带有 xml 的 Java PostMethod

Java PostMethod with xml

提问by Bot

I am trying to post XML data as a body to a REST api.

我正在尝试将 XML 数据作为主体发布到 REST api。

I have a method that creates the request called doREST.

我有一个方法可以创建名为 doREST 的请求。

String url = null;
        HttpMethod method;
        LOG.info("QUERY: " + query);
        if (StringUtil.isEmpty(query)) {
            url = BuildRequestURL("/issues.ashx/issues/mywork");
            method = doREST(url, false);
        } else {
            url = BuildRequestURL("/issues.ashx/issues/filters");
            //method = doREST(url, true);
            method = doREST(url, true);
            String xml = "<IssuesFilterEN>" +
                    "<IssueID>" + query + "</IssueID>" +
                    "</IssuesFilterEN>";
            RequestEntity entity = new StringRequestEntity(xml,"text/xml; charset=iso-8859-1", null);


method.setRequestEntity(entity);
    }

and the doREST method

和 doREST 方法

private HttpMethod doREST(String request, boolean post) throws Exception {
        String uri = request;
        HttpMethod method = post ? new PostMethod(uri) : new GetMethod(uri);
        configureHttpMethod(method);
        HttpClient client = getHttpClient();
        client.getParams().setParameter(HttpClientParams.SO_TIMEOUT, timeoutLength);
        client.executeMethod(method);
        return method;
    }

My issue is the method.setRequestEntity is saying that the method could not be found.

我的问题是 method.setRequestEntity 说找不到该方法。

I have

我有

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.*;

If i set method = PostMethod instead of method = doREST it works but I don't want to have to do that in all my other methods just to create queries.

如果我设置 method = PostMethod 而不是 method = doREST 它可以工作，但我不想在所有其他方法中这样做只是为了创建查询。

Is there something I am missing as to why the method.setRequestEntity is not working the way it is right now?

关于为什么 method.setRequestEntity 没有按照现在的方式工作，我有什么遗漏吗？

EDIT: I got my information for using setRequestEntity from PostMethod setRequestBody(String) deprecated - why?

编辑：我从PostMethod setRequestBody(String) 中获得了使用 setRequestEntity 的信息- 为什么？

EDIT 2: Here is what I ended up doing.

编辑 2：这是我最终要做的。

private HttpMethod doREST(String request, RequestEntity entity) throws Exception {
        String uri = request;
        HttpMethod method;
        if ( entity != null ){
            method = new PostMethod(uri);
            ((PostMethod) method).setRequestEntity(entity);

        } else {
            method = new GetMethod(uri);
        }
        configureHttpMethod(method);
        HttpClient client = getHttpClient();
        client.getParams().setParameter(HttpClientParams.SO_TIMEOUT, timeoutLength);
        client.executeMethod(method);
        return method;
    }

You should modify doRESTto accept the RequestEntityinstead of a boolean. Pass in nullfor a GET and a value for POST. Use that as the check to see if you need a PostMethodor a GetMethod. Then you can have the specific type so you can call the PostMethodonly setRequestEntity().

您应该修改doREST以接受RequestEntity而不是boolean。传入nullGET 和 POST 值。将其用作检查以查看您是否需要 aPostMethod或GetMethod. 然后您可以拥有特定类型，以便您可以调用PostMethod唯一的setRequestEntity().

EDIT:

编辑：

You can avoid the cast like this:

你可以避免这样的演员阵容：

private HttpMethod doREST(String request, RequestEntity entity) throws Exception {
    String uri = request;
    HttpMethod method;
    if ( entity != null ){
        PostMethod postMethod = new PostMethod(uri);
        postMethod.setRequestEntity(entity);
        method = postMethod;
    } else {
        method = new GetMethod(uri);
    }
    configureHttpMethod(method);
    HttpClient client = getHttpClient();
    client.getParams().setParameter(HttpClientParams.SO_TIMEOUT, timeoutLength);
    client.executeMethod(method);
    return method;
}

The method you should be calling is setEntity, not setRequestEntity. Also, your body should be wrapped in a StringEntity, not a StringRequestEntity, imported from org.apache.http.entity.

您应该调用的方法是setEntity，而不是setRequestEntity。此外，你的身体应该被包裹在一个StringEntity，而不是一个StringRequestEntity，从进口org.apache.http.entity。
