我作为HTTP-Response获得的JSON-String / Array在一行中,如下所示:
[{
"haendlerName": "Zielpunkt",
"shops": [{
"shopId": 243779,
"ort": "Wien",
"strasse": "Erdbergstraße 61",
"plz": "1030",
"lat": 48.19867,
"lon": 16.400263,
"distance": 0.14937061106081023,
"openinghours": null
}],
"imageLink": "http://images.schnapp.at/images/zielpunkt__e349e2a937b5bf4f78e0fb3063b1fca8.png",
"account_id": 171619
}, ...
我正在加载它:
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
response = httpclient.execute(httpGet);
HttpEntity resEntity = response.getEntity();
String response2=EntityUtils.toString(resEntity);
JSONArray finalResult = new JSONArray(response2);
编辑:工作版!
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
response = httpclient.execute(httpGet);
String json = EntityUtils.toString(response.getEntity());
finalResult = new JSONArray(json);
但是在最后一行它崩溃了,只有我得到的错误是NullPointerException。 我检查了tokener的内容,似乎很好。 还检查了整个输入(来自http响应的String),它是一个有效的JSON字符串。
值得一提的是,主数组中的JSONObjects还包含一个子数组。
任何想法可能导致崩溃的原因?或者我做错了什么?
答案 0 :(得分:1)
删除BufferedReader
,String json
和JSONTokener tokener
。试试这种方式
String json = EntityUtils.toString(response.getEntity());
JSONArray finalResult = new JSONArray(json);
EntityUtils.toString
读取Entity
的内容并将其作为String
你应该替换:
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
JSONTokener tokener = new JSONTokener(json);
JSONArray finalResult = new JSONArray(tokener);
带
String json = EntityUtils.toString(response.getEntity());
JSONArray finalResult = new JSONArray(json);
