org.apache.http请求较多数据出错

Question

在学Android，我通过org.apache.http 和 SAX 请求服务器并解析一个返回的xml。
比如返回以下一个XML，我通过一个url参数count控制返回review的数量<?xml version="1.0" encoding="UTF-8"?>
<reviews>
<review>
<timestamp_id>动态记录Id</timestamp_id>
<created_at>创建时间</created_at>
<id>评论ID</id>
<content>内容</content>
<img>用户拍摄的图片</img>
<type>评论类型（0为详细评论，1为简评，2为签到）</type>
<user>
<id>用户ID</id>
<name>用户名</name>
<face_pic>头像地址</face_pic>
</user>
<product>
<id>产品ID</id>
<name>产品名称</name>
<img>产品图片</img>
</product>
</review>
                        <review>
<timestamp_id>动态记录Id</timestamp_id>
<created_at>创建时间</created_at>
<id>评论ID</id>
<content>内容</content>
<img>用户拍摄的图片</img>
<type>评论类型（0为详细评论，1为简评，2为签到）</type>
<user>
<id>用户ID</id>
<name>用户名</name>
<face_pic>头像地址</face_pic>
</user>
<product>
<id>产品ID</id>
<name>产品名称</name>
<img>产品图片</img>
</product>
</review>
....
</reviews>但是当count<= 9时能够正常返回，大于9时会报错误，如下

java.net.SocketException: socket closed不知道是何原因，求解

Answer 1

把你的连接服务器，读取返回数据的代码贴出来
估计是socket超时，或者缓冲区的问题

    HttpPost post = new HttpPost(url);
    post.setParams(httpParameters);
    if(parmList != null){
    post.setEntity(new UrlEncodedFormEntity(parmList, HTTP.UTF_8));

    HttpResponse response =  httpClient.execute(post);
    HttpEntity entity = response.getEntity();
    InputStream instream = null;
    if (entity != null) {
    instream = entity.getContent();
    }
   
    post.abort();
    return instream;
   }
}

Answer 3

java.net.SocketException: socket closed  
 这个遭关了哦

Answer 4

找到出错地方了，我居然在最后调用了HttpPost的abort()方法，导致退出整个请求，所以纠结一天的东西终于结束了
