JAX-RS @PathParam How to pass a String with slashes, hyphens & equals too
提问by Sashi Kiran Challa
I am new to JAX-RS and I am trying to use Jersey to build a simple RESTful Webservice.
我是 JAX-RS 的新手，我正在尝试使用 Jersey 来构建一个简单的 RESTful Web 服务。
I have 2 questions. Please clarify these:
我有2个问题。请澄清这些：
I am trying to have my simple webservice like this URL
http://localhost:8080/SampleJersey/rest/inchi/InChINameThe InChIName is a string like this
InChI=1S/C9H8O4/c1-6(10)13-8-5-3-2-4-7(8)9(11)12/h2- 5H,1H3,(H,11,12). How do I pass this as a@PathParam, I mean a normal String is working fine but here there are slashes,hyphens, and commas. How do I make it to ignore these. I tried putting it in quotes, but that didnt work. How should I do this?I need to pass that
InChIto another webservice and that returns an XML as an output and I want to display that XML output as my Webservice's output. If I have@Produces("application/xml")will it work?
我试图让我的简单网络服务像这个 URL
http://localhost:8080/SampleJersey/rest/inchi/InChINameInChIName 是这样的字符串
InChI=1S/C9H8O4/c1-6(10)13-8-5-3-2-4-7(8)9(11)12/h2- 5H,1H3,(H,11,12)。我如何将它作为 a 传递@PathParam，我的意思是一个普通的 String 工作正常，但这里有斜杠、连字符和逗号。我如何让它忽略这些。我试着把它放在引号中，但这没有用。我该怎么做？我需要将它传递
InChI给另一个 Web 服务并返回一个 XML 作为输出，我想将该 XML 输出显示为我的 Web 服务的输出。如果我有@Produces("application/xml")它会起作用吗？
This is my code:
这是我的代码：
@Path("/inchi")
public class InChIto3D {
@GET
@Path("{inchiname}")
@Produces("application/xml")
public String get3DCoordinates(@PathParam("inchiname")String inchiName) {
String ne="";
try{
URL eutilsurl = new URL(
"http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?"
+ "db=pccompound&term=%22"+inchiName+"%22[inchi]");
BufferedReader in = new BufferedReader(
new InputStreamReader(eutilsurl.openStream()));
String inputline;
while ((inputline=in.readLine())!=null)
ne=ne+inputline;
}catch (MalformedURLException e1) {
}catch (IOException e2){
}
return ne;
}
}

The parameters should be URL encoded. You can use java.net.URLEncoderfor this.
参数应该是URL 编码的。您可以java.net.URLEncoder为此使用。
String encodedParam = URLEncoder.encode(unencodedParam, "UTF-8");
The /will then be translated to %2F.
然后/将被翻译成%2F.

I got this to work using @QueryParam() rather than @PathParam.
我使用@QueryParam() 而不是@PathParam 让它工作。
@Path("/inchi")
public class InChIto3D {
@GET
//@Path("{inchiname}")
@Produces("application/xml")
public String get3DCoordinates(@QueryParam("inchiname") String inchiName) {
String ne="";
try{
URL eutilsurl = new URL(
"http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?"
+ "db=pccompound&term=%22"+inchiName+"%22[inchi]");
BufferedReader in = new BufferedReader(
new InputStreamReader(eutilsurl.openStream()));
String inputline;
while ((inputline=in.readLine())!=null)
ne=ne+inputline;
}catch (MalformedURLException e1) {
}catch (IOException e2){
}
return ne;
}
}
Thus the URL structure would be like this http://myrestservice.com/rest/inchi?inchiname=InChIhere
因此 URL 结构将是这样的http://myrestservice.com/rest/inchi?inchiname=InChIhere
With @PathParam I read in the API that it will not accept slashes. I am wondering if I can use any Regular Expression in @Path just to ignore all slashes in the string that would be entered in quotes" ".
使用@PathParam，我在 API 中读到它不接受斜杠。我想知道是否可以在@Path 中使用任何正则表达式来忽略字符串中将在引号中输入的所有斜杠“”。

Tomcat does not Accept %2F in URLs: http://tomcat.apache.org/security-6.html. You can turn off this behavior.
Tomcat 不接受 URL 中的 %2F：http: //tomcat.apache.org/security-6.html。您可以关闭此行为。

This is how you enable slashes in path params:
这是在路径参数中启用斜杠的方法：
@Path("{inchiname : .+}")
public String get3DCoordinates(@PathParam("inchiname")String inchiName)
回答by AmanicA
The following should work:
以下应该工作：
@GET
@Path("{inchiname : (.+)?}")
@Produces("application/xml")
public String get3DCoordinates(@PathParam("inchiname")String inchiName) {
(This is sort of mentioned in another answer and comment, I'm just explicitly putting it in a separate answer to make it clear)
（这是在另一个答案和评论中提到的，我只是明确地将它放在一个单独的答案中以使其清楚）
