拉力賽的Java API回溯期

Question

這裏是我的代碼：

import com.google.gson.JsonElement; 
import com.rallydev.lookback.LookbackApi; 
import com.rallydev.lookback.LookbackQuery; 
import com.rallydev.lookback.LookbackResult; 
import java.math.BigInteger; 
import com.rallydev.rest.RallyRestApi; 
import com.rallydev.rest.request.QueryRequest; 
import com.rallydev.rest.response.QueryResponse; 
import com.rallydev.rest.util.Fetch; 
import com.rallydev.rest.util.QueryFilter; 
import java.io.*; 
import java.net.URI; 

import javax.management.Query; 
import com.google.gson.JsonObject; 

public class dIterationPsiAutomation { 
public String rallyURI; 
public String appName; 
public String username; 
public String password; 
public RallyRestApi restApi; 
public LookbackApi lookback; 
public dIterationPsiAutomation(String rallyURL,String username,String password, String applicationName) { 
    // TODO Auto-generated constructor stub 
    this.rallyURI = rallyURL; 
    this.appName = applicationName; 
    this.username = username; 
    this.password = password; 


    this.connect(this.rallyURI, this.appName, this.username, this.password); 
} 
public void connect(String uri,String app,String username,String password){ 
    try //Unhandled URI Exception occurs here 
    { 

     this.restApi = new RallyRestApi(new URI(uri),username,password); 
     this.restApi.setApplicationName("v2.0"); 
     this.restApi.setApplicationName(app); 
     this.lookback = new LookbackApi(); 
     this.lookback.setCredentials(username, password); 
     this.lookback.setWorkspace("Workspace 1"); 

    } 
    catch(Exception e){ 
     System.out.println("Exception occured "+e); 
    } 
} 
public void getFeatureInfo(String featureName) throws IOException { 
    QueryRequest feature = new QueryRequest("portfolioitem/feature"); 
    feature.setFetch(new Fetch("FormattedID","ObjectID","Name")); 
    feature.setQueryFilter(new QueryFilter("Name","=",featureName)); 

    QueryResponse queryResponse = this.restApi.query(feature); 


} 
public void get_formattedID(JsonElement ObjectID){ 

} 
public void get_prefixed_stories(String prefix){ 
    try{ 
     QueryRequest stories = new QueryRequest("hierarchicalrequirement"); 
     stories.setFetch(new Fetch("Children","Name","Iteration","FormattedID","ObjectID")); 
     stories.setQueryFilter(new QueryFilter("Name","contains",prefix)); 


     QueryResponse response = this.restApi.query(stories); 
     if(response.wasSuccessful()){ 
      System.out.println(String.format("Total result count %d", response.getTotalResultCount())); 
      for(JsonElement result: response.getResults()){ 
       JsonObject story = result.getAsJsonObject();  
       System.out.println(String.format("%s - %s: ObjectID: %s", story.get("FormattedID").getAsString(), story.get("Name").getAsString(), story.get("ObjectID").getAsBigInteger())); 
       get_all_leaf_stories(story.get("ObjectID").getAsBigInteger()); 
      } 
     } 
    } 
    catch(Exception e){ 
     System.out.println("Caught an exception in get_prefixed_stories method"); 
     System.out.println("More details "+e); 
    } 
} 
public void get_all_leaf_stories(BigInteger oID){ 
    try{ 
     LookbackQuery query = this.lookback.newSnapshotQuery(); 
     query.addFindClause("_TypeHierarchy", "HierarchicalRequirement"); 
     query.addFindClause("_ItemHierarchy", oID); 
     query.addFindClause("Children", null); 
     query.addFindClause("__At", "current"); 

     query.requireFields("Iteration","ObjectID","Name"); 
     query.sortBy("Iteration", -1); 

     LookbackResult resultSet = query.execute(); 
     if(resultSet.hasWarnings()){ 
      System.out.println("Errors in lookback "+resultSet.Errors); 
     } 
     int resultCount = resultSet.Results.size(); 

     System.out.println("Lookback resultset is "+resultCount); 
    } 
    catch(Exception e){ 
     System.out.println("Lookback Exception "+e); 
    } 
} 
} 

我得到一個IllegalArgumentException，當我嘗試使用LBAPI。任何人都可以幫助我嗎？

Answer 1

我認爲在README for Rally-Lookback-Toolkit的例子是誤導/錯誤的方式，它通過名稱指定工作區：

lookbackApi.setWorkspace("myworkspace");

當我這樣做，我看到LBAPI以下錯誤：

Lookback Exception com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1

在REST URL中需要什麼實際上是Workspace ObjectID而不是名稱。因此，如果你在代碼中設置工作區對象ID：

this.lookback.setWorkspace("12345678910");

我想查詢應爲你工作。
