我正在使用this wrapper开发一个android reddit应用。我能够登录，除了它解析时遇到了一些问题。这是代码：
package com.example.reddit;
import im.goel.jreddit.submissions.Submission;
import im.goel.jreddit.submissions.Submissions;
import im.goel.jreddit.user.User;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView username;
private TextView password;
private User reddit;
private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username = (EditText) findViewById(R.id.username);
password = (EditText) findViewById(R.id.password);
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String usern = username.getText().toString();
String passw = password.getText().toString();
reddit = new User(usern, passw);
try {
reddit.connect();
for (Submission submission : Submissions.getSubmissions("cfb",
Submissions.Popularity.HOT, Submissions.Page.FRONTPAGE, reddit)) {
submission.upVote();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
LogCat在运行它并单击按钮时输出的消息是：

显然，它正在从/ r / cfb的首页提交提交，但它只能读取1024个字节。错误是Unexpected token END OF FILE at position 1024。任何人都知道这是什么或如何解决它？
答案 0 :(得分：0)
检索信息时缓冲区溢出。因此，我们不是获取并尝试存储reddit返回的所有数据，而是动态地解析它以获取所需信息并存储它。更高效并解决了缓冲区溢出错误。类似的东西：
JSONArray array = (JSONArray) ((JSONObject) object.get("data"))
.get("children");
JSONObject data;
for (int i = 0; i < array.size(); i++) {
data = (JSONObject) array.get(i);
}
