Google端点GET请求URL参数[Python] [英] Google Endpoints GET request URL parameters [Python]

问题描述

我目前正在一个小项目中，我需要编写一个GET处理程序.我正在使用端点文档中提供的Echo示例.

I am currently working on a small project where I need to write a GET handler. I am working from the Echo example provided in the endpoints documentation.

我有我的资源容器:

GET_EMAIL_RESOURCE = endpoints.ResourceContainer(
    message_types.VoidMessage,
    i = messages.IntegerField(1, default = 1)
)

我有我的处理程序:

@endpoints.method(
    GET_EMAIL_RESOURCE,
    EchoResponse,
    path='echo/getEmails/{i}',
    http_method='GET',
    name='echo_get_emails'
)
def echo_get_emails(self, request):
    if (request.i == 1):
        out = "default"
    else:
        out = "a"*request.i
    return EchoResponse(content=out)

要访问此文件，我正在使用curl:

And to access this I am using curl:

curl --request GET --header "Content-Type: application/json" http://localhost:8080/_ah/api/echo/v1/echo/getEmails/3

现在这可以正常工作并返回您期望的结果，但是如果我需要将更多信息编码到我的URL中，例如:

Now this works fine and returns what you expect, but if I need to encode more information into my URL such as:

getEmails/value1=someValue&value2=someOtherValue

我不知道该怎么做，也无法在文档中找到解释或示例.

I cannot figure out how to do this and I am unable to find an explanation or example in the docs.

任何帮助将不胜感激.

我的代码现在看起来像这样:

My code now looks like so:

# main.py

GET_EMAIL_RESOURCE = endpoints.ResourceContainer(
    message_types.VoidMessage,
    i = messages.IntegerField(1, default = 1)
)

@endpoints.method(
    GET_EMAIL_RESOURCE,
    EchoResponse,
    path='echo/getEmails',
    http_method='GET',
    name='echo_get_emails'
)
def echo_get_emails(self, request):
    out = str(request.trailingDigits) + " : " +str(request.leadingDigits)
    return EchoResponse(content = out)

，并且在我的openapi.json中，我具有以下路径:

and in my openapi.json under the path I have:

"/echo/v1/echo/getEmails" : {
  "get": {
    "operationId": "EchoApi_getEmails",
    "parameters" : [
      {
        "name": "trailingDigits",
        "in": "query",
        "description": "Trailing digits",
        "required": true,
        "type": "string"
      },
      {
        "name": "leadingDigits",
        "in": "query",
        "description": "Leading digits",
        "required": true,
        "type": "string"
      }
    ]
  }
}

但是我运行请求时curl --request GET --header"Content-Type:application/json" http://localhost:8080/_ah/api/echo/v1/echo/getEmails?trailingDigits = 2& leadingDigits = 2

Yet when I run the request curl --request GET --header "Content-Type: application/json" http://localhost:8080/_ah/api/echo/v1/echo/getEmails?trailingDigits=2&leadingDigits=2

我找回了TrailingDigits的内容，但是LeadingDigits的默认值

I get back the contents of trailingDigits but the default for leadingDigits

推荐答案

Google论坛中的此问题已为我解决了该问题:

This answer from Google forums fixed the issue for me:

您是否在curl命令中的URL周围使用引号?因为如果不，并且您处于bash外壳中(如果您使用curl)，您实际上可能并没有发送& ends_at = THEEND部分，因为&是一个shell元字符，用于将命令放入背景.

Are you using quotes around the URL in your curl command? Because if not, and you're in a bash shell (which is pretty likely if you're using curl), you might not actually be sending the &ends_at=THEEND part, because & is a shell metacharacter to put the command in the background.
