我正在尝试使用 curl 执行 https 发布请求。当我执行此请求时,我既没有收到任何响应,也没有收到任何错误或异常。感谢您提供帮助或任何关于这里出了什么问题的线索。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' \

public static void uploadToFB() {

这是一个不受信任的网络,因此,我在此链接中做了类似下面的操作。
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();
}
}
