During the server-side automated testing process, the content-type in the request header corresponding to the file upload type interface is multipart/form-data; boundary=..., when encountering this type of interface, use Java's REST Assured or Python's Requests can be resolved.
Combat practice
Python version
In the Python version, you can use the files parameter to upload files. files requires the parameter content to be passed in dictionary format, the key value is the name of the uploaded file, and the value usually requires a binary mode file stream to be passed.
url = 'https://httpbin.ceshiren.com/post'
files = {"hogwarts_file": open("hogwarts.txt", "rb")}
r = requests.post(url, files=files)
r.text
{
"args": {},
"data": "",
"files": {
"hogwarts_file": "123"
},
"form": {},
...省略...
"url": "https://httpbin.ceshiren.com/post"
}
java version
Java needs to use the multiPart() method provided by the given() method. The first parameter is name, and the second parameter needs to pass a File instance object. During the File instantiation process, the absolute path + file name of the uploaded file needs to be passed in. .
import java.io.File;
import static io.restassured.RestAssured.*;
public class Requests {
public static void main(String[] args) {
given().multiPart("hogwartsFile", new File("绝对路径+文件名")).
when().post("https://httpbin.ceshiren.com/post").then().log().all();
}
}
The response content is
{
"args": {
},
"data": "",
"files": {
"hogwarts_file": "123"
},
"form": {
},
"headers": {
...省略...
},
"json": null,
"origin": "119.123.207.174",
"url": "https://httpbin.ceshiren.com/post"
}
Use the packet capture tool to grab the process data, and you can clearly see that in the process of transferring data, if it is the Java version, the content of the name transfer is the first parameter of the multiPart() method, and in the Python version, the key of the dictionary passed as the files parameter value, and whether filename is the Java version or the Python version, the passed content is the file name of the passed file.
