如何解决Foursquare API 请求在使用浏览器与 jsonparsing 时遗漏了一些价值
我正在尝试从来自 Foursquare 的 API 请求（HTTP 请求）中获取 JSON 信息。 当我将 HTTP 链接粘贴到浏览器上时，我能够获得所有 JSON 信息。但是当我尝试 JSON 解析 Android Studio 上的链接时，我错过了 JSON 对象的一些值。我包含了来自 Web 浏览器的 JSON 结果，如下所示。如果你看到“items”的JSONarray应该有“reasons”、“snippet”、“venue”、“photo”、“tips”、“referralId”的JSONobject。但是当我解析它们时，我只能得到“原因”、“场地”和“推荐 ID”。
- 在单独的类中获取 JSON 数据
- 使用 OkHttpClient
- 排球图书馆
所有方法都给了我类似的 JSON 结果，与我直接将 URL 链接复制/粘贴到我的浏览器。
这是我尝试使用方法 1（获取数据）的代码。在这种情况下，数据应包含运行 fetchJson().start() 时的 JSON 信息
private class fetchJson extends Thread{
@Override
public void run() {
String url = link; //link contains the HTTPS address
String data = "";
try {
URL url = new URL(link);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null){
data = data + line;
}
Log.d("fetchJson","the url has been turned into the following json: " + data);
} catch (MalformedURLException e) {
Log.e("fetchJson","run: problem with getting the URL is: " + e );
} catch (IOException e) {
Log.e("fetchJson","run: problem with HttpURLConnection is: " + e );
}
}
}
方法二，使用OkHttpClient：
private void JsonParse() {
String url = link;
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(link).build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call,IOException e) {
e.printstacktrace();
}
@Override
public void onResponse(Call call,Response response) throws IOException {
if (response.isSuccessful()){
String myResponse = response.body().string();
FoodActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
Log.d(TAG,"run: the url link should turn into json of: " + myResponse);
}
});
}
}
});
}
与我直接将链接粘贴到网络浏览器（即 Google Chrome）相比，我尝试的所有方法都错过了一些价值。
有人可以帮助我为什么会这样吗？ URL 链接是否受到提供 API 的公司的某种程度的保护？
真正让我感到好奇的是，与在 Android Studio 上解析相比，浏览器的 JSON 结果提供的信息更多。
非常感谢您的时间和帮助。
如果我只是将来自 Foursquare 的 API 请求 HTTP 直接粘贴到 Web 浏览器，则这是 JSON 结果：
