Android 上传头像(文件)到服务器

深碍√TFBOYSˉ_ 2022-07-18 05:19 314阅读 0赞

现在很多app都用到了头像的功能，我的项目中也用到了。  
头像上传分几步：  
1.获取头像  
2.剪裁头像  
3.文件上传  
4.服务器的接受保存  
首先第一步，无非就是两种方式  
1，拍照  
2，相册选择  
之前的博客中有现到，不重复，链接：

第二步，裁剪头像  
这一步我用的时鸿洋大神的东西，是个自定的控件，不过我对其中代码进行了一点点的修改，使之更适合自己的项目，里面原理就是监听onTouchEvent来对缩放，双击事件进行相应的处理，裁剪就是根据大小，创建一个新的bitmap，当然说起来挺简单，如果没有别人的代码可以借鉴参考，估计有的搞了，在此谢谢鸿洋大神，下面是鸿洋大神的博客链接：

裁剪图片好像还可以调用Android自带的裁剪功能，不过我没用过，  
第三步，上传图片，  
上传图片不过也就是上传文件，可以将文件转化为byte数组然后进行base64转码后进行上传，在服务器接收到后，将string解码成byte数组，然后在转化为文件。  
当然上传的方法有很多，肯定不止这一种 ，因为项目的Android和web接口都是我写的所已我就这样写啦…谁让自己的web技术有限呢，原来写Android的时候一直说调用接口接口，原来自己写了才知道，其实就是一个配置好servlet的java文件.⊙﹏⊙||  
写接口和写Android差不过嘛，都是用Java写的，本家嘛  
对了文件上传的时候如果从本地读取，会需要读取sd卡的权限，我在6.0的模拟器上测试的时候，一直有问题，找了半天才发现是因为，没有申请权限，，，设立的权限不仅仅时AndroidManifest里面的权限声明，在6.0的系统中需要用代码弹出对话框向用户申请..  
贴下请求代码

/**
         * 请求权限
         */
        public void getUserPar() {
    //        Log.d("测试--授权信息", ContextCompat.checkSelfPermission(this,
    //                Manifest.permission.WRITE_EXTERNAL_STORAGE) + "");
    //        Log.d("测试--已授权", PackageManager.PERMISSION_GRANTED + "");
    //        Log.d("测试--未授权", PackageManager.PERMISSION_DENIED + "");
            if (ContextCompat.checkSelfPermission(this,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this,
                    Manifest.permission.READ_EXTERNAL_STORAGE)
                    == PackageManager.PERMISSION_GRANTED) {
            } else {
                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE},
                        1);
            }
        }
    
        @Override
        public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
            switch (requestCode) {
                case 1: {
                    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                        L.d("同意");
                    } else {
                        L.d("拒绝");
                    }
                    return;
                }
            }
        }

还有文件和数组相互转化的代码

/**
         * 将file文件转化为byte数组
         *
         * @param filePath
         * @return
         */
        public static byte[] getBytes(String filePath) {
            byte[] buffer = null;
            try {
                File file = new File(filePath);
                FileInputStream fis = new FileInputStream(file);
                ByteArrayOutputStream bos = new ByteArrayOutputStream(1000);
                byte[] b = new byte[1000];
                int n;
                while ((n = fis.read(b)) != -1) {
                    bos.write(b, 0, n);
                }
                fis.close();
                bos.close();
                buffer = bos.toByteArray();
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return buffer;
        }
    
        /**
         * 将byte数组转化为file文件
         *
         * @param bfile
         * @param filePath
         * @param fileName
         */
        public static void getFile(byte[] bfile, String filePath, String fileName) {
            BufferedOutputStream bos = null;
            FileOutputStream fos = null;
            File file = null;
            try {
                File dir = new File(filePath);
                if (!dir.exists() && dir.isDirectory()) {
       // 判断文件目录是否存在
                    dir.mkdirs();
                }
                file = new File(filePath + "\\" + fileName);
                fos = new FileOutputStream(file);
                bos = new BufferedOutputStream(fos);
                bos.write(bfile);
                bos.flush();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (bos != null) {
                    try {
                        bos.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                }
                if (fos != null) {
                    try {
                        fos.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                }
            }
        }

还有base64转码的：

        }
    
    
    }

关于上传文件到服务器的.两种思路或者是方法.  
1.将文件转成base64编码放在字段里面,像正常的http交互一样去访问服务器上传  
2.将文件写入流中上传
