Today, the editor will share with you the relevant knowledge points about how to realize the file upload / download interface automation of the Python interface. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

0. Preface

The file upload / download interface is similar to the normal interface, but with slight differences.

If you need to send files to the server, such as uploading documents, pictures, videos, etc., you need to send binary data. Files are usually uploaded using Content-Type: multipart/form-data data type. You can send files or relevant message body data.

File download, on the other hand, stores the response content in binary format locally and writes the file name according to the format of the file you need to download, for example: Faffle / contract file .pdf.

1. File upload interface 1. Interface document

Request URL: / createbyfile

Request Method: POST

Content-Type: multipart/form-data

Whether the name type must describe whether fileFile is a document file titleString is a document name fileTypeString is a file type: doc, docx, txt, pdf, png, gif, jpg, jpeg, tiff, html, rtf, xls, txt2. Code implementation

(1) implementation steps:

Construct the file data and open the file in a binary way through the open function

The parameters of the file upload interface, like ordinary post requests, need to be written in Key and Value modes. Key is the parameter name file (which is also the name attribute of the component), and Value is a tuple (different from the normal API).

"file": (",", the first value of # tuple is the file name. If not, take None open (r "F:\ pdf_file.pdf", "rb"). # if the first value is not None, take the binary stream opened by the file open, otherwise write the file path directly. For example, "F:\ pdf_file.pdf"pdf" # file type) "file": (None, "F:\ pdf_file.pdf")

Construct other data

{"title": "documentation initiated by API", "fileType": "pdf"}

Send the request, pass in the file data as files parameter, and other message body data through data, json, headers, cookies, etc.

Req = {"url": "127.0.0.1/v2/document/createbyfile", "method": "POST", "headers": {}, "files": {"file": (", open (r" F:\ pdf_file.pdf "," rb ")," pdf ")} "data": {"title": "documentation initiated by API", "fileType": "pdf"}}
