週末加班調別人給的介面，總是他的介面報錯500。

但是用postman呼叫，設定引數格式為raw的json格式就可以通了，自己的java程式碼就是不通

人家又不加班  自己百度了看看。

查到了好辦法

public static String result;
public static void httpTest() throws ClientProtocolException, IOException {
String token = "R5amyr6NyXCtWdScmNiuvVwBCJztfByZDUGaE2V0NwOUheW4XYlvUusYkrViTYt584RgcyXRhjxAJZG3rFlPLg";
String url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token="
+ token;
String json = "{\"action_name\":\"QR_LIMIT_SCENE\",\"action_info\":{\"scene\":{\"scene_id\":234}}}";
HttpClient httpClient = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
StringEntity postingString = new StringEntity(json);// json傳遞
post.setEntity(postingString);
post.setHeader("Content-type", "application/json");
HttpResponse response = httpClient.execute(post);
String content = EntityUtils.toString(response.getEntity());
// Log.i("test",content);
System.out.println(content);
result = content;
}
