我正在尝试访问需要身份验证的API.这是我正在使用的代码但我不断收到405 Method Not Allowed错误.有什么想法吗？ (我的用户名和密码是正确的)
function basic_auth(user,pass){
var tok = user + ':' + pass;
var hash = $.base64.encode(tok);
return "Basic " + hash;
}
var auth = basic_auth('username','password');
var releaseName1 = "11.6.3";
var releaseName2 = "11.6.3 Confirmed";
$.ajax({
type: "GET",url: "https://www10.v1host.com/Company/rest-1.v1/Data/Story?sel=Description,Number,Name,TimeBox.Name,Parent,AssetState&where=Custom_Release2.Name='"+releaseName1+"','"+releaseName2+"';AssetState='64'",beforeSend: function(xhr){
xhr.setRequestHeader('Authorization',auth);
},dataType: "xml",async: false,success: parseXml
});
function parseXml(xml){
$(xml).find("item");
}
解决方法
你不能跨域进行javascript / Ajax调用(没有严重的kludging).我们过去为此做的是创建一个我们用javascript调用的本地jsp代理,但它只是远程URL的传递.
下面是一些示例JSP代码,它接近于我用来返回返回JSON的SOLR实例.
final String ENCODING = "UTF-8"; // this is the default unless specified otherwise (in server.xml for Tomcat)
// see http://tomcat.apache.org/tomcat-6.0-doc/config/http.html#Common_Attributes and
// http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q2
final String URI_ENCODING = "ISO-8859-1";
HashMap<String,String> defaultSettings = new HashMap<String,String>() {
{
put("wt","json");
put("rows","10");
put("start","0");
}
};
BufferedReader searchResponse = null;
OutputStreamWriter forwardedSearchRequest = null;
// TODO: are there any headers that we need to pass on?
// simply pass on the request to the search server and return any results
try {
URL searchURL = new URL("http://yourdestinationurlhere.com");
HttpURLConnection conn = (HttpURLConnection) searchURL.openConnection();
// read the request data and send it as POST data (unchanged)
conn.setDoOutput(true);
forwardedSearchRequest = new OutputStreamWriter(conn.getOutputStream());
// at least for Tomcat 6.0,the default is really iso-8859-1,although it is reported as UTF-8
// so,we will explicitly set it to URI_ENCODING in both places
request.setCharacterEncoding(URI_ENCODING);
String query = (String) request.getParameter("q");
if ((query != null) && (! "".equals(query.trim()))) {
query = URLEncoder.encode(query,request.getCharacterEncoding()); // we must use the same setting as the container for URI-encoding
forwardedSearchRequest.write("&q=");
forwardedSearchRequest.write(query);
} else {
// empty queries may return all results,so let's circumvent that
forwardedSearchRequest.write("&q=help");
}
for(String key:defaultSettings.keySet()) {
String resultType = (String) request.getParameter(key);
if ((resultType == null) || "".equals(resultType.trim())) resultType = defaultSettings.get(key);
forwardedSearchRequest.write("&"+key+"=");
forwardedSearchRequest.write(resultType);
}
forwardedSearchRequest.flush();
// read and forward the response
// reset anything that may have been sent so far
out.clearBuffer();
// do this only if we have a 200 response code
if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
// the web server may be running as windows-1252,so let's ensure we have the right CS
searchResponse = new BufferedReader(new InputStreamReader(conn.getInputStream(),ENCODING));
String contentType = conn.getHeaderField("Content-Type");
if ((contentType != null) && (! "".equals(contentType))) response.setHeader("Content-Type",contentType);
String buffer;
while ((buffer = searchResponse.readLine()) != null) out.println(buffer);
} else {
// dish out a mock-Solr-JSON response that includes a status and an error
response.setHeader("Content-Type","application/json");
out.println("{ responseHeader: {status: -1,responseCode: " + conn.getResponseCode() +
",responseMessage: \"" + conn.getResponseMessage() + "\" } }");
}
} catch (Exception e) {
throw new ServletException("Exception - " + e.getClass().getName(),e);
} finally {
if (forwardedSearchRequest != null) forwardedSearchRequest.close();
if (searchResponse != null) searchResponse.close();
}
