試圖上傳圖像，但得到這個錯誤Android應用程序

Question

即時通訊使用okhttp 2.5.0, 即時通訊照片，然後將其轉換爲基本64格式，然後將其發送到服務器作爲後變量，然後解碼回jpg格式並保存到到服務器.... 當我使用小相似圖片1個百萬像素（0.5MB），它完美... 但是當我將分辨率提高會發生此異常...

我試圖增加文章和上傳大小在php.ini中， 增加了asynctask和okhttp客戶端的時間， 沒有工作

Answer 1

這是拋SocketTimeoutException只是延長超時。

或者在上傳之前添加更多代碼來調整圖片的大小，無論如何您都希望有一個限制。

Answer 2

您正在使用Base64發送圖像。 Base64基本上是一個二進制數據的ASCII表示，它允許我們將數據嵌入到JSON等文本流中，但也應該注意，使用它的數據的大小會增加。您正在接收SocketTimeoutException，因爲數據量很大，上傳呼叫在超時之前未完成，或者網絡速度較慢，並且圖像未在指定時間內上傳。

使用multipart/form-data是在HTTP請求中傳輸二進制文件的標準方式。除非這樣做有一些限制，否則使用這種方法總是更好。

Answer 3

我解決了增加writeTimeout的問題。 在okhttp3嘗試：java.net.SocketException異常：

OkHttpClient.Builder builder = new OkHttpClient(). 
builder.connectTimeout(5, TimeUnit.MINUTES); 
writeTimeout(5, TimeUnit.MINUTES); 
readTimeout(5, TimeUnit.MINUTES); 
okHttpClient = builder.build();
