我在使用 WSO2is-5.2.0 SCIM 接口时遇到了一些奇怪的问题。
这是一个移动应用项目，我们决定使用 WSO2 IS 作为身份管理。客户注册是通过 WSO2 IS 的 SCIM 接口完成的。
在移动设备上通过带有 content-type = application/json 的 Restful post 消息输入并提交用户名和密码（参见下面的 TS 代码）
public signin(){
let data = {"userName":this.sf.get("userName").value,
"password":this.sf.get("password").value};
debugger;
this.gabriel.create(data).subscribe(
(res) => {
this. _res = res;
debugger;
},
error => {
console.log('somthing went wrong ');
},
() => {}
);
}
网关是 apache cxf JAX-RS；我们使用 wso2 Charon 代码集来确保与 WSO2 IS 的兼容性。
在门口，这个请求被拦截并解释为“org.wso2.charon.core.objects.User”的子类（见下面的代码）
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@Path("/signin")
public ScimRes signin(GubUser signin);
GubUser 和ScimRes 的定义
public class GubUser extends User {
private static final long serialVersionUID = 5431026567781364473L;
public GubUser() {
super();
}
...
public class ScimRes {
private int state;
private String id;
public int getState(){
return this.state;
}
public void setState(int state){
this.state = state;
}
...
扩展 User 类的原因是我们想要包含来自终端的一些额外信息。并且这些额外信息在传递到 WSO2 IS SCIM 接口之前从对象中删除，以便发送到 WSO2 IS SCIM 接口的数据 100% 符合用户定义（参见下面的代码）
@Override
public ScimRes signin(GubUser signin) {
if(signin == null){
return null;
}
Boolean klp = null;
String device = null;
String user = null;
try {
klp = signin.getKlp();
if(klp != null && klp.booleanValue() == true){
device = signin.getGubDevice();
signin.deleteAttribute("klp");
signin.deleteAttribute("gubDevice");
}
Observable.just(signin)
.flatMap(in -> {return Observable.just(Scim.createUser(in));})
.subscribe(res -> this.scimRes = res);
...
现在，调用 WSO2 IS SCIM（见下面的代码）
public class Scim {
private static HttpClient client = new DefaultHttpClient();
private static String basicAuthToken = setBasicAuthToken();
public static ScimRes createUser(User user) throws CharonException, ClientProtocolException, IOException, ParseException{
String encodedUser = new SCIMClient().encodeSCIMObject(user, SCIMConstants.JSON);
HttpPost post = new HttpPost(Params.scimUrl);
post.addHeader(SCIMConstants.AUTHORIZATION_HEADER, basicAuthToken);
post.addHeader("Accept", SCIMConstants.APPLICATION_JSON);
post.addHeader("Accept-Charset", "utf-8");
StringEntity entity = new StringEntity(encodedUser, SCIMConstants.APPLICATION_JSON, "UTF-8");
post.setEntity(entity );
ScimRes scimRes = new ScimRes();
HttpResponse res = client.execute(post);
scimRes.setState(res.getStatusLine().getStatusCode());
int resStatus = scimRes.getState();
if(resStatus == HttpStatus.SC_CREATED || resStatus == HttpStatus.SC_OK ){
InputStream is = res.getEntity().getContent();
JSONParser jsonParser = new JSONParser();
JSONObject jo = (JSONObject)jsonParser.parse(new InputStreamReader(is, "UTF-8"));
scimRes.setId((String)jo.get("id"));
is.close();
}
return scimRes;
}
程序被困在
JSONObject jo = (JSONObject)jsonParser.parse(new InputStreamReader(is, "UTF-8"));
我得到了 http 响应消息头的副本（见下文）
HTTP/1.1 200 OK [X-Frame-Options: DENY, X-Content-Type-Options: nosniff, X-XSS-Protection: 1; mode=block, Content-Type: text/html;charset=UTF-8, Content-Length: 1445, Date: Tue, 06 Dec 2016 11:52:39 GMT, Server: WSO2 Carbon Server]
以及堆栈打印输出
Unexpected character (<) at position 0.

似乎消息正文以“<”开头。在 JSON 解析期间触发了异常。
有人有什么想法吗？或任何意见？或建议？
谢谢
