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"));
 ...

我加入 URL 参数时出错。但如果我加入其它参数, 除了 URL, 比如年龄, 性别等等。我没有错误。我做错了吗?

Answer 1

我没有接触到 apache 组件库。但是, 在 < a href= > 上查看 < http:// www.docjar. org/docs/ api/ apache/ http/ message/ BasicName ValuePair.html" rel= "nofollow" > 基本名 ValuePair , 我理解输入的名称和值是原始存储的,而不是 < em> encoded < /em> 。恐怕这就是为什么您的 < code> url 参数的价值抛出错误的原因。您可能需要 < a href=" http://hc.apache.org/ httpsuppres-client-ga/ httpclient/apicos/org/apache/ http/client/entity/ UrlEncodedFormentity.html" " rel=" "nofol " > > > > > 。除非已经使用处理 ur ecocodedfordd FormentFormentity

试试这个...

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);

}
