InputStream 到 JSONElement 异常

Question

我正在尝试使用以下代码将 InputStream 转换为 JSON 元素

public jsonElement  parsejsonContentFromStream (Inputstream in){
Charset inputCharset = StandardCharsets.UTF-8;
InputStreamReader isr = new InputStreamReader(in, inputCharset);
BufferedReader bufferedReader = new  BufferedReader (isr);
JsonParser parser = new JsonParser();
return parser.parse(bufferedReader);
}

例外

Not a JSON object : “\u001f?\b\u000\u000\u0004\u0003uT”

然后我尝试了下面的代码

public JsonElement parseJsonContentFromStream(InputStream in) {
InputStreamReader ir = new InputStreamReader(in);
logger.info("Encode ="+ ir.getEncoding());
InputStreamReader isr = new InputStream Reader(in, StandardCharsets.UTF_8);
JsonReader jr = new JsonReader(isr);
JsonElement je=JsonParser.parseReader(jr).getAsJonObject();
return je;
}

仍然看到相同的错误消息。

Info:Encode = Cp1252
Java.lang.illegalStateException:Not a JSON object : “\u001f?\b\u000\u000\u0004\u0003uT”

请忽略任何语法错误。

Answer 1

InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, "UTF-8"));
StringBuilder responseStrBuilder = new StringBuilder();

String inputStr;
while ((inputStr = streamReader.readLine()) != null)
    responseStrBuilder.append(inputStr);

JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

试试这个。
