如何调用API（Oauth 1.0）？

Question

我试图调用此API（Oauth1.0标准）：

https://appcenter.intuit.com/api/v1/Connection/Reconnect

我正在做的是:(它正在研究java）

Base64Encoder baseEncoder = Base64Encoder.getInstance();
            CloseableHttpClient httpclient = HttpClients.createDefault();
            HttpGet httpGet = new HttpGet("https://appcenter.intuit.com/api/v1/connection/reconnect");
            StringBuilder headerReq = new StringBuilder();
            headerReq.append("OAuth ");
            headerReq.append("oauth_token=\"").append(OAUTHTOKEN).append("\"");
            headerReq.append(", oauth_consumer_key=\"").append(CUNSUMER_KEY).append("\"");
            headerReq.append(", oauth_signature_method=\"base64\"");
            headerReq.append(", oauth_signature=\"")          .append(baseEncoder.encode(PropsUtil.get(OAUTH_CONSUMER_SECRET).getBytes()))
                    .append(baseEncoder.encode("&".getBytes()))            .append(baseEncoder.encode(symmetricEncrypter.decryptData(OAUTH_TOKEN_SECRET).getBytes())).append("\"");
            headerReq.append(", oauth_version=\"1.0\"");
            httpGet.addHeader("Authorization", headerReq.toString());
            CloseableHttpResponse response = httpclient.execute(httpGet);
            try {
                System.out.println("Responsee::"+ response.getStatusLine());
}

而且，我得到的回应是：

<?xml version="1.0" encoding="utf-8"?>
<PlatformResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://platform.intuit.com/api/v1">
  <ErrorMessage>This API requires Authorization.</ErrorMessage>
  <ErrorCode>22</ErrorCode>

在创建Oauth 1.0标准的请求时，您能否告诉我我缺少的内容或者，任何人都可以提供该标准的Oauth 1.0请求示例的示例代码。

非常感谢你。

当所有密钥都在手中时，这是java中的工作HTTP GET请求代码。希望它能完成你的工作。

import java.io.IOException;

import oauth.signpost.OAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;

import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.client.methods.*;  //HttpHead, HttpPut, HttpGet, etc...
import org.apache.http.util.EntityUtils;

public class HttpGetRequest {

public static void demo() throws IOException {           
    String consumer_key = "bcd";
    String consumer_secret = "efg";
    String access_token = "rst";
    String access_secret= "xzy";

    OAuthConsumer consumer = new CommonsHttpOAuthConsumer(consumer_key,
consumer_secret);
    consumer.setTokenWithSecret(access_token, access_secret);


    String uri = "your url here";
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(uri);
    try {
        consumer.sign(httpget);
    } catch (OAuthMessageSignerException ex) {
        Logger.getLogger(HttpRequest.class.getName()).log(Level.SEVERE,       null, ex);
    } catch (OAuthExpectationFailedException ex) {

    }
    HttpResponse response = httpclient.execute(httpget);
    System.out.println(response.getStatusLine().toString());
    HttpEntity entity = response.getEntity();
    System.out.println();
    System.out.println(EntityUtils.toString(entity));       
}
public static void main(String[] args) {
    try {

    catch(IOException ioe) {

这是我为构建OAuth v1 Authorization标头而创建的构建器。你可能会发现它很有用。

https://gist.github.com/robotdan/33f5834399b6b30fea2ae59e87823e1d

调用Twitter的示例用法：

String authorizationHeader = new OAuth1AuthorizationHeaderBuilder()
         .withMethod("POST")
         .withURL("https://api.twitter.com/oauth/access_token")
         .withConsumerSecret("twitterConsumerSecret")
         .withTokenSecret("your_oauth_token_secret")
         .withParameter("oauth_consumer_key", "your_consumer_key")
         .withParameter("oauth_token", "your_oauth_token")
         .build()
