Android 发送HTTP GET POST 请求以及通过 MultipartEntityBuilder 上传文件(二)

Android 发送HTTP GET POST 请求以及通过 MultipartEntityBuilder 上传文件第二版

上次粗略的写了相同功能的代码,这次整理修复了之前的一些BUG,结构也大量修改过了,现在应用更加方便点

在 Activity 中的使用方法(这里我还是只写主体部分代码):

            public void onRequest(ZHttpRequest request) throws Exception {

            }

            @Override
            public String onSucceed(int statusCode, ZHttpRequest request) throws Exception {

            }

            @Override
            public String onFailed(int statusCode, ZHttpRequest request) throws Exception {
                return "GET 请求失败:statusCode "+ statusCode;

            @Override

                // 配置要 POST 的数据
                MultipartEntityBuilder builder = request.getMultipartEntityBuilder();
                builder.addTextBody("p1", "abc");
                builder.addTextBody("p2", "中文", 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

                return "POST 请求失败:statusCode "+ statusCode;
            }
        });

        TextView textView = (TextView) findViewById(R.id.showContent);
        String content = "初始内容";
        try {
            if (view.getId() == R.id.doGet) {
                content = get.get("http://www.baidu.com");
                content = "GET数据:isGet: " + (get.isGet() ? "yes" : "no") + " =>" + content;
            } else {
                content = post.post("http://192.168.1.6/test.php");
                content = "POST数据:isPost" + (post.isPost() ? "yes" : "no") + " =>" + content;
            }

        } catch (IOException e) {
            content = "IO异常:" + e.getMessage();
        } catch (Exception e) {
            content = "异常:" + e.getMessage();
        }
        textView.setText(content);
    }

至于服务端我用的 PHP ,只是简单的输出获取到的数据而已

<?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);
