demo1: http request several different ways Summary:
-------------------------------------------------------------------------------------------------
Post a new version of the request method:
Based version:
<!--<!– https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient –>--> <!--<dependency>--> <!--<groupId>org.apache.httpcomponents</groupId>--> <!--<artifactId>httpclient</artifactId>--> <!--<version>4.5.5</version>--> <!--</dependency>-->
// String uploadResponse = Request.Post(nodeAddress + "/" + bucketName + "/" + objectName)
// .addHeader("x-nos-token", uploadToken)
// .bodyByteArray(chunkData, 0, readLen)
// .execute()
// .returnContent()
// .toString();
-------------------------------------------------------------------------------------------------
Post request version way:
// public static String the doPost (URL String, String token, byte [] the chunk, OFF int, int len) // { // CloseableHttpClient httpClient = null; // CloseableHttpResponse the httpResponse = null; // String Result = ""; / / // Create instance httpClient @ httpClient HttpClients.createDefault = (); // // Create instance HttpPost remote connection @ HttpPost HttpPost = new new HttpPost (URL); // // configuration request parameter examples // RequestConfig requestConfig = RequestConfig .custom (). setConnectTimeout (35000) // set the connection timeout hosting services // .setConnectionRequestTimeout (35000) // set the connection request time // .setSocketTimeout (60000) // set the read data connection timeout // .build (); // // setting to httpPost instance // httpPost.setConfig ( requestConfig); // // set the request header // httpPost.addHeader ( "X-NOS-token", token); // // package post request parameter // // set the parameters for the encapsulated request HttpPost // the HttpEntity = new new ByteArrayEntity RequestEntity (the chunk, 0, len); // httpPost.setEntity (RequestEntity); // // the try { // // httpClient post requests on the object, the object parameters and returns a response // the httpResponse = httpClient.execute (HttpPost); // // get a response from the response object content // the HttpEntity = httpResponse.getEntity Entity (); // = EntityUtils.toString Result (Entity); // } the catch (ClientProtocolException E) { // e.printStackTrace (); // } the catch (IOException E) { // e.printStackTrace (); // } the finally { // // Close the resource // IF (null! = httpResponse) { // the try { // httpResponse.close(); // } catch (IOException e) { // e.printStackTrace(); // } // } // if (null != httpClient) { // try { // httpClient.close(); // } catch (IOException e) { // e.printStackTrace(); // } // } // } // return result; // }
-------------------------------------------------------------------------------------------------
Post request version way:
sendPost static String public (URL String, String token, byte [] the chunk, OFF int, int len)
{
// create an object instance httpClient
HttpClient HttpClient httpClient new new = ();
// set timeout host servers httpClient: 15000 milliseconds
httpClient .getHttpConnectionManager () the getParams () setConnectionTimeout (15000);..
// Create instance object request method post
a PostMethod PostMethod a PostMethod new new = (URL);
// set the post request time
postMethod.getParams () setParameter (HttpMethodParams.SO_TIMEOUT,. 60000);
postMethod.addRequestHeader ( "X-NOS-token", token);
the try {
// JSON format parameter parsing
RequestEntity = new new ByteArrayRequestEntity Entity (the chunk);
postMethod.setRequestEntity (Entity);
httpClient.executeMethod(postMethod);
String result = postMethod.getResponseBodyAsString();
postMethod.releaseConnection();
return result;
} catch (IOException e) {
logger.info("POST请求发出失败!!!");
e.printStackTrace();
}
return null;
}

A GET request method:
the doGet static String public (the HTTPUrl String)
{
the HttpURLConnection Connection = null;
the InputStream IS = null;
the BufferedReader br = null;
// returns the resulting string
String Result = null;
the try {
// create a remote connection object url
URL url = new URL ( the HTTPUrl);
// open a connection object via the remote connection url, turn into strong class httpURLConnection
connection = (the httpURLConnection) url.openConnection ();
// set the connection mode: GET
connection.setRequestMethod ( "the GET");
// set the connection the host server timeout time: 15000 milliseconds
connection.setConnectTimeout (15,000);
// set the read data to return the remote time: 60000 milliseconds
connection.setReadTimeout (60,000);
// send a request
connection.connect ();
// connected by connection, takes an input stream
IF (connection.getResponseCode () == 200 is) {
IS = connection.getInputStream ();
// input stream IS package, and to specify the character set
br = new BufferedReader (new new the InputStreamReader (IS, "UTF-. 8"));
// store data
the StringBuffer SBF the StringBuffer new new = ();
String TEMP = null;
the while (! (br.readLine TEMP = ()) = null) {
sbf.append (TEMP);
sbf.append ( "\ R & lt \ n-");
}
Result sbf.toString = ();
}
} the catch (a MalformedURLException E) {
logger.error ( "illegal address format exception ...");
e.printStackTrace ();
} the catch (IOException E) {
logger.error ( "IO streams in the Get Request abnormality");
e.printStackTrace ();
} the finally {
// Close the resource
IF (br = null!) {
the try {
br.close ();
} the catch (IOException E) {
e.printStackTrace ();
}
}
IF (! IS = null) {
the try {
is.close ();
} the catch (IOException E) {
e.printStackTrace () ;
}
}
connection.disconnect (); // Close remote connection
}
return Result;
}

Recording process issues:
When using get request, if the request parameters in the URL contains special characters, special characters need to be escaped:
Some characters have special meaning in a URL, the basic encoding rules are as follows: a special meaning hexadecimal value of 1 . + Represents a space (no spaces in the URL)% 20 2 ./ separate directories and subdirectories% 2F 3 separate reality.? URL and the parameter% 3F . 4 .%% specify special character 25 . 5 . #% indicates bookmark 23 is . 6 . & separator between the parameters specified in the URL% 26
Solution:
//对鉴权参数做AES加密处理 requestId = java.net.URLEncoder.encode( AESCryptUtils.encode(requestId) ); data = java.net.URLEncoder.encode( AESCryptUtils.encode(data) ); action = java.net.URLEncoder.encode( AESCryptUtils.encode(action) ); String URL = AUTH_URL + "?" + "data=" + data + "&requestId=" + requestId + "&action=" + action;
