尽管CORS上有数百个主题,但我找不到我想要的,或者没有什么能帮助我解决问题。
我的情况是
-
我有一个应用程序正在运行http://localhost:8011其需要消耗在另一服务器上运行的一些服务http://localhost:8022
-
我使用jQuery(1.7.1)ajax将另一台服务器中的服务调用为
var Request = '<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<TicorRequest xmlns="urn:Ticor" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ServiceName="Quote_Gen">
<WorkDocuments>
<Premium_details id="Premium_details_id_1">
<quote_components id="Quote_components_id_1">
<AAC_Membership>400000</AAC_Membership>
<Adjustment_fee>2000</Adjustment_fee>
</quote_components>
</Premium_details>
</WorkDocuments>
</TicorRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>';
var TicorService = $.ajax({
type: "POST",
processData: false,
url: "http://localhost:8022/axis/services/Ticor",
data: Request,
beforeSend: function(xhr){xhr.setRequestHeader('SOAPAction', 'urn:Ticor'); },
xhrFields: { withCredentials: false },
contentType: "text/xml; charset="utf-8"",
crossDomain: true,
dataType: "xml",
success: function(data, status, req)
{
alert(data);
},
error: function(XMLHttpRequest, textStatus, errorThrown)
{
alert(errorThrown);
},
complete: function(XMLHttpRequest, textStatus)
{
}
});
- 但我在Chrome中收到了以下错误消息
XMLHttpRequest无法加载http://localhost:8022/axis/services/Ticor.对飞行前请求的响应未通过访问控制检查:请求的资源上不存在"access control Allow Origin"标头。原点'http://localhost:8011因此不允许访问响应的HTTP状态代码为200。
- 然后,我尝试在Tomcat服务器的web.xml文件中添加以下内容(该文件为7.0.42)
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.origins</param-name>
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.headers</param-name>
<param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
</init-param>
<init-param>
<param-name>cors.exposed.headers</param-name>
<param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
</init-param>
<init-param>
<param-name>cors.support.credentials</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>cors.preflight.maxage</param-name>
<param-value>10</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- 添加以上内容后,我得到了相同的错误消息,但带有。响应的HTTP状态代码为403
你能告诉我我在这里缺了什么吗?还是其他选择?
我遇到了同样的问题,发现在chrome中向localhost上的不同源源发出请求时总是会出现此错误。我试着在IE中运行,然后运行得很好。我在chrome中运行的解决方案是禁用chrome上的CORS-安全:
RUN-->Chrome.exe--禁用网络安全
这里有一个引用,指出chrome不支持本地主机处理CORS请求,请参阅链接:https://bugs.chromium.org/p/chromium/issues/detail?id=67743
另见stackoverflow帖子:致命CORS当http://localhost是的原点
您的javascript执行xhr.setRequestHeader('SOAPAction', 'urn:Ticor');
以发送标头SOAPAction
。但是这个不在cors.allowed.headers中。你必须修改web.xml中的过滤器配置:
<init-param>
<param-name>cors.allowed.headers</param-name>
<param-value>Content-Type,X-Requested-With,Accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers,SOAPAction</param-value>
</init-param>
更新
将参数值accept
更改为Accept
。
