Watson对话框cURL对话后请求不传递表单数据 [英] Watson dialog cURL conversation post request not passing form data

问题描述

在进行后期cURL请求时，如下所示，尝试继续创建的会话watson，而不返回新会话。

  curl -uUSERNAME：PASSWORD-X POST --form conversation_id = CONVOID --form client_id = CLIENTID --form input =你有什么类型的浇头？ https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation
  

如果我使用下面的cURL它工作正常。

  curl -uUSERNAME：PASSWORD--dataconversation_id = CONVOID& client_id = CLIENTID& input =的浇头你有吗？ https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation 
  

我的问题是，现在当试图编写ac＃wrapper我运行在同一问题POST请求无法正确传输其表单数据。

发生了什么？

我需要一个c＃MVC等同于 - data 格式化。 （目前使用 HttpClient.PostAsync ），或者弄清楚使用发布请求继续会话的确是错误的。

至于我可以告诉我在c＃正确复制post请求，所以我不认为有两个问题。 （只有一个post请求问题，不是cURL问题，然后C＃实现问题。）

对于什么是值得我留下的格式我提交他们的命令，只有用BLOCKCAPITALS替换敏感值。如果它看起来像我错过了一个引号或大括号，这是因为我有和可能是问题的原因。

解决方案

服务需要一个应用程序/ x-www-form-urlencoded POST请求

要在 curl 中执行，您需要使用 -d 参数：

  curl -uUSERNAME：PASSWORD-X POST 
  - d conversation_id = CONVOID 
 -d client_id = CLIENTID 
 -d input =你有什么类型的浇头？ 
https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation
  

POST请求到HTTP服务器，与浏览器在用户填写HTML表单并按提交按钮时的方式相同。这将导致curl使用内容类型应用程序/ x-www-form-urlencoded将数据传递到服务器。与-F，--form比较。

Curl 文档

When making a post cURL request as below to try and continue a created conversation watson instead returns a new conversation.

curl -u "USERNAME":"PASSWORD" -X POST  --form conversation_id=CONVOID  --form client_id=CLIENTID  --form input="What type of toppings do you have?"  "https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation"

If i use the below cURL it works fine.

curl -u "USERNAME":"PASSWORD" --data "conversation_id=CONVOID&client_id=CLIENTID&input=What type of toppings do you have?" https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation

My issue being that now when trying to write a c# wrapper i'm running in to the same issue that POST requests fail to transmit their form data correctly.

What's going on ?

I either need a c# MVC equivalent to the "--data" formatting. ( currently using HttpClient.PostAsync) or to figure out what is exactly wrong with using post requests to continue conversations.

As far as i can tell i am replicating the post request in c# correctly so i don't think there are two issues. ( just one post request issue, not a cURL issue then a C# implementation issue.)

For what it's worth i have left the commands in the format i submitted them, only replacing sensitive values with BLOCKCAPITALS. If it looks like i've missed a quotation mark or curly bracket , it's because i have and may be the cause of the issue.

解决方案

The service expects an application/x-www-form-urlencoded POST request

To do that in curl you need to use the -d parameter:

curl -u "USERNAME":"PASSWORD" -X POST 
  -d conversation_id=CONVOID 
  -d client_id=CLIENTID
  -d input="What type of toppings do you have?"
  "https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation"

-d, --data

(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F, --form.
