消费ASP.NET Web服务从PhoneGap的 [英] Consuming ASP.NET Web Service From Phonegap

问题描述

我一直在试图使用来自一个PhoneGap的，Android应用程序写在ASP.NET Web服务，但我似乎犯了一个错误莫名其妙的地方。

Hi, i've been trying to consume a Web Service written in ASP.NET from a phonegap-android app but i seem to be making a mistake somehow somewhere.

值得一提的是，这个失败，当我从Eclipse中的Andr​​oid模拟器中运行它。我已经尝试从Web浏览器相同的code和它工作得很好。

It's worth mentioning that this fails when i run it on the android emulator from eclipse. I've already tried the same code from a web browser and it works just fine.

以下是部分的的index.html 的这相关的问题

Here's the part of Index.html that's relevant for the question

/* Here i declare 'webServiceURL' which holds the path to the service that's
   hosted at 10.0.0.174 (WLAN ip of my computer). I use this instead of 127.0.0.1
   because on a mobile phone localhost points to the phone itself. */

// Here i declare 'datos' which are the parameters sent to the web service method 

$.ajax({
  url: webServiceURL + "InicioSesion",
  type: "POST",
  contentType: "application/json; charset=utf-8",
  data: JSON.stringify(datos),                    
  dataType: 'json',
  beforeSend: function() {$.mobile.loading('show')},
  complete: function() {$.mobile.loading('hide')},
  success: function (data, textStatus, jqXHR) {
    // Here i do stuff with 'data'
  },
  error: function (jqXHR, textStatus, errorThrown) {
    // Here i print errors
  },
)};

访问权限原产地加入到PhoneGap的的的config.xml 的

<access origin="*"/>

修改到的的web.config 的ASP.NET Web服务的

Modifications to the web.config of the ASP.NET Web Service

<system.webServer>
  <httpProtocol>
   <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
   </customHeaders>
  </httpProtocol>
</system.webServer>

我要面对错误是，当我设置的dataType到JSON（这是我期待）Ajax请求失败，并打印textStatus'给我的 ParserERROR 的

所以，我想用'的dataType作为文，而不是JSON，看看是否有什么错误的Web服务的响应，我意识到，问题是，反应是NULL。

So i tried using 'dataType' as 'text' instead of 'json' to see if there was something wrong with the Web Service response, and i realized that the problem was that the response was NULL.

记得我提到的，这个code完美的作品上的Web浏览器，它无法在PhoneGap的应用程序在Android模拟器中运行。

REMEMBER what i mentioned, this code works perfectly on a Web Browser, it fails on the phonegap app running from the android emulator.

如果有人带着几分使用PhoneGap的消费ASP.NET Web服务的经验可以请帮助我！我不知道我失踪或者做错了什么！我一直在这2天，现在我只是无法找到解决的办法！

If anybody with a bit of experience using phonegap to consume an ASP.NET Web Service could please help me!. I have no idea of what i'm missing or doing wrong!. I've been working on this for 2 days by now and i just can't find a solution!

推荐答案

我已经想通了这个错误我是做！

在访问权限原产地加入到PhoneGap的的的config.xml 的我把：

On the access origin permission added to phonegap config.xml i was putting:

<access origin="*"/>

这是不正确的！正确的方式把它与一个点（'。'）星号之前（*）：

That's incorrect!, the right way to put it is with a dot ('.') before the asterisk ('*'):

<access origin=".*"/>

这就是它！问题解决了！
