我写这篇文章是因为我正在将一个PHP web服务客户端转换成C#(VS2010)。
该项目使用Framework4,但web服务在VS2010中被添加为与Framework2兼容的Web Reference with WSDL。
目前,我只在一个经典的webservice上工作(一个Helloworld测试)。
使用C#客户端时,我没有问题,我向web服务发送文本,web服务通过返回文本来响应。Apache服务器没有出现任何错误。
如果我在.htaccess Apache服务器中激活基本身份验证,则在C#客户端中会出现以下错误:
异常:WebException 状态为HTTP 400的错误请求:Bad Request。
在Apache错误日志中,我看到了这一行:
[Thu Feb 02 23:52:06 2012] [error] [client XX.XX.XX.XX] Invalid URI in request

</soap:Body>
</soap:Envelope>
POST /api/helloworld/webservices.php HTTP/1.1
我确定是凭证不起作用,因为当我尝试使用错误的用户名和密码时,我总是得到400 Bad Request。
C#客户端代码如下: // 我们创建WebService WebService mywebservice = new WebService();
// We define BASIC Authentication
CredentialCache myCredentials = new CredentialCache();
NetworkCredential netCred = new NetworkCredential("User1", "Pass1");
myCredentials.Add(new Uri(mywebservice.Url), "Basic", netCred);
myCredentials.PreAuthenticate = true;
mywebservice.Credentials = myCredentials;
// We define the UserAgent
mywebservice.UserAgent = ".NET Framework";
// We call the function of webservice
string retour = mywebservice.bonjour("Tata");
// We show the return
MessageBox.Show(retour, "Retour de l'API", MessageBoxButtons.OK, MessageBoxIcon.Information);
.htaccess文件: # 不显示指向目录的URL目录列表。 Options -Indexes
# Se logue avec un compte AD
AuthType Basic
AuthBasicProvider ldap
AuthName "Acces au webservice"
AuthLDAPURL ldap://127.0.0.1:389/ou=clients,dc=domaine,dc=com?mail
Require valid-user
如果我删除 .htaccess 文件,一切都正常... 但没有身份验证 :(
这是带有 .htaccess(不工作)的请求和响应:

完成无需.htaccess的请求:
同时,完成该请求需执行以下步骤:

非常感谢您对这个复杂问题的帮助,因为我搜索了很多次,都没有找到解决此问题的方法。
