【二、http】go的http基本请求设置（设置查询参数、定制请求头）get和post类似

一、设置url后边的参数，（get和post请求为例子）

func requstByParamsGet(){requst, err := http.NewRequest(http.MethodGet, "http://httpbin.org/get", nil)if err != nil {fmt.Println("ss")}params := make(url.Values)params.Add("name", "kaiyue")params.Add("age", "18")//encode之后会生成如下，name=kaiyue&age=18requst.URL.RawQuery = params.Encode()r, err := http.DefaultClient.Do(requst)if err != nil {fmt.Println("ss")}defer r.Body.Close()printBody(r)
}func requstByParamsPost(){requst, err := http.NewRequest(http.MethodPost, "http://httpbin.org/post", nil)if err != nil {fmt.Println("ss")}params := make(url.Values)params.Add("name", "kaiyue")params.Add("age", "18")//encode之后会生成如下，name=kaiyue&age=18, 是组成url问号后边的参数requst.URL.RawQuery = params.Encode()r, err := http.DefaultClient.Do(requst)if err != nil {fmt.Println("ss")}defer r.Body.Close()printBody(r)
}
func main() {requstByParamsPost()
}

结果：

{"args": {"age": "18", "name": "kaiyue"}, "data": "", "files": {}, "form": {}, "headers": {"Accept-Encoding": "gzip", "Content-Length": "0", "Host": "httpbin.org", "User-Agent": "Go-http-client/1.1", "X-Amzn-Trace-Id": "Root=1-6544e26c-2a47c0392e3351a71259c068"}, "json": null, "origin": "120.244.60.192", "url": "http://httpbin.org/post?age=18&name=kaiyue"
}

二、定制http头中的参数

func requstByHeader(){requst, err := http.NewRequest(http.MethodGet, "http://httpbin.org/get", nil)if err != nil {fmt.Println("ss")}requst.Header.Add("user-agent", "chrome")r, err := http.DefaultClient.Do(requst)if err != nil {fmt.Println("ss")}defer r.Body.Close()printBody(r)
}func main() {requstByHeader()
}

结果：

{"args": {}, "headers": {"Accept-Encoding": "gzip", "Host": "httpbin.org", "User-Agent": "chrome", "X-Amzn-Trace-Id": "Root=1-6544e394-14143f26584a7eed32728fd7"}, "origin": "120.244.60.192", "url": "http://httpbin.org/get"
}
