Question

我使用Entrez Utilities Web Service library从我的Java应用程序访问pubmed文章（使用pubmed标识符）。完整工作示例如何使用此工具由Renaud在此post github上发布。在大多数情况下，一切都运行良好，但最近我发现了一个发布的id，这会导致库崩溃。

我使用的代码如下所示：

public PubmedArticleType searchById(Integer id) throws RemoteException {
    EUtilsServiceStub.ESearchRequest req = new EUtilsServiceStub.ESearchRequest();
    req.setDb("pubmed");
    req.setTerm(id+"[uid]");
    req.setEmail("gmail@gmail.com");
    req.setUsehistory("y");
    EUtilsServiceStub.ESearchResult res = service.run_eSearch(req);
    String webEnv = res.getWebEnv();
    String query_key = res.getQueryKey();

    EFetchPubmedServiceStub.EFetchRequest req2 = new EFetchPubmedServiceStub.EFetchRequest();
    req2.setWebEnv(webEnv);
    req2.setQuery_key(query_key);

    EFetchPubmedServiceStub.EFetchResult res2 = service2.run_eFetch(req2);
    for (int j = 0; j < res2.getPubmedArticleSet().getPubmedArticleSetChoice().length; j++) {

        PubmedArticleType art = res2.getPubmedArticleSet().getPubmedArticleSetChoice()[j].getPubmedArticle();
        if (art != null) {
            return art;
        }
    }
    return null;
}

当我用id = 22363258调用此函数时，我得到的错误根本没有提供信息：

所以，我有两个问题：

是什么原因？我能做些什么来解决它？
我是否可以使用其他任何Java API来访问pubmed摘要？我知道我可以解析HTML页面，但我真的不想这样做，因为它引入的问题比解决的问题还多......

Answer 1

Here是一个RESTful API，允许从pubmed db中检索摘要和所有元信息。

将检索我需要的所有数据的确切链接如下所示：http://www.ebi.ac.uk/europepmc/webservices/rest/search/resulttype=core&query=ext_id:22363258
