android - Foursquare API 请求在使用浏览器与 jsonparsing 时错过了一些价值
问题描述
我正在尝试从 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，我能够获取所有 JSON 信息。但是，当我尝试对我的 Android Studio 上的链接进行 JSON 解析时，我错过了 JSON 对象中的一些值。我包含了来自 Web 浏览器的 JSON 结果，如下所示。如果您看到“items”的 JSONarray 应该具有“reasons”、“snippet”、“venue”、“photo”、“tips”、“referralId”的 JSONobject。但是当我解析它们时，我只能得到“原因”、“地点”和“referralId”。
我尝试使用以下两种方法解析链接：
- 在单独的类中获取 JSON 数据
- 使用 OkHttpClient
- 排球库
与我直接在浏览器上复制/粘贴 URL 链接相比，所有方法都给了我类似的 JSON 结果，这是缺少值（只有“原因”、“地点”和“referralId”）的结果。
这是我尝试使用方法 1（获取数据）的代码。在这种情况下，数据应该在运行 fetchJson().start() 时包含 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2，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);
}
});
}
}
});
}
与我只是将链接直接粘贴到网络浏览器（即谷歌浏览器）相比，我尝试的所有方法都错过了一些价值。
有人可以帮我为什么会这样吗？URL 链接是否受到提供 API 的公司的某种程度的保护？
让我真正好奇的是，浏览器的 JSON 结果比我在 Android Studio 上解析它提供的信息更多。
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，这是 JSON 结果：
