I try to send my Image from react-native to my database.
it sends my image's base64 code. However, base64 code is too long so my webservice doesnt take all of them. How can I send it ?
This is what I tried :
selectPhoto = () => {
const options = {};
ImagePicker.showImagePicker(options, response => {
if (response.uri) {
this.setState({ data: response.data });
}
});
}
sendImage() {
fetch('url', {
method: 'POST',
headers: new Headers({
Accept: 'application/json',
'Content-Type': 'application/json', // <-- Specifying the Content-Type
}),
body: JSON.stringify(this.state.data), // data has base64 code
})
}

When I call API I am getting below error in response. please find below is code and error message.
TEST RESPONSE:
{
"responseData": {"limit": ["Limit is required"],
"module_type": ["Module type required"],
"section": ["section value \"liveability || investment || recommend\" is required"],
"skip": ["Skip is required"]
}
Implemented code:
fetch( 'https://api.dotcomkart.com/api/homePagePropertyList?', {
method: 'POST',
body: JSON.stringify({
skip: 0,
limit: 10,
module_type:'buy',
section: 'liveability'
}),
})
Try this way
import FormData from 'FormData';
...
var data = new FormData();
data.append("skip", "0");
data.append("module_type", "buy");
....
fetch('YOUR_URL', {
method: 'POST',
headers: {
Accept: 'application/json',
'Content-Type': 'multipart/form-data',
},
body: data,
})
.then((response) => response.json())
.then((responseJson) => {
console.log('response object:',responseJson)
})
.catch((error) => {
console.error(error);
});
Sometimes when you work with REST API call you have to work with correct headers.
In your case I suppose your are missing two important headers required to activate a good communication between client and servers:
accept
content-type
Please review your code based on this one:
fetch('https://api.dotcomkart.com/api/homePagePropertyList?', {
method: 'POST',
headers: {
"accept": "application/json",
"content-type": "application/json"
},
body: JSON.stringify({
skip: 0,
limit: 10,
module_type:'buy',
section: 'liveability'
}),
})
I think the server is returning "missing" parameters because is not able to understand the type of content. With Content-Type you should be able to instruct the server on how to parse your data.
I'm trying send a post request using axios to my backend but I can't send the boolean "isActive" for some reason. Is there a way to do this?
async submit() {
const isValid = await this.$validator.validateAll()
if (isValid && !this.submitting) {
let formData = new FormData();
formData.set("city", this.formData.city)
formData.set("state", this.formData.state)
formData.set("county", this.formData.county)
formData.set("isActive", true) // <- NOT ACCEPTING THIS VALUE
axios.post("/api/v1/team/createTeam", formData, {
headers: {
'Content-Type': 'application/json'
}
})
.then(res => {
if (res.status === 200) {
this.submitting = true
this.cancelModal()
} else {
console.log(res.data.code);
}
})
.catch(function (err) {
console.log(err);
})
}
}
FormData can only contain string values. Setting a Boolean true would result in "true" for the value. The backend would have to convert that string to a Boolean.
Also, your header should not be application/json (intended for JSON payloads). If sending FormData as the payload, the header should be multipart/form-data:
axios.post("/api/v1/team/createTeam", formData, {
headers: {
'Content-Type': 'multipart/form-data'
}
})
If your backend is actually expecting JSON, then you can't send FormData. Switch to a JavaScript object instead (which does accept Booleans):
const payload = {
city: this.formData.city,
state: this.formData.state,
county: this.formData.county,
isActive: true,
}
axios.post("/api/v1/team/createTeam", payload, {
headers: {
'Content-Type': 'application/json'
}
})
As i am trying to send my data in form of body in backed url as in backed i have made something if it dont receive body it will send sucess: false, msg: haven't received body else sucess: true, msg: jwt token as if i make request from post man with same data it's working but sending via. native app it fails to send.. any help will be helpfull
As 1st request is from postman and 2nd from my app
const handleLogin = (Enrno, Pass) => {
setError(null);
setIsLoaded(false);
setItems([]);
fetch(config.url + "/login", {
method: "POST",
header : {
Accept : 'application/json',
'Content-Type' : 'application/json'
},
body : JSON.stringify({
"enrno": Enrno,
"password" : Pass
})
})
.then((res) => res.json())
.then(
(result) => {
setIsLoaded(true);
setItems(result);
alert(items[0].msg);
},
(error) => {
setIsLoaded(true);
setError(error);
}
);
};
I think you need to put these to headers, not header.
Accept : 'application/json',
'Content-Type' : 'application/json'
So, it should look like this.
fetch(config.url + "/login", {
method: 'POST',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({
enrno: Enrno,
password : Pass
})
})
I want to upload a file using Axios but for that I need to use formData, my problem is that when I am using formData the data are not send at all.
Here is my code without formData, its working fine all the data are sent :
axios({
method: 'post',
url: jsonurl,
data: {
session_id: '123',
},
headers: {
'Content-Type': 'multipart/form-data',
}
})
.then((value) => {
console.log(value); // return in console : status 200 and config: data: session_id: "123" ...
})
.catch(err=>console.error(err));
Same code with formData (no data sent, $_GET['id'] doesnt exist) :
const formData = new FormData();
formData.append('session_id', '123');
axios({
method: 'post',
url: jsonurl,
formData,
headers: {
'Content-Type': 'multipart/form-data',
}
})
.then((value) => {
console.log(value); // return in console : status 200 but config: data: FormData {}
})
.catch(err=>console.error(err));
No data sent, return in console status 200 but config: data: FormData {} (so no data) and on backend $_POST['session_id'] doesnt exist, the form is sent (I get my jsonencode return) but there is no input data.
I dont catch any error either.
Finally I found the solution, my syntax was wrong, here is one who works :
var postResults = await axios.post(jsonurl,
formData,
{
headers: {
'Content-Type': 'multipart/form-data'
}
}
)
.then(function(value){
console.log(value);
return value;
})
.catch(function(error){
console.log(error);
});
I am waiting for successful JSON from server:
{"...."}
Actual Behavior
I get
SyntaxError: Unexpected token b in JSON at position 0
b is the first letter of word "badlogin". It responds server when sent wrong combination of userName and password. But when I use Postman with the same key values combination on the same address I get correct rosponse from the server.
Steps to Reproduce
fetch('http://....', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
userName: "react",
password: "123",
})
}).then((response) => response.json())
.then((responseJson) => {
console.log(responseJson.message);
if(responseJson.success === true) {
alert('successufuly loged');
}
else{
console.log(responseJson.message);
alert(responseJson.message);
}
})
}
}
You are trying to parse a string. This is the error. Instead of always parse the json, just add a clausule to check if the request was made with success
}).then((response) => {
if(!response.ok) {
// handle your error here and return to avoid to parse the string
return
}
return response.json()
})
.then()
Look like the response you got is not json
Try to check what is the response you are getting first:
.then((response) => response.text())
.then((responseJson) => {
console.log(responseJson);
}
I solved this issue by using FormData to prepare data for sending:
......
login = () => {
var formData = new FormData();
formData.append('username', 'react');
formData.append('password', '123');
fetch('http://......', {
method: 'POST',
body: formData
........
