我嘗試發送一個xml文件,在android中的http到一個rails服務器。從Android發送一個HTTP請求到一個rails服務器
我的Android發送碼:
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());
}
在鐵軌我創建了一個控制器的方法來監聽輸出 - 鏈接:
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
,我被迫創建export.html。 ERB,其中包含以下內容:
Nothing to see
我的routes.rb包含此:
match 'export' => 'Trainings#export', as: "export", :via => [:get, :post]
但是,如果我用我的應用程序立即請求到服務器,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

在此之後它不是更可能訪問到我的服務器和我會看到在控制檯始終如下:

我的XML的解析是幸運的工作,因爲我已經在複製方法創建的XML文件進行了測試,但希望你能幫助我理解我的問題:) 。我搜索了很多小時,但我沒有,這幫助我解決了我的問題。
