我在将数据发布到REST WCF服务时遇到了一些困难。我需要向它发送一个json对象/数组,但我的POST方法需要一个Stream,然后将其拆分以获取JSON(不能更改此部分)。
我已在C#中使用以下代码完成此操作:
public static string CallPostService(string url, string data)
{
url = Config.serviceAddress + url;
string json = data;
byte[] buffer = Encoding.UTF8.GetBytes(json);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = "POST";
request.Credentials = new NetworkCredential("user", "pass");
request.ContentType = "application/x-www-form-urlencoded";
using (StreamWriter sw = new StreamWriter(request.GetRequestStream()))
{
sw.Write(json);
Console.WriteLine(json);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
string res = sr.ReadToEnd();
return res;
}
}
我需要一些等效的Java代码来执行此操作,最好使用Apache HttpClient。我是http库的新手,所以我很欣赏一点方向。
编辑:
以下是我的WCF服务的方法标头。请求正文需要是一个流,因此服务可以处理它。
[WebInvoke(Method = "POST", UriTemplate = "person/delete", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
Person DeletePerson(Stream streamdata) { //bla }

检查此代码段。 我真的试过了,但它应该有用
public void postData() {
try {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");
String auth = android.util.Base64.encodeToString(
(username + ":" + password).getBytes("UTF-8"),
android.util.Base64.NO_WRAP
);
httppost.addHeader("Authorization", "Basic "+ auth);
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}

String MyData;// Data need to post to server JSON/XML
String reply;
try {
URLConnection connection = url.openConnection();
HttpURLConnection httppost = (HttpURLConnection) connection;
httppost.setDoInput(true);
httppost.setDoOutput(true);
httppost.setRequestMethod("POST");
httppost.setRequestProperty("User-Agent", "UA Here");
httppost.setRequestProperty("Accept_Language", "en-US");
httppost.setRequestProperty("Content-Type", "content type here");
DataOutputStream dos = new DataOutputStream(httppost.getOutputStream());
dos.write(MyData.getBytes()); // bytes[] b of post data
InputStream in = httppost.getInputStream();
StringBuffer sb = new StringBuffer();
try {
int chr;
while ((chr = in.read()) != -1) {
sb.append((char) chr);
}
reply = sb.toString();
} finally {
in.close();
}
Log.v("POST RESPONSE",reply);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
