REST API 插件 - 使用正文而不是查询字符串作为参数 [英] REST API plugin - use body instead of query string for parameters
问题描述
我以此为参考在 Struts2 上创建仅 REST 配置:
I'm using this as a reference to create a REST only configuration on Struts2:
https://cwiki.apache.org/confluence/display/WW/REST+插件
我有一个模型，带有几个测试字段的收据:标题、正文.
I have one model, Receipt with a few test fields: title, body.
目前要创建收据，我以这种方式发送请求:
Currently to create a receipt, I send a request in this way:
POST /receipt/?body=new_body&title=new_title
它会为我创建一个包含传入的新正文和标题的收据.
and it creates me a receipt with the new body and title passed in.
这不起作用:
POST /receipt/
{
"body": "new_body",
"title": "new title"
}
这里有一些代码:
struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<bean type="org.apache.struts2.rest.handler.ContentTypeHandler" name="jackson" class="org.apache.struts2.rest.handler.JacksonLibHandler"/>

<constant name="struts.convention.action.mapAllMatches" value="true"/>
<constant name="struts.convention.default.parent.package" value="receipto"/>
<constant name="struts.convention.package.locators" value="controllers,actions"/>
</struts>
ReceiptController.java:
public class ReceiptController implements ModelDriven<Object> {
private ReceiptManager receiptManager = new ReceiptManager();
private String id;
private Receipt model = new Receipt();
private Collection list;
public Object getModel()
{
return (list==null ? model : list);
}
public HttpHeaders create()
{
receiptManager.save(model);
return new DefaultHttpHeaders("create");
}
public HttpHeaders show()
{
model = receiptManager.find(id);
return new DefaultHttpHeaders("show");
}
public HttpHeaders update()
{
receiptManager.save(model);
return new DefaultHttpHeaders("update");
}
public HttpHeaders destroy()
{
model = receiptManager.destroy(id);
return new DefaultHttpHeaders("destroy");
}
public HttpHeaders index()
{
list = receiptManager.list();
return new DefaultHttpHeaders("index").disableCaching();
}
public String getId()
{
return id;
}
public void setId(String id)
{
this.id = id;
}
}
它应该像我想要的那样工作，还是插件就是这样工作的?
Is it supposed to work as I want it to, or is it just how the plugin works?
推荐答案
我猜邮递员是在请求正文中发送 JSON 并设置内容类型 application/json.如果你在堆栈中添加 json 拦截器，Struts 可以解析请求.
I guess that postman is sending JSON in the body of the request and sets the content type application/json. Struts can parse the request if you add json interceptor to the stack.
<interceptor-stack name="myStack">
<interceptor-ref name="json"/>
<interceptor-ref name="myInterceptor"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
The description for "json" interceptor in the JSON Plugin:
如果使用了拦截器，action会从请求中的JSON内容中填充，这些是拦截器的规则:
If the interceptor is used, the action will be populated from the JSON content in the request, these are the rules of the interceptor:
- 内容类型"必须是application/json"
- JSON 内容必须格式正确，语法见 json.org.
- 动作必须有一个公开的setter"；必须填充的字段的方法.
- 支持的填充类型有:Primitives (int,long...String)、Date、List、Map、Primitive Arrays、Other class(稍后会详细介绍)和 Array of Other 类.
- JSON 中要填充到列表或映射中的任何对象都将是 Map 类型(从属性到值的映射)，任何整数都将是 Long 类型，任何十进制数都将是类型Double 和任何 List 类型的数组.
