Getting Go's HTTP post to emulate curl -d
问题
我正在尝试通过Go将内容发布到一个nginx服务器。我已经验证过，我可以通过curl正确地发布这个内容，具体使用以下命令：
$ curl http://example.com/myendpoint -d "Some Text"
我能够看到这个POST请求，并且正确地处理它。然而，当我尝试使用Go进行POST请求时，服务器会拒绝它。在nginx的访问日志中，我看到了以下两行：
127.0.0.1 - - [30/Jan/2014:05:57:34 +0000] "POST /myendpoint HTTP/1.1" 400 0 "-" "Go 1.1 package http"
127.0.0.1 - - [30/Jan/2014:05:57:39 +0000] "Some Text" 400 172 "-" "-"
我尝试的代码如下：
r, err := http.Post(uri, "application/x-www-form-urlencoded", bytes.NewReader(data))
if err != nil {
log.Printf("HTTP NOTIFICATION ERROR: %s\n", err)
return
}
r.Body.Close()
我做错了什么吗？谢谢！

I am attempting to post content to an nginx server through Go. I have verified that I am able to correctly POST this content through curl, specifically using this command:
$ curl http://example.com/myendpoint -d "Some Text"
I am able to see this POST, and process it correctly. However, when I try to perform a POST with Go, it is rejected by the server. In the nginx access logs, I see these two lines:
127.0.0.1 - - [30/Jan/2014:05:57:34 +0000] "POST /myendpoint HTTP/1.1" 400 0 "-" "Go 1.1 package http"
127.0.0.1 - - [30/Jan/2014:05:57:39 +0000] "Some Text" 400 172 "-" "-"
The code that I have tried is below:
<!-- language: go -->
r, err := http.Post(uri, "application/x-www-form-urlencoded", bytes.NewReader(data))
if err != nil {
log.Printf("HTTP NOTIFICATION ERROR: %s\n", err)
return
}
r.Body.Close()
Is there something that I am doing wrong? Thanks!

我无法看到你提供的代码片段中的任何特定问题，但是你可能没有按照application/x-www-form-urlencoded规范要求对数据进行编码。
尝试使用PostForm，它会代表你执行这个操作：
import (
"net/url"
)
// ...
r, err := http.PostForm(uri, url.Values{"key": {"Value"}, "id": {"123"}})
英文:
I can't see any particular issue with the code snippets you provided, but you may not be encoding the data as required by application/x-www-form-urlencoded's specification.
Try using PostForm instead, which will perform this on your behalf:
import (
"net/url"
)
// ...
r, err := http.PostForm(uri, url.Values{"key": {"Value"}, "id": {"123"}})

如果你更方便将你的帖子数据转换为[]byte而不是url.Values，你可以使用http.Client。下面的代码展示了如何使用Client来处理一个新的http请求。
var client http.Client
req, err := http.NewRequest("POST", myURL, data) // data的类型是[]byte
if err != nil {
// todo: 做一些处理
}
req.Header.Add("Content-Type", "application/x-www-form-urlencoded")
resp, err := client.Do(req)
if err != nil {
// todo: 做一些处理
}
defer resp.Body.Close()
// 处理你的响应。
希望对你有帮助！
英文:
If it is more convenient for you to convert your post data to []byte, vs url.Values, you can use http.Client. The code below shows how you can use the Client to process a new http request.
var client http.Client
req, err := http.NewRequest("POST", myURL, data) // data is of type []byte
if err != nil {
// todo: do something
}
req.Header.Add("Content-Type", "application/x-www-form-urlencoded")
resp, err := client.Do(req)
if err != nil {
// todo: do something
}
defer resp.Body.Close()
// process your response.
