前面我们学习了使用get去请求了文本内容，我们获取到了json数据，并且解析，显示到UI上。

请求文本

接下来我们看看如何去提交文本。

本文为网络编程系列文章，关于权限和网络配置看前面的文章。

Android开发之网络和多媒体

接口地址

/post/comment

提交内容：

{
	"articleId":"234123",
	"commentContent":"这是评论内容"
}

请求代码

    public void postRequest(View view) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                OutputStream outputStream = null;
                InputStream inputStream = null;
                try {
                    URL url = new URL(BASE_URL + "/post/comment");
                    HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
                    httpURLConnection.setRequestMethod("POST");
                    httpURLConnection.setConnectTimeout(10000);
                    httpURLConnection.setRequestProperty("Content-Type","application/json;charset=UTF-8");
                    httpURLConnection.setRequestProperty("Accept-Language","zh-CN,zh;q=0.9");
                    httpURLConnection.setRequestProperty("Accept","application/json, text/plain, */*");
                    CommentItem commentItem = new CommentItem("234134123","你的文章写得也太好了！");
                    Gson gson = new Gson();
                    String jsonStr = gson.toJson(commentItem);
                    byte[] bytes = jsonStr.getBytes("UTF-8");
                    Log.d(TAG,"jsonStr length -- > " + bytes.length);
                    httpURLConnection.setRequestProperty("Content-Length",String.valueOf(bytes.length));
                    //连接
                    httpURLConnection.connect();
                    //把数据给到服务
                    outputStream = httpURLConnection.getOutputStream();
                    outputStream.write(bytes);
                    outputStream.flush();
                    //拿结果
                    int responseCode = httpURLConnection.getResponseCode();
                    if(responseCode == HttpURLConnection.HTTP_OK) {
                        inputStream = httpURLConnection.getInputStream();
                        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
                        Log.d(TAG,"result -- > " + bufferedReader.readLine());
                    }
                } catch(Exception e) {
                    e.printStackTrace();
                } finally {
                    IOUtils.ioClose(inputStream);
                    IOUtils.ioClose(outputStream);
                }
            }
        }).start();
    }

使用GsonFormat来生成以下类：

public class CommentItem {
    public CommentItem(String articleId,String commentContent) {
        this.articleId = articleId;
        this.commentContent = commentContent;
    }

    private String articleId;

    private String commentContent;

    public String getArticleId() {
        return articleId;
    }

    public void setArticleId(String articleId) {
        this.articleId = articleId;
    }

    public String getCommentContent() {
        return commentContent;
    }

    public void setCommentContent(String commentContent) {
        this.commentContent = commentContent;
    }
}

如果不会使用GsonFormat的，或者不会安装插件的同学，可以去看看AndroidStudio的课程

AndroidStudio奇淫技巧-掌握以后可以提升效率，还可以装逼

然后跑起来吧！

运行结果

result -- > {"success":true,"code":10000,"message":"评论成功:你的文章写得也太好了！","data":null}

后台服务器下载请看视频，或者跟着说明进行配置。
