Question

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL);

try {
    StringEntity documentStringified = new StringEntity(Obj.toString());
    httpPost.setEntity(documentStringified);
} catch (UnsupportedEncodingException e) {
    Log.d("UnsupportedEncodingException", e.toString());
}

try {
    HttpResponse response = httpClient.execute(httpPost);
    Log.d("Response", response.toString());
} catch (IOException e) {
    Log.d("IOException", e.toString());
}

我无法获得response。如何在Logger or console. response.toString()或response.getEntity.toString()中打印回复不起作用。

我应该将内容类型设置为"application/json"。

Answer 1

一般方法是：

String result = EntityUtils.toString(response.getEntity());

此外，您可以查看响应代码。有时，请求失败。

int status = response.getStatusLine().getStatusCode();
if (status == 200) {
    String result = EntityUtils.toString(response.getEntity());    
}

Answer 2

从响应中获取InputStream，然后使用Scanner来使用其内容。

String responseContent = new Scanner(inputStream).useDelimiter("\\A").next();

useDelimiter("\\A")表示＆＃34;分隔符是流的结尾＆＃34;，因此next()会占用所有内容。
