远程服务器返回错误：“(405) Method Not Allowed”

Question

After reading different answers against the same thread i tried almost all the options mentioned in their discussions however i am still getting error:

Error No1 : The remote server returned an error: (404) Not Found. OR

Error No2 : The remote server returned an error: (405) Method Not Allowed .

Below is my code:

var httpWebRequest = (HttpWebRequest)WebRequest.Create("URL?Paramter1=pc&user=u1&password=p1");
httpWebRequest.ContentType = "application/json; charset=utf-8";
httpWebRequest.Method = "POST";
httpWebRequest.Accept = "application/json";
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

I receive error on the last line ie

var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

If i use httpWebRequest.Method="GET" i receive the error number 1 as mentioned above and if i use httpWebRequest.Method="Post" i receive the error number 2.

Answer 1

Use:

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "abcxx")]

At your service page where you declare your method, type POST in upper case. I think you are typing in lowercase.

Answer 2

I too face this issue. Root cause of this error is may be mistook endpoint address in web config file..

This is my mistaken web config

<services>
  <service behaviorConfiguration="mexBehavior" name="sample.sample">
    <endpoint address="http://xxx.xxx.x.xxx:9335" binding="basicHttpBinding" contract="sample.Isamplebase" />
    <host>
      <baseAddresses>
        <add baseAddress="http://xxx.xxx.x.xxx:9335" />
      </baseAddresses>
    </host>
  </service>
</services>

It should be like this

<services>
  <service behaviorConfiguration="mexBehavior" name="sample.sample">
    <endpoint address="http://xxx.xxx.x.xxx:9335/sample.svc" binding="basicHttpBinding" contract="sample.Isamplebase" />
    <host>
      <baseAddresses>
        <add baseAddress="http://xxx.xxx.x.xxx:9335" />
      </baseAddresses>
    </host>
  </service>
</services>

Now its working fine... Best is yours.. Good Luck.

Answer 3

My bet is that either Paramter1 or username or password are incorrect - in other words the user you were trying to use doid not exist.

The server returns 404 Not Found , not because you didn't hit the right API method, but because the object you are asking for doesn't exist.

Answer 4

Looking at your code, you create your URL and pass data as url form encoded, but then you set the content type as application/json . I'd think you either:

1. Meant to use application/x-www-form-urlencoded as the content type

or

2. Meant to not send the data in the URL, and instead need to set a JSON body for your POST

Answer 5

I also faced this issue. In my case the reason was in incorrect (incomplete) URL.

I called

60033/COMPANY_NAME/api/Company/MOM/v1.0/companies(5a56e3ea-cd63-ec11-b6ea-6045bd874170)/

But you can't do a POST on the general companies-URL.

I should use URL different headers, depends on my purpose

60033/COMPANY_NAME/api/Company/MOM/v1.0/companies(5a56e3ea-cd63-ec11-b6ea-6045bd874170)/receiptHeaders

When I fixed URL errors are gone
