jQuery的+ WCF。与基本身份验证问题 [英] Jquery+wcf. Problem with basic authentication

问题描述

我的服务保障与基本身份验证在IIS中设置，我尝试从业务数据与jQuery。

My service is secured with basic authentication set in IIS and i am try to get data from service with Jquery.

跨域调用已启用。

我有一个请求头

Host http:\\service.com
User-Agent Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language en-gb,en;q=0.5
Accept-Encoding gzip, deflate
Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7
Connection keep-alive
Origin null
Access-Control-Request-Me... GET
Access-Control-Request-He... authorization
Pragma no-cache
Cache-Control no-cache

响应

Content-Type text/html
Server Microsoft-IIS/7.5
WWW-Authenticate Basic realm="172.27.131.5"
X-Powered-By ASP.NET
Access-Control-Allow-Orig... *
Access-Control-Allow-Head... *

code

Code

 $.ajax({
     headers : {
        "Authorization" : "Basic TVNF3TQtU1BGMjAx6C12bVxzbW4ydHBvaW50OlF3Z5J0eSEyM6Q1"
     },
     type: "GET",
     url: url,
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     success: function(data) {
      alert('ok!');
      formatData(format_type,data);
     },
     error: function(jqXHR, textStatus, errorThrown) {
          alert(textStatus + ' / ' + errorThrown);
     }
  });

我也尝试设置

also i tried to set

 beforeSend : function(xhr) {
      xhr.setRequestHeader("Authorization", "Basic " + Base64.encode(username + ':' + password));
        },

但我有一个错误：

But i have next error:

请求头字段授权不被访问控制，允许报头允许

Request header field Authorization is not allowed by Access-Control-Allow-Headers

我在做什么错了？

推荐答案

尝试添加以下code到在Global.asax在你的WCF项目（仅当在IIS托管工作）：

Try adding the following code to the global.asax in your WCF project (only works when hosted in iis):

protected void Application_BeginRequest(object sender, EventArgs e)
{
    EnableCrossDomainAjaxCall();
}

private void EnableCrossDomainAjaxCall()
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

    if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
    {
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Authorization, Accept");
        HttpContext.Current.Response.End();
    }
}

jQuery的发出一个OPTIONS调用WCF服务，以检查是否允许呼叫。你必须以符合实际的头。您也可以下载一个例子在这里：<一href="http://sameproblemmore$c$c.blogspot.com/2011/10/creating-secure-restfull-wcf-service.html">http://sameproblemmore$c$c.blogspot.com/2011/10/creating-secure-restfull-wcf-service.html.
