How to convert HttpEntity into JSON?
提问by user1170330
I want to retrieve JSON from a web-service and parse it then.
Am I on the right way?
我想从网络服务中检索 JSON 并解析它。
我在正确的路上吗？
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
HttpResponse response;
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
// parsing JSON
}
} catch (Exception e) {
}
Unfortunately I don't know how to convert HttpEntityinto a JSONObject.
不幸的是，我不知道如何转换HttpEntity为 JSONObject。
This is my JSON (extract):
这是我的 JSON（摘录）：
{
"names": [
{
"name": "Zachary"
},
{
"name": "Wyatt"
},
{
"name": "William"
}
]
}

You can convert string to json as:
您可以将字符串转换为 json 为：
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
String retSrc = EntityUtils.toString(entity);
// parsing JSON
JSONObject result = new JSONObject(retSrc); //Convert String to JSON Object
JSONArray tokenList = result.getJSONArray("names");
JSONObject oj = tokenList.getJSONObject(0);
String token = oj.getString("name");
}
}
catch (Exception e) {
}

Use the entity.getContent() to get the InputStream and convert it to String.
使用 entity.getContent() 获取 InputStream 并将其转换为 String。

Try this
尝试这个
public String getMyFeed(){
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
HttpResponse response = httpclien.execute(httpget);
HttpEntity entity = response.getEntity();
HttpInputStream content = entity.getContent();
StatusLine sl = response.getStatusLine();
int statCode = sl.getStatusCode()
if (statCode ==200){
// process it
}
}
String readFeed = getMyFeed();
JSONArray jArr = new JSONArray(readFeed);
for(int i=0 ; i<jArr.length ; i++)
JSONObject jObj = jArr.getJSONObject(i);
