我正在尝试通过 POST 发送以下数据对 API 的 HTTP 请求:
{
"client_interface":{
"source_address":source,
"destination_address":destn,
"message":encrypted_msg,
"business_event_url":settings.Message_CallbackURL
},
"server_interface":{
"message_id":msg_id
}
}
API 响应以下错误:
{
"Meta":{
"Requestid":12301343169471000
},
"Error":{
"Message":"Request body contains badly-formed JSON (at position 51)",
"Param":""
}
}
代码:
apiUrl := "http://example.com"
tr := &http.Transport{
TLSClientConfig: &tls.Config{InsecureSkipVerify : true},
}
jsonStr := []byte(`{
"client_interface": {
"source_address": source,
"destination_address": destn,
"message": encrypted_msg,
"business_event_url": settings.Message_CallbackURL
},
"server_interface": {
"message_id": msg_id
}
}`)
req, err := http.NewRequest("POST", apiUrl, bytes.NewBuffer(jsonStr))
fmt.Println("req..........",req)
if err!=nil{
log.Println("err in http req..............",err)
}
req.Header.Set("Content-Type", "application/json")
req.Header.Set("requestid", msg_id)
req.Header.Set("Authorization", "Bearer "+conn_token)
client := &http.Client{Transport: tr}
resp, err := client.Do(req)
if resp!=nil{
body, _ := ioutil.ReadAll(resp.Body)
}

最佳答案
首先:请使用gofmt
您的第一个代码无法工作，因为 golang 不会替换字符串中的变量。最好使用结构。
使用结构它不起作用，因为您从小写字母命名结构字段，这意味着 go 中的“私有(private)”字段。所以encoding/json包无法访问它们，只是跳过它们。使用大写首字母。
另一个修复是关于 'json:"tag"' - 这里的标签表示编码的字段名称，而不是类型。所以而不是'json:"string"'你应该使用 'json:"message_id"'或者。您可以像这样指定类型 'json:"field_name,type"'或像这样 'json:",type"'但是 encoding/json自己猜类型。
(由于 Markdown ，我在标签中使用了错误的引号)
我用了netcat -l 5000监听 localhost 上的 5000 端口并将所有内容打印到终端。然后我改了url至http://localhost:5000 (不是 https)向自己发送请求。
需要重启netcat每次上类。
而且我使日志记录更具可读性。
这也是 Go 中的 CamelCase 命名约定。
稍微改变了你的代码
