我使用了JSON RPC的链接。我得到了预期的回应。但当我试图解析响应时,它会给我json错误。
我的代码:
JSONEntity entity = new JSONEntity(jsonRequest);
HttpPost request = new HttpPost("http://192.168.1.150/jsondemo12/service.asmx");
request.setEntity(entity);
HttpResponse response = httpClient.execute(request);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity httpEntity = response.getEntity();
InputStream content = httpEntity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(content,"iso-8859-1"),8);
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
content.close();
} else {
Log.e(AndroidJSONActivity.class.toString(), "Failed to download file");
}
strJSONValue=builder.toString();
txtViewParsedValue.append("n+++++++++++++n"+strJSONValue+"n");
try {
parseJSON();
} catch (JSONException e) {
Log.e("error","Error while parsing!!!");
e.printStackTrace();
}
Log.e("response", strJSONValue);
public void parseJSON() throws JSONException
{
String attr1="",attr2="";
jsonObject = new JSONObject(strJSONValue);
JSONArray result = jsonObject.getJSONArray("result"); <- Error in this line!!!
for(int i=0;i < result.length();i++){
JSONObject e = result.getJSONObject(i);
attr1 = "ExhibitorID: "+ e.getString("ExhibitorID");
attr2 = "ExhibitorName: "+e.getString("ExhibitorName");
}
strParsedValue=attr1+"n"+attr2;
Log.d("Parse", attr1);
Log.d("Parse", attr2);
txtViewParsedValue.append("n**********nParsed Value: n");
txtViewParsedValue.append(strParsedValue);
}
我在"strJSONValue"中得到的结果是字符串格式,没有起始和结束双引号。类似:
{"id":2,"result":"[
{"ExhibitorID":42, etc....}
]"}
结果字符串符合要求,但我无法根据要求将字符串解析为JSON对象。它在Logcat:org.json.JSONException: Value <content of the string> at result of type java.lang.String cannot be converted to JSONArray
中给出错误
请帮帮我。感谢
您的结果实际上是返回一个字符串,而不是json数组。如果您的json格式是这样的,它将返回json数组
{
"id": 2,
"result": [
{
"ExhibitorID": 42
}
]
}
目前它的形式是:
{
"id": 2,
"result": "[ {"ExhibitorID":42, etc....} ]"
}
