1.先列出Android端使用的library:
dependencies { ... compile 'com.jakewharton:butterknife:7.0.1' compile 'com.squareup:otto:1.3.5' compile 'cn.finalteam:galleryfinal:1.4.8.4' compile 'com.squareup.retrofit:retrofit:1.9.0' compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0' compile 'com.squareup.okhttp:okhttp:2.0.0' compile 'com.github.bumptech.glide:glide:3.6.1' compile 'com.jcodecraeer:xrecyclerview:1.2.6' compile 'com.baoyz.actionsheet:library:1.1.5' compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5' compile 'io.reactivex:rxjava:1.0.6' compile 'io.reactivex:rxandroid:0.23.0' compile files('libs/fastjson-1.2.7.jar')}
Android端代码:
public interface ApiService {// 上传一个文件/图片 @Multipart @POST("/UploadFileDemo/android_upload_file/upload.php") Observable<Response> uploadFile(@Part("uploadfile") TypedFile file);// 上传多张图片 @POST("/UploadFileDemo/android_upload_file/uploads.php") Observable<Response> uploadFiles(@Body MultipartTypedOutput multipartTypedOutput);}
public class Client { public static String API_URL = Constant.API_URL; public static ExecutorService mExecutorService; private static ApiService instance; public static ApiService getServiceClient() { if (instance == null) { synchronized (Client.class) { if (instance == null) { OkHttpClient okHttpClient = new OkHttpClient(); okHttpClient.setCookieHandler(new MyCookieManager()); okHttpClient.setReadTimeout(100, TimeUnit.SECONDS); okHttpClient.setConnectTimeout(100, TimeUnit.SECONDS); RestAdapter.Builder restAdapter = new RestAdapter.Builder(); restAdapter.setRequestInterceptor(new ApiHeaders()); restAdapter.setEndpoint(API_URL); restAdapter.setClient(new OkClient(okHttpClient)); restAdapter.setLogLevel(RestAdapter.LogLevel.FULL); mExecutorService = Executors.newCachedThreadPool(); instance = restAdapter.build().create(ApiService.class); } } } return instance; } public static void stopAll() { List<Runnable> pendingAndOngoing = mExecutorService.shutdownNow(); } static class MyCookieManager extends CookieManager { @Override public void put(URI uri, Map<String, List<String>> stringListMap) throws IOException { super.put(uri, stringListMap); if (stringListMap != null && stringListMap.get("Set-Cookie") != null) for (String string : stringListMap.get("Set-Cookie")) { String cookieValue = string.substring(0, string.indexOf("\"; ") + 1); if (string.contains("A2=\"")) { //保存到应用 } if (string.contains("PB3_SESSION=\"")) { ////保存到应用 } } } } static class ApiHeaders implements RequestInterceptor { @Override public void intercept(RequestFacade request) { request.addHeader("User-Agent", "Mozilla/5.0 (Linux; U; Android 4.1.1; zh-cn; HTC One X - 4.1.1 - API 16 - 720x1280 Build/JRO03S) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30"); request.addHeader("Accept", "*/*"); request.addHeader("Accept-Language", "zh-cn,zh"); } }}
上传关键代码:
//使用MultipartTypedOutput类来上传多张图片 public void uploadFiles(List<String> paths) { MultipartTypedOutput multipartTypedOutput = new MultipartTypedOutput(); for (String imgPath : paths){ //注意“uploadfile[]”一定要带“[]”,表明上传的是数组,也就是多张图片,不能写“uploadfile” multipartTypedOutput.addPart("uploadfile[]", new TypedFile("", new File(imgPath))); } mApi.uploadFiles(multipartTypedOutput) .subscribeOn(Schedulers.computation()) .subscribe(response -> handleUploadFile(response), error -> handleFailure(error)); } private void handleUploadFile(Response response) { System.out.println(response.getUrl()); try { InputStream in = response.getBody().in(); String responseString = inputStream2String(in); Log.i("AAA", responseString); //解析json数据 //otto事件传递 mBus.post(responseString); } catch (IOException e) { e.printStackTrace(); }}//接收事件代码 @Subscribe //需要注解@Subscribe ,表明在这个函数接收数据public void uploadFileResponse(String response) { Message msg = JSON.parseObject(response, Message.class); List<String> imgUrls = msg.getImgUrls(); if (msg.getCode() == 1) { if (choosePhotoListAdapter == null) { choosePhotoListAdapter = new ChoosePhotoListAdapter(this, null, imgUrls); lvPhotoShow.setAdapter(choosePhotoListAdapter); } choosePhotoListAdapter.notifyDataSetChanged(); }}
Php端代码:
//初学php,写的比较简单,不太健壮,像图片是否已经上传过,都没有判断,大家自己补充啊^_^<?php/** * Created by PhpStorm. * User: zhangyipeng * Date: 16/2/18 * Time: 下午3:48 */$base_path = "./upload_file/"; //接收文件目录$imgs = array(); //定义一个数组存放上传图片的路径$isSave = false;if (!file_exists($base_path)) { mkdir($base_path);}foreach ($_FILES["uploadfile"]["error"] as $key => $error) { if ($error == UPLOAD_ERR_OK) { $tmp_name = $_FILES["uploadfile"]["tmp_name"][$key]; $name = $_FILES["uploadfile"]["name"][$key]; $uploadfile = $base_path . $name; $isSave = move_uploaded_file($tmp_name, $uploadfile); if ($isSave){ $imgs[]=$uploadfile; } }}if ($isSave) { $array = array("code" => "1", "message" =>"上传图片成功" , "imgUrls" => $imgs); echo json_encode($array);} else { $array = array("code" => "0", "message" => "上传图片失败," . $_FILES ['uploadfile'] ['error'] , "imgUrls" => $imgs); echo json_encode($array);}
其实上传成功的关键是part需要带uploadfile[] ,【 multipartTypedOutput.addPart("uploadfile[]", new TypedFile("", new File(imgPath)));】我在这个地方失败了几十次,无意中看见html网页批量上传的name属性中带了[],我就试了试,果然成功了。

超级简单的Android Studio jni 实现(无需命令行)

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
