使用的PhoneGap和jQuery不起作用跨域请求 [英] Cross-domain requests using PhoneGap and jQuery doesn't work
问题描述
我创建一个PhoneGap的应用程序为Android。要获取数据（远程）服务器我做一个REST调用使用jQuery的$。阿贾克斯（）函数。有几件事你必须知道的：
I'm creating a PhoneGap app for Android. To get data from the (remote) server I make a REST call using jQuery's $.ajax() function. There are a few things you must know:
- 呼叫的类型必须是POST
- 在服务器期待JSON数据（至少用户名和密码）
- 服务器返回JSON数据
在code：
function makeCall(){
var url = "http://remote/server/rest/call";
var jsonData ='{"username":"'+$('#username').val()+'","password":"'+$('#password').val()+'"}';
$.ajax({
headers: {"Content-Type":"application/json; charset=UTF-8"},
type: "POST",
url: url,
data: jsonData,
dataType: "json",
success: succesFunction,
error: errorFunction
});
}
不过，这也不行。当我使用Firebug看到服务器的回应，并没有什么。随着TcpTrace我可以看到请求的报头。代替一个预期POST方法的，有一个OPTIONS方法，用一些奇怪头添加
But, this doesn't work. When I use Firebug to see the servers response, there is nothing. With TcpTrace I can see the headers of the request. Instead of an expected POST method, there is an OPTIONS method, with some strange headers added.
OPTIONS /remote/server/rest/call HTTP/1.1
Host: localhost:8081
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: nl,en-us;q=0.7,en;q=0.3
Accept-Encoding: gzip, deflate
Connection: keep-alive
Origin: null
Access-Control-Request-Method: POST
Access-Control-Request-Headers: content-type
Pragma: no-cache
Cache-Control: no-cache
我知道它是与做跨域请求，但我不知道如何解决这个问题。我试了几件事情来解决它，但没有结果：
I know it has something to do with doing cross-domain requests, but I don't know how to solve the problem. I tried a few things to fix it, but with no result:
- 使用在JSON代替JSONP
- 尝试使用跨域资源共享（CORS）
这个问题也有一些做同样的原产地政策，但这并不适用于该文件：//协议的PhoneGap是使用加载本地HTML文件
The problem has also something to do with same origin policy, but this does not apply to the file:// protocol PhoneGap is using to load a local html file.
在我的AndroidManifest.xml文件，选项
In my AndroidManifest.xml file, the option
<uses-permission android:name="android.permission.INTERNET" />
设置。
我想解决这个问题2现在天，但没有结果到现在。这甚至可能做什么？你有什么建议给我，所以我可以继续前进？
I'm trying to fix this for 2 days now, but no result till now. Is this even possible to do? Do you have any tips for me so I can move on?
在此先感谢！
推荐答案
我由我自己解决了这个问题。问题是地处网址，在那里我有添加域。我改变了
I solved the problem by myself. The problem is located in the url, where I have to add a domain. I changed
VAR URL =HTTP：//远程/服务器/ REST /呼叫;
到
VAR URL =http://remote.mydomain.com/server/rest/call;
和它的作品！
我认为第一个URL应该工作，因为它的工作原理与确切相同的URL，并设置一个iPhone应用程序。它也是东西做一个双重防火墙（Windows和ESET防火墙），我关闭了Windows防火墙。
I assumed the first url should work because it works on an iphone app with exact the same url and settings. It has also something to do with a double firewall(Windows and ESET firewall) where I shut down the Windows firewall.
无论如何，感谢您的回答！
Anyway, thanks for your answers!
