Question

我在java中使用org.json解析json。我的json列表如下：

[ {
"id": "f187b01b145c4171b66d4a2ecabb8f44"
},
{
"id": "a5e66b7462e24924a03e89f0619a2398"
},
{
"id": "2fb3627360db4ab78a0b3f27527b1983"
} ]

我从java代码中获取数据：

Exception in thread "main" org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]
at org.json.JSONTokener.syntaxError(JSONTokener.java:433)
at org.json.JSONObject.<init>(JSONObject.java:197)
at org.json.JSONObject.<init>(JSONObject.java:324)
at br.usp.icmc.teste.ConnectionRestClient.getSaucelabsGetJobs(ConnectionRestClient.java:80)
at br.usp.icmc.teste.TestePrincipal.main(TestePrincipal.java:9)

但它有一个例外：

return $result;

为什么它没有被识别为JSONArray？我哪里错了？

U can try with below code. There are many ways to do it, below is one of the way


JSONArray jsonArray = new JSONArray(response.getEntity(String.class));
        for(int i =0; i< jsonArray.length(); i++){
            if(jsonArray.get(i) instanceof JSONObject){
                JSONObject jsnObj = (JSONObject)jsonArray.get(i);
                String finalValue = (String)jsnObj.get("id");
            }
        }

org.json.JSONException：JSONObject文本必须以“{”为1 [字符2第1行]开头
