在请求库中传递curl -d参数时出错 [英] Error passing curl -d parameter in requests library

问题描述

我有一个 curl POST请求，该请求在终端机(macOS)中运行良好，并按预期返回了csv.RJMetrcis 文档中提供了以下格式(请参见导出"数字数据").这是bash中的curl请求:

I have a curl POST request that works perfectly in the terminal (macOS), returning a csv as expected. The following format is provided in the RJMetrcis documentation (see "Export figure data"). Here is the curl request in bash:

 curl -d "format=csv&includeColumnHeaders=1" -H "X-RJM-API-Key: myAPIkey" https://api.rjmetrics.com/0.1/figure/0000/export

我的目标是使用 requests 在Python中实现 exact 相同的curl请求.当我输入与POST请求相同的参数时，代码不起作用并返回错误:

My objective is to implement the exact same curl request in Python using requests. When I input the same parameters as a POST request, the code does not work returning an error:

import requests


headers = {'X-RJM-API-Key: myAPIkey'}
data= {'format=csv&includeColumnHeaders=1'}
url = "https://api.rjmetrics.com/0.1/figure/0000/export"

response = requests.post(url, data, headers)

这将返回错误:

TypeError: memoryview: a bytes-like object is required, not 'str'

第二次尝试:

response = requests.post(url, data=data, headers=headers)

返回

AttributeError: 'set' object has no attribute 'items'

在python中构造POST请求的正确格式是什么，以使其符合 data = {'key':'value'} 约定并返回csv?将bash curl POST转换为python POST请求

What is the correct format in python for constructing a POST request so that it matches the data = {'key':'value'} convention, and returns a csv?Any help would be appreciated translating the bash curl POST into a python POST request

推荐答案

在这里您传递了一个集合，并且希望传递dict或str对象

Here you are passing a set and you are expected to pass a dict or str object

data= {'format=csv&includeColumnHeaders=1'}

替换为

data= {'format':'csv&includeColumnHeaders=1'}

应该修复它.

另一方面，看到您的卷曲请求.

On the other hand by seeing your curl request..

这完全取决于您要如何传递数据，以下代码(将数据有效载荷作为字符串传递)将直接发布数据，这等效于curl中的--data-raw

It all depends how you want to pass the data, following code (passing the data payload as a string) will post the data directly, that will be the equivalent to --data-raw in curl

import requests

url = "https://api.rjmetrics.com/0.1/figure/0000/export"

payload = "'{\"format\":\"csv&includeColumnHeaders=1\"}'"
headers = {
  'X-RJM-API-Key': 'myAPIkey'
}

response = requests.request("POST", url, headers=headers, data = payload)

print(response.text.encode('utf8'))
