json java =＆gt中的逃生角色; JavaScript

Question

问题是无效的JSON结构，并增加了逃生后斜线。

在我（JS）前端读取JSON的错误时，我从Jax-Rs Java球衣后端获取了错误。

4. JSON结果： [JS]原始fetch（post）=＆gt; console.log（）

Object { zoekopdracht: "{\"metadata\":{\"pagination\":{\"total\":2,\"pages\":1,\"rows\":1000,\"currentPage\":1}},\"person\":[{\"geo\":null,\"entity_uuid\":\"e0d8fc91-3e07-313a-e5d1-b35da2ea4f5d\",\"metadata\":{\"datum\":\"1956-00-00\",\"deed_type_title\":\"Registratie\",\"register_gemeente\":\"Amsterdam\",\"has_assets\":\"register\",\"person_display_name\":\"Harry Potter\",\"plaats\":\"Amsterdam\",\"ordering\":0,\"geslachtsnaam\":\"Potter\",\"register_type_title\":\"Archiefkaarten\",\"achternaam\":\"Potter\",\"modified_time\":\"2020-08-10T03:38:16.73421\",\"voornaam\":\"Harry\",\"type_title\":\"Geregistreerde\",\"filter_rol\":\"Geregistreerde\",\"datum_geboorte\":\"1956-00-00\",\"register_naam\":\"Archiefkaarten\"},\"location_name\":null,\"entity_type\":\"ams_person\",\"location\":null,\"id\":\"9853340f-d52e-56a3-e053-b784100ade19\",\"deed_id\":\"9853340f-d52d-56a3-e053-b784100ade19\",\"title\":\"\",\"register_id\":\"08ebb210-5812-b104-bbb6-24b8326b3ea3\",\"timestamp\":\"2021-11-07T16:56:19.552Z\"},{\"geo\":null,\"entity_uuid\":\"e0d8fc91-3e07-313a-e5d1-b35da2ea4f5d\",\"metadata\":{\"datum\":\"1933-00-00\",\"deed_type_title\":\"Registratie\",\"register_gemeente\":\"Amsterdam\",\"has_assets\":\"register\",\"person_display_name\":\"Harry Johan Potter\",\"plaats\":\"Amsterdam\",\"ordering\":0,\"geslachtsnaam\":\"Potter\",\"register_type_title\":\"Archiefkaarten\",\"achternaam\":\"Potter\",\"modified_time\":\"2020-08-15T10:51:18.555689\",\"voornaam\":\"Harry Johan\",\"type_title\":\"Geregistreerde\",\"filter_rol\":\"Geregistreerde\",\"datum_geboorte\":\"1933-00-00\",\"register_naam\":\"Archiefkaarten\"},\"location_name\":null,\"entity_type\":\"ams_person\",\"location\":null,\"id\":\"98533417-bc90-56a3-e053-b784100ade19\",\"deed_id\":\"98533417-bc8f-56a3-e053-b784100ade19\",\"title\":\"\",\"register_id\":\"08ebb210-5812-b104-bbb6-24b8326b3ea3\",\"timestamp\":\"2021-11-07T07:09:54.402Z\"}],\"links\":{\"person.detail\":\"https://webservices.picturae.pro/genealogy/person/{person.id}\"}}" }

确定，这是管道，

1. [js] fetch（post）=＆gt;拥有后端休息服务（Java），

2. [Java]然后进行后端fetch =＆gt;外部API（无控制），

3. [java]然后将其返回原始fetch（post），

4. [js]原始fetch（post）=＆gt; console.log（）

沿线某个地方添加了各种后斜切，我已经通过阅读它来删除了许多。

1. [js] fetch（post）=＆gt;拥有后端休息服务（Java），

  const fetchOptions = {
    method: 'POST',
    body: JSON.stringify(jsonRequestBody),
    headers: {
      Authorization: `Bearer ${window.sessionStorage.getItem('JWT')}`,
      Accept: 'application/json',
      'Content-Type': 'application/json',
    },
  };
  const feedbackSpan = document.getElementById('feedbackSpan');

  fetch(`${localhost}restservices/search-advanced-service/`, fetchOptions)
    .then(async (response) => {
      if (response.status === 200) {
        // er is een account gevonden !
        const myJson = await response.json(); // return the search results incl changelog
        console.log(myJson);

        const myJsonString = JSON.stringify(myJson, null, 2);

        console.log(myJsonString.replace('\\',''));
        console.log(JSON.parse(myJson));
        console.log(JSON.stringify(myJsonString));
      }
      if (response.status === 403) {
        feedbackSpan.innerHTML = '<p>Check of je bent ingelogd!</p>';
      }
    })
    .catch((err) => {
      console.log('Error: ', err);
    });
}

2. [Java]然后进行后端fetch =＆gt;外部API（无控制），

    public JSONObject fetchSearchResultAsJson(String theURL) throws IOException {
        URL url = new URL(theURL);
        InputStream is = url.openStream();
        int cursor = 0;
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is));
        JSONTokener tokener = new JSONTokener(bufferedReader);
        JSONObject json = new JSONObject(tokener);

        is.close();
        bufferedReader.close();
        return json;
    }
}

3. [Java]然后将其返回到原始fetch（post），

    @POST
    @RolesAllowed("user")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    @Path("")
    public Response advancedSearchProcess(SearchAdvancedInput searchQuery, @Context SecurityContext sc) {
        System.out.println("advancedSearchProcess");
        try {
                for (String zoekUri : zoekopdracht.getZoekUris()) {
                    JSONObject resultaat = fetchSearchResultAsJson(zoekUri);
                    messages.put("zoekopdracht",
                            resultaat.toString()
                    );
                }
                return Response.ok().entity(messages).build();

            
        } catch (Exception exception) {
            return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(exception).build();
        }
    }
