Question

我正在尝试使用以下代码在我的jira中创建新的项目问题，

using using System.Text;
using System.Net.Http;
using System.Json;
using System.Web.Script.Serialization;

namespace Test
{
    class Class1
    {
        public void CreateIssue()
        {
            string message = "Hai \"!Hello\" ";
            string data = "{\"fields\":{\"project\":{\"key\":\"TP\"},\"summary\":\"" + message +    "\",\"issuetype\":{\"name\": \"Bug\"}}}";
            System.Net.Http.HttpClient client = new System.Net.Http.HttpClient();
            client.DefaultRequestHeaders.ExpectContinue = false;
            client.Timeout = TimeSpan.FromMinutes(90);
            byte[] crdential = UTF8Encoding.UTF8.GetBytes("adminName:adminPassword");
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(crdential));
            client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));     
            System.Net.Http.HttpContent content = new StringContent(data, Encoding.UTF8, "application/json");
            try
            {
                client.PostAsync("http://localhost:8080/rest/api/2/issue",content).ContinueWith(requesTask=>
                {
                    try
                    {
                        HttpResponseMessage response = requesTask.Result;
                        response.EnsureSuccessStatusCode();
                        response.Content.ReadAsStringAsync().ContinueWith(readTask =>
                        {
                            var out1 = readTask.Result;
                        });
                    }
                    catch (Exception exception)
                    {
                        Console.WriteLine(exception.StackTrace.ToString());
                        Console.ReadLine();
                    }
                });
            }
            catch (Exception exc)
            {
            }
        }
    }
}

它会抛出如下错误：

“{\”errorMessages \“：[\”意外字符（'！'（代码33））：期待逗号分隔OBJECT条目\ n在[来源：org.apache.catalina.connector.CoyoteInputStream@1ac4eeea ; line：1，column：52] \“]}”

但是我在Firefox Poster中使用相同的json文件，我已经创建了这个问题。

Json文件：{“fields”：{“project”：{“key”：“TP”}，“summary”：“Hai \”！Hello \“”，\“issuetype \”：{\“name \“：\”Bug \“}}}”

那么，我的代码出了什么问题？

Answer 1

转义引号似乎存在问题。

这是data变量初始化后的漂亮版本：

{
    "fields":{
        "project":{
            "key":"TP"
        },
        "summary":"Hai "!Hello" ",
        "issuetype":{
            "name": "Bug"
        }
    }
}

错误消息显示Unexpected character ('!')...was expecting comma...。查看漂亮打印的字符串，错误的原因变得清晰：

"summary":"Hai "!Hello" ",

JIRA使用的JSON解释器可能会解析此文本：

"summary":"Hai " ⇐ This trailing quotation mark ends the "summary" value
! ⇐ JSON expects a comma here
Hello" ",

在您的C＃代码中，您有：

string message = "Hai \"!Hello\" ";

感叹号前面的引号用反斜杠转义。但是，这只会转义C＃编译器的引号。当C＃编译器完成后，反斜杠就消失了。要在JSON字符串中嵌入引号，需要使用反斜杠后跟引号：

string message = "Hai \\\"!Hello\\\" ";

为了避免许多与JSON格式相关的陷阱，我强烈建议使用Microsoft's JavaScriptSerializer class。此类提供了一种安全，快速的方法来创建有效的JSON：

using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

namespace JsonTests
{
    class Program
    {
        static void Main(string[] args)
        {
            string message = "Hai \"!Hello\" ";

            var project = new Dictionary<string, object>();
            project.Add("key", "TP");

            var issuetype = new Dictionary<string, object>();
            issuetype.Add("name", "Bug");

            var fields = new Dictionary<string, object>();
            fields.Add("project", project);
            fields.Add("summary", message);
            fields.Add("issuetype", issuetype);

            var dict = new Dictionary<string, object>();
            dict.Add("fields", fields);

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            string json = serializer.Serialize((object)dict);
            Console.WriteLine(json);
        }
    }
}

结果：

{"fields":{"project":{"key":"TP"},"summary":"Hai \"!Hello\" ","issuetype":{"name":"Bug"}}}
