我们需要从我们的应用中调用第三方API。该调用在大多数情况下都可以正常运行，但有时我们会从第三方服务器收到错误消息，说

POSTMAN发出的相同请求效果很好。我已根据请求和响应为记录器附加了过滤器。下面是记录器的请求响应。

上述请求在我的代码中始终失败，但是同一请求在POSTMAN中效果很好（从记录器复制到邮递员相同的上述请求）。 MyDTO还具有字段和getter / setter。
代码：
public MyDTO create(String path, MyDTO entity) {
Invocation invocation = getTarget()
.path(path)
.request(MediaType.APPLICATION_JSON)
.buildPost(Entity.entity(entity, MediaType.APPLICATION_JSON));
Response response = invocation.invoke();
validateResponse(response, Status.CREATED);
return response.readEntity(new GenericType<MyDTO>() {});
}
private WebTarget getTarget() {
Client client = client = new OpenSSLClientBuilder()
.authentication(username, password)
.proxy(proxy)
.buildClient();
client.register(new EntityLoggingFilter());
return client.target(UriBuilder.fromUri(getProperty(BASEURI)));
}
MYDTO
@JsonInclude(Include.NON_NULL)
public class MyDTO implements Serializable
{
private String id;
private String value;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
@Override
public String toString() {
return "MyDTO{" + "id=" + id + ", value=" + value + '}';
}
}
