我編寫(xiě)了一個(gè) go 程序來(lái)查詢(xún) github 存儲(chǔ)庫(kù)“golang:go”中的問(wèn)題。http.Get() 以狀態(tài)“200 OK”響應(yīng)。然后我查詢(xún)最近 3 個(gè)月內(nèi)創(chuàng)建的問(wèn)題，http.Get() 返回“422 Unprocessable Entity”。下面是程序import( "fmt" "time" "net/http" "net/url" )func main() { var ret error var str string q:=url.QueryEscape("repo:golang/go") fmt.Println("q:", q) urlStr := "https://api.github.com/search/issues" +"?q=" + q fmt.Println("urlStr:", urlStr) resp, ret:= http.Get(urlStr) fmt.Println("ret :", ret, "resp.status :", resp.Status) timeStr := "created:" to := time.Now() from := to.AddDate(0, -3, 0) str = to.Format("2006-01-02") timeStr = timeStr + str + ".." fmt.Printf("time1 : %s\n", timeStr) str = from.Format("2006-01-02") timeStr = timeStr + str fmt.Printf("time2 : %s\n", timeStr) q=url.QueryEscape("repo:golang/go" + timeStr) fmt.Println("q:", q) urlStr = "https://api.github.com/search/issues" +"?q=" + q fmt.Println("urlStr:", urlStr) resp, ret = http.Get(urlStr) fmt.Println("ret :", ret, "resp.status :", resp.Status) } 我用它來(lái)形成查詢(xún)。我是網(wǎng)絡(luò)編程的新手，無(wú)法理解我在形成第二個(gè)查詢(xún)時(shí)出錯(cuò)的地方。

對(duì)我有用的兩件事
1）反轉(zhuǎn)你的timeStr中的“from”和“to”
2）不要在timeStr上使用QueryEscape，只需像這樣添加它
???urlStr?=?"https://api.github.com/search/issues"?+?"?q=repo:golang/go+"?+?timeStr
不要使用符號(hào)（我最初用這個(gè)回答）使用加號(hào)或空格。
呼喚遠(yuǎn)方

我像下面這樣使用，如果我不轉(zhuǎn)義第二個(gè)網(wǎng)址，它對(duì)我有用：
package main
import(
"fmt"
"time"
"net/http"
"net/url"
)
func main() {
var ret error
var str string
q:=url.QueryEscape("repo:golang/go")
fmt.Println("q:", q)
urlStr := "https://api.github.com/search/issues" +"?q=" + q
fmt.Println("urlStr:", urlStr)
resp, ret:= http.Get(urlStr)
fmt.Println("ret :", ret, "resp.status :", resp.Status)
timeStr := "created:"
to := time.Now()
from := to.AddDate(0, -3, 0)
str = to.Format("2006-01-02")
timeStr = timeStr + str + ".."
fmt.Printf("time1 : %s\n", timeStr)
str = from.Format("2006-01-02")
timeStr = timeStr + str
fmt.Printf("time2 : %s\n", timeStr)
urlStr = "https://api.github.com/search/issues" +"?q=" + "repo:golang/go&created:2018-11-29..2018-08-29"
fmt.Println("urlStr:", urlStr)
resp, ret = http.Get(urlStr)
fmt.Println("ret :", ret, "resp.status :", resp.Status)
}
輸出是：
q: repo%3Agolang%2Fgo
urlStr: https://api.github.com/search/issues?q=repo%3Agolang%2Fgo
ret : <nil> resp.status : 200 OK
time1 : created:2018-11-29..
time2 : created:2018-11-29..2018-08-29
urlStr: https://api.github.com/search/issues?q=repo:golang/go&created:2018-11-29..2018-08-29
ret : <nil> resp.status : 200 OK

當(dāng)客戶(hù)端發(fā)送無(wú)效輸入時(shí)，包括來(lái)自github 的API 在內(nèi)的許多 API都會(huì)返回狀態(tài)代碼。422在您的代碼中，錯(cuò)誤的輸入是由連接兩個(gè)沒(méi)有“分隔符”的限定符的行生成的。
因此，這"repo:golang/go" + timeStr將導(dǎo)致q包含單個(gè)“合并”限定符的值看起來(lái)像這樣：
"repo:golang/gocreated:2018-1...
要修復(fù)您的代碼，您只需在兩個(gè)限定符之間添加一個(gè)空格，您的查詢(xún)就可以正常工作。
