我在我的 VPS 中托管的 JSON 文件是 2.2 MB，当我使用 OkHttp 创建一个请求来检索它然后记录 JSON 时，我发现并不是所有的 JSON 都被请求了。
我的代码:
public void sendJSONRequest() {
// init http client
mOkHttpClient = new OkHttpClient();
// init a request
mRequest = new okhttp3.Request.Builder().url(url).build();
// execute the request (async)
mOkHttpClient.newCall(mRequest).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.i(TAG, e.getMessage());
}
@Override
public void onResponse(Call call, okhttp3.Response response) throws IOException {
Log.i(TAG, response.body().string());
parseGameJSONResponse(response.body().string());
}
});
}
parseGameJSONResponse 中抛出的错误:
java.lang.IllegalStateException: closed
at okio.RealBufferedSource.rangeEquals(RealBufferedSource.java:398)
at okio.RealBufferedSource.rangeEquals(RealBufferedSource.java:392)
at okhttp3.internal.Util.bomAwareCharset(Util.java:449)
at okhttp3.ResponseBody.string(ResponseBody.java:174)
抛出错误是因为JSON被截断了
解析json方法:
public ArrayList<Game> parseGameJSONResponse(String json) {
ArrayList<Game> upcomingGames = new ArrayList<>();
// Main JSON Object
JSONObject mainJsonObject = null;
try {
mainJsonObject = new JSONObject(json);
} catch (JSONException e) {
e.printStackTrace();
}
boolean removeDuplicates = mSettingsValue.getRemoveDuplicates();
if (mainJsonObject != null) {
// MAIN JSON Data Array
JSONArray jsonArray = null;
try {
jsonArray = mainJsonObject.getJSONArray("data");
} catch (JSONException e) {
e.printStackTrace();
}
if (jsonArray != null && jsonArray.length() > 0) {
try {
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject gameObject = jsonArray.getJSONObject(i);
Game game = new Game();

谢谢大家。非常感谢任何形式的帮助，非常感谢
最佳答案
它似乎尝试读取相同的 InputStream 两次(可能不会保存在内存中)。
我认为您应该只使用 response.string() 而不是 response.body().string()。
此外，如果您认为这可能与计时有关，您可以编辑超时。
client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();
关于java - OkHttp 没有得到整个 JSON，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48026734/
