java中的Apache httpclient whith FastBill.api

Question

我是java新手，需要这个项目。我必须结合使用Apache HttpClient和FastBill API。

curl -v -X POST \ 
–u {E-Mail-Adresse}:{API-Key} \ 
-H 'Content-Type: application/json' \ 
-d '{json body}' \ 
https://my.fastbill.com/api/1.0/api.php 

{
    "SERVICE":"customer.create",
    "DATA":
    {
        "CUSTOMER_TYPE":"business",
        "ORGANIZATION":"Musterfirma",
        "LAST_NAME":"Mmann"
    }
}

public class Fastbill implements FastbillInterface  {

private static final String URL_SECURED_BY_BASIC_AUTHENTICATION = "https://my.fastbill.com/api/1.0/api.php";

public Customer createCustomer(String firstname, String lastname, CustomerType customertype, String organisation) {

    CredentialsProvider provider = new BasicCredentialsProvider();
    UsernamePasswordCredentials credentials
     = new UsernamePasswordCredentials("*****@****", "************"); //Api Username and API-Key


    HttpClient client = HttpClientBuilder.create()
      .setDefaultCredentialsProvider(provider)
      .build();


    HttpPost httpPost = new HttpPost(URL_SECURED_BY_BASIC_AUTHENTICATION);
    httpPost.setHeader("Content-Type", "application/json");
    String json = "{\"SERVICE\":\"customer.create\",\"DATA\":{\"CUSTOMER_TYPE\":\"business\",\"ORGANIZATION\":\"Musterfirma\",\"LAST_NAME\":\"Newmann\"}}";
    try {
        HttpEntity entity = new ByteArrayEntity(json.getBytes("UTF-8"));
        httpPost.setEntity(entity);
    } catch (UnsupportedEncodingException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    HttpResponse response;
    try {           
        response = client.execute(httpPost);
        int statusCode = response.getStatusLine()
                  .getStatusCode();
        System.out.println(statusCode);
        String responseString = new BasicResponseHandler().handleResponse(response);
        System.out.println(responseString);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }catch (Exception e){
        e.printStackTrace();
    }

org.apache.http.client.HttpResponseException: Unauthorized
at org.apache.http.impl.client.AbstractResponseHandler.handleResponse(AbstractResponseHandler.java:70)
at org.apache.http.impl.client.BasicResponseHandler.handleResponse(BasicResponseHandler.java:66)
at fastbillAPI.Fastbill.createCustomer(Fastbill.java:93)
at main.Mar.main(Mar.java:38)

现在，我不知道我做错了什么。

我也遇到过类似的问题，通过使用Matt S.Apache HTTP BasicScheme的示例解决方案解决了这些问题。Authenticate deprecated？。

通过以下方式进行身份验证：

UsernamePasswordCredentials creds = new UsernamePasswordCredentials("admin", "admin");
URI uriLogin = URI.create("http://localhost:8161/hawtio/auth/login/");
HttpPost hpPost = new HttpPost(uriLogin);
Header header = new BasicScheme(StandardCharsets.UTF_8).authenticate(creds , hpPost, null);
hpPost.addHeader( header);
