android上传base64的字符图片

一般来说，目前在手机端上传图片，方法挺多的，不过常用的就是一个文件流，另一个是二进制转base64的字符流，下面分享一下方法

网络上都是千篇一律的写法，对于上传过程中失败的问题也很少提及，上传失败的bug，主要的原因当然是编码字符的问题了，一般网上都没有介绍，记得要将base64的字符串 转化一下为utf-8，要不然会导致上传失败

Java代码

    
  
1.  
2. public static String httpPostBase64(byte[]  data, String url,String uid,String blog) {   
3.  String str=null;   
4.  try {   
5.  
6.   HttpPost httpRequest = new HttpPost(url);   
7.  
8.     
9.     
10.  
11.  
12.   List params = new LinkedList();   
13.   params.add(new BasicNameValuePair("uid", uid));   
14.   params.add(new BasicNameValuePair("blog", blog));   
15.   if(data!=null){   
16.    String data1 = Base64.encodeToString(data, 0, data.length,Base64.DEFAULT);   
17.    params.add(new BasicNameValuePair("img",URLEncoder.encode(data1,"UTF-8")));   
18.   }   
19.      
20.     
21.  
22.     
23.  
24.   httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));   
25.  
26.     
27.  
28.   HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);   
29.  
30.     
31.  
32.   if (httpResponse.getStatusLine().getStatusCode() != 200) {   
33.  
34.    Log.d("Code", httpResponse.getStatusLine().toString());   
35.  
36.    return str;   
37.  
38.   }else{   
39.     HttpEntity httpEntity=httpResponse.getEntity();   
40.     str = EntityUtils.toString(httpEntity,"UTF-8");   
41.    System.out.println("-------------------"+str);   
42.   }   
43.  
44.  } catch (Exception e) {   
45.  
46.   for (StackTraceElement s : e.getStackTrace())   
47.  
48.    Log.d("Exception", s.toString());   
49.  
50.   Log.d("Exception", e.getLocalizedMessage());   
51.  
52.   return str;   
53.  
54.  }   
55.  
56.  return str;   
57.  
58. }
