带有效负载的Jsoup HTTP POST

Question

我试图通过Jsoup发出这个http请求:http://api.decarta.com/v1/[KEY]/batch?requestType=geocode如此处所示.这是我的相同代码:

                String postUrl=postURLPrefix+apiKey+"/batch?requestType=geocode";
                System.out.println(postUrl);
                String response= Jsoup.connect(postUrl).timeout(60000).ignoreContentType(true)
                        .header("Content-Type", "application/json;charset=UTF-8")
                        .method(Connection.Method.POST)
                        .data("payload",jsonPayload.toString())
                        .execute()
                        .body();

jsonPayload.toString()给出了:

{"payload":["146 Adkins Street,Pretoria,Pretoria,Gauteng","484 Hilda Street,Pretoria,Pretoria,Gauteng","268 Von Willich Street,Centurion,Centurion,Gauteng","100 Lion Road,Pretoria,Pretoria,Gauteng","Poligoon Street,Pretoria,Pretoria,Gauteng","91 Hornbill Street,Pretoria,Pretoria,Gauteng","55 Eland Street,Pretoria,Pretoria,Gauteng","31 Pelican Avenue,Centurion,Centurion,Gauteng","308 The Hillside Street,Pretoria,Pretoria,Gauteng","8 Spekhout Avenue,Centurion,Centurion,Gauteng","108 Apiesdoring Street,Pretoria,Pretoria,Gauteng","521 Louis Trichardt Street,Pretoria,Pretoria,Gauteng","31 Leopard Road,Pretoria,Pretoria,Gauteng","648 Klippan Street,Pretoria,Pretoria,Gauteng","13 Sweetpea Avenue,Pretoria,Pretoria,Gauteng","232 Kemphaan Street,Centurion,Centurion,Gauteng","32 Cantonments Road,Centurion,Centurion,Gauteng","882 Burlington St,Roseville,Gauteng","15 Brits Street,Olympus Ridge Complex,Centurion,Gauteng","15 Brits Street,Monument Park,Centurion,Gauteng","35 De La Rey Road,Monument Park,Centurion,Gauteng","112 Diamond St,Monument Park,Klerksoord,Gauteng","Hendrik Verwoerd Drive,Lyttelton,Centurion,Gauteng","777 Gambry Avenue,Garsfontein,Pretoria,Gauteng","57 Pheasant Avenue,Waterkloof Rand Corporatepark,Akasia,Gauteng","18 Huilboom Street,Manitoba Mews,Pretoria,Gauteng","75 Gousblom Avenue,Euro Stadt,Pretoria,Gauteng","88 Cambridge Avenue,Garsfontein,Centurion,Gauteng","662 Pual Kruger Street,Olympus Ridge Complex,Pretoria,Gauteng","231 Charles Street,Hatfield,Pretoria,Gauteng","9 Kobus Street,Pretoria West,Centurion,Gauteng","96 Siersteen Road,Byron Place,Pretoria,Gauteng","262 Molopo Avenue,Montana Crossing,Pretoria,Gauteng","171 Sonja Street,Moreleta Park,Centurion,Gauteng","751 Lucas Meyer Street,Moreleta Park,Pretoria,Gauteng","499 Moot Street,Centurion Lifestyle Centre,Pretoria,Gauteng","4 Hofsanger Road,Villa Lanei,Centurion,Gauteng","51 Newark Street,Centurion,Gauteng","25 Anton Street,Lyttelton,Centurion,Gauteng","15 Brits Street,Garsfontein Ext 10,Centurion,Gauteng","172 Wildeamandel Street,La Motagne,Pretoria,Gauteng","15 Fillicia Street,Waterkloof,Pretoria,Gauteng","20 Slagveld Street,Centurion,Gauteng","678 Rankdoring Street,Waterkloof Glen,Pretoria,Gauteng","7 Hillips Street,Faerie Glen X 34,Pretoria,Gauteng","59 Malherbe Street,Willows,Pretoria,Gauteng","204 Festival Street, Unit 1\",Willows,Pretoria","310 Cliff Avenue,Manitoba Mews,Pretoria,Gauteng","294 Panorama Road,Hatfield,Centurion,Gauteng","79 Buitenkant Street,Opera Plaza,Pretoria,Gauteng"]}

这是一个完全有效的json.

但是,Jsoup每次都返回HTTP状态400(格式错误).因此,如果可能的话,如何使用Jsoup发送具有JSON有效负载的正确http POST.(请注意其有效负载而不是url中的普通key-val对).

Answer 1

使用最新的JSOUP库.

如果您使用的是maven,请将以下条目添加到pom.xml

<dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.10.2</version>
</dependency>

以下代码将解决您的问题.

String postUrl=postURLPrefix+apiKey+"/batch?requestType=geocode";
            System.out.println(postUrl);
            String response= Jsoup.connect(postUrl).timeout(60000).ignoreContentType(true)
                    .method(Connection.Method.POST)
                    .requestBody("payload",jsonPayload.toString())
                    .execute()
                    .body();

您需要的是发布raw data。该功能已实现，但尚未添加。检查此拉取请求https://github.com/jhy/jsoup/pull/318。您真的需要为此使用 jsoup 吗？我的意思是您可以使用HttpURLConnection（这是 jsoup 在下面使用的）来发出请求，然后将响应作为字符串传递给 jsoup。

这是从www.mkyong.com获取的示例HttpURLConnection（但经过简化并添加了 json/原始数据）

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;

public class Main {

    public static void main(String[] args) {

        try {

            String url = "http://www.google.com";

            URL obj = new URL(url);
            HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
            conn.setReadTimeout(5000);
            conn.addRequestProperty("Accept-Language", "en-US,en;q=0.8");
            conn.addRequestProperty("User-Agent", "Mozilla");
            conn.addRequestProperty("Referer", "google.com");

            conn.setDoOutput(true);

            OutputStreamWriter w = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");

            w.write("SOME_JSON_STRING_HERE");
            w.close();

            System.out.println("Request URL ... " + url);

            int status = conn.getResponseCode();

            System.out.println("Response Code ... " + status);

            BufferedReader in = new BufferedReader(new InputStreamReader(
                    conn.getInputStream()));
            String inputLine;
            StringBuffer html = new StringBuffer();

            while ((inputLine = in.readLine()) != null) {
                html.append(inputLine);
            }

            in.close();
            conn.disconnect();

            System.out.println("URL Content... \n" + html.toString());
            System.out.println("Done");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
