【中文标题】jQuery ajax GET 返回 405 Method Not Allowed【英文标题】:jQuery ajax GET returns 405 Method Not Allowed 【发布时间】:2011-09-25 06:35:34 【问题描述】: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? (我的用户名和密码正确)
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");
【问题讨论】:
两个页面在同一个域中? 您的意思是我的带有此代码的页面与其请求的页面在同一个域中吗?如果是这样,那么不,他们不是。 【参考方案1】:您不能跨域进行 javascript/Ajax 调用(没有一些严重的混乱)。我们过去为此所做的是创建一个本地 jsp 代理,我们使用我们的 javascript 调用它,但它只是对远程 URL 的传递。
这里是一些示例 JSP 代码,它与我用来命中返回 JSON 的 SOLR 实例的代码非常接近。
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();
【讨论】:
这听起来像是一个选项...你有例子吗? @RyanPitts 你有机会尝试一下吗?它对你有用吗? 我发现我的问题是AJAX不能进行跨域调用。我通过 php 解决了这个问题。我使用 PHP 的 cUrl 获取数据并将其打印出来,然后使用 jQuery AJAX 调用保存返回数据的 PHP 页面。不过感谢您的帮助! 我相信这正是我所说和建议的!很高兴一切顺利。【参考方案2】:如果您正在尝试发送跨域请求,请尝试将您的数据类型更改为“jsonp”
