在我的项目我有网址 这样的:HttpURLConnection的响应不工作
localhost:8080/myproject/examples/12
它包含的Json values..To进入这个领域需要把访问密钥头。
现在,我所做的是:
private String doHttpUrlConnectionAction(String desiredUrl)
throws Exception
{
URL url = null;
BufferedReader reader = null;
StringBuilder stringBuilder;
try
{
// create the HttpURLConnection
url = new URL(desiredUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
// just want to do an HTTP GET here
connection.setRequestMethod("GET");
// connection.setRequestProperty("Content-Type","application/json");
connection.setRequestProperty("API-KEY", "value");
// uncomment this if you want to write output to this url
connection.setDoOutput(true);
// give it 15 seconds to respond
connection.setReadTimeout(15*1000);
connection.connect();
// read the output from the server
// reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder sb = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
sb.append(line);
}
return sb.toString();
}
catch (Exception e)
{
e.printStackTrace();
throw e;
}
finally
{
// close the reader; this can throw an exception too, so
// wrap it in another try/catch block.
if (reader != null)
{
try
{
reader.close();
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}
}
此代码返回输出:正常
Response Code : 200
<table border="0" cellpadding="4" cellspacing="0"><thead><tr><th>status</th><th>statusCode</th><th>data</th></tr></thead><tbody><tr><td statusCode="200" status="1">Array</td></tr></tbody></table>
但是,当我在访问这个httclient代码,我得到的值..
public String ReadHttpResponse(String url){
StringBuilder sb= new StringBuilder();
HttpClient client= new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
httpget.addHeader("API-KEY", "value");
try {
HttpResponse response = client.execute(httpget);
StatusLine sl = response.getStatusLine();
int sc = sl.getStatusCode();
if (sc==200)
{
HttpEntity ent = response.getEntity();
InputStream inpst = ent.getContent();
BufferedReader rd= new BufferedReader(new InputStreamReader(inpst));
String line;
while ((line=rd.readLine())!=null)
{
sb.append(line);
}
// System.out.println(sb.toString());
}
else
{
System.out.println("I didn't get the response!");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return sb.toString();
}
在这里,我得到正确的输出..
HttpUrlConnection
问题在哪里?我在这里做错了什么?我必须使用HttpUrlConnection
。请大家帮助我..
URL是否工作浏览器? –
您必须在请求中添加此标头:urlConnection.setRequestProperty(“Content-Type”,“application/json; odata = verbose”); urlConnection.setRequestProperty(“Accept”,“application/json; odata = verbose”); –
你的代码没有问题,因为你从服务器端获得200。服务器端存在问题,因此您从服务器端获取html代码。请检查服务器端以解决此问题。 – BarmanInfo
