如何将Android http发布到Node.js

Question

我想从Android向Node.js服务器发送一个简单的HTTP POST请求。 谁能告诉我我在做什么错？

Android代码：

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://54.68.139.250/bscreateuser");

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username", "hellomoto"));
        nameValuePairs.add(new BasicNameValuePair("password", "pswd"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

Node.js代码：

 app.get('/bscreateuser', function(request, response) { process.stdout.write("Attempted to create a user."); bscreateUser(request.query.username, request.query.password); response.send('-- BS -- User Created! username: ' + request.query.username + ' password: ' + request.query.password); }); function bscreateUser(username, password) { messageBody = 'create_user("' + username + '","' + password + '")'; queueUrl = DAO_QUEUE_URL; // sys.puts("--- going for BS ---"); sendSQSMessage(JSON.stringify(messageBody), queueUrl); } 

Answer 1

在node.js代码中，您正在使用

app.get('/bscreateuser', ...

相反，您需要使用post方法

app.post('/bscreateuser', ...

并访问所需的变量，如下所示：

request.body.varname

Answer 2

您进行GET路由，如果要发布数据，则必须将其发布

节点代码

app.post(..

和参数可能会得到

request.body.username or request.body.password
