Android 發送HTTP GET POST 請求以及通過 MultipartEntityBuilder 上傳文件(二)
Android 發送HTTP GET POST 請求以及通過 MultipartEntityBuilder 上傳文件第二版
上次粗略的寫了相同功能的代碼,這次整理修複了之前的一些BUG,結構也大量修改過了,現在應用更加方便點
https://blog.csdn.net/zhouzme/article/details/18940279
直接上代碼了:

在 Activity 中的使用方法(這裏我還是隻寫主體部分代碼):
MainActivity.java
public void doClick(View view) { ZHttpRequest get = new ZHttpRequest(); get .setCharset(HTTP.UTF_8) .setConnectionTimeout(5000) .setSoTimeout(5000); get.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() { @Override public void onRequest(ZHttpRequest request) throws Exception { } @Override public String onSucceed(int statusCode, ZHttpRequest request) throws Exception { return request.getInputStream(); } @Override public String onFailed(int statusCode, ZHttpRequest request) throws Exception { return "GET 請求失敗:statusCode "+ statusCode; } }); ZHttpRequest post = new ZHttpRequest(); post .setCharset(HTTP.UTF_8) .setConnectionTimeout(5000) .setSoTimeout(10000); post.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() { private String CHARSET = HTTP.UTF_8; private ContentType TEXT_PLAIN = ContentType.create("text/plain", Charset.forName(CHARSET)); @Override public void onRequest(ZHttpRequest request) throws Exception { // 設置發送請求的 header 信息 request.addHeader("cookie", "abc=123;456=愛就是幸福;"); // 配置要 POST 的數據 MultipartEntityBuilder builder = request.getMultipartEntityBuilder(); builder.addTextBody("p1", "abc"); builder.addTextBody("p2", "中文", TEXT_PLAIN); builder.addTextBody("p3", "abc中文cba", TEXT_PLAIN); if (picPath != null && ! "".equals(picPath)) { builder.addTextBody("pic", picPath); builder.addBinaryBody("file", new File(picPath)); } request.buildPostEntity(); } @Override public String onSucceed(int statusCode, ZHttpRequest request) throws Exception { return request.getInputStream(); } @Override public String onFailed(int statusCode, ZHttpRequest request) throws Exception { return "POST 請求失敗:statusCode "+ statusCode; } }); TextView textView = (TextView) findViewById(R.id.showContent); String content = "初始內容"; try { if (view.getId() == R.id.doGet) { content = get.get("https://www.baidu.com"); content = "GET數據:isGet: " + (get.isGet() ? "yes" : "no") + " =>" + content; } else { content = post.post("https://192.168.1.6/test.php"); content = "POST數據:isPost" + (post.isPost() ? "yes" : "no") + " =>" + content; } } catch (IOException e) { content = "IO異常:" + e.getMessage(); } catch (Exception e) { content = "異常:" + e.getMessage(); } textView.setText(content); }
其中 picPath 為 SD 卡中的圖片路徑 String 類型,我是直接拍照後進行上傳用的

布局頁麵
activity_main.xml
<LinearLayout xmlns:andro android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <Button android: android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:layout_marginBottom="10dp" android:text="GET請求" android:onClick="doClick" /> <Button android: android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:layout_marginBottom="10dp" android:text="POST請求" android:onClick="doClick" /> <Button android: android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:layout_marginBottom="10dp" android:text="拍照" android:onClick="doPhoto" /> <TextView android: android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="10dp" /> <ImageView android: android:layout_width="fill_parent" android:layout_height="250dp" android:scaleType="centerCrop" android:src="@drawable/add" android:layout_marginBottom="10dp" /> </LinearLayout> </ScrollView> </LinearLayout>
至於服務端我用的 PHP ,隻是簡單的輸出獲取到的數據而已
<?php echo 'GET:<br>'. "\n"; //print_r(array_map('urldecode', $_GET)); print_r($_GET); echo '<br>'. "\n". 'POST:<br>'. "\n"; //print_r(array_map('urldecode', $_POST)); print_r($_POST); echo '<br>'. "\n". 'FILES:<br>'. "\n"; print_r($_FILES); echo '<br>'. "\n". 'COOKIES:<br>'. "\n"; print_r($_COOKIE);
