Httpclient HttplientDelete传递JSON参数 总结

HttpPost、HttpPut继承了HttpEntityEnclosingRequestbase类，所以有setEntity方法。

一般的 DELETE 请求参数是置于路径中的，所以一般的 httpDelete 不会像 httpPost 一样使用如下方式传递 JSON参数

HttpPost httpPost = new HttpPost(actionUrl);

StringEntity entity = new StringEntity(jsonBody, ContentType.APPLICATION_JSON);
httpPost.setEntity(entity);

response = httpClient.execute(httpPost);

为了使用和 post put 类似的方式，这里我们自己定义一个 httpDelete 但也继承 HttpEntityEnclosingRequestbase 从而获得 setEntity 的方法；

类如下定义，几乎是 直接复制 httppost 的继承方式；

import org.apache.http.annotation.NotThreadSafe;
import org.apache.http.client.methods.HttpEntityEnclosingRequestbase;
import java.net.URI;


@NotThreadSafe
public class HttpDeleteWithBody extends HttpEntityEnclosingRequestbase {

    public static final String METHOD_NAME = "DELETE";

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

    public HttpDeleteWithBody(final String uri) {
        super();
        setURI(URI.create(uri));
    }

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

    public HttpDeleteWithBody() {
        super();
    }
}

然后在原有代码替换 httppost 即可 一般的post使用方法见最上面问题的示例代码

我们定义后的 httpdelete 替换如下：

// 上面自定义的类
HttpDeleteWithBody httpDelete = new HttpDeleteWithBody(actionUrl);

StringEntity entity = new StringEntity(jsonBody, ContentType.APPLICATION_JSON);
httpDelete.setEntity(entity);

response = httpClient.execute(httpDelete);

直接替换后即可使用
