【中文标题】Android 中来自 Django 的 JSON 响应【英文标题】：JSON Response from Django in Android 【发布时间】：2013-03-08 00:42:36 【问题描述】：我正在尝试从基于 Django 的 Web 后端获取 android 中的 JSON 响应。 我得到的回应是

Android 请求
private String GetPickUpDetails(String pick_up_id2)
StringBuilder response = new StringBuilder();
String stringUrl=Constants.PICKUP_DETAILS+pick_up_id2+"/";
URL url;
try
url = new URL(stringUrl);
HttpURLConnection httpconn = (HttpURLConnection)url.openConnection();
if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK)
BufferedReader input = new BufferedReader(new InputStreamReader(httpconn.getInputStream()),8192);
String strLine = null;
while ((strLine = input.readLine()) != null)
response.append(strLine);
input.close();
catch (Exception e)
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("This si the response march API "+response.toString()+" for url"+stringUrl);
return response.toString();
Django 查看代码
def pickup_details(request,id):
awb_dict=
if request.POST:
print "this is post request",id
shipment_records=[]
shippments=Shipment.objects.filter(pickup_id=id)
for obj in shippments:
awb=obj.airwaybill_number
order_number=obj.order_number
pincode=obj.pincode
dest_sc=obj.service_centre
type=obj.product_type
if(type == "ccd"):
col_val=obj.collectable_value
else:
col_val=""
status=obj.status
city=obj.destination_city
act_wt=obj.actual_weight
dest_SC="hi"
dest_SC=obj.service_centre
#dest_SC=String(dest_SC).replace('-',' ')
record="awb":awb,"ordernumber":order_number,"pincode":pincode,"weight":act_wt,"status":status,"city":city,"type":type,"col_value":col_val,"dest_SC":city
shipment_records.append(record)
awb_dict["count"]=len(shipment_records)
awb_dict["shipments"]=shipment_records
#else:
#pass
return HttpResponse(simplejson.dumps(awb_dict) )
我不太确定，为什么我没有得到预期的 JSON 响应。手动点击 url 后，我得到了预期的 JSON 响应
编辑 1 这种方法我也试过了
try
URL url = new URL(stringUrl);
HttpURLConnection httpconn = (HttpURLConnection)url.openConnection();
if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK)
BufferedReader input = new BufferedReader(new InputStreamReader(httpconn.getInputStream()),8192);
String strLine = null;
while ((strLine = input.readLine()) != null)
response.append(strLine);
input.close();
catch (Exception e)
// TODO Auto-generated catch block
e.printStackTrace();
return response.toString();
编辑 2 我得到的错误是 HTTP 403 Request 在尝试发送请求时，因为值没有到达 API 调用
编辑 3
我得到的 HTTP 响应为 200。代码的 HttpEntity entity = response.getEntity(); 的值是 org.apache.http.conn.BasicMangedEntity@4055505d0
【问题讨论】：
您似乎没有发送正确的身份验证信息，并且您返回的错误页面显示了同样多的内容。 也许您需要为请求发送标头："Accept": "application/json"
@Perception , pbespechnyi 请你纠正我吗？
@onkar，我刚用谷歌搜索：icfun.blogspot.com/2009/08/…
奇怪的是您得到的是 403 而不是 401，但无论如何，就像我之前所说的，您调用的服务看起来需要您在检索数据之前进行身份验证。在我们进一步帮助您之前，您需要找出它期望身份验证数据采用什么形式。
【参考方案1】：
响应将我重定向到我使用 @csrf_exempt 的自定义登录页面。代码需要进一步的登录详细信息来处理信息。我在调用的同时添加了登录参数，并获得了所需的响应
【讨论】：
【参考方案2】：TL;DRhttpconn.setRequestProperty("Accept", "application/json");
HttpURLConnection 的默认“Accept”HttpHeader 值为
text/html, image/gif, image/jpeg, *; q=.2, /; q=.2
当使用text/html 时，django 返回用 HTML 包装的 JSON。如果需要纯 JSON，Accept HttpHeader 值应设置为'application/json'

为啥我的来自 Django 的 JSON 在大约 2.1MB 处被截断？
