问题描述
我想将 JSON 文本 {} 发送到网络服务并读取响应.我怎么能从android做到这一点?创建请求对象、设置内容头等步骤是什么
I want to send the JSON text {} to a web service and read the response. How can I do this from android? What are the steps such as creating request object, setting content headers, etc.
我的代码在这里
public void postData(String result,JSONObject obj) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
String json=obj.toString();
try {
HttpPost httppost = new HttpPost(result.toString());
StringEntity se = new StringEntity(obj.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
String temp = EntityUtils.toString(response.getEntity());
Log.i("tag", temp);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
}
我犯了什么错误请纠正我,因为它向我显示了一个错误的请求错误但是当我在海报上发帖时,它显示我的状态为Successfull 200 ok
what mistake i have done plz correct me because it shows me an bad request errorbut when i do post in poster it shows me status as Successfull 200 ok
推荐答案
我用
httppost.setHeader("Content-type", "application/json");
此外,new HttpPost()
将 Web 服务 URL 作为参数.
Also, the new HttpPost()
takes the web service URL as argument.
