我正在尝试使用curl执行https发布请求。当我执行这个请求时,我既没有得到任何响应,也没有任何错误或异常。感谢您的帮助或任何关于这里出现问题的线索。谢谢
curl命令行格式:
curl -X POST
-F 'image=@filename.png;type=image/png'
-F 'svgz=@filename.svgz;type=image/svg+xml'
-F 'json={
"text" : "Hello world!",
"templateid" : "0010",
"timestamp" : "1342683312",
"location" : [ 37.7793, -122.4192 ],
"facebook" :
{
"id": "738124695",
"access_token": "<VALID_USER_FACEBOOK_TOKEN_WITH_PUBLISH_ACTIONS_PERMISSIONS",
"expiration_date": "1342683312"
}
};type=application/json'
https://sample.com/api/posts
Facebook发布代码:
public static void uploadToFB() {
HttpClient client = getNewHttpClient();
HttpPost httpost = new HttpPost("https://sample.com/api/posts");
httpost.addHeader("image", "filename.png");
httpost.addHeader("svgz", "filename.svgz");
httpost.addHeader("type", "application/json");
httpost.setHeader("Content-type", "application/json");
JSONObject data = new JSONObject();
JSONObject facebook = new JSONObject();
JSONArray location = new JSONArray();
HttpResponse response = null;
try {
data.put("text","Hello world!");
data.put("templateid","0010");
data.put("timestamp","2012-07-08 09:00:45.312195368+00:00");
location.put(37.7793);
location.put( -122.4192);
data.put("location", location);
facebook.put("id", "738124695");
facebook.put("access_token", "AAADdF92joPABAKmRojBuXZAZAP"+
"qF8ZAxM2bM"+
"UnIErUSYZB85y5vIHAZDZD");
facebook.put("expiration_date", "2013-07-07T 22:00:00Z");
data.put("facebook", facebook);
System.out.println(" ---- data ----- "+data);
StringEntity stringEntity = new StringEntity(data.toString());
httpost.setEntity(stringEntity);
try {
response = client.execute(httpost);
System.out.println(" --- response --- "+response);
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if(entity != null) {
// A Simple Response Read
InputStream instream = entity.getContent();
String result = convertStreamToString(instream);
System.out.println(" ---- result ---- "+result);
// Closing the input stream will trigger connection release
instream.close();
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();

} catch (JSONException e) {
e.printStackTrace();

这是一个不受信任的网络,所以,为此,我在这个链接中做了如下的事情。
private static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
BufferedReader in = null;
StringBuffer sb = new StringBuffer();
BufferedReader inPost = null;
try {
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httpost = new HttpPost(mURL);
httpost.setHeader("Accept","*/*");
httpost.setHeader("Content-Type", "application/x-www-form-urlencoded");
List <NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("testkey1", "myvalue1"));
nvps.add(new BasicNameValuePair("testkey2", "myvalue2"));
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httpost);
HttpEntity entity = response.getEntity();
inPost = new BufferedReader(new InputStreamReader(entity.getContent()));
String linePost = "";
String NLPOST = System.getProperty("line.separator");
while ((linePost = inPost.readLine()) != null) {
sb.append(linePost + NLPOST);
}
inPost.close();
if (entity != null) {
entity.consumeContent();
}
httpclient.getConnectionManager().shutdown();
关于此链接的更多信息。。http://www.softwarepassion.com/android-series-get-post-and-multipart-post-requests/
经过一段艰难的时间,我找到了问题的解决方案。现在,使用MultipartEntity
,我可以像下面这样将数据发送到服务器。
HttpClient httpClient = getHttpClient();
HttpPost httpost = new HttpPost("https://sample.com/api/posts");
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile1 = new FileBody(new File("file.png"), "image/png");
mpEntity.addPart("image", cbFile1);
ContentBody cbFile2 = new FileBody(new File("file.svg"), "image/svg+xml");
mpEntity.addPart("svgz", cbFile2);
ContentBody cbFile3 = new StringBody(getJsonData().toString(), "application/json", Charset.forName("UTF-8"));
mpEntity.addPart("json", cbFile3);
httpost.setEntity(mpEntity);
