Question

我在休息服务调用中返回了JSONArray，如下所示：

frequencies3 <- frequencies2 %>%
  mutate(pvalue = map_dbl(M, ~chisq.test(.x)$p.value)) %>%
  select(-data, -M) %>%
  ungroup()
frequencies3
# # A tibble: 4 x 3
#   contig_ID         ecotype pvalue
#   <fct>             <fct>    <dbl>
# 1 Contig100169_2367 Crab     1.00 
# 2 Contig100169_2367 Wave     0.434
# 3 Contig100169_2481 Crab     0.284
# 4 Contig100169_2481 Wave     0.958

我需要将其转换为

[
 {"REFDATA_KEY":"Rf1","REFDATA_VALUE":"Daily"},
 {"REFDATA_KEY":"Rf2","REFDATA_VALUE":"Weekly"}, 
 {"REFDATA_KEY":"Rf3","REFDATA_VALUE":"Monthly"}
]

如何转换它？

Answer 1

你可以很简单。

map()

或者您可以使用var sd = [{"REFDATA_KEY":"Rf1","REFDATA_VALUE":"Daily"},{"REFDATA_KEY":"Rf2","REFDATA_VALUE":"Weekly"},{"REFDATA_KEY":"Rf3","REFDATA_VALUE":"Monthly"}] var list = sd.map(obj =>{ var returned = {}; returned['Value'] = obj['REFDATA_KEY']; returned['Label'] = obj['REFDATA_VALUE']; return returned; }) console.log(list);函数：

Answer 2

您可以使用org.json库（https://mvnrepository.com/artifact/org.json/json）来实现以下目标：

我们假设您在response JSONArray变量中收到了回复。

JSONArray response = [
 {"REFDATA_KEY":"Rf1","REFDATA_VALUE":"Daily"},
 {"REFDATA_KEY":"Rf2","REFDATA_VALUE":"Weekly"}, 
 {"REFDATA_KEY":"Rf3","REFDATA_VALUE":"Monthly"}
]

您可以编写reformJsonArray()函数，如下所示，response并根据需要返回List<JSONObject>。

public List<JSONObject> test(JSONArray json) {
    List<JSONObject> jsonArrayList = new ArrayList<>();
    for (int index = 0; index < json.length(); index++) {
        JSONObject element = json.getJSONObject(index);

        JSONObject jsonObject = new JSONObject();
        jsonObject.put("value", element.getString("REFDATA_KEY")).put("label", element.getString("REFDATA_VALUE"));

        jsonArrayList.add(jsonObject);
    }
    return jsonArrayList;
}

将JSONArray转换为List
