data);
}
private HttpsURLConnection initTwitterApiRequest(String url, String method, HashMap<String, String> postParams,
String token, String secret) {
try {
String paramString = "";
for (Map.Entry<String, String> entry : postParams.entrySet()) {
paramString = paramString + URLEncoder.encode(entry.getKey(), "UTF-8") + "=" + URLEncoder.encode(entry.getValue(), "UTF-8") + "&";
}
String requestUrl = url;
if(!paramString.isEmpty()) {
paramString = paramString.substring(0, paramString.length() - 1);
requestUrl = requestUrl + "?" + paramString;
}
URL httpsUrl = new URL(requestUrl);
HttpsURLConnection connection = (HttpsURLConnection) httpsUrl.openConnection();
connection.setRequestMethod(method);
TwitterAuthToken twitterAuthToken = new TwitterAuthToken(token, secret);
TwitterAuthConfig twitterAuthConfig = new TwitterAuthConfig(consumerKey, consumerSecret);
OAuthSigning oAuthSigning = new OAuthSigning(twitterAuthConfig, twitterAuthToken);
Map<String, String> authHeaders = oAuthSigning.getOAuthEchoHeaders(method, url, postParams);
for(Map.Entry<String, String> entry : authHeaders.entrySet()) {
connection.setRequestProperty(entry.getKey(), entry.getValue());
}
return connection;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
我错过了什么吗？我该如何解决这个问题？
