  android解析json出错：JSONException: Value of type java.lang.String cannot be converted to JSONObject。

   

    很简单的一个json字符串： {"statu":"1","results":"true"},明显看着是没什么格式错误的，然后用各种json格式校验工具检测也都没什么问题，但程序里就一直报错。

   

   google之后发现是BOM报头问题。服务器端是php，返回的接送数据'{'前有bom报头，java读的时候把报头直接当作文件内容读，然后就会出错。

一般是服务器端代码格式的问题

一、

    BOM报头又叫UTF-8签名,其实UTF-8  的BOM对UFT-8没有作用,是为了支援UTF-16,UTF-32才加上的BOM,BOM签名的意思就是告诉编辑器当前文件采用何种编码,方便编辑器 识别,但是BOM虽然在编辑器中不显示,但是会产生输出,就像多了一个空行,一般的php代码如果用记事本等软件编辑保存过之后，在保存一个以UTF-8编码的文件时，会在文件开始的地方插入三个不可见的字符（0xEF 0xBB  0xBF，即BOM）。它是一串隐藏的字符，用于让记事本等编辑器识别这个文件是否以UTF-8编码。（还不清楚为什么会在返回数据时候也自动加上了BOM报头）。

 

java、android客户端等可以通过代码过滤掉bom，然后再解析。

/** * 去除bom报头 */public static String formatString(String s) {    if (s != null) {          s = s.replaceAll("\ufeff", "");    }    return s;}

这个bom问题真是困扰了很久。。。

 

服务器端过滤掉bom可以参考这篇文章：
