我想从URL的内容创建一个JSONObject对象，所以我从google API获取URL的内容，这就是结果：
"results" : [
{
"address_components" : [
{
"long_name" : "29",
"short_name" : "29",
"types" : [ "street_number" ]
},
{
"long_name" : "Jean",
"short_name" : "Jean",
"types" : [ "route" ]
},
{
"long_name" : "Toulouse",
"short_name" : "Toulouse",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Haute-Garonne",
"short_name" : "31",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "Midi",
"short_name" : "Midi",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "France",
"short_name" : "FR",
"types" : [ "country", "political" ]
},
{
"long_name" : "31000",
"short_name" : "31000",
"types" : [ "postal_code" ]
}
],
"formatted_address" : "99 Jean , 31900 Toulouse, France",
"geometry" : {
"location" : {
"lat" : 43.6069496,
"lng" : 1.4498134
},
"location_type" : "ROOFTOP",
"viewport" : {
"northeast" : {
"lat" : 43.6082985802915,
"lng" : 1.451162380291502
},
"southwest" : {
"lat" : 43.6056006197085,
"lng" : 1.448464419708498
}
}
},
"place_id" : "ChIJTSvW45i8rhIRu8OEgnpnZMY",
"types" : [ "street_address" ]
}
],
"status" : "OK"
}
我想从此内容创建一个JSONObject，就像
JSONObject obj = JSONObject.fromObject(urlConnection.getInputStream());
但检查此对象的大小为0
您需要将InputStream的内容读取为String，您不能直接以这种方式使用它。
阅读类似以下内容的InputStream：
public static String slurp(InputStream is){
BufferedReader br = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line+"\n");
}
br.close();
return sb.toString();
}
然后使用它来获取JSONObject：
JSONObject obj = JSONObject.fromObject(slurp(urlConnection.getInputStream()));
