我尝试与Apiary合作,制作了一个通用模板,将JSON发送到模拟服务器,并有以下代码:
package main
import (
"encoding/json"
"fmt"
"github.com/jmcvetta/napping"
"log"
"net/http"
)
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
s := napping.Session{}
h := &http.Header{}
h.Set("X-Custom-Header", "myvalue")
s.Header = h
var jsonStr = []byte(`
{
"title": "Buy cheese and bread for breakfast."
}`)
var data map[string]json.RawMessage
err := json.Unmarshal(jsonStr, &data)
if err != nil {
fmt.Println(err)
}
resp, err := s.Post(url, &data, nil, nil)
if err != nil {
log.Fatal(err)
}
fmt.Println("response Status:", resp.Status())
fmt.Println("response Headers:", resp.HttpResponse().Header)
fmt.Println("response Body:", resp.RawText())
}
这段代码没有正确地发送JSON,但我不知道为什么。JSON字符串在每次调用中都可以不同。我不能用Struct来做这个。
如果你已经有一个结构体。
import (
"bytes"
"encoding/json"
"io"
"net/http"
"os"
)
// .....
type Student struct {
Name string `json:"name"`
Address string `json:"address"`
}
// .....
body := &Student{
Name: "abc",
Address: "xyz",
}
payloadBuf := new(bytes.Buffer)
json.NewEncoder(payloadBuf).Encode(body)
req, _ := http.NewRequest("POST", url, payloadBuf)
client := &http.Client{}
res, e := client.Do(req)
if e != nil {
return e
}
defer res.Body.Close()
fmt.Println("response Status:", res.Status)
// Print the body to the stdout
io.Copy(os.Stdout, res.Body)
完整的依据。
我不熟悉午睡,但使用Golang的net/http包工作得很好(playground):
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
req.Header.Set("X-Custom-Header", "myvalue")
req.Header.Set("Content-Type", "application/json")
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()
fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
body, _ := ioutil.ReadAll(resp.Body)
fmt.Println("response Body:", string(body))
}
如果你已经有一个结构体。
import (
"bytes"
"encoding/json"
"io"
"net/http"
"os"
)
// .....
type Student struct {
Name string `json:"name"`
Address string `json:"address"`
}
// .....
body := &Student{
Name: "abc",
Address: "xyz",
}
payloadBuf := new(bytes.Buffer)
json.NewEncoder(payloadBuf).Encode(body)
req, _ := http.NewRequest("POST", url, payloadBuf)
client := &http.Client{}
res, e := client.Do(req)
if e != nil {
return e
}
defer res.Body.Close()
fmt.Println("response Status:", res.Status)
// Print the body to the stdout
io.Copy(os.Stdout, res.Body)
完整的依据。
除了标准的net/http包,你可以考虑使用我的GoRequest,它包装了net/http,让你的生活更容易,而不用考虑太多json或struct。但是您也可以在一个请求中混合和匹配它们!(你可以在gorequest github页面上看到更多细节)
所以,在最后你的代码会像下面这样:
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
request := gorequest.New()
titleList := []string{"title1", "title2", "title3"}
for _, title := range titleList {
resp, body, errs := request.Post(url).
Set("X-Custom-Header", "myvalue").
Send(`{"title":"` + title + `"}`).
End()
if errs != nil {
fmt.Println(errs)
os.Exit(1)
}
fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
fmt.Println("response Body:", body)
}
}
这取决于你想如何实现。我做这个库是因为我有同样的问题,我想要的代码更短,易于使用json,更易于维护在我的代码库和生产系统。
