错误：

    "status": 400,
    "traceId": "00-415d71c9881187498929206abd2ec4ab-9f31d5c108f99944-00",

        "": ["Failed to read the request form. Unexpected end of Stream, the
 content may have already been read by another component. "]

【问题讨论】：

从使用 Python Requests 模块开始工作。然后，您应该几乎可以替换掉 Locust 客户端了。

标签： python performance-testing multipartform-data locust

【解决方案1】：

import requests
from requests_toolbelt.multipart.encoder import MultipartEncoder
import json

multipart_data = MultipartEncoder(
fields={
    # a file upload field
    'file': ('lookup.csv', open(r'C:\Perffiles\lookup.csv', 'rb'), 'text/plain'),
    # plain text fields
    'blobText': '{ ID: 3, FileClass: "LogicsticsConstraints", FileDescriptor: "test", 
      FieldName: "aep_lookup -test1.csv" }'
    }
    )

  urlupload = "https://1.2.3.4/api/v1/FileUpload/Upload"
 headersc = {'content-type': multipart_data.content_type,
        'Host': '1.2.3.4', 'Accept': '*/*'}
response = requests.request("PUT", urlupload, headers=headersc, data=multipart_data, verify=False)

也许你正在使用 FastHTTPUser 解决这个问题
