.NET HttpClient和webapi相关的东东先记录一点。传递Authorization header,token
分类:
.NET
get请求传递Authorization header,token
string url = "你请求的url";
string token = "your token";
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("Authorization", $"Bearer {token}");
string result = client.GetAsync(url).Result.Content.ReadAsStringAsync().Result;Post,FormUrlEncodedContent传递参数
public static void Main()
{
HttpClient client = new HttpClient();
List<KeyValuePair<string, string>> kvlist = new List<KeyValuePair<string, string>>();
kvlist.Add(new KeyValuePair<string, string>("aa", "a"));
kvlist.Add(new KeyValuePair<string, string>("bb", "x"));
HttpContent content = new FormUrlEncodedContent(kvlist);
string result = client.PostAsync("http://localhost:8099/api/xx", content).Result.Content.ReadAsStringAsync().Result;
}Post,StringContent传递参数：
public static void Main()
{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent strcontent = new StringContent(JsonConvert.SerializeObject(new { aa = "a", bb = "x" }), Encoding.UTF8, "application/json");
string result = client.PostAsync("http://localhost:8099/api/xx", strcontent).Result.Content.ReadAsStringAsync().Result;
Console.ReadLine();
}
Post,StringContent传递参数,Json参数，传递header,token
和上面那个其实是一样的，就多传递了一个token
public void SendMail()
{
string token = "你的token";
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("Authorization", $"Bearer {token}");
var content = new
{
fromPerson = "发件人",
mailTitle = "标题",
mailBody = "正文内容",
recipientArry = new List<string>() { "收件人1@qq.com", "收件人2@qq.com" },
};
StringContent strcontent = new StringContent(JsonConvert.SerializeObject(content), Encoding.UTF8, "application/json");
string result = client.PostAsync("http://localhost:59154/api/SendMail", strcontent).Result.Content.ReadAsStringAsync().Result;
}
简单封装一下，带token的get与post请求
代码如下：
public class RequestTools
{
/// <summary>
/// 封装通用的get请求
/// </summary>
/// <param name="baseAddress"></param>
/// <param name="token"></param>
/// <param name="url"></param>
/// <returns></returns>
public string Get(string baseAddress, string token, string url)
{
string questUrl = baseAddress + url;
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("Authorization", $"Bearer {token}");
string result = client.GetAsync(questUrl).Result.Content.ReadAsStringAsync().Result;
return result;
}
/// <summary>
/// 封装通用的Post请求
/// </summary>
/// <param name="baseAddress"></param>
/// <param name="token"></param>
/// <param name="url"></param>
/// <param name="data"></param>
/// <returns></returns>
public string Post(string baseAddress, string token, string url,object data)
{
string questUrl = baseAddress + url;
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("Authorization", $"Bearer {token}");
StringContent strcontent = new StringContent(JsonConvert.SerializeObject(data), Encoding.UTF8, "application/json");
string result = client.PostAsync(questUrl, strcontent).Result.Content.ReadAsStringAsync().Result;
return result;
}
}使用封装get请求：
public override async Task OnStart(JobContext jobContext)
{
// 从配置文件获取请求接口的基础地址
string baseAddress = SmartEDU.Utils.Appsettings.Configuration["ApiVisit:Address"];
// 获取token
TokenTools tokenTools = new TokenTools();
string token = await tokenTools.GetToken(jobContext);
// 通过工具类调用接口，并拿到返回数据后反序列化解析成需要的类
RequestTools requestTools = new RequestTools();
// 如果是本地接口的测试可以把baseAddress换成本地地址即可，比如："http://localhost:8805"
