python将字典的文字值分配给另一个字典的键 [英] python assign literal value of a dictionary to key of another dictionary
问题描述
我正在尝试为特定的请求正文形成Web有效负载，但无法正确处理.我需要的是传递我的身体数据，如下所示
I am trying to form a web payload for a particular request body but unable to get it right. What I need is to pass my body data as below
data={'file-data':{"key1": "3","key2": "6","key3": "8"}}
我完整的有效负载请求看起来像这样
My complete payload request looks like this
payload={url,headers, data={'file-data':{"key1": "3","key2": "6","key3": "8"}},files=files}
但是，当我通过此操作时，python会尝试解析每个单独的键值，并像这样将其分配给文件数据"键
However, when I pass this, python tries to parse each individual key value and assigns to the 'file-data' key like this
file-data=key1
file-data=key2
file-data=key3
，依此类推，对于我在嵌套字典中传递的尽可能多的键而言.但是，要求是将整个字典作为这样的文字内容传递((不按每个键拆分值):
and so on for as many keys I pass within the nested dictionary. The requirement however, is to pass the entire dictionary as a literal content like this(without splitting the values by each key):
file-data={"key1": "3","key2": "6","key3": "8"}
因此，理想的HTTP跟踪在理想情况下应如下所示:
The intended HTTP trace should thus ideally look like this:
POST /sample_URL/ HTTP/1.1
Host: sample_host.com
Authorization: Basic XYZ=
Cache-Control: no-cache
Content-Type: multipart/form-data; boundary=----UVWXXXX
------WebKitFormBoundaryXYZ
Content-Disposition: form-data; name="file-data"
{"key1": "3","key2": "6","key3":"8" }
------WebKitFormBoundaryMANZXC
Content-Disposition: form-data; name="file"; filename=""
Content-Type:
------WebKitFormBoundaryBNM--
因此，我想将此作为POST请求(使用python请求库)的有效负载的一部分.任何建议都将受到感激-
As such, I want to use this as part of a payload for a POST request(using python requests library). Any suggestions are appreciated in advance-
Edit1 :为了提供更多的清晰度，API定义是这样的:
Edit1: To provide more clarity, the API definition is this:
Body
Type: multipart/form-data
Form Parameters
file: required (file)
The file to be uploaded
file-data: (string)
Example:
{
"key1": "3",
"key2": "6",
"key3": "8"
}
我使用的python代码段(检查建议后的 )是这样的:
The python code snippet I used(after checking suggestions) is this:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import requests
url = "https://sample_url/upload"
filepath='mypath'
filename='logo.png'
f=open(filepath+'\\'+filename)
filedata={'file-data':"{'key1': '3','key2': '6','key3': '8'}"}
base64string = encodestring('%s:%s' % ('user', 'password').replace('\n', '')
headers={'Content-type': 'multipart/form-data','Authorization':'Basic %s' % base64string}
r = requests.post(url=url,headers=headers,data=filedata,files={'file':f})
print r.text
我现在得到的错误仍然与下图相同:
The error I get now is still the same as shown below:
{"statusCode":400,"errorMessages":[{"severity":"ERROR","errorMessage":"An exception has occurred"]
它还说某些条目丢失或不正确.请注意，在二进制模式下打开文件参数后，我也尝试传递文件参数，但它会抛出相同的错误消息
It also says that some entries are either missing or incorrect. Note that I have tried passing the file parameter after opening it in binary mode as well but it throws the same error message
我也通过python打印了HTTP跟踪，它看起来像这样:
I got the HTTP trace printed out via python too and it looks like this:
send: 'POST sample_url HTTP/1.1
Host: abc.com
Connection: keep-alive
Accept-Encoding: gzip,deflate
Accept: */*
python-requests/2.11.1
Content-type: multipart/form-data
Authorization: Basic ABCDXXX=
Content-Length: 342
--CDXXXXYYYYY
Content-Disposition:form-data; name="file-data"
{\'key1\': \'3\',\'key2\': \'6\'
,\'key3\': \'8\'}
--88cdLMNO999999
Content-Disposition: form-data; name="file";
filename="logo.png"\x89PNG\n\r\n--cbCDEXXXNNNN--
推荐答案
如果要发布带有Python请求的 JSON ，则应不使用data，但json:
If you want to post JSON with python requests, you should NOT use data but json:
r = requests.post('http://httpbin.org/post', json={"key": "value"})
由于您的示例，我只能猜测您正在使用data
I can only guess that you are using data because of your example
payload={url,headers, data={'file-data':{"key1": "3","key2": "6","key3": "8"}},files=files}
这不是有效的python语法.
Whis is not valid python syntax btw.
