HTTPS経由でサーバーにPOSTリクエストを送信しようとすると、NullPointerExceptionが発生します。これは自己署名証明書ではありません(CheapSSLsによって発行されます)。

これは私が受け取っているエラーです:

私のコードは次のとおりです。

URL url = new URL(mUrl);
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("192.168.1.134", 8888));
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection(proxy);

urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);

MultipartBodyBuilder builder = new MultipartBodyBuilder();
builder.build(params);

urlConnection.setRequestProperty("Content-Type",  "multipart/form-data; boundary=" + builder.mBoundary);
urlConnection.setFixedLengthStreamingMode(builder.getContentLength());

DataOutputStream out = new DataOutputStream(new BufferedOutputStream(urlConnection.getOutputStream()));

getOutputStreamでコードがクラッシュします。

どんな助けでも大歓迎です。

proxyミックスにオブジェクトを含めずに試してみてください...HttpsConnection仕事を成し遂げるのに十分なはずです。
