Question

我在使用Google地图引擎数据源保存数据时遇到问题。错误：缓冲区长度大于1：{＆＃34;错误＆＃34;：{＆＃34;错误＆＃34;：[{＆＃34;域＆＃34;：＆＃34;全球＆＃34;，＆＃34;原因＆＃34;：＆＃34;无效＆＃34;，＆＃34;消息＆＃34;：＆＃34;此值无效。＆＃34; }，＆＃34;代码＆＃34;：400，＆＃34;消息＆＃34;：＆＃34;此值无效。＆＃34; }}

其中＆＃34;缓冲区长度大于1＆＃34;是一个自定义消息。

功能是有效的Json。

            urlConnection.setDoOutput(true);

            }

            OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());


            JSONArray latLngAry = new JSONArray();
            latLngAry.put(Float.parseFloat(lng));

    }

Answer 1

您打算在此处返回true吗？对于buffer.length() < 1，任何大于空缓冲区的值都将导致它返回false。因此，如果预计会调用buffer.append(line)，您将始终返回false。

我建议更改buffer.length() < 1条件。
