如何在JAVA中使用HTTP发送标头
我有这个命令如何在JAVA中使用HTTP发送标头,java,apache-httpclient-4.x,Java,Apache Httpclient 4.x,我有这个命令 # curl --header "Authorization: key=$api_key" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{\"registration_ids\":[\"ABC\"]}" 它正在我的设备中发送推送通知。现在我正在尝试用java发送它,但我的代码不起作用 String body = "{\"registration_ids\
# curl --header "Authorization: key=$api_key" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{\"registration_ids\":[\"ABC\"]}"
它正在我的设备中发送推送通知。现在我正在尝试用java发送它,但我的代码不起作用
String body = "{\"registration_ids\":[\"ABC\"]}";
HttpPost httppost = new HttpPost("https://android.googleapis.com/gcm/send");
StringEntity stringentity = new StringEntity(body, "UTF-8");
httppost.addHeader("Content-Type","application/json");
httppost.addHeader("Authorization: key", "AIza*********YUI");
httppost.setEntity(stringentity);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
try {
response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String strresponse = null;
if (entity != null) {
strresponse = EntityUtils.toString(entity);
System.out.println("strresponse = "+strresponse);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
我不知道我错过了什么。此文档告诉我需要发送带有正文的标题。根据您的
curl
示例,这应该是您的授权
标题:
httppost.addHeader("Authorization", "key=AIza*********YUI");
这将解决您的问题。我刚刚用引用的确认了这个标题。你是什么意思,但是
但是我的代码不是?是否有任何异常被抛出?你经历过什么结果吗?如果你不告诉我们到底出了什么问题,我们怎么帮你?
