我正在尝试休息使用泽西客户端接听电话。基于api文档,请求将图像作为二进制数据返回。当我完成其余的使用邮递员接听电话时,我可以将实际图像恢复(我asumming postman将二进制文件转换回图像/ png)。这是邮递员返回的以下标题。
我尝试完成其余的在java中使用jersey客户端。这是我的代码:
private Client client = ClientBuilder.newClient( new ClientConfig().register(LoggingFilter.class).register(MultiPartFeature.class));
private WebTarget myServer;
myServer= client.target(baseURL);
public void restGetImage(String requestURL, String headers) {
BufferedReader br = null;
StringBuilder sb = new StringBuilder();
String line;
MultivaluedMap<String, Object> userHeaders = storeHeadersInMap(headers);
WebTarget target = getWebTarget().path(requestURL);
Response response = target.request(MediaType.APPLICATION_OCTET_STREAM)
.headers(userHeaders)
.get();
System.out.println("Reuqest URL: " + session.get("baseurl") + requestURL);
int responseCode = response.getStatus();
InputStream inputStream = response.readEntity(InputStream.class);
String contentType = response.getHeaderString("Content-Type");
// br = new BufferedReader(new InputStreamReader(inputStream));
//
// try {
// while((line = br.readLine()) != null) {
// sb.append(line);
// }
//
// br.close(); //close buffered reader
//
// } catch (IOException e) {
// e.printStackTrace();
//
// }
//
// RestResponse data = new RestResponse(responseCode, sb.toString(), contentType);
// data.setResponseHeader(response.getHeaders());
//
// System.out.println("response code: " + responseCode);
// System.out.println("response Content-Type: " + contentType);
// System.out.println("Response body: " + sb.toString());
// return data;
}
请原谅所有评论,因为我仍在测试代码。基本上代码返回200响应状态,但是当它无法读取响应时。它在InputStream inputStream = response.readEntity(InputStrean.class)中抛出异常。

我的目标是能够读取二进制响应数据。任何洞察力都会被提升。感谢。
答案 0 :(得分:3)
SEVERE:找不到媒体类型= image / png,类型=类
的MessageBodyReader com.itextpdf.text.pdf.codec.Base64 $ InputStream,genericType = class
com.itextpdf.text.pdf.codec.Base64 $的InputStream。
您正在使用错误的{- Define an employee type -}
data Employee = Engineer {name :: String, engineerId :: String}
| Manager {name :: String, managerId :: Integer}
| Director {name :: String, directorId :: Integer}
deriving Show
课程。您应该使用java.io.InputStream
。检查并修复您的导入。
