一、Post提交 並可以實現多檔案上傳

// 建立DefaultHttpClient對象        HttpClient httpclient = new DefaultHttpClient();        // 建立一個HttpGet對象        HttpPost post = new HttpPost(realUrl);                MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);                if (params != null) {            for (String key : params.keySet()) {                if (params.get(key) instanceof File) {                    // If the key equals to "image", we use FileBody to                    // transfer the data                    entity.addPart(key, new FileBody((File) params.get(key)));                } else {                    // Normal string data                    if (params.get(key) != null) {                        entity.addPart(key, new StringBody(params.get(key).toString(), java.nio.charset.Charset.defaultCharset())); //此處防止亂碼                    }                }            }        }        post.setEntity(entity);        // 擷取HttpResponse對象        HttpResponse response = httpclient.execute(post);        // 判斷是否連結成功        if (response.getStatusLine().getStatusCode() == 200) {            // 實體轉換為字串            String content = EntityUtils.toString(response.getEntity(), HTTP.UTF_8);            LogUtil.i("response:" + content);            return new JSONObject(content);        } else {            LogUtil.i("realurl: " + getCode(response.getStatusLine().getStatusCode()));        }

 

二、Get方式

// 建立DefaultHttpClient對象        HttpClient httpclient = new DefaultHttpClient();        // 執行個體化HTTP方法          HttpGet get = new HttpGet();          get.setURI(new URI(realUrl));          // 擷取HttpResponse對象        HttpResponse response = httpclient.execute(get);        // 判斷是否連結成功        if (response.getStatusLine().getStatusCode() == 200) {            // 實體轉換為字串            String content = EntityUtils.toString(response.getEntity(), HTTP.UTF_8);            LogUtil.i("response:" + content);            return new JSONObject(content);        } else {            LogUtil.i("realurl: " + getCode(response.getStatusLine().getStatusCode()));        }
