特殊字符问题
我对 HttpPost 的 json 响应有问题，响应包含类似 & 的字符。哎呀；这会导致在创建 jsonobject 或 jsonarray 时生成异常。
有人知道如何解码吗？我必须在请求中添加标头吗？
多谢。
编辑：
我已经使用了 log cat，这是例外

& hellip ; 通过堆栈溢出直接转换
i have a problem with a json response of an HttpPost , the resposnse contains character like & hellip; and this cause to generate an exception while creating the jsonobject or a jsonarray.
Anyone knows how decode it? i have to add an header in the request?

也许这不是编码问题：从我看到的错误日志中，您尝试将
String转换为JSONArray。我不是 JSON 领域的专家，但JSONArray是一个集合，我希望您尝试将字符串（包括椭圆字符）添加到（现有的）JSON 数组，而不是尝试从字符串创建数组。JSON 期望所有字符串均为 UTF-8 格式，因此它确实应该能够处理椭圆字符。
Maybe it's not an encoding problem: from the error log I see, that you try to convert a
Stringto aJSONArray. I'm not an expert in the JSON domain, but aJSONArrayis a collection and I'd expect that you try to add the String (including the ellipse char) to the (existing) JSON array rather then trying to make an array from the String.JSON expects all Strings to be in UTF-8 format, so it really should be able to handle the ellipse char.
