JsonObject 抛出 com.google.gson.stream.MalformedJsonException

Question

我正在尝试从 Newsapi.org 获取文章并在 Java 中将它们解析为字符串，以便使用我的 Java Telegram-Abilities Bot 发送这些文章。我尝试使用不同的方法来解析 java.

中的 JSON

import org.json.*;
import org.apache.http.*;
import com.google.gson.JsonArray;
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

public String GetNews() {
  StringBuilder random = new StringBuilder();
  StringBuilder failed = new StringBuilder();
  String json = ("https://newsapi.org/v2/top-headlines?country=de&category=business&apiKey=myapikeyhere");
   try {
    JsonObject jsonObject = new
    JsonParser().parse(json).getAsJsonObject(); // PROBLEM HERE!!!! Throws 
    com.google.gson.stream.MalformedJsonException
    String article =
     jsonObject.getAsJsonObject("id").get("name").getAsString();
    System.out.println(article);


    //String status = 
    obj.getJSONObject("source").getString("name");

    JsonArray arr = jsonObject.getAsJsonArray("articles");
    for (int i = 0; i < 3; i++) {
     String post_id =
      arr.get(i).getAsJsonObject().get("id").getAsString();
     System.out.println(post_id);
     random.append(post_id);
    }
    return random.toString();
   } catch (JsonSyntaxException ex) {
    String post_id = ("Critical Error");
    failed.append(post_id);
   }
   return failed.toString();
}

com.google.gson.stream.MalformedJsonException

Answer 1

您是否错过了 API GET 方法，它实际上是在拉取您的响应？

String json = ("newsapi.org/v2/top-headlines? country = de & category = business & apiKey = myapikeyhere ");

目前只是一个字符串，因为从 API 返回的是一个 well-formed JSON 对象
