我想使用HttpClient(HttpComponents)做一个HttpPost。这是我的代码:HttpPost转义参数
try{
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost post = new HttpPost(
"https://accounts.google.com/o/oauth2/token");
post.addHeader("accept", "application/json");
post.addHeader("Content-Type", "application/json");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("code", new String(code.getBytes(), Charset.forName("UTF-8"))));
nvps.add(new BasicNameValuePair("client_id", "googleClientId"));
nvps.add(new BasicNameValuePair("redirect_uri", "http://localhost:8080/myapp/test"));
nvps.add(new BasicNameValuePair("client_secret", "ClientSecret"));
nvps.add(new BasicNameValuePair("grant_type", "authorization_code"));
post.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
HttpResponse resp = httpClient.execute(post);
if (resp.getStatusLine().getStatusCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ resp.getStatusLine().getStatusCode());
}
BufferedReader br = new BufferedReader(
new InputStreamReader((resp.getEntity().getContent())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
res = res + output;
}
System.out.println(output);
httpClient.getConnectionManager().shutdown();
} catch(Exception e){
e.printStackTrace();
}
System.out.println(res);
我得到一个400
的代码。我怀疑这是因为我设置的所有参数都包含特殊字符,如_ . and /
,它们正在越狱。我怎样才能避免这种情况?或者我错过了真正的问题?

@Nambari这是邮政,所以我无关的网址。 – Dragos
@Nambari我错过了什么?我是否以某种方式在URL中发送参数? – Dragos
