先上需求：

使用webdav上行檔案之前，需要建立目錄。

坑在哪裡：

http 4.0以後http不再支援excutemethod的方法。不能直接呼叫mkcol方法進行目錄建立。

解決的辦法：

檢視開源庫：

https://github.com/lookfirst/sardine的實現：

使用下面的程式碼自己建立mkcol的類。

static class HttpMkCol extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "MKCOL";

    public HttpMkCol(String url) {
        this
 
(URI.create(url));
    }

    public HttpMkCol(URI url) {
        this.setURI(url);
    }

    @Override
public String getMethod() {
        return METHOD_NAME;
    }
}

HttpMkCol mkCol = new HttpMkCol(sUrl);

try {
    HttpResponse response = httpClient.execute(mkCol, context);

個人參考了一下：

public class HttpPut extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "PUT";

    public HttpPut() {
        throw new RuntimeException("Stub!");
    }

    public HttpPut(URI uri) {
        throw new RuntimeException("Stub!");
    }

    public HttpPut(String uri) {
        throw new 
 
RuntimeException("Stub!");
    }

    public String getMethod() {
        throw new RuntimeException("Stub!");
    }
}
