以URL为参数的HTTP Post请求

Question

I need send https request to server using parameters one of them is URL: I do next:

HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(APIURL);
    httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("url", "https://api/v1/pictureadress/id"));
 ...

And I got error when add URL parameter. But if I add other parameters, except url, like age, gender etc. I have no errors. WHat I do wrong?

Answer 1

I have no exposure to apache component libraries. But looking at the api on BasicNameValuePair , I understand that the input name and values are stored raw and not encoded . I fear that is the reason why your url parameter's value threw an error. You may require UrlEncodedFormEntity unless already using to handle url encoded name value pairs.

Answer 2

Try this..

public void postData() throws Exception {


 HttpClient client = new DefaultHttpClient();
 HttpPost httppost = new HttpPost("http://www.xyz.com");

 List<NameValuePair> list = new ArrayList<NameValuePair>(1);

 list.add(new BasicNameValuePair("name","ABC");

 httppost.setEntity(new UrlEncodedFormEntity(list));

 HttpResponse r = client.execute(httppost);

}
