【问题描述】：
我正在尝试使用 Java 使用 REST API。使用 Oauth1 进行身份验证。代码块如下-
import java.io.InputStream;
import java.io.StringWriter;
import java.net.URI;
import java.net.URISyntaxException;
import oauth.signpost.OAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.exception.OAuthCommunicationException;
import oauth.signpost.exception.OAuthExpectationFailedException;
import oauth.signpost.exception.OAuthMessageSignerException;
import oauth.signpost.signature.AuthorizationHeaderSigningStrategy;
import org.apache.commons.io.IOUtils;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpRequestBase;
import org.apache.http.impl.client.DefaultHttpClient;
import javax.swing.text.html.FormSubmitEvent;
public class Oauth1RestCallWithOutToken {
private OAuthConsumer oAuthConsumer;
public Oauth1RestCallWithOutToken() {
String consumerKey = "my_consumer_key";
String consumerSecret = "my_consumer_secret";
setupContext(consumerKey, consumerSecret);
}
public void setupContext(String consumerKey, String consumerSecret) {
this.oAuthConsumer = new CommonsHttpOAuthConsumer(consumerKey, consumerSecret);
//oAuthConsumer.setTokenWithSecret("", "");
oAuthConsumer.setSigningStrategy(new AuthorizationHeaderSigningStrategy());
}
public void authorize(HttpRequestBase httpRequest) {
try {
oAuthConsumer.sign(httpRequest);
} catch (OAuthMessageSignerException e) {
} catch (OAuthExpectationFailedException e) {
} catch (OAuthCommunicationException e) {
}
}
public void executeGetRequest(String customURIString){
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter("http.protocol.content-charset", "UTF-8");
HttpRequestBase httpRequest = null;
URI uri = null;
try {
uri = new URI(customURIString);
} catch (URISyntaxException e) {
e.printStackTrace();
}
String methodtype = "GET";
if (methodtype.equals(FormSubmitEvent.MethodType.GET.toString())) {
httpRequest = new HttpGet(uri);
}
httpRequest.addHeader("content-type", "application/json");
httpRequest.addHeader("Accept","application/json");
try {
authorize(httpRequest);
} catch (Exception e) {
e.printStackTrace();
}
HttpResponse httpResponse = null;
try {
HttpHost target = new HttpHost(uri.getHost(), -1, uri.getScheme());
httpResponse = client.execute(target, httpRequest);
System.out.println("Connection status : " + httpResponse.getStatusLine());
InputStream inputStraem = httpResponse.getEntity().getContent();
StringWriter writer = new StringWriter();
IOUtils.copy(inputStraem, writer, "UTF-8");
String output = writer.toString();
System.out.println(output);
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String args[]) {
String url="https:host/order-manager/orders";
//url="https:host/order-manager/orders?in(internalId,12345)";
Oauth1RestCallWithOutToken withoutDevkitClient = new Oauth1RestCallWithOutToken();
withoutDevkitClient.executeGetRequest(url);
}
}

如果使用诸如“https:host/order-manager/orders”之类的 URL，我将获得成功的响应。
但是，如果使用包含 RQL 参数的 URL，例如“https:host/order-manager/orders?in(internalId,12345)”，我会收到 500 个响应。在使用 Postman 或 Insomnia 时，这两个 URL 都可以正常工作。
你能帮我指出我的错误吗？或使用 java 使用 RQL 支持的 REST API 的任何建议。提前致谢。
