获取 JSON 异常没有价值?
Getting JSON Exception no value for?
我正在尝试处理 json 响应,就像
{"Status":true,"UserId":111,"FirstName":"dev","LastName":"dev","Gender":-1,"BirthdayDate":"0000-00-00","Phone":"","ProfilePicture":"","ProfilePicture60px":"","ProfilePicture120px":"","CountryId":-1,"Email":"droidwithmxxmail.com","Password":"******123","RegisterDate":"2015-05-08 20:08:07","SessionId":"fce248fe6499b7a9338a1b64554509eb77841"}
但得到 org.json.JSONException: no value for exception
我的代码是这样的。
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
allres =jsonObj.getJSONArray(jsonStr);
for (int i = 0; i < allres.length(); i++) {
JSONObject c = allres.getJSONObject(i);
userId = c.getString("UserId");
}
} catch (JSONException e) {
e.printStackTrace();
}
试试这个代码:
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
userId = jsonObj.getString("UserId");
} catch (JSONException e) {
e.printStackTrace();
}
您的 JSON 字符串中没有数组,因此您将从第一个 JSON 对象获得的对象已经是您的信息所在的位置。
