将 JSON 对象插入 JSOUP 时出错

Question

我正在尝试使用 JSOUP post 一些 json 对象到 Saiku Server 中。这是我的代码。

Response document1 = Jsoup
         .connect(
           "http://localhost:8080/saiku/rest/saiku/admin/datasources/")
           .header("Content-Type", "application/json")
           .data(testJson.toJSONString())
     .ignoreContentType(true)
         .referrer("http://localhost:8080/")
         .cookie("JSESSIONID", res.cookie("JSESSIONID"))
          .userAgent(
           "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36")
         .method(Method.POST).timeout(10000).execute();

我收到类似

的错误

 Errorjava.lang.IllegalArgumentException: Must supply an even number of key value pairs .

我在很多网站上进行了搜索，但找不到解决方案。有人可以澄清我。提前致谢。我在这里附上我的代码，

Answer 1

根据 javadoc:

Connection data(String... keyvals)

Add a number of request data parameters. Multiple parameters may be set at once, e.g.: .data("name", "jsoup", "language", "Java", "language", "English"); creates a query string like: ?name=jsoup&language=Java&language=English

我认为你需要：

Connection requestBody(String body)

Set a POST (or PUT) request body. Useful when a server expects a plain request body, not a set for URL encoded form key/value pairs

Answer 2

我使用 requestBody() 发布 JSON object.The requestBody() 方法仅在 JSOUP 1.9.1 jar 中可用，我发布了下面的代码供您参考。

    // JSON Object
    JSONObject testJson = new JSONObject();

    testJson.put("connectionname", "drinkss");
    testJson.put("jdbcurl", "jdbc:mysql://localhost/drink");
    testJson.put("schema", "datasources/dr.xml");
    testJson.put("driver", "com.mysql.jdbc.Driver");
    testJson.put("username", "root");
    testJson.put("password", "211218");
    testJson.put("connectiontype", "MONDRIAN");

    // For Posting datasource into server
    Response document1 = Jsoup
            .connect(
                    "http://localhost:8080/saiku/rest/saiku/admin/datasources/")
            .header("Content-Type", "application/json")
            .requestBody(testJson.toString())
            .data(testJson)
            .ignoreContentType(true)
            .referrer("http://localhost:8080/")
            .cookie("JSESSIONID", res.cookie("JSESSIONID"))
            .userAgent(
                    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36")
            .method(Method.POST).timeout(10000).execute();
    System.out.println("post successfully....."
            + testJson.toJSONString());
