android – Volley – 如何发送DELETE请求参数？

同样的问题在这里,但我找到了@L_772_9@案

问题是在com.android.volley.toolBox.httpClientStack.java中实现createhttprequest方法,只有在请求方法为POST,PUT或PATCH时才会添加该主体.

/**
 * Creates the appropriate subclass of httpUrirequest for passed in request.
 */
@SuppressWarnings("deprecation")
/* protected */ static httpUrirequest createhttprequest(request<?> request,Map<String,String> additionalHeaders) throws AuthFailureError {
    switch (request.getmethod()) {
        case Method.DEPRECATED_GET_OR_POST: {
            // This is the deprecated way that needs to be handled for BACkWARDs compatibility.
            // If the request's post body is null,then the assumption is that the request is
            // GET.  Otherwise,it is assumed that the request is a POST.
            byte[] postBody = request.getPostBody();
            if (postBody != null) {
                httpPost postrequest = new httpPost(request.getUrl());
                postrequest.addHeader(HEADER_CONTENT_TYPE,request.getPostBodyContentType());
                httpentity entity;
                entity = new ByteArrayEntity(postBody);
                postrequest.setEntity(entity);
                return postrequest;
            } else {
                return new httpGet(request.getUrl());
            }
        }
        case Method.GET:
            return new httpGet(request.getUrl());
        case Method.deletE:
            return new httpdelete(request.getUrl());
        case Method.POST: {
            httpPost postrequest = new httpPost(request.getUrl());
            postrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
            setEntityIfNonEmptyBody(postrequest,request);
            return postrequest;
        }
        case Method.PUT: {
            httpPut putrequest = new httpPut(request.getUrl());
            putrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
            setEntityIfNonEmptyBody(putrequest,request);
            return putrequest;
        }
        case Method.HEAD:
            return new httpHead(request.getUrl());
        case Method.oPTIONS:
            return new httpOptions(request.getUrl());
        case Method.TRACE:
            return new httpTrace(request.getUrl());
        case Method.PATCH: {
            httpPatch patchrequest = new httpPatch(request.getUrl());
            patchrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
            setEntityIfNonEmptyBody(patchrequest,request);
            return patchrequest;
        }
        default:
            throw new IllegalStateException("UnkNown request method.");
    }
}

所以你必须使用自己的httpStack.java实现,或者你重写httpClientStack类.

首先你应该替换你的初始化requestQueue

requestQueue requestQueue = Volley.newrequestQueue(sContext);

至

String userAgent = "volley/0";
    try {
        String packagename = getContext().getPackagename();
        PackageInfo info = getContext().getPackageManager().getPackageInfo(packagename,0);
        userAgent = packagename + "/" + info.versionCode;
    } catch (PackageManager.NameNotFoundException E) {}
    httpStack httpStack = new OwnhttpClientStack(@L_874_19@.newInstance(userAgent));
    requestQueue requesQueue = Volley.newrequestQueue(sContext,httpStack);

并编写您自己的httpClientStack实现,您可以在createhttprequest()方法中更改“Method.POST：”的大小写.您还必须创建一个像“Ownhttpdelete”这样的对象,作为httpentityEnclosingrequestBase的扩展,使用方法setEntityIfNonEmptyBody().

public class OwnhttpClientStack extends com.android.volley.toolBox.httpClientStack {
    private final static String HEADER_CONTENT_TYPE = "Content-Type";

    public OwnhttpClientStack(httpClient client) {
        super(client);
    }

    @Override
    public httpResponse performrequest(request<?> request,String> additionalHeaders)
            throws IOException,AuthFailureError {
        httpUrirequest httprequest = createhttprequest(request,additionalHeaders);
        addHeaders(httprequest,request.getHeaders());
        onPreparerequest(httprequest);
        httpParams httpParams = httprequest.getParams();
        int timeoutms = request.getTimeoutms();
        // TODO: Reevaluate this connection timeout based on more wide-scale
        // data collection and possibly different for wifi vs. 3G.
        httpconnectionParams.setConnectionTimeout(httpParams,5000);
        httpconnectionParams.setSoTimeout(httpParams,timeoutms);
        return mClient.execute(httprequest);
    }

    private static void addHeaders(httpUrirequest httprequest,String> headers) {
        for (String key : headers.keySet()) {
            httprequest.setHeader(key,headers.get(key));
        }
    }

    static httpUrirequest createhttprequest(request<?> request,String> additionalHeaders) throws AuthFailureError {
        switch (request.getmethod()) {
            case request.Method.DEPRECATED_GET_OR_POST: {
                byte[] postBody = request.getPostBody();
                if (postBody != null) {
                    httpPost postrequest = new httpPost(request.getUrl());
                    postrequest.addHeader(HEADER_CONTENT_TYPE,request.getPostBodyContentType());
                    httpentity entity;
                    entity = new ByteArrayEntity(postBody);
                    postrequest.setEntity(entity);
                    return postrequest;
                } else {
                    return new httpGet(request.getUrl());
                }
            }
            case request.Method.GET:
                return new httpGet(request.getUrl());
            case request.Method.deletE:
                Ownhttpdelete deleterequest =  new Ownhttpdelete(request.getUrl());
                deleterequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
                setEntityIfNonEmptyBody(deleterequest,request);
                return deleterequest;
            case request.Method.POST: {
                httpPost postrequest = new httpPost(request.getUrl());
                postrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
                setEntityIfNonEmptyBody(postrequest,request);
                return postrequest;
            }
            case request.Method.PUT: {
                httpPut putrequest = new httpPut(request.getUrl());
                putrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
                setEntityIfNonEmptyBody(putrequest,request);
                return putrequest;
            }
            case request.Method.HEAD:
                return new httpHead(request.getUrl());
            case request.Method.oPTIONS:
                return new httpOptions(request.getUrl());
            case request.Method.TRACE:
                return new httpTrace(request.getUrl());
            case request.Method.PATCH: {
                httpPatch patchrequest = new httpPatch(request.getUrl());
                patchrequest.addHeader(HEADER_CONTENT_TYPE,request.getBodyContentType());
                setEntityIfNonEmptyBody(patchrequest,request);
                return patchrequest;
            }
            default:
                throw new IllegalStateException("UnkNown request method.");
        }
    }

    private static void setEntityIfNonEmptyBody(httpentityEnclosingrequestBase httprequest,request<?> request) throws AuthFailureError {
        byte[] body = request.getBody();
        if (body != null) {
            httpentity entity = new ByteArrayEntity(body);
            httprequest.setEntity(entity);
        }
    }

    private static class Ownhttpdelete extends httpPost {
        public static final String METHOD_NAME = "deletE";

        public Ownhttpdelete() {
            super();
        }

        public Ownhttpdelete(URI uri) {
            super(uri);
        }

        public Ownhttpdelete(String uri) {
            super(uri);
        }

        public String getmethod() {
            return METHOD_NAME;
        }
    }
}

我希望我的代码能帮助某人.还可以向HEAD请求中添加参数.
