Android 正在获取\n编码base64，因此无法将其转换为JSONObject

我想对3张照片进行编码，没有问题，当我想将该字符串发送到PHP并使用JSON将该字符串保存在MySQL中时，我遇到了问题。日志如下（仅在第一张照片中出现）：

06-19 14:56:18.141 29570-29586/com.example.indraaaeff.e_fine2 e/JSON解析器﹕ 分析数据org.json.JSONException:Value时出错

---

然后我尝试在debugger中打印出来，我看到字符串确实包含

\n

，这意味着

添加一些代码以便我们可以提供帮助。请添加log cat exception我不确定为什么要对base64中的内容进行json编码。。。但是，您可以只对字符串进行json编码吗？在编码它之前，它不应该被包装在数组或散列中吗？我在那里添加了log cat，ajitso先生，我不应该将字符串包装在数组或散列中？你能用代码sir@Michael sqlbot解释一下吗？
