[英]Upload a file from react native image picker to server
有人能告诉我我做错了什么我不断收到错误 400 错误请求,我似乎无法弄清楚如何发送图像我试图发送路径、文件名和 mime 但它不起作用这是我的请求:
const [image,setImage]=useState(null) const[filename,setFileName]=useState(null) const sendpic=async ()=>{ await ImagePicker.openCamera({ mediaType:'photo', width: 300, height: 400, cropping: false, }).then(image => { setImage(image['path']); const paths=image['path'] const filename=paths.substring(paths.lastIndexOf('/')+1); setFileName(filename); console.log(filename) console.log(image) const data=new FormData(); data.append('image',filename) data.append('title','3aslemajiti') const headers={ Accept:'application/json', 'Content-Type':'multipart/form-data', } try{ const response= axios.post('http://192.168.1.19:8000/Sends/',data,{headers:headers}) alert('yess!!!!!'); } catch (error) { // handle error alert(error.message); } }); };
这是我的模型:
from django.db import models # Create your models here. class Send(models.Model): title = models.CharField(max_length=255) image=models.ImageField(default ='null') def __str__(self): return self.title
我如何编写请求以使其被服务器接受?
data.append('image', {
uri: filename,
name: 'test.jpg',
type: 'image/jpeg'
});
图片上传格式应该是这个,请检查文件 url 是否正确。
"uri": "file:///Users/user/Library/Developer/CoreSimulator/Devices/33198C8D-55D3-4555-B9B5-DC1A61761AAF/data/Containers/Data/Application/B5067299-1CD2-4000-8936ED-497B tmp/871EB6D5-2408-4A10-8DE7-EE52B1855ECD.jpg"
这是图片的网址。 它应该是这样的。
const data = new FormData();
data.append("uploadFile", {
name: filename,
type: filetype,
uri:
Platform.OS === "android"
? fileuri
: fileuri.replace("file://", "")
});
var url = uploadDoc
axios.post(url, data, {headers: {
"Content-Type": "multipart/form-data",
Accept: "application/json",
Authorization: authToken
}})
.then((res) => {
})
.catch((err) => {
})
