在 Java 中使用 atlassian 的 REST API 创建 Jira 问题时解析 Json 对象节点时出错

Question

我正在尝试在 java 中使用 Jira REST API 创建问题。但是我的控制台出现运行时异常。

Exception in thread "main" java.lang.RuntimeException: com.fasterxml.jackson.databind.JsonMappingException: Unexpected IOException (of type org.codehaus.jackson.JsonParseException): Illegal white space character (code 0x20) as character #3 of 4-char base64 unit: can only used between units
 at [Source: N/A; line: -1, column: -1]
    at CreateIssue.writeValue(CreateIssue.java:60)
    at com.mashape.unirest.request.HttpRequestWithBody.body(HttpRequestWithBody.java:158)
    at CreateIssue.main(CreateIssue.java:72)

下面是我的代码，我已经实现了与文档中提供的代码相同的代码，但仍然出现错误。

import com.fasterxml.jackson.core.JsonProcessingException;
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;
import com.mashape.unirest.http.ObjectMapper;
import org.codehaus.jackson.node.JsonNodeFactory;
import org.codehaus.jackson.node.ObjectNode;

import java.io.IOException;

public class CreateIssue{
    public static void main(String[]args) {
        JsonNodeFactory jnf = JsonNodeFactory.instance;
        ObjectNode payload = jnf.objectNode();

        {
            ObjectNode fields = payload.putObject("fields");
            {
                fields.put("summary", "This is test Summary");
                ObjectNode project = fields.putObject("project");
                {
                    project.put("key", "DEM12");
                }
                ObjectNode issueType = fields.putObject("issuetype");
                {
                    issueType.put("name", "Task");
                }
            }

        }
        // Connect Jackson ObjectMapper to Unirest
        Unirest.setObjectMapper(new ObjectMapper() {
            private com.fasterxml.jackson.databind.ObjectMapper jacksonObjectMapper
                    = new com.fasterxml.jackson.databind.ObjectMapper();

            public <T> T readValue(String value, Class<T> valueType) {
                try {
                    return jacksonObjectMapper.readValue(value, valueType);
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            }

            public String writeValue(Object value) {
                try {
                    return jacksonObjectMapper.writeValueAsString(value);
                } catch (JsonProcessingException e) {
                    throw new RuntimeException(e);
                }
            }
        });

        System.out.println("Payload from here: "+ payload);

        HttpResponse<com.mashape.unirest.http.JsonNode> response = null;
        try {
            response = Unirest.post("https://{myaccount}.atlassian.net//rest/api/3/issue")
                        .basicAuth("{myEmailId}", "{MyAPITOken}")
                    .header("Accept", "application/json")
                    .body(payload)
                    .asJson();


            System.out.println(response.getBody());
            System.out.println(response.getStatus());
        } catch (UnirestException e) {
            e.printStackTrace();
        }
    }
}

我在这里打印的输出是真实的 json，如果我使用该输出将 post 请求放入 Postman，它是 工作正常。所以我认为 错误在我的代码中某处 ，但我不知道在哪里。 有人可以帮忙吗？

Answer 1

// Connect Jackson ObjectMapper to Unirest
//Remove This Block Of Code first.
        Unirest.setObjectMapper(new ObjectMapper() {
            private com.fasterxml.jackson.databind.ObjectMapper jacksonObjectMapper
                    = new com.fasterxml.jackson.databind.ObjectMapper();

            public <T> T readValue(String value, Class<T> valueType) {
                try {
                    return jacksonObjectMapper.readValue(value, valueType);
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            }

            public String writeValue(Object value) {
                try {
                    return jacksonObjectMapper.writeValueAsString(value);
                } catch (JsonProcessingException e) {
                    throw new RuntimeException(e);
                }
            }
        });

//Then Add This Code.
//Use ObjectNode

ObjectNode obj = payload;
JSONObject json = new JSONObject(obj.toString());

HttpResponse<com.mashape.unirest.http.JsonNode> response = null;
        try {
            response = Unirest.post("https://{myaccount}.atlassian.net//rest/api/3/issue")
                        .basicAuth("{myEmailId}", "{MyAPITOken}")
                    .header("Accept", "application/json")
                    .body(json)
                    .asJson();


            System.out.println(response.getBody());
            System.out.println(response.getStatus());
        } catch (UnirestException e) {
            e.printStackTrace();
        }

I think so it will work.
