个人中心模块-拍照剪裁上传

现在多数的网络应用都有个人中心的模块，里面少不了用户上传图像功能，正好最近项目里用到了这个就从网上找了一个集成进来，写得挺好的代码给大家推广一下。
废话不多说了，代码已经上传到网盘，有需要的朋友可以去下载来看看，这里处理一下上传的问题。

使用AsyncTask异步上传

private class RegHeadAsyncTask extends AsyncTask<String, Void, String> {

    protected void onPreExecute() {
    }

    protected BaseResponse doInBackground(String... params) {
        List<NameValuePair> postParams = new ArrayList<NameValuePair>();
        postParams.add(new BasicNameValuePair("uid", uid);
        postParams.add(new BasicNameValuePair("image", image));

        String response = null;
        try {
            String result = HttpClientUtil.uploadImg(HttpConfig.url_getHead(), postParams);
            if (TextUtils.isEmpty(result))
                return null;
            Gson gson = new Gson();
            // 解析上传图像操作，服务器返回的信息
            ...
        } catch (Exception e) {
            e.printStackTrace();
        }
        return response;
    }

    protected void onPostExecute(String result) {
        if (null != result) {
            // 服务器返回的信息
            ...
            if (flag) { // 上传成功
                ImageLoader.getInstance().displayImage(imageUrl, imageView); // 上传成功更新ui
            }
        }
    }
}

使用HTTP的POST方式提交（HttpClientUtil类）

public static String uploadImg(String url, List<NameValuePair> nameValuePairs) {
    BasicHttpParams httpParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParams, 10 * 1000);
    HttpConnectionParams.setSoTimeout(httpParams, 10 * 1000);
    HttpClient httpClient = new DefaultHttpClient(httpParams);
    HttpPost httpPost = new HttpPost(url);
    String result = "";

    try {
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

        for (int index = 0; index < nameValuePairs.size(); index++) {
            if (nameValuePairs.get(index).getName().equalsIgnoreCase("image")) {
                entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File(nameValuePairs.get(index).getValue()), "image/*"));
            } else {
                entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue()));
            }
        }

        httpPost.setEntity(entity);
        HttpResponse response = httpClient.execute(httpPost);

        if (response.getStatusLine().getStatusCode() == 200) {
            result = EntityUtils.toString(response.getEntity());
            return result;
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

图片上传PHP服务端（ThinkPhp）

// 图像上传
public function upimg() 
{ 
    $uptypes = array(
    'image/jpg',
    'image/jpeg',
    'image/png',
    'imagepeg',
    'image/gif',
    'image/bmp',
    'image/x-png'
    ); 
    $user_id=$_POST['uid'];
    $file = $_FILES["image"];
    $fname = $_FILES["image"]["name"];
    $fname_array = explode('.',$fname);
    $extend = $fname_array[count($fname_array)-1];
    $MAX_FILE_SIZE = 1024000;
    $dest_folder = "./Uploads/avatar/";;
    if($extend!=""){
    if(!in_array($file["type"],$uptypes)){
        jsonerror("只能上传图片文件");
    }
    if($file["size"]>$MAX_FILE_SIZE){
        jsonerror("头像大小不能超过1M");
    }
    $uploadfile = $dest_folder.$user_id.'.'.jpg;
    if(move_uploaded_file($_FILES["image"]["tmp_name"],$uploadfile)){
        $user_info=M('Users');
        $data['HeadImg']=$uploadfile;
        $result=$user_info->where("Uid=$user_id")->save($data);
        if($result === FALSE){
            jsonerror("头像修改失败");
        }else{
            jsonsuccess("头像修改成功");
        }
    }else{
        jsonerror("图片上传失败");
    }
} 


// 处理头像上传数据
public function upimgs() 
{ 
    // 判断是否上传会员卡
    if(!empty($_FILES['image']['name'])){
        $target_path  = "./Uploads/avatar/";//接收文件目录
        $filename     = $_FILES['image']['name'];  // 文件名称
        $exename      = $this->getExeName($filename); // 获取扩展名
        $filename     = $_POST['app_uid'].'.'.jpg;  // 将文件重命名
        $target_path = $target_path.$filename;
        
        if(move_uploaded_file($_FILES['image']['tmp_name'],$target_path)){
            $user_id=$_POST['app_uid'];
            $user_info=M('Users');
            $data['HeadImg']=$filename;
            $result=$user_info->where("Uid=$user_id")->save($data);
            if($result === FALSE){
                 jsonerror("头像修改失败");
            }else{
                jsonsuccess("头像修改成功！");
            }
        }else{
             jsonerror("上传图片有错误，请再试一次");
        }
    }
}

/**
* 获取文件扩展名
*/
public function getExeName($file)
{
    $arrName = explode('.',$file);
    return end($arrName);
}
