我已经按照npm包文档的建议写了一个Axios POST请求,比如:
var data = {
'key1': 'val1',
'key2': 'val2'
}
axios.post(Helper.getUserAPI(), data)
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
它工作,但现在我已经修改了我的后端API接受头文件。
内容类型:“application / json”
授权:“JWT fefege…”
现在,这个请求在Postman上工作得很好,但在编写axios调用时,我遵循了这个链接,但不能完全使其工作。
我经常得到400坏请求错误。
这是我修改后的请求:
axios.post(Helper.getUserAPI(), {
headers: {
'Content-Type': 'application/json',
'Authorization': 'JWT fefege...'
},
data
})
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
我们可以将头信息作为参数传递,
onClickHandler = () => {
const data = new FormData();
for (var x = 0; x < this.state.selectedFile.length; x++) {
data.append("file", this.state.selectedFile[x]);
}
const options = {
headers: {
"Content-Type": "application/json",
},
};
axios
.post("http://localhost:8000/upload", data, options, {
onUploadProgress: (ProgressEvent) => {
this.setState({
loaded: (ProgressEvent.loaded / ProgressEvent.total) * 100,
});
},
})
.then((res) => {
// then print response status
console.log("upload success");
})
.catch((err) => {
// then print response status
console.log("upload fail with error: ", err);
});
};
如果你正在使用vuejs原型中的一些属性,在创建时不能读取,你也可以定义头文件并写入。
storePropertyMaxSpeed(){
axios
.post(
"api/property",
{
property_name: "max_speed",
property_amount: this.newPropertyMaxSpeed,
},
{
headers: {
"Content-Type": "application/json",
Authorization: "Bearer " + this.$gate.token(),
},
}
)
.then(() => {
//this below peace of code isn't important
Event.$emit("dbPropertyChanged");
$("#addPropertyMaxSpeedModal").modal("hide");
Swal.fire({
position: "center",
type: "success",
title: "Nova brzina unešena u bazu",
showConfirmButton: false,
timer: 1500,
});
})
.catch(() => {
Swal.fire("Neuspješno!", "Nešto je pošlo do đavola", "warning");
});
};
