如何在Java中发布
我有一些东西看起来像这样:如何在Java中发布,java,post,web,Java,Post,Web,我有一些东西看起来像这样: POST /o/oauth2/token HTTP/1.1 Host: accounts.google.com Content-Type: application/x-www-form-urlencoded grant_type=assertion&assertion_type=http%3A%2F%2Foauth.net%2Fgrant_type%2Fjwt%2F1.0%2Fbearer&assertion=eyJhbGciOiJSUzI1NiIs
POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded
grant_type=assertion&assertion_type=http%3A%2F%2Foauth.net%2Fgrant_type%2Fjwt%2F1.0%2Fbearer&assertion=eyJhbGciOiJSUzI1NiIs
String urlParameters = URLEncoder.encode("grant_type", "UTF-8") + "="+ URLEncoder.encode("assertion", "UTF-8") + "&" + URLEncoder.encode("assertion_type", "UTF-8") + "=" + URLEncoder.encode("http://oauth.net/grant_type/jwt/1.0/bearer", "UTF-8") + "&" + URLEncoder.encode("assertion", "UTF-8") + "=" + URLEncoder.encode(encodedMessage, "UTF-8");
我将如何在Java中使用它?我已经有了所有的信息,所以我不需要解析它
基本上,我需要发布3种不同的数据,使用curl对我很有效,但我需要使用java:
curl -d 'grant_type=assertion&assertion_type=http%3A%2F%2Foauth.net%2Fgrant_type%2Fjwt%2F1.0%2Fbearer&assertion=eyJhbGciOiJSUzI1NiIsInR5i' https://accounts.google.com/o/oauth2/token
我删掉了一些数据,这样更容易阅读,这样就不起作用了
所以一个大问题是curl可以工作,而我尝试的大多数Java教程都会给出HTTP响应错误400
我应该这样编码日期:
POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded
grant_type=assertion&assertion_type=http%3A%2F%2Foauth.net%2Fgrant_type%2Fjwt%2F1.0%2Fbearer&assertion=eyJhbGciOiJSUzI1NiIs
String urlParameters = URLEncoder.encode("grant_type", "UTF-8") + "="+ URLEncoder.encode("assertion", "UTF-8") + "&" + URLEncoder.encode("assertion_type", "UTF-8") + "=" + URLEncoder.encode("http://oauth.net/grant_type/jwt/1.0/bearer", "UTF-8") + "&" + URLEncoder.encode("assertion", "UTF-8") + "=" + URLEncoder.encode(encodedMessage, "UTF-8");
或否:
String urlParameters ="grant_type=assertion&assertion_type=http://oauth.net/grant_type/jwt/1.0/bearer&assertion=" + encodedMessage;
使用此代码:
URL url = new URL(targetURL);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(urlParameters);
writer.flush();
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
writer.close();
reader.close();
使用类似的东西
它可以将预URL编码的数据发布到URI中,虽然我不知道您是否可以抛出一个完整的请求体,但可能需要对其进行解析,但也可能有相应的库。使用类似的方法
它可以将预URL编码的数据发布到URI中,虽然我不知道您是否可以抛出一个完整的请求体,但可能需要对其进行解析,但也可能有相应的库。下面是一个简单的Apache HttpClient示例,其请求体经过了轻微修改,以显示execute的工作原理:
HttpClient client = new HttpClient();
PostMethod post = new PostMethod("http://jakarata.apache.org/");
NameValuePair[] data = {
new NameValuePair("user", "joe"),
new NameValuePair("password", "bloggs")
};
post.setRequestBody(data);
int returnCode = client.execute(post);
// check return code ...
InputStream in = post.getResponseBodyAsStream();
