Log format output JSON content

One of the things that I used to do is to copy the JSON returned to the Format tool and look at the contents, and the JSON format method is not very convenient to format the log directly.

A simple Log class written earlier (Log.java)

Importandroid.text.TextUtils;/*** Log information * *@authorHarlan Song * @createDate 2013-2-8*/ Public classLog {/*** Log Switch*/    Private Static BooleanIsdebug =true; Private Static FinalString AUTHOR = "HARLAN--";  Public Static voidDebugBooleanstatus) {Isdebug=status; }     Public Static voidd (string tag, string message) {if(isdebug) {android.util.log.d (Tag,author+message); }    }     Public Static voidI (string tag, string message) {if(isdebug) {ANDROID.UTIL.LOG.I (tag, AUTHOR+message); }    }    /*** JSON formatted OUTPUT *@paramTag *@paramMessage content *@paramisoutputoriginalcontent whether to enter the original content*/     Public Static voidIjsonformat (string tag, string message,Booleanisoutputoriginalcontent) {        if(Isdebug &&!)textutils.isempty (message)) {            if(isoutputoriginalcontent) android.util.log.i (tag, AUTHOR+message); ANDROID.UTIL.LOG.I (tag, AUTHOR+ "\ n" +Jsonutils.format (stringutils.convertunicode (message))); }    }     Public Static voidW (string tag, string message) {if(isdebug) {ANDROID.UTIL.LOG.W (Tag,author+message); }    }     Public Static voide (String tag, string message) {if(isdebug) {ANDROID.UTIL.LOG.E (Tag,author+message); }    }}

Call Ijsonformat, first the content Unicode conversion and then format the JSON, or if the display is Unicode after the content of Chinese can not see it is not convenient.


Unicode decoding method, a lot of online.

  Public Staticstring Convertunicode (string ori) {CharAchar; intLen =ori.length (); StringBuffer Outbuffer=NewStringBuffer (len);  for(intx = 0; X <Len;) {Achar= Ori.charat (x + +); if(Achar = = ' \ \ ') {Achar= Ori.charat (x + +); if(Achar = = ' U ') {                    //Read the XXXX                    intValue = 0;  for(inti = 0; I < 4; i++) {Achar= Ori.charat (x + +); Switch(Achar) { Case' 0 ':                             Case' 1 ':                             Case' 2 ':                             Case' 3 ':                             Case' 4 ':                             Case' 5 ':                             Case' 6 ':                             Case' 7 ':                             Case' 8 ':                             Case' 9 ': Value= (value << 4) + Achar-' 0 ';  Break;  CaseA:                             Case' B ':                             CaseC:                             Case' d ':                             CaseE:                             Case' F ': Value= (value << 4) + + Achar-' a ';  Break;  CaseA:                             CaseB:                             CaseC:                             CaseD:                             CaseE:                             CaseF: Value= (value << 4) + + Achar-' A ';  Break; default:                                Throw NewIllegalArgumentException ("Malformed \\UXXXX encoding."); }} outbuffer.append ((Char) value); } Else {                    if(Achar = = ' t ') Achar= ' \ t '; Else if(Achar = = ' R ') Achar= ' \ r '; Else if(Achar = = ' n ') Achar= ' \ n '; Else if(Achar = = ' F ') Achar= ' \f ';                Outbuffer.append (Achar); }            } Elseoutbuffer.append (Achar); }        returnoutbuffer.tostring (); }

The JSON format method is also found online.

  Public Staticstring Format (string jsonstr) {intLevel = 0; StringBuffer Jsonformatstr=NewStringBuffer ();  for(intI=0;i<jsonstr.length (); i++){            Charc =Jsonstr.charat (i); if(level>0&& ' \ n ' ==jsonformatstr.charat (Jsonformatstr.length ()-1) {jsonformatstr.append (level)) {GETLEVELSTR); }            Switch(c) { Case‘{‘:                 Case‘[‘: Jsonformatstr.append (c+ "\ n"); level++;  Break;  Case‘,‘: Jsonformatstr.append (c+ "\ n");  Break;  Case‘}‘:                 Case‘]‘: Jsonformatstr.append ("\ n"); level--;                    Jsonformatstr.append (level) (GETLEVELSTR);                    Jsonformatstr.append (c);  Break; default: Jsonformatstr.append (c);  Break; }        }        returnjsonformatstr.tostring (); }    Private StaticString Getlevelstr (intLevel ) {StringBuffer Levelstr=NewStringBuffer ();  for(intLeveli = 0;leveli<level; leveli++) {levelstr.append ("\ T"); }        returnlevelstr.tostring (); }
