来自 Android 的 HTTP 补丁请求

Question

我正在尝试从 Android 应用程序发出 HTTP Patch 请求，但无法弄清楚。 HTTPUrlConnection 似乎不支持 PATCH。 HttpPatch 似乎不在 Android (link) 上包含的库中。有什么想法吗？

Answer 1

如果绝对需要 Patch 方法，则必须将 Apache HttpClient 作为 jar 依赖项导入。这将在一定程度上增加您的应用程序的大小，但这应该不是一个大问题。

作为一种解决方法，您可以尝试在您的应用中仅包含此 java 代码：

/**
 * HTTP PATCH method.
 * <p>
 * The HTTP PATCH method is defined in <a
 * href="http://tools.ietf.org/html/rfc5789">RF5789</a>: <blockquote> The PATCH
 * method requests that a set of changes described in the request entity be
 * applied to the resource identified by the Request- URI. Differs from the PUT
 * method in the way the server processes the enclosed entity to modify the
 * resource identified by the Request-URI. In a PUT request, the enclosed entity
 * origin server, and the client is requesting that the stored version be
 * replaced. With PATCH, however, the enclosed entity contains a set of
 * instructions describing how a resource currently residing on the origin
 * server should be modified to produce a new version. </blockquote>

public class HttpPatch extends HttpEntityEnclosingRequestBase {

    public final static String METHOD_NAME = "PATCH";

    public HttpPatch() {
        super();
    }

    public HttpPatch(final URI uri) {
        super();
        setURI(uri);
    }

    public HttpPatch(final String uri) {
        super();

    }

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

}

Answer 2

我们创建了自己的 HttpPatch 类，例如：

public class HttpPatch extends HttpPost {
    public static final String METHOD_PATCH = "PATCH";

    public HttpPatch(final String url) {
        super(url);
    }

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

Answer 3

OkHttp 好像支持补丁

Request request = Request.Builder().url().patch().build();

Answer 4

它太棒了。它的作用就像一个魅力。

使用 HttpPost 调用并将标头设置为

httpost.setHeader("X-HTTP-Method-Override", "PATCH");

或者

只需复制并粘贴此代码

public static JSONObject makeRequestCheck(String hostname, String token,String proId,String taskGrpId, String taskId) throws Exception {

    SSLSocketFactory sslFactory = new SimpleSSLSocketFactory(null);
    sslFactory
            .setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
    HttpParams params = new BasicHttpParams();
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory
            .getSocketFactory(), 80));
    registry.register(new Scheme("https", sslFactory, 443));
    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params,
            registry);
    HttpClient client = new DefaultHttpClient(ccm, params);
    String hostnamee = hostname+"projects/"+proId+"/taskgroups/"+taskGrpId+"/tasks/"+taskId+"/complete";
    HttpPost httpost = new HttpPost(hostnamee);
    System.out.println(hostnamee);
//  StringEntity se = new StringEntity(jsonSignin.toString());

    HttpResponse response = null;
    try {
    //  httpost.setEntity(se);
        httpost.setHeader("X-HTTP-Method-Override", "PATCH");
        httpost.setHeader("Content-type", "application/json");
        httpost.setHeader("Accept", "*/*");
        httpost.setHeader("Accept-Encoding", "gzip, deflate");
        httpost.addHeader("Connection", "keep-alive");
        httpost.addHeader("Accept-Language", "en-GB,en-US;q=0.8,en;q=0.6");
        httpost.setHeader("User-Agent", "nnst");
        httpost.setHeader("Accept-Charset", "utf-8");
        if (token == "NV") {
        } else {
            httpost.setHeader("Authorization", "Token" + " " + token);
        }
        response = client.execute(httpost);

    } catch (Exception e) {
        System.out.println("::my Exception ::" + e);
    }
    if (response == null) {
        System.out.println("no data");
    }
    String output = EntityUtils.toString(response.getEntity());

    JSONObject jobj = new JSONObject(output);

    return jobj;
}
