我正在尝试从我的Python Web服务器解析其余的响应。我成功获取了JSON内容的字符串。为了简化问题,我现在仅尝试解析下面显示的测试字符串。
我的python测试用例很好地解析了字符串,但这是针对Java插件的,因此我尝试将其翻译为Java。
我遵循了几个看似相同示例的副本。
String inputJSONs = "{\"connections\":[{\"num\":\"1\"},{\"num\":\"2\"}]}";
System.out.println("testing");
JSONObject jsono = new JSONObject(inputJSONs);
System.out.println("parsed json");
JSONArray arr = jsono.getJSONArray("connections");
System.out.println("have arr");
System.out.println(arr);
错误o.a.g.rest.RESTExceptionMapper-意外的内部错误:org / json / JSONObject
我认为插件框架(apache guacamole)可能隐藏了一些更详细的错误,但我不确定。
package org.apache.guacamole.auth;
import java.util.HashMap;
import java.util.Map;
import java.lang.StringBuilder;
import org.json.JSONObject;
import org.json.JSONArray;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.apache.guacamole.GuacamoleException;

import org.apache.guacamole.environment.LocalEnvironment;
import org.apache.guacamole.net.auth.simple.SimpleAuthenticationProvider;
import org.apache.guacamole.net.auth.Credentials;
import org.apache.guacamole.protocol.GuacamoleConfiguration;
public class RestAuthenticationProvider extends SimpleAuthenticationProvider {
private final Environment environment;
private Logger logger = LoggerFactory.getLogger(RestAuthenticationProvider.class.getClass());
public RestAuthenticationProvider() throws GuacamoleException{
environment = new LocalEnvironment();
}
@Override
public String getIdentifier() {
logger.info("====Get Identifier====");
return "Rest API";
}
@Override
public Map<String, GuacamoleConfiguration>
getAuthorizedConfigurations(Credentials credentials)
throws GuacamoleException {
if (credentials.getUsername() == null ){
return null;
}
String inputJSONs = "{\"connections\":[{\"num\":\"1\"},{\"num\":\"2\"}]}";
System.out.println("testing 2");
System.out.println(inputJSONs);
JSONObject jsono = new JSONObject(inputJSONs);
System.out.println("parsed json");
JSONArray arr = jsono.getJSONArray("connections");
System.out.println("have arr");
System.out.println(arr);
return null;
}
}
登录服务器后立即输出以下
testing 2
{"connections":[{"num":"1"},{"num":"2"}]}
12:00:00.129 [http-nio-8080-exec-8] ERROR o.a.g.rest.RESTExceptionMapper - Unexpected internal error: org/json/JSONObject
答案 0 :(得分:0)
在鳄梨酱特定论坛的帮助下,我可以缩小范围。最终的解决方法是让Maven使用内置的依赖项构建一个胖子。
我在pom.xml中添加了以下内容
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<!-- MainClass in mainfest make a executable jar -->
<archive>
<manifest>
<mainClass>com.mkyong.core.utils.App</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
