本文介绍了cURL和Siteminder身份验证的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我们正在尝试使用cURL自动执行某些数据收集.不幸的是，源系统受到siteminder的保护. (Web访问管理软件).

We are trying to automate certain data collection using cURL. Unfortunately the source system is protected by siteminder. (Web Access Management Software).

我尝试使用普通命令

curl -kL -o my_data.xml -u username:password https://example.com/location/of/file

(尽管用户名和密码正确，但显示错误)

(though the username & password are correct, its displaying error)

错误

HTTP Status 401 - 
This request requires HTTP authentication ().

有什么想法如何从Siteminder身份验证页面连接和获取数据?

Any idea how to connect and fetch data from a siteminder authenticated page?

欢呼

推荐答案

使用SiteMinder引用查找login.fcc模板所需的必需参数:

Use the SiteMinder reference to find the required parameters needed for the login.fcc template:

以下是SiteMinder请求/响应的示例:

Here is an example SiteMinder request/response:

下图中列出的隐藏输入用于保持凭证收集器的状态:

The hidden inputs listed in the following figure are used to hold state for the credential collectors:

FCC可以解释许多调用非标准处理的特殊名称/值对(@directives).特殊的@指令及其含义如下:

An FCC can interpret a number of special name/value pairs (@directives) that invoke nonstandard processing. The special @directives and their meanings follow:


Special Name/Value Pairs

postpreservationdata
Data that a user submits through a post request.

username
Name for the login user name.

password
Password to perform the login.

target
Resource to access after login.

smheaders
Colon separated list of response names to include in the namespace. The colon separated list must contain an entry for each header that you want to include in a transaction. For example, if you want to pass the value of header1 and header2 as part of a transaction, include the following line in your FCC:

@smheaders=header1:header2

smerrorpage
If there is an error on a POST to the custom form, the user browser is redirected to this page. If this special value is not specified in a .fcc file, the system uses the .unauth file that is associated with the .fcc file as the error page.

smretries
Specifies the maximum number of login attempts allowed. If you set this directive to 0, the number of retries is unlimited. If you set the number to 1 or greater, that is the number of retries allowed.

Note: If users log in using a POST to an .fcc form, it may appear that the user is given additional attempts to log in beyond the value of the smretries directive. However, the user is allowed access only if valid credentials are entered in the number of attempts that smretries specifies.

smpasswordfcc
Determines whether data is posted from the Password Services FCC file or from a different FCC file.

Default: 1

Important! We recommend that you use the default value. The SafeWord authentication scheme may not work properly if the default value is changed.

smusrmsg
Text that describes why the user was challenged / failed to login.

smauthreason
Reason code that is associated with a login failure.

smsavecreds
Set to Yes to save user credentials in a persistent cookie on the user browser.

smsave
Colon separated list of names to be saved as persistent cookies.

save
Another name for smsave.

smtransient
Colon separated list of names to be saved as transient cookies.

smagentname
Specifies the agent name that is supplied to the Policy Server when a user enters credentials and submits the form for authentication. If the Agent parameter, FCCCompatMode=NO, specify a value using this directive.

smlogout
Logs a user out of the system, similar to the LogoffUri parameter. By placing @smlogout=true in your .fcc template, the FCC logs a user out and redirect the user to the target. As such, the @smlogout directive is typically used with the @target directive (@target=).

urlencode(name)
Replaced by the URL encoded value of the named variable.

Note: If you expect the additional attributes or the Password to contain special characters (" . & = + ? ; / : @ = , $ %), URL-encode each additional attribute value in the .fcc template file. The template uses US-ASCII encoding.
urldecode(name)
Replaced by the URL decoded value the named variable.

Note: The "sm" prefix for name/value pairs is reserved for additional special names that the system requires. When creating names for your login page do not use the "sm" prefix.

Localization Name/Value Pairs
The .fcc template files include two localization parameters:

smlocale
Used to determine the language used in the HTML forms that collect user information or display status messages.

The value that is paired with smlocale corresponds to part of the name of a localization properties file. The localization properties file contains IDs mapped to text strings in the specified language.

smlocale values have the following format:

COUNTRY-LANGUAGE

For example, the value for smlocale for United States English is:

SMLOCALE=US-EN

smenc
Contains information that tells the browser what language encoding to use. Changing the default value for this variable overrides the encoding set in the following META tag:

.fcc文件至少必须收集以下内容:

At a minimum, an .fcc file must collect the following:

用户名

密码

目标

重要！如果用户将向使用凭据收集器的身份验证方案保护的资源提交发布请求(请参见下图)，请使用postpreservationdata输入.否则，用户尝试发布到请求的资源的数据将丢失.

Important! If users will be submitting post requests to a resource protected by an authentication scheme that uses a credential collector (see the following figure), use the postpreservationdata input. Otherwise, data that users attempt to post to the requested resource will be lost.
