Extension:DonationInterface/zh

DonationInterface呈现付款表格，并提供recharinary机制，用于通过各种支付网关收集和跟踪付款.

概述
捐赠接口扩展所做的大部分工作都是与支付网关进行通信. 我们还提供了一个面向用户的表单层，用于接受捐赠.

配置
在LocalSettings.php中include以下内容：

接下来，定义要启用的网关.

例如，以下内容将打开所有当前网关和扩展 （TODO:文档默认值和更新. ）:

在此之后，TODO确保为您打算使用的每个网关定义帐户信息，例如：

重要信息:

DonationInterface以一种特殊的方式搜索全局.

网关使用的任何DonationInterface全局都可以被分配一个特定于该网关的值，或者是整个扩展的默认值（如果两者都存在，则细节将覆盖默认值）.

要为网关全局分配扩展范围的默认值，只需将全局变量名称中的网关前缀换成“wgDonationInterface”即可.

例如：要在默认情况下为整个DonationInterface扩展打开syslogging，而不仅仅是payflow pro网关，请更改以下内容：

到这:

Syslog现在将为所有网关启用，除非您使用特定于网关的全局变量关闭它们.



额外配置
要创建自定义捐赠筛选规则，请在LocalSettings.php文件中设置$wgCustomFiltersRefRules和$wgCustomFilter SrcRules全局变量.

这些数组应设置为关联数组，将正则表达式模式与风险评分数字配对，例如：

Define Globals in LocalSettings.php
While there are many more globals available to override, the following probably need to be defined in LocalSettings if you want DonationInterface to actually work.

Global variables are defined in DonationInterface.php.

实现


代码
Very generally speaking, the process of completing a donation goes like this:

This form will be controlled by a gateway-specific unlisted special page of a class descended from the GatewayForm class. On construction, the gateway adapter will gather, normalize, and validate any relevant data in $wgRequest. All gateways use the same class, DonationData, to accomplish this task. Doing this means that all the data is subject to the same normalization and validation processes, no matter who's asking for it or where it came from. As every payment gateway has its own set of rules (and in some cases, completely different transaction types that are not directly analogous to anything else in any of the other gateways) it is up to the adapter to sort all of that out internally, and only expose functionality to the controlling object in such a way that it seems more or less universal across all possible adapter objects. This could be a "Thank you" page, an error displayed on the submitted form prompting the user to try again in a meaningful way, or a more fatal sort of error page.
 * The donor is sent to a donation form that is already tied to a specific payment gateway.
 * The extended GatewayForm class will instantiate its gateway adapter.
 * The controlling GatewayForm child class will then use the gateway adapter to determine where the user is in the donation process, and if appropriate (no errors on validation, all data present, no strangeness with the edit token or session, that sort of thing), use that same gateway adapter to interact with the remote payment servers in order to take the next step in the donation process.
 * After having the gateway adapter perform one or more transactions with the remote payment gateway, the controlling object would then use the gateway to determine what happened, and display appropriate results to the prospective donor.

GatewayAdapter class
(DonationInterface/gateway_common/gateway.adapter.php) - This is an abstract class that takes care of everything a general gateway needs to do. It it also supposed to yell at you rather loudly if you fail to define any of the particulars that a gateway needs, in order to be able to do anything worthwhile.

GatewayForm
(DonationInterface/gateway_common/GatewayForm.php) - A class that extends UnlistedSpecialPage. This will take care of all the not-gateway-specific functionality necessary to present a donation form to a user, and get the results. Of particular interest are the mechanisms for displaying the requested form (or not), handling some of the more universal aspects of form validation, and fetching data that could be used by the specified forms (as in, a list of countries and their codes for a country drop-down).

Classes that inherit from these will be specific to a particular payment gateway. As such, they will be located in a folder named something like DonationInterface/[name]_gateway/.

Most adapters will implement GatewayForm for two routes: the initial payment form, and a result switcher page.

The initial payment form is responsible for rendering a form with inputs for the mandatory data to be collected. Alternatively, some gateways such as GlobalCollect will render an iframed form hosted by the payment processor, and others such as PayPal and Amazon will transparently redirect to the processor unless the donation information (currency and amount) are invalid and must be corrected.

The result switcher is usually not responsible for confirming payment or performing further authorization, it simply routes the donor to either the Thank You or Failure pages, depending on approximate responses from the processor.

DonationData class
(DonationInterface/gateway_common/DonationData.php) - This class is intended to handle everything that we are likely to want to do with Donation Data. It should load the data in a consistent way from any appropriate source (including a test), saves relevant Contribution Tracking data, generates data we always need to generate (like order IDs), normalizes everything, and hands it back to the gateway. Classes inheriting from GatewayAdapter will instantiate a DonationData class on creation. The GatewayAdapter child classes should only ever use data that has come through the DonationData class. It also handles edit tokens.

DataValidator
All data is first normalized by DonationData, and is then validated. If data fails validation, all processing is halted and the donor is redirected back to the form where they can correct any errors. Messages are displayed to guide the user through the corrections. TODO: make messages human-readable, attach to fields rather than pop-up, etc.

The gateway adapter is consulted for some of these validations, for example a lower and upper threshold for valid donation amounts, and accepted currencies.

Defining A New Gateway Adapter
GatewayAdapter extends the GatewayType interface. TODO: Here is a quick guide to defining the functions in GatewayType.

测试
Unit tests can be found in the tests directory of the DonationInterface extension.

To run unit tests go to the mediawiki-core directory, then under tests/phpunit:

Composer
Whenever  changes, you must run   to refresh the contents of vendor/.

For WMF production, vendor is deployed on the "deployment" branch as a git submodule. You must  the package ".git" directories when committing new packages, otherwise they will be treated as misshapen, nested submodules and you don't want to go there.

路线图
Some things we want to do:

(✅) (✅) : (✅)
 * Decouple presentation layer from controllers and payments backend
 * Kill RapidHTML and use a mainline templating engine
 * Consolidate forms into a single universal form, with boolean params that control block visibility and available features
 * Decouple payment processing from the MediaWiki framework, so it can be used as a standalone library
 * Provide access to the payments library inside of Drupal, to enable refunds, cancellation, and status retrieval from CiviCRM
