新浪微博java sdk如何获得一条评论的ＩＤ号

调用GetCategoryFeatures获取可用的Item Condition Definition，然后将某个Condition ID传递给AddItem或ReviseItem call

下面例程基于Java SDK调用GetCategoryFeatures。指定为US站点上编号63861的Category
[code="java"]package com.ebay.test;
import com.ebay.sdk.ApiAccount;
import com.ebay.sdk.ApiContext;
import com.ebay.sdk.ApiCredential;
import com.ebay.sdk.ApiLogging;
import com.ebay.sdk.CallRetry;
import com.ebay.sdk.call.GetCategoryFeaturesCall;
import com.ebay.soap.eBLBaseComponents.CategoryFeatureType;
import com.ebay.soap.eBLBaseComponents.ConditionEnabledCodeType;
import com.ebay.soap.eBLBaseComponents.ConditionType;
import com.ebay.soap.eBLBaseComponents.DetailLevelCodeType;
import com.ebay.soap.eBLBaseComponents.SiteCodeType;

public class AppGetCategoryFeatures {

public static ApiContext createApiContext() {

ApiContext apiContext = new ApiContext();
ApiLogging apiLogging = new ApiLogging();
apiContext.setApiLogging(apiLogging);
CallRetry cr = new CallRetry();
cr.setMaximumRetries(3);
cr.setDelayTime(1000); // Wait for one second between each retry-call.

String[] apiErrorCodes = new String[] { "502" };

// Set trigger exceptions for CallRetry.
cr.setTriggerApiErrorCodes(apiErrorCodes);

// Build a dummy SdkSoapException so that we can get its Class.
Class[] tcs = new Class[] { com.ebay.sdk.SdkSoapException.class };
cr.setTriggerExceptions(tcs);
apiContext.setCallRetry(cr);
apiContext.setTimeout(180000);

ApiCredential cred = new ApiCredential();
apiContext.setApiServerUrl("https://api.sandbox.ebay.com/wsapi");
// apiContext.setApiServerUrl("https://api.ebay.com/wsapi");

ApiAccount ac = cred.getApiAccount();
ac.setApplication(YOUR-APPID);
ac.setDeveloper(YOUR-DEVID);
ac.setCertificate(YOUR-CERTID);
cred.seteBayToken(YOUR-TOKEN);
apiContext.setApiCredential(cred);

return apiContext;

}

private static GetCategoryFeaturesCall getCatFeature(String categoryId, SiteCodeType site) {

GetCategoryFeaturesCall request = new GetCategoryFeaturesCall(
createApiContext());
request.setSite(site);
request.setDetailLevel(new DetailLevelCodeType[] { DetailLevelCodeType.RETURN_ALL });

request.setCategoryID(categoryId);
request.setOutputSelector(new String[] {
"Category.ConditionEnabled",
"Category.ConditionValues.Condition.ID",
"Category.ConditionValues.Condition.DisplayName" });

try {

request.getCategoryFeatures();

} catch (Exception e) {
e.printStackTrace();
}

return request;

}

public static void main(String[] args) {

GetCategoryFeaturesCall cf = getCatFeature("63861", SiteCodeType.US);

/*

• Since we call GetCategoryFeatures for a specified category, so we
• just get the first category element here */

CategoryFeatureType feature = cf.getReturnedCategory()[0];

/*

• If condition Enabled is disabled, then DO NOT pass conditionID in
• AddItem or ReviseItem for this category */

if (feature.getConditionEnabled().equals(ConditionEnabledCodeType.ENABLED)) {

for (ConditionType con : feature.getConditionValues().getCondition())

System.out.println(con.getID() + " - " + con.getDisplayName());
}

}

}
[/code]运行代码后，你会看到此Category的Condition ID Definitionf如下所示：

1000 - New with tags

1500 - New without tags

1750 - New with defects

3000 - Pre-owned

选择某个condition ID，如"New with tags"。在 AddItem或ReviseItem调用中设置condtionID为 "1000"
[code="java"]AddItemCall request = new AddItemCall(createApiContext());
ItemType item = new ItemType();
item.setConditionID(1000);

...

request.setItem(item);
request.addItem();

可以根据一条微博取得他下面的所有评论，然后你自己过滤取得想要的那条评论就可以了
[url]http://open.weibo.com/wiki/2/comments/show[/url]

JAVA SDK 提供的weibo4j代码 有获取指定微博下的所有评论
[code="java"]http://code.google.com/p/weibo4j/[/code]

[code="java"]package weibo4j.examples.comment;

import weibo4j.Comments;
import weibo4j.Weibo;
import weibo4j.examples.oauth2.Log;
import weibo4j.model.Comment;
import weibo4j.model.CommentWapper;
import weibo4j.model.WeiboException;

public class GetCommentById {

public static void main(String[] args) {
    String access_token = args[0];
    Weibo weibo = new Weibo();
    weibo.setToken(access_token);
    String id = args[1];
    Comments cm =new Comments();
    try {
        CommentWapper comment = cm.getCommentById(id);
        for(Comment c : comment.getComments()){
            Log.logInfo(c.toString());
        }
        System.out.println(comment.getTotalNumber());
        System.out.println(comment.getNextCursor());
        System.out.println(comment.getNextCursor());
        System.out.println(comment.getHasvisible());
    } catch (WeiboException e) {
        e.printStackTrace();
    }
}
