经过几天没有任何进展,我需要你的帮助。RestyGWT和基本认证
对于GWT,我试图与我的REST服务器通信,服务器位于不同的URL(需要CORS)。
我的配置:
服务器
- 春季启动1.3.3
客户
- GWT 1.7
- restygwt 2.0.3
服务器端,我认为这是好。
当我在Spring中禁用安全性时,我可以在我的GWT客户端中获取数据。
但是,当我启用它,我总是得到401请求。 REST URL请求直接在Web浏览器中运行(使用其身份验证对话框)。
客户端,我跟了这页:
https://ronanquillevere.github.io/2014/04/11/restygwt-basic-auth.html
这里是我的代码:
这增加凭据头
public class BasicAuthHeaderDispatcherFilter implements DispatcherFilter {
public static final String AUTHORIZATION_HEADER = "Authorization";
@Override
public boolean filter(Method method, RequestBuilder builder) {
try {
String basicAuthHeaderValue = createBasicAuthHeader(
UserCredentials.INSTANCE.getUserName(),
UserCredentials.INSTANCE.getPassword());
builder.setHeader(AUTHORIZATION_HEADER, basicAuthHeaderValue);
} catch (UnsupportedEncodingException e) {
return false;
}
return true;
}
private String createBasicAuthHeader(String userName, String password)
throws UnsupportedEncodingException {
String credentials = userName + ":" + password;
String encodedCredentials = new String(Base64.encode(credentials
.getBytes()), "UTF-8");
GWT.log("encodedCredentials=["+encodedCredentials+"]");
return " Basic " + encodedCredentials;
}
}
的dispacher过滤器:
public class MyDispatcher extends DefaultFilterawareDispatcher {
public MyDispatcher() {
addFilter(new BasicAuthHeaderDispatcherFilter());
}
}
而我的测试呼叫:
@Override
public void onClick(ClickEvent event) {
Defaults.setDispatcher(new MyDispatcher());
UserCredentials.INSTANCE.setUserName("user");
UserCredentials.INSTANCE.setPassword("psswd");
String url = "http://localhost:8080/race";
Resource resource = new Resource(url);
resource.get().send(new JsonCallback() {
@Override
public void onSuccess(Method method, JSONValue response) {
GWT.log(response.toString());
}
@Override
public void onFailure(Method method, Throwable exception) {
GWT.log("Erreur: ", exception);
}
});
}
而现在在网络浏览器开发工具所产生的报头。在Web浏览器
直接:

回答
我注意到两两件事:
- 在GWT头请求,我没有授权值。但是在控制台日志中,我有一条确认过滤器被触发的跟踪。
- 只有在使用firefox时,当我提出请求时,firebug会捕获2个网络窗格,第一个窗口有授权值,但没有答案,第二个窗口是我在上面提到的结果。
感谢您的帮助。
