Json 中的控制字符导致 JsonParsingException

Question

我有这个java方法：

public class ReadIssues {

  // Reads from a Json object

  protected JsonArray readJson() throws IOException {

    JsonArray issueArray = null;

    ClassLoader cl = Thread.currentThread().getContextClassLoader();

    // Get input stream for reading the specified resource

    InputStream inputStream = cl.getResourceAsStream("GitHubIssue.json");

    // Create JsonReader to read JSON data from a stream

    Reader reader = new InputStreamReader(inputStream, "UTF-8");

    JsonReader jsonReader = Json.createReader(reader);

    try{      

      // Create an object model in memory

      issueArray = jsonReader.readArray();

      System.out.println("ReadIssues issueArray: " + issueArray);

    }

    finally {

      if (inputStream != null) {

        inputStream.close();        

      }

      if (jsonReader != null) {

        jsonReader.close();

      }

    }

    return issueArray;

  }

它抛出这个异常：

Exception in thread "main" javax.json.stream.JsonParsingException: Unexpected char 117 at (line no=1, column no=5, offset=4)

问题似乎是issueArray = jsonReader.readArray();。我认为body我的 JSON 中的值包含\n和等字符\r。

我遇到了一个帖子，建议做类似的事情，json = json.replaceAll("\r?\n", "");但那json是String. 在我使用 JsonReader 对象的情况下，我应该怎么做？
