Android用戶端使用okhttp上傳檔案php伺服器

為了更好的在應對網路訪問，最近學習了一下okhttp，感覺挺方便使用的，首先要使用okhttp，需要在項目中匯入okhttp-x.x.x.jar okhttputils-x_x_x.jar okio-x.x.x.jar 這三個jar包，下面貼出Android端和伺服器端關鍵代碼：

private void uplodeImage(File mFile) {//mFile一個真實存在的圖片檔案if (!mFile.exists())        {            Toast.makeText(MainActivity.this, "檔案不存在，請修改檔案路徑", Toast.LENGTH_SHORT).show();            return;        }OkHttpUtils.post().url(UPLODE_URL)    .addFile("file", mFile.getName(), mFile)    .build()    .execute(new Callback() {@Overridepublic void onError(Call arg0, Exception arg1) {System.out.println("上傳檔案失敗");info.setText("REEOR:upload error!");}@Overridepublic void onResponse(String arg0) {//System.out.println(arg0);//上傳成功返迴文件在伺服器上的唯一路徑，將此路徑儲存到資料庫中info.setText(arg0);//這裡會返回一個包含上傳檔案在伺服器上的唯一路徑，上傳成功後將這個字串儲存到資料庫中去}@Overridepublic String parseNetworkResponse(Response arg0) throws Exception {// TODO Auto-generated method stubreturn arg0.body().string();}}) ;}

伺服器端的代碼：

fileName=$fileName;$this->maxSize=$maxSize;$this->allowMime=$allowMime;$this->allowExt=$allowExt;$this->uploadPath=$uploadPath;$this->imgFlag=$imgFlag;$this->fileInfo=$_FILES[$this->fileName];}/** * 檢測上傳檔案是否出錯 * @return boolean */protected function checkError(){if(!is_null($this->fileInfo)){if($this->fileInfo['error']>0){switch($this->fileInfo['error']){case 1:$this->error='超過了PHP設定檔中upload_max_filesize選項的值';break;case 2:$this->error='超過了表單中MAX_FILE_SIZE設定的值';break;case 3:$this->error='檔案部分被上傳';break;case 4:$this->error='沒有選擇上傳檔案';break;case 6:$this->error='沒有找到臨時目錄';break;case 7:$this->error='檔案不可寫';break;case 8:$this->error='由於PHP的擴充程式中斷檔案上傳';break;}return false;}else{return true;}}else{$this->error='檔案上傳出錯';return false;}}/** * 檢測上傳檔案的大小 * @return boolean */protected function checkSize(){if($this->fileInfo['size']>$this->maxSize){$this->error='上傳檔案過大';return false;}return true;}/** * 檢測副檔名 * @return boolean */protected function checkExt(){$this->ext=strtolower(pathinfo($this->fileInfo['name'],PATHINFO_EXTENSION));if(!in_array($this->ext,$this->allowExt)){$this->error='不允許的副檔名';return false;}return true;}/** * 檢測檔案的類型 * @return boolean */protected function checkMime(){if(!in_array($this->fileInfo['type'],$this->allowMime)){$this->error='不允許的檔案類型';return false;}return true;}/** * 檢測是否是真實圖片 * @return boolean */protected function checkTrueImg(){if($this->imgFlag){if(!@getimagesize($this->fileInfo['tmp_name'])){$this->error='不是真實圖片';return false;}return true;}}/** * 檢測是否通過HTTP POST方式上傳上來的 * @return boolean */protected function checkHTTPPost(){if(!is_uploaded_file($this->fileInfo['tmp_name'])){$this->error='檔案不是通過HTTP POST方式上傳上來的';return false;}return true;}/** *顯示錯誤  */protected function showError(){return (Array(    'rType'=>-30,    'rMessage'=>$this->error    ));}/** * 檢測目錄不存在則建立 */protected function checkUploadPath(){if(!file_exists($this->uploadPath)){mkdir($this->uploadPath,0777,true);}}/** * 產生唯一字串 * @return string */protected function getUniName(){return md5(uniqid(microtime(true),true));}/** * 上傳檔案 * @return string */public function uploadFile(){if($this->checkError()&&$this->checkSize()&&$this->checkExt()&&$this->checkMime()&&$this->checkTrueImg()&&$this->checkHTTPPost()){$this->checkUploadPath();$this->uniName=$this->getUniName();$this->destination=$this->uploadPath.'/'.$this->uniName.'.'.$this->ext;if(@move_uploaded_file($this->fileInfo['tmp_name'], $this->destination)){return  Array(    'rType' => 0,    'rMessage' => $this->destination    );}else{$this->error='檔案移動失敗';$this->showError();}}else{return $this->showError();}}}

uploadFile(),JSON_UNESCAPED_UNICODE);

以上就介紹了Android用戶端使用okhttp上傳檔案php伺服器，包括了方面的內容，希望對PHP教程有興趣的朋友有所協助。