string prodResult = requestTools.Get(baseAddress, token, "/prodedu/api/Report/GetYesterdayProjectAbnormal");
BaseApiWrapDto<ProjectExamineDto> projectExamineDto = JsonConvert.DeserializeObject<BaseApiWrapDto<ProjectExamineDto>>(prodResult);
}使用封装的post请求：
public override async Task OnStart(JobContext jobContext)
{
// 从配置文件获取请求接口的基础地址,一般都是配置域名或者内部ip等
string baseAddress = SmartEDU.Utils.Appsettings.Configuration["ApiVisit:Address"];
// 获取token
TokenTools tokenTools = new TokenTools();
string token = await tokenTools.GetToken(jobContext);
// 通过工具类调用接口
RequestTools requestTools = new RequestTools();
// 构建好接口需要的参数
var data = new
{
stdetailID = "3d6717e7300246249c260d18cc9b0279",
PageIndex = 1,
PageSize = 999,
Orders = new List<object>() {
new { OrderField = "teacherNames", IsDesc=true }
},
};
string prodResult = requestTools.Post(baseAddress, token, "/labroom/api/Report/GetSchoolClassOrCourseDataGather", data);
}post请求接收方的方法定义(这里的测试接口没有使用标准的restful定义，用restful标准定义的接口一样的不影响)：
[HttpPost]
public ObjectResult GetSchoolClassOrCourseDataGather([FromBody] QuerSchoolLabDTO query)
{
//换成AJ封装的方法
return Success(rs.GetSchoolTeacherDataGather(query));
}接收实体QuerSchoolLabDTO的定义：
public class QuerSchoolLabDTO: QueryBase
{
public string stdetailID { get; set; }
/// <summary>
/// 0：课程数据，1：班级数据
/// </summary>
public int dataType { get; set; }
/// <summary>
/// 多字段排序
/// </summary>
public List<OrderInfo> orders { get; set; }
}
/// <summary>
/// 排序字段
/// </summary>
public class OrderInfo
{
/// <summary>
/// 排序字段
/// </summary>
public string OrderField { get; set; }
/// <summary>
/// 是否为降序
/// </summary>
public Boolean IsDesc { get; set; }
}
webapi中这样写可以接收到httpclient传递的参数
JObject是Newtonsoft.Json.Linq下面的。当然这种传递参数的写法，使用对象接收也是能接收到的比如：[FromBody] Mail mails
设置类型还可以直接点出来设置
strcontent.Headers.ContentType = new MediaTypeHeaderValue("application/json");
strcontent.Headers.ContentType.CharSet = "utf-8";HttpClient手动传递cookie信息
//获取cookie的token信息
string token;
HttpContext.Request.Cookies.TryGetValue("token", out token);
//发送请求携带token
HttpClient httpClient = new HttpClient();
var message = new HttpRequestMessage(HttpMethod.Post, "http://localhost:X5J/api/v1/Token");
message.Headers.Add("Cookie", "token=" + token);
var httpResponseHeaders = httpClient.SendAsync(message).Result;如果是请求了一遍想要自带cookie的话可以这样做
HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent strcontent = new StringContent(JsonConvert.SerializeObject("aa"), Encoding.UTF8, "application/json");
var message = new HttpRequestMessage(HttpMethod.Post, "your address");
//设置cookie信息
message.Headers.Add("Cookie", "token=" + token);
//设置contetn
message.Content = strcontent;
//发送请求
var httpResponseHeaders = httpClient.SendAsync(message).Result;一个简单的get请求示例
/// <summary>
/// HttpClient实现Get请求
/// </summary>
static async void dooGet()
{
string url = "http://localhost:52824/api/register?id=1&leval=5";
//创建HttpClient（注意传入HttpClientHandler）
var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };
using (var http = new HttpClient(handler))
{
//await异步等待回应
var response = await http.GetAsync(url);
//确保HTTP成功状态值
response.EnsureSuccessStatusCode();
//await异步读取最后的JSON（注意此时gzip已经被自动解压缩了，因为上面的AutomaticDecompression = DecompressionMethods.GZip）
Console.WriteLine(await response.Content.ReadAsStringAsync());
}
}传递参数的同时传递一个cookie

c# HttpClient 给webapi post传递一个参数
