JSon 数据中的String 传递数据时，需要处理好特殊字符.

JSon数据中有特殊字符:

1：引号 ，如果是使用单引号，来括值的话，那String 中  '  单引号为特殊字符

2：正斜杠，反斜杠，换行符号等。另外，必须用 (") 而非 (') 表示字符串：

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  /\*\*
2.       \* JSON字符串特殊字符处理，比如：“\\A1;1300”
3.       \* @param s
4.       \* @return String
5.       \*/ 
6.      **public** String string2Json(String s) \{       
7.          StringBuffer sb = **new** StringBuffer();       
8.          **for** (**int** i=0; i<s.length(); i++) \{ 
9.              **char** c = s.charAt(i);   
10.              **switch** (c)\{ 
11.              **case** '\\"':       
12.                  sb.append("\\\\\\"");       
13.                  **break**;       
14.              **case** '\\\\':       
15.                  sb.append("\\\\\\\\");       
16.                  **break**;       
17.              **case** '/':       
18.                  sb.append("\\\\/");       
19.                  **break**;       
20.              **case** '\\b':       
21.                  sb.append("\\\\b");       
22.                  **break**;       
23.              **case** '\\f':       
24.                  sb.append("\\\\f");       
25.                  **break**;       
26.              **case** '\\n':       
27.                  sb.append("\\\\n");       
28.                  **break**;       
29.              **case** '\\r':       
30.                  sb.append("\\\\r");       
31.                  **break**;       
32.              **case** '\\t':       
33.                  sb.append("\\\\t");       
34.                  **break**;       
35.              **default**:       
36.                  sb.append(c);    
37.              \} 
38.          \}     
39.         **return** sb.toString();    
40.         \}
