面向对象的操作模式 ```go req := gotool.HttpUtils.NewRequest(). Debug(true). SetHeaders(map[string]string{ "Content-Type": "application/x-www-form-urlencoded", }).SetTimeout(5) resp, err := req.Get("http://127.0.0.1") resp,err := gotool.HttpUtils.NewRequest().Get("http://127.0.0.1") ``` ### GET #### 查询参数 ```go resp, err := req.Get("http://127.0.0.1:8000") resp, err := req.Get("http://127.0.0.1:8000",nil) resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest") resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", "address=beijing") OR resp, err := gotool.HttpUtils.Get("http://127.0.0.1:8000") resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000") ``` #### 多参数 ```go resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", map[string]interface{}{ "name": "jason", "score": 100, }) defer resp.Close() body, err := resp.Body() if err != nil { return } return string(body) ``` ### POST ```go // Send nil resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000") // Send integer resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", 100) // Send []byte resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", []byte("bytes data")) // Send io.Reader resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", bytes.NewReader(buf []byte)) resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", strings.NewReader("string data")) resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", bytes.NewBuffer(buf []byte)) // Send string resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", "title=github&type=1") // Send JSON resp, err := gotool.HttpUtils.JSON().Post("http://127.0.0.1:8000", "{\"id\":10,\"title\":\"HttpRequest\"}") // Send map[string]interface{}{} resp, err := req.Post("http://127.0.0.1:8000", map[string]interface{}{ "id": 10, "title": "HttpRequest", }) defer resp.Close() body, err := resp.Body() if err != nil { return } return string(body) resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000") resp, err := gotool.HttpUtils.JSON().Post("http://127.0.0.1:8000", map[string]interface{}{"title":"github"}) resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).JSON().Post("http://127.0.0.1:8000","{\"title\":\"github\"}") ``` ### 代理模式 ```go proxy, err := url.Parse("http://proxyip:proxyport") if err != nil { log.Println(err) } resp, err := gotool.HttpUtils.Proxy(http.ProxyURL(proxy)).Get("http://127.0.0.1:8000/ip") defer resp.Close() if err != nil { log.Println("Request error：%v", err.Error()) } body, err := resp.Body() if err != nil { log.Println("Get body error：%v", err.Error()) } log.Println(string(body)) ``` ### 上传文件 Params: url, filename, fileinput ```go resp, err := req.Upload("http://127.0.0.1:8000/upload", "/root/demo.txt", "uploadFile") body, err := resp.Body() defer resp.Close() if err != nil { return } return string(body) ``` ### 提示模式 #### 默认 false ```go req.Debug(true) ``` #### 以标准输出打印： ```go [HttpRequest] ------------------------------------------------------------------- Request: GET http: //127.0.0.1:8000?name=iceview&age=19&score=100 Headers: map[Content-Type:application/x-www-form-urlencoded] Cookies: map[] Timeout: 30s ReqBody: map[age:19 score:100] ------------------------------------------------------------------- ``` ## Json Post JSON 请求 #### 设置请求头 ```go req.SetHeaders(map[string]string{"Content-Type": "application/json"}) ``` Or ```go req.JSON().Post("http://127.0.0.1:8000", map[string]interface{}{ "id": 10, "title": "github", }) req.JSON().Post("http://127.0.0.1:8000", "{\"title\":\"github\",\"id\":10}") ``` #### Post 请求 ```go resp, err := req.Post("http://127.0.0.1:8000", map[string]interface{}{ "id": 10, "title": "HttpRequest", }) ``` #### 打印格式化的 JSON ```go str, err := resp.Export() if err != nil { return } ``` #### 解组 JSON ```go var u User err := resp.Json(&u) if err != nil { return err } var m map[string]interface{} err := resp.Json(&m) if err != nil { return err } ```
