What will be the equivalent to following curl command in java
提问by Kashif Ali
i need to convert the following curl command into java command.
我需要将以下 curl 命令转换为 java 命令。
$curl_handle = curl_init ();
curl_setopt ($curl_handle, CURLOPT_URL,$url);`enter code here`
curl_setopt ($curl_handle, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($curl_handle, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($curl_handle, CURLOPT_POST, 1);
curl_setopt ($curl_handle, CURLOPT_POSTFIELDS, $postfields);
//echo $postfields;
$curl_result = curl_exec ($curl_handle) or die ("There has been a CURL_EXEC error");

Http(s)UrlConnectionmay be your weapon of choice:
Http(s)UrlConnection可能是您选择的武器：
public String sendData() throws IOException {
// curl_init and url
URL url = new URL("http://some.host.com/somewhere/to/");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
// CURLOPT_POST
con.setRequestMethod("POST");
// CURLOPT_FOLLOWLOCATION
con.setInstanceFollowRedirects(true);
String postData = "my_data_for_posting";
con.setRequestProperty("Content-length", String.valueOf(postData.length()));
con.setDoOutput(true);
con.setDoInput(true);
DataOutputStream output = new DataOutputStream(con.getOutputStream());
output.writeBytes(postData);
output.close();
// "Post data send ... waiting for reply");
int code = con.getResponseCode(); // 200 = HTTP_OK
System.out.println("Response (Code):" + code);
System.out.println("Response (Message):" + con.getResponseMessage());
// read the response
DataInputStream input = new DataInputStream(con.getInputStream());
int c;
StringBuilder resultBuf = new StringBuilder();
while ( (c = input.read()) != -1) {
resultBuf.append((char) c);
}
input.close();
return resultBuf.toString();
}
I'm not quite sure about the HTTPS_VERIFYPEER-thing, but this may give you a starting point.
我不太确定HTTPS_VERIFYPEER-thing，但这可能会给你一个起点。

Have a look at the java.net.URL and java.net.URLConnection libraries.
查看 java.net.URL 和 java.net.URLConnection 库。
URL url = new URL("yourUrl.com");
Then use a an InputStreamReader & BufferedReader.
然后使用 InputStreamReader 和 BufferedReader。
