java后台上传图片方式采用读取照片并编码后上传

本次主要实现base64编码上传

/\*\*

*  七牛token
 *  
 *  @return  
    \*/  
    public JSONObject getQiNiuToKen() \{  
    String accessKey = “xxxxxxxxxxxxxxxxx”;  
    String secretKey = “xxxxxxxxxxxxxxxxxxx”;  
    String bucket = “xxxxxx”;  
    Auth auth = Auth.create(accessKey, secretKey);  
    String upToken = auth.uploadToken(bucket);  
    JSONObject json = new JSONObject();  
    json.put(“uptoken”, upToken);  
    return json;  
    \}

生成base64编码

public byte\[\] getWxacode(String scene,String path)\{  
Map<String,Object> param = new HashMap<String,Object>();  
param.put(“scene”, scene);  
param.put(“page”, path);  
param.put(“width”, width);  
param.put(“auto\_color”, false);  
Map<String,Object> line\_color = new HashMap<>();  
line\_color.put(“r”, 0);  
line\_color.put(“g”, 0);  
line\_color.put(“b”, 0);  
param.put(“line\_color”, line\_color);  
RestTemplate rest = new RestTemplate();

try {
         MultiValueMap<String, String> headers = new LinkedMultiValueMap<>();
         HttpEntity requestEntity = new HttpEntity(JSON.toJSONString(param), headers);
         ResponseEntity<byte[]> entity = rest.exchange(CODE_ULR+"?access_token="+accessToken, HttpMethod.POST, requestEntity, byte[].class, new Object[0]);
         byte[] result = entity.getBody();
         return  result;
      } catch (Exception e) {
          // logger.info(e.getMessage());
      }finally {
    
      }
      return null;

/\*\*

*  base64上传并返回uuid
 *  
 *  @param base64
 *  @return
 *  @throws IOException  
    \*/  
    public Object getBase64ToString(byte\[\] base64) \{  
    JSONObject json = getQiNiuToKen();  
    String uuid = UUID.randomUUID().toString().replaceAll("-", “”);  
    String upToken = json.getString(“uptoken”);  
    String file64 = com.qiniu.util.Base64.encodeToString(base64, 0);  
    String url = “[https://upload-z2.qiniup.com/putb64/][https_upload-z2.qiniup.com_putb64]” + base64.length + “/key/” + UrlSafeBase64.encodeToString(uuid);  
    //非华东空间需要根据注意事项 1 修改上传域名 [华南域名用upload-z2.qiniup.com][upload-z2.qiniup.com]
    
    RequestBody rb = RequestBody.create(null, file64);  
    Request request = new Request.Builder().  
    url(url).  
    addHeader(“Content-Type”, “application/octet-stream”)  
    .addHeader(“Authorization”, "UpToken " + upToken)  
    .post(rb).build();  
    //System.out.println(request.headers());  
    OkHttpClient client = new OkHttpClient();  
    okhttp3.Response response = null;  
    try \{  
    response = client.newCall(request).execute();  
    System.out.println(response);  
    \} catch (Exception e) \{  
    ResultMsg.Error(“错误信息” + e);  
    \} finally \{  
    if (response.code() == 200) \{  
    return uuid;  
    \} else \{  
    return ResultMsg.Error(“上传失败”);  
    \}  
    \}  
    \}
