我需要使用
java POJO类映射
JSON数组对象.
我写了这样的代码：
我写了这样的代码：
// execute the client with get method
InputStream inputStream = getMethod.getResponseBodyAsStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
ObjectMapper objectMapper = new ObjectMapper();
JsonFactory jsonFactory = new JsonFactory();
List<OwnerDetail> owners = new ArrayList<>();
JsonParser jsonParser = jsonFactory.createJsonParser(inputStream);
if (jsonParser.nextToken() != null && jsonParser.)
{ // end-of-input
owners = objectMapper.readValue(bufferedReader,TypeFactory.defaultInstance().constructCollectionType(List.class,OwnerDetail.class));
}
以上块给出了以下错误：
com.fasterxml.jackson.databind.JsonMappingException: No content to map due to end-of-input at [Source: java.io.BufferedReader@5e66c5fc; line: 1,column: 1] at com.fasterxml.jackson.databind.JsonMappingException.from(JsonMappingException.java:164) at com.fasterxml.jackson.databind.ObjectMapper._initForReading(ObjectMapper.java:3029) at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:2971) at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:2128)
任何帮助,将不胜感激.谢谢.
解决方法
读取响应后,将消耗响应中的数据.
如果您的代码是拦截器,您可以尝试再次创建响应并返回如下：
如果您的代码是拦截器,您可以尝试再次创建响应并返回如下：
Request request = chain.request();
Response originalResponse = chain.proceed(request);
final ResponseBody original = originalResponse.body();
// if(request.url().toString().equalsIgnoreCase(string)){
if (originalResponse.code() == HttpURLConnection.HTTP_OK) {
try {
String response = originalResponse.body().string();
JSONObject mainObject = new JSONObject(response);
// your mapping - manipulation code here.
originalResponse = originalResponse.newBuilder()
.header("Cache-Control","max-age=60")
.body(ResponseBody.create(original.contentType(),mainObject.toString().getBytes()))
.build();
} catch (JSONException | IOException e) {
e.printStackTrace();
}
}
return originalResponse;
这里再次创建响应并返回.
请告诉我任何更新.
