问题
I am trying to post a xml from an html text area based from the curl command below
curl -X POST --data-urlencode 'xml=<hml>...</hml>' http://miring.b12x.org/validator/ValidateMiring/
Here is my code so far
@Produces("application/xml")
public String validate(@FormParam("xml") String xml) {
try {
Client client = Client.create();
WebResource webResource = client.resource("http://miring.b12x.org/validator/ValidateMiring/");
// POST method
//Posting null for some reason.
ClientResponse response = webResource.accept("application/xml").post(ClientResponse.class, xml);
// check response status code
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
}
// display response
String output = response.getEntity(String.class);
System.out.println("Output from Server .... ");
System.out.println(output + "\n");
return output;
} catch (Exception e) {
e.printStackTrace();
}
return "Oops";
}
When I run this with an XML that has been tested to work to the webapp I keep getting the null entry response.
I am not sure where to proceed
EDIT: Primary question has been answered below. Bug appears with a + in the xml below is an example. Under the "consensus-sequence block is the "+" with strand. all other enumerations work (-,-1,1)

回答1:
From the Javadoc of @FormParam (emphasis mine):
Binds the value(s) of a form parameter contained within a request entity body to a resource method parameter.
That is, if you invoke your validate() method e.g. from cURL like this
curl -X POST --data-urlencode 'xml=<hml>...</hml>' http://localhost:8080/validate
then the method parameter xml will be bound to the value <hml>...</hml> on which the ValidateMiring service returns a message XML is null. (at least to me).
If you, instead, prepend your method parameter with a prefix xml= before you post it to the actual web service, you should get a different result:
ClientResponse response = webResource.accept("application/xml").post(ClientResponse.class, "xml=" + xml);
