A JSONObject text must begin with '{' at 1 [character 2 line 1] with '{' error

Question

String JSON = \"http://www.json-generator.com/j/cglqaRcMSW?indent=4\";

JSONObject jsonObject = new JSONObject(JSON);
JSONObject getSth = jsonObject.getJSONObject(\"         


        

Answer 1

I had the same, there was an empty new line character at the beginning. That solved it:

int i = result.indexOf("{");
result = result.substring(i);
JSONObject json = new JSONObject(result.trim()); 
System.out.println(json.toString(4));  

Answer 2

Your problem is that String JSON = "http://www.json-generator.com/j/cglqaRcMSW?indent=4"; is not JSON.
What you want to do is open an HTTP connection to "http://www.json-generator.com/j/cglqaRcMSW?indent=4" and parse the JSON response.

String JSON = "http://www.json-generator.com/j/cglqaRcMSW?indent=4";
JSONObject jsonObject = new JSONObject(JSON); // <-- Problem here!

Will not open a connection to the site and retrieve the content.

Answer 3

I had similar issue due to a small mistake, when i was trying to convert a List to json. If a List is converted to json it will return JSONArray not JSONObject.

Answer 4

in my case my arraylist trhows me that error with the JSONObject , but i fin this solution for my array of String objects

List<String> listStrings= new ArrayList<String>();
String json = new Gson().toJson(listStrings);
return json;

Works like charm with angular Gson version 2.8.5

Answer 5

In my case the json file encoding was a problem

I was generating JSON file in vb .net with following: My.Computer.FileSystem.WriteAllText("newComponent.json", json.Trim, False)

And I tried all suggestions in this post but none helped.

Eventually in Notepad++ noticed that the file created was in UTF-8-BOM

Not sure how it picked up that encoding but after I switched the encoding to UTF-8, it resolved with no other changes.

Hope this helps someone.

Your JSON is perfectly valid. Try using these JSON classes to parse it. http://json.org/java/
