新浪微博Android 客户端通过HTTP POST发布图片和文字源代码
1、发送图片+文字
要特别注意,图片的文件名要为 pic 才会被新浪接收。
- Map map = new HashMap();
- map.put("source", "appkey");//改成自己的key
- map.put("status", txt);
- postImg("http://api.t.sina.com.cn/statuses/upload.json",map,Environment.getExternalStorageDirectory()+ "/temp.jpg"
- ,"帐号名字","密码");
- /**
- * 直接通过HTTP协议提交数据到服务器,实现表单提交功能
- * @param actionUrl 上传路径
- * @param params 请求参数 key为参数名,value为参数值
- * @param filename 上传文件
- * @param username 用户名
- * @param password 密码
- */
- private void postImg(String actionUrl,Map<String, String> params, String filename,String username,String password) {

- URL url = new URL(actionUrl);
- HttpURLConnection conn = (HttpURLConnection) url.openConnection();

- //NameValuePair实现请求参数的封装

- params.add(new BasicNameValuePair("source", "4016954419"));
- params.add(new BasicNameValuePair("status", status));
- try
- {
- //添加请求参数到请求对象
- httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
- httppost.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
- String data=username+":"+password;
- httppost.addHeader("Authorization","Basic "+new String(SecBase64.encode(data.getBytes())));
- httppost.addHeader("Content-Type", "application/x-www-form-urlencoded");
- //发送请求并等待响应
- HttpResponse httpResponse = new DefaultHttpClient().execute(httppost);
- //若状态码为200 ok
- if(httpResponse.getStatusLine().getStatusCode() == 200)
- {
- //读返回数据
- //String strResult = EntityUtils.toString(httpResponse.getEntity());
- new AlertDialog.Builder(Main.this)
- // Main.this视情况而定,这个一般是指当前显示的Activity对应的XML视窗。
- .setTitle("")// 设置对话框的标题
- .setPositiveButton("确定",// 设置对话框的确认按钮
- new DialogInterface.OnClickListener() {// 设置确认按钮的事件
- public void onClick(DialogInterface dialog, int which) {
- }})
- .setMessage(" 发布成功 ")// 设置对话框的内容
- .show();
- }
- else if(httpResponse.getStatusLine().getStatusCode() == 400)
- {
- new AlertDialog.Builder(Main.this)
- // Main.this视情况而定,这个一般是指当前显示的Activity对应的XML视窗。
- .setTitle("")// 设置对话框的标题
- .setPositiveButton("确定",// 设置对话框的确认按钮
- new DialogInterface.OnClickListener() {// 设置确认按钮的事件
- public void onClick(DialogInterface dialog, int which) {
- }})
- .setMessage(" 发布失败 /n 不可连续发布相同内容 ")// 设置对话框的内容
- .show();
- }
- }
- catch (ClientProtocolException e)
- {
- e.printStackTrace();
- et.setText(et.getText()+" Error1:"+e.getMessage());
- }
- catch (IOException e)
- {

- }
