Android - 获取请求收到EOFException

Question

代码：

    String recipeName = this.recipe.getName().replace(" ", "%20");;
    String recipeIngredients = this.recipe.getIngredients().replace(" ", "%20");;
    String recipeInstructions = this.recipe.getInstructions().replace(" ", "%20");;
    String recipeUserName = this.recipe.getUserName().replace(" ", "%20");;
    int recipeRate = this.recipe.getRate();
    int recipeAmountOfRate = this.recipe.getAmountOfRates();
    String link = "http://***My_Site***/createRecipe.php?recipeName="+recipeName+"&recipeIngredients="+recipeIngredients
            +"&recipeInstructions="+recipeInstructions+"&recipeUserName="+recipeUserName+"&recipeRate="+recipeRate+
            "&recipeAmountOfRate="+recipeAmountOfRate;
    URL url = new URL(link);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
    urlConnection.setChunkedStreamingMode(0);
    try {
        InputStream in = new BufferedInputStream(urlConnection.getInputStream());
        int ch;
        StringBuffer sb = new StringBuffer();
        while ((ch = in.read()) != -1) {
            sb.append((char) ch);
        }
        Log.e("Error", sb.toString());
    } catch(Exception e) {
        Log.e("Error", e.toString());
    } finally {
        urlConnection.disconnect();
    }
}

但我得到错误：

  

E /错误：java.io.EOFException

为什么？ 在先前的请求中，请求变得很好。 请求URL请求的时间太长了？
