android上带授权的HTTP POST请求
android上带授权的HTTP POST请求
提问于 2011-02-23 22:58:44
当我用来自HttpPost的setHeader设置"Authorization“头时，主机名从请求中消失，并且总是返回错误400 (错误请求)。同样的代码在纯java (没有android)上工作得很好，当我在android上删除设置" authorization“头时，它工作得很好，但我需要授权。这是一个代码(域已更改)：
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://myhost.com/test.php");
post.setHeader("Accept", "application/json");
post.setHeader("User-Agent", "Apache-HttpClient/4.1 (java 1.5)");
post.setHeader("Host", "myhost.com");
post.setHeader("Authorization",getB64Auth());
List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("data[body]", "test"));
AbstractHttpEntity ent=new UrlEncodedFormEntity(nvps, HTTP.UTF_8);
ent.setContentType("application/x-www-form-urlencoded; charset=UTF-8");
ent.setContentEncoding("UTF-8");
post.setEntity(ent);
post.setURI(new URI("http://myhost.com/test.php"));
HttpResponse response =client.execute(post);方法getB64Auth()返回使用Base64编码的"login:password“，例如："YnxpcYRlc3RwMTulHGhlSGs=”，但这并不重要。
这是在纯java上调用上述代码时lighttpd的一段error.log：
2011-02-23 15:37:36: (request.c.304) fd: 8 request-len: 308
POST /test.php HTTP/1.1
Accept: application/json
User-Agent: Apache-HttpClient/4.1 (java 1.5)
Host: myhost.com
Authorization: Basic YnxpcYRlc3RwMTulHGhlSGs=
Content-Length: 21
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
Content-Encoding: UTF-8
Connection: Keep-Alive
HTTP/1.1 200 OK
Content-type: text/html
Transfer-Encoding: chunked和来自access.log的记录(IP已更改)：
1.1.1.1 myhost.com - [23/Feb/2011:15:37:36 +0100] "POST /test.php HTTP/1.1" 200 32 "-" "Apache-HttpClient/4.1 (java 1.5)"当在android上调用相同的代码时，我在日志中得到如下内容：
POST /test.php HTTP/1.1
Accept: application/json
User-Agent: Apache-HttpClient/4.1 (java 1.5)
Host: myhost.com
Authorization: Basic YnxpcYRlc3RwMTulHGhlSGs=
Content-Length: 21
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
Content-Encoding: UTF-8
Connection: Keep-Alive
Expect: 100-Continue
2011-02-23 15:45:10: (response.c.128) Response-Header:
HTTP/1.1 400 Bad Request
Content-Type: text/html
Content-Length: 349
Connection: closeaccess.log：
1.1.1.1 - - [23/Feb/2011:15:45:10 +0100] "POST /test.php HTTP/1.1" 400 349 "-" "Apache-HttpClient/4.1 (java 1.5)"如何在android上使用POST获得授权？当我使用HttpURLConnection而不是HttpClient时，这是没有区别的。

感谢Samuh的提示:)插入了一个额外的换行符，它在GET请求中没有意义，但在POST请求中很重要。这是在android中生成Authorization头部的正确方式(本例中为getB64Auth )：
private String getB64Auth (String login, String pass) {
String source=login+":"+pass;
String ret="Basic "+Base64.encodeToString(source.getBytes(),Base64.URL_SAFE|Base64.NO_WRAP);
return ret;
}缺少Base64.NO_WRAP标志。

简单地使用这个：
String authorizationString = "Basic " + Base64.encodeToString(
("your_login" + ":" + "your_password").getBytes(),
Base64.NO_WRAP); //Base64.NO_WRAP flag
post.setHeader("Authorization", authorizationString);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
