英文:
Go: Posting with Payload/Post Body
问题
尝试在Go中进行HTTP Post请求：
请求地址：apiUrl
请求体（期望为JSON字符串）：postBody
这是我得到的错误信息：
无法将postBodyJson（类型为[]byte）作为http.Post的参数类型io.Reader使用：[]byte类型没有实现io.Reader（缺少Read方法）
我做错了什么？
代码：
package mainimport ("encoding/json""fmt""net/http")func main() {var postBody = []string{"http://google.com","http://facebook.com","http://youtube.com","http://yahoo.com","http://twitter.com","http://live.com",}requestUrl := "http://lsapi.seomoz.com/linkscape/url-metrics"postBodyJson, _ := json.Marshal(postBody)resp, err := http.Post(requestUrl, "application/json", postBodyJson)fmt.Println(resp)}
英文:
Trying to accomplish a HTTP Post in Go:
Posting to: apiUrl
Payload/Post Body (expected as a json string): postBody
Here is the error I'm getting:
cannot use postBodyJson (type []byte) as type io.Reader in argument to http.Post:[]byte does not implement io.Reader (missing Read method)
What am I doing wrong?
Code:
package mainimport ("encoding/json""fmt""net/http")func main() {var postBody = []string{"http://google.com","http://facebook.com","http://youtube.com","http://yahoo.com","http://twitter.com","http://live.com",}requestUrl := "http://lsapi.seomoz.com/linkscape/url-metrics"postBodyJson, _ := json.Marshal(postBody)resp, err := http.Post(requestUrl, "application/json", postBodyJson)fmt.Println(resp)}

得分: 3
package mainimport ("bytes""encoding/json""fmt""log""net/http")func main() {var postBody = []string{"http://google.com","http://facebook.com","http://youtube.com","http://yahoo.com","http://twitter.com","http://live.com",}apiUrl := "http://lsapi.seomoz.com/linkscape/url-metrics"buf := bytes.NewBuffer(nil)enc := json.NewEncoder(buf)err := enc.Encode(postBody)if err != nil {log.Fatal(err)}resp, err := http.Post(apiUrl, "application/json", buf)if err != nil {log.Fatal(err)}fmt.Println(resp)}
类似这样的代码可能会起作用。但正如我在评论中已经提到的，你应该更加熟悉这门语言。在发布代码时，请确保它可以编译。
英文:
package mainimport ("bytes""encoding/json""fmt""log""net/http")func main() {var postBody = []string{"http://google.com","http://facebook.com","http://youtube.com","http://yahoo.com","http://twitter.com","http://live.com",}apiUrl := "http://lsapi.seomoz.com/linkscape/url-metrics"buf := bytes.NewBuffer(nil)enc := json.NewEncoder(buf)err := enc.Encode(postBody)if err != nil {log.Fatal(err)}resp, err := http.Post(apiUrl, "application/json", buf)if err != nil {log.Fatal(err)}fmt.Println(resp)}
Something like this might work. But as I already said in the comments, you should familiarize yourself with the language a little more. When you post code, make sure it compiles.
