我正在尝试通过JAVA代码连接到GCM。
application/x-www-form-urlencoded;charset=UTF-8
它工作正常,
但是当我使用Content-Type: application/json
时
我得到JSON_PARSING_ERROR: Unexpected character (r) at position 0
。
我的代码是:
List<NameValuePair> formparams = new ArrayList<NameValuePair>();
formparams.add(new BasicNameValuePair("registration_id",
GCM_ID));
formparams.add(new BasicNameValuePair("data.message",
"this is data mesg"));
// UrlEncodedFormEntity entity = new
UrlEncodedFormEntity(formparams,
// "UTF-8");
HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(REQUEST_URL);
// ADDING DATA IN TO HEADER OF URL
httpPost.setHeader("Authorization",
"key=AIzaSyBmy5WfZMuO-BGMaWEtVhI1f-2gqyN-1h0");
/*httpPost.setHeader("Content-Type",
"application/x-www-form-urlencoded;charset=UTF-
8");*/
httpPost.setHeader("Content-Type",
" application/json"); // not
working
try {
httpPost.setEntity(new
UrlEncodedFormEntity(formparams, "utf-8"));
// RETRIEVING RESPONSE FROM URL
System.out.println("1");
HttpResponse response= httpclient.execute(httpPost);
System.out.println("2");
str =
inputStreamToString(response.getEntity().getContent()).toString();
System.out.println("3");
System.out.println(str+" "+response);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
解析响应的代码是:
private StringBuilder inputStreamToString(InputStream is) {
String line = "";
StringBuilder total = new StringBuilder();
// Wrap a BufferedReader around the InputStream
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
// Read response until the end
try {
while ((line = rd.readLine()) != null) {
total.append(line);
}
} catch (IOException e) {
Log.e("inputStreamToString", "during convert");
e.printStackTrace();
}
// Return full string
return total;
}
答案 0 :(得分:3)
当然它不起作用。您在将内容类型指定为application/x-www-form-urlencoded
时发送application/json
内容。
formparams
不是JSON字符串。
JSON字符串应如下所示:
{
"registration_ids" : ["APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx..."],
"data" : {
"message" : "this is data mesg"
},
}
尝试使用StringEntity
代替UrlEncodedFormEntity
:
这样的事情应该有用,假设jsonString
包含a
字符串格式正确:
httpPost.setEntity(new StringEntity(jsonString, ContentType.APPLICATION_JSON));
