我正在使用letters_list = [0,1,2,3,10,11]
def check_letter(ProductCode):
global letters_list
for l in letters_list:
if not ProductCode[l].isalpha: return False
return True
if check_letter(ProductCode): print("Everything in list is a letter") #define ProductCode
else: print("Something is wrong")
发送包含json原始数据的HTTP POST请求：
DefaultHttpClient我正在使用它发送5个请求，结果必须是json-raw-response，尽管我得到的是前两个响应，但其他三个我得到的是一个HTML代码网页：
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppostreq = new HttpPost(post_url);
StringEntity se = new StringEntity(json.toString()); // json is my JSONObject
se.setContentType("application/json;charset=UTF-8");
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
httppostreq.setEntity(se);
HttpResponse httpresponse = httpclient.execute(httppostreq);
String responseText = EntityUtils.toString(httpresponse.getEntity());
那么，是什么能让我得出这个结果以及我的工作中可能出现的问题呢？
