我正在尝试使用以下代码执行以下链接:
class httpget{
HttpGet httpGet=null;
public void linkexecute(){
String url="http://<server>/<path>/action=send&msg=new message";
httpGet= new HttpGet(url); // line 1
....
}
at line 1 it is giving error "Illegal arguement exception"
java.lang.IllegalArgumentException: Illegal character in query at index 77: http://<server>/<path>/sms.json?action=send&msg=new message
at java.net.URI.create(URI.java:970)
at org.apache.http.client.methods.HttpGet.<init>(HttpGet.java:75)
at com.sms.login.LoginService.sendSms(LoginService.java:143)
鉴于以下网址没有错误,“msg =”
的字词没有空白String url="http://<server>/<path>/action=send&msg=newmessage";
如何解决网址中字数差距的问题?

在这里,我给你一个功能,将从网址中删除所有无效字符。请在此函数中传递您的网址,您将获得一个带编码字符串的新网址。
public static String convertURL(String str) {
String url = null;
try{
url = new String(str.trim().replace(" ", "%20").replace("&", "%26")
.replace(",", "%2c").replace("(", "%28").replace(")", "%29")
.replace("!", "%21").replace("=", "%3D").replace("<", "%3C")
.replace(">", "%3E").replace("#", "%23").replace("$", "%24")
.replace("'", "%27").replace("*", "%2A").replace("-", "%2D")
.replace(".", "%2E").replace("/", "%2F").replace(":", "%3A")
.replace(";", "%3B").replace("?", "%3F").replace("@", "%40")
.replace("[", "%5B").replace("\\", "%5C").replace("]", "%5D")
.replace("_", "%5F").replace("`", "%60").replace("{", "%7B")
.replace("|", "%7C").replace("}", "%7D"));
}catch(Exception e){
e.printStackTrace();
}
return url;
}

你绝对应该使用URLEncoder.encode(String, String)
答案 2 :(得分:5)
我认为问题在于URL的参数。而不是编码或替换整个URL,只需对参数进行编码,如下所示:
Url: http://myHost.com/mail.do?address=New York city@&time=12$3;
right url:http://myHost.com/mail.do? + UrlEncode(address) + "&" + UrlEncode(time);
另一个例子是:
Map<String, String> params = new HashMap<String, String>();
params.put("email", URLEncoder.encode(loginStr));
params.put("pass", URLEncoder.encode(passwStr));
Model.doAuthUser(params, userCallback);
Model.doAuthUser喜欢以下内容:
String url = "http://myHost.com/mail.do";
if (params != null) {
url += "?";
Boolean beginAddParams = true;
for (Entry<String, String> entryParams : params.entrySet()) {
if (!beginAddParams) {
url +="&";
} else {
beginAddParams = false;
}
url += entryParams.getKey() + "=" + entryParams.getValue();
}
并在任意位置使用url
。

我认为你应该使用%20而不是空格
答案 4 :(得分:1)
当我将变量发布到我的webservice时,URLEncoder对我来说没有用,因为它正在替换所有参数。我最终使用
URI uri = new URI("http", "server", "/path", "action=send&msg=newmessage", null);
String url = uri.toASCIIString();
以及之后使用httpClient和httpClient解析我下载的数据...
String xml = null;
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
xml = EntityUtils.toString(httpEntity);
我认为httpGet方法的工作方式相同。
