从Android发送一个HTTP请求到一个rails服务器

我尝试发送一个xml文件，在android中的http到一个rails服务器。从Android发送一个HTTP请求到一个rails服务器

我的Android发送码：

String link = "http://10.0.2.2:3000/export"; 

    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost(link); 

    try { 
     String xmlFile = createXml(locationList); 
     StringEntity entity = new StringEntity(xmlFile, "UTF-8"); 
     httppost.setEntity(entity); 
     httppost.addHeader("Content-Type", "application/xml"); 
     HttpResponse response = httpclient.execute(httppost); 
     Log.d("response reason phrase", "" 
       + response.getStatusLine().getReasonPhrase()); 
     Log.d("response content", "" 
       + response.getStatusLine().getStatusCode()); 
    } catch (ClientProtocolException e) { 
     Log.d("exception", e.getMessage()); 
    } catch (IOException e) { 
     Log.d("exception", e.getMessage()); 
    }

在铁轨我创建了一个控制器的方法来监听输出 - 链接：

def export 

begin 
    result = Net::HTTP.get(URI.parse("http://localhost:3000/export")) 
    MyLog.debug "#{result}" 
    xml_doc = Nokogiri::XML(result) 


    locations = xml_doc.xpath("//location") 

    if locations.count > 0 
    training = Training.create! 

    locations.each do |xml_location| 
     location = Location.new 
     location.latitude = xml_location.xpath("latitude").text 
     location.longitude = xml_location.xpath("longitude").text 
     location.training_id = training.id 
     location.save! 
    end 
    end 
    # end 
rescue TimeoutError => e 
    MyLog.debug "timeout #{e}" 
end 
end

，我被迫创建export.html。 ERB，其中包含以下内容：

Nothing to see

我的routes.rb包含此：

match 'export' => 'Trainings#export', as: "export", :via => [:get, :post]

但是，如果我用我的应用程序立即请求到服务器，我看到在我的CMD如下：

Started POST "/export" for 127.0.0.1 at 2013-01-15 22:47:59 +0100 
    Connecting to database specified by database.yml

    Parameters: {"training"=>{"location"=>[{"longitude"=>"60.0", 
    "latitude"=>"60.0"}, {"longitude"=>"59.9999", "latitude"=>"60.0"}, 
    {"longitude"=>"59.99995", "latitude"=>"59.9999"}]}}

    Completed 200 OK in 61633ms (Views: 576.0ms | ActiveRecord: 0.0ms)

在此之后它不是更可能访问到我的服务器和我会看到在控制台始终如下：

我的XML的解析是幸运的工作，因为我已经在复制方法创建的XML文件进行了测试，但希望你能帮助我理解我的问题:) 。我搜索了很多小时，但我没有，这帮助我解决了我的问题。

幸运的是，我通过朋友的提示修复了这个问题。

我的误解是，控制器方法通常会听取导出链接，所以我有两次listend。

所以溶液删除HTTP GET：

 result = Net::HTTP.get(URI.parse("http://localhost:3000/export"))

然后，我不得不删除XML解析，因为我得到了一个哈希信息
