我正在實施一項服務，用於將文件上傳到雲服務。 我使用OkHttp將大文件分塊加載。 邏輯是這樣的，我從服務器獲取加載url和頭文件，然後將塊加載到雲中，依此類推。 問題，經過約〜200塊我得到這個錯誤：打開文件過多錯誤android

這裏是處理上傳代碼：
try {
HashMap<String, String> headers = response.getHeaders();
String url = response.getUrl();
if (source==null)
source = Okio.buffer(Okio.source(file));
if (content==null)
content = new ChunkFileRequestBody(source, size, contentType);
Request.Builder builder = new Request.Builder();
for (Map.Entry<String, String>entry : headers.entrySet()) {
builder.addHeader(entry.getKey(), entry.getValue());
}
Request azureRequest = builder.url(url).put(content).build();
Response azureResponse = client.newCall(azureRequest).execute();
if (azureResponse.code()/100==2 && shouldContinue) {
Log.e(getClass().getSimpleName(), azureResponse.code() + " " + azureResponse.message());
uploadedBodyBytes +=size;
if (uploadedBodyBytes>=totalBodyBytes) {
cleanUp();
confirmUpload();
}
else {
broadcastProgress(uploadedBodyBytes, totalBodyBytes);
upload();
}
這是自定義的內容主體：
public class ChunkFileRequestBody extends RequestBody {
private final String contentType;
private long uploadSize;
private BufferedSource source;
public ChunkFileRequestBody(BufferedSource source, Long size, String contentType) {
this.source = source;
this.contentType = contentType;
this.uploadSize=size;
}
@Override
public long contentLength() {
return uploadSize;
}
@Override
public MediaType contentType() {
return MediaType.parse(contentType);
}
@Override
public void writeTo(BufferedSink sink) throws IOException {
source.readFully(sink.buffer(), uploadSize);
sink.flush();
}
}
這不能是文件處理中的泄漏，因爲我只打開一次文件。內存使用似乎也很好。 看來好像OkHttp無法正確關閉套接字。我問了圖書館的作者，但他們無法幫助解決這個問題。
有人有過這樣的事嗎？請幫忙
