Question

我正在使用DuckDuckGo Api，它在解析json时有时会给我错误，我无法找到原因。这是我使用的代码：

private String getUrls(String urlapi) throws IOException, JSONException {
            InputStream in = null;
            in = connectTo(urlapi);
            String result = requestResponseAsString(in);
            String fullResult = parseJSON(result);
            return fullResult;

        }

        private String parseJSON(String result) throws JSONException {
            String url = null;
            JSONObject jObject = new JSONObject(result);
            JSONArray arr = jObject.getJSONArray("Results");
            if(arr.length()>0){
                url = arr.getJSONObject(0).getString("FirstURL");
                System.out.println(url);}
            return url;
        }

来自A JSONObject text must begin with '{' error，

JSON对象遵循以下结构：

url=$(printf '%s/%s/res/%s?where={%%22timestamp%%22:{%%22$gt%%22:{%%22$date%%22:%%22%s%%22},%%22$lt%%22:{%%22$date%%22:%%22%s%%22}}}&paging=limit:100,page:%s' "$env" "$name" "$type" "$date1" "$date2" "$i")

resp=$(curl -g -u "$usr:$pwd" -X GET "$url")

JSON数组遵循以下结构：

{
 "array": [
{
    color: "red",
    value: "#f00"
},
{
    color: "green",
    value: "#0f0"
}
]
}

JSONObject文本必须以＆＃39; {＆＃39;在java中的1 [字符2第1行]
