android - 获取 JSON 响应 Android

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());
}

我无法获得响应。如何在 Logger 或控制台中打印响应。 response.toString() 或 response.getEntity.toString() 不起作用。

我应该将 Content-type 设置为 "application/json" 吗？

一般的做法是:

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

此外，您可以检查响应代码。有时，请求会失败。

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