Exception：org.json.JSONException：java.lang.String类型的值无法在android中转换为JSONObject

Question

API响应：

{
  "Response": {
    "message": "Success",
    "url": "http://makemyreport.com/MobileApps/",
    "cor": "DEMO",
    "headerMsg": "DEMO",
    "subheadMsg": "DEMO"
  }
}

Asynctask代码：

JSONObject jsonObject = new JSONObject(response);
JSONObject responseObj = jsonObject.getJSONObject("Response");
message = responseObj.getString("message");
String url = responseObj.getString("url");
orgId = responseObj.getString("cor");
orgName = responseObj.getString("headerMsg");
String subheadMsg = responseObj.getString("subheadMsg");

记录猫错误：

Exception: org.json.JSONException: Value  of type java.lang.String cannot be converted to JSONObject 

谁能帮我解决这个问题？ 提前致谢。

在try catch块中实现它，还检查您的响应字符串是否具有期望值：

try {
    JSONObject jsonObject = new JSONObject(response);
    JSONObject responseObj = jsonObject.getJSONObject("Response");
    message = responseObj.getString("message");
    String url = responseObj.getString("url");
    orgId = responseObj.getString("cor");
    orgName = responseObj.getString("headerMsg");
    String subheadMsg = responseObj.getString("subheadMsg");

} catch (JSONException e) {
    e.printStackTrace();
    Toast.makeText(getApplicationContext(), "Error: " + e.getMessage(),
                    Toast.LENGTH_LONG).show();              
}
