fetch

问题 I'm using fetch.js (https://github.com/github/fetch) to send a relatively large json object to the backend. The json is large in that it include an SVG image string. I'm not clear if fetch.js is using gzip compression by default, or if I need to manually compress and add headers. Any help would be appreciated. return new Promise((resolve, reject) => { fetch(api_base + "/api/save-photo", { method: 'POST', mode: 'cors', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify

问题 I'm working in React Native , I use PHP for backend and when I use fetch POST request I get so strange error, and I dont know why it happens. I checked the url so it works no problem, also normal fetch() is working without POST but when I try to post it happens. When I try it in local server fetch POST works.. but in server, I get this error : ERROR : com.facebook.react.bridge.ReadableNativeMap cannot be cast to java.lang.String React native codes : fetch('http://xxx/react_test1', { method:

问题 When use fetch for request in server using headers return SyntaxError: Unexpected end of input at index.js:50 at <anonymous> Line of code 50 is }).then(res => res.json()) What can be wrong? This code fetch. fetch(api-url, { mode: 'no-cors', method: "POST", headers: { 'Accept': 'application/json', 'Content-Type': ' application/json', 'X-API-SERVER': '85499f9f' }, }).then(res => res.json()) .then(res => { if (res.status === 200){ console.log("accepted"); }else { console.log(res.error); }

问题 I trying to use fetch for calls to backend from react without libs like Axios. api.ts export const sendSuggestion = ((data: any): Promise<any> => { console.log(JSON.stringify(data)); const apiUrl = `/api/suggest/`; return fetch(apiUrl, { method: 'POST', headers: {'Content-Type': 'application/json'}, body: JSON.stringify(data) }).then(checkStatus) .then(r => r.json()) .then(data => { console.log(data); }); }); const checkStatus = ((response: any) => { if (response.ok) { return response; } else

问题 I'm using a React web app and trying to upload a file to AWS S3. I've tried everything both locally ( localhost:3000 ) and when deployed to production (Vercel serverless functions). I first use a fetch to retrieve a presigned url for the file upload, which works perfectly: module.exports = async (req, res) => { let {fileName, fileType} = req.body; const post = await s3.createPresignedPost({ Bucket: BUCKET_NAME, Fields: { key: fileName }, ContentType: fileType, Expires: 60 }); res.status(200)

问题 I am trying to import a json file using Fetch() to populate multiple Google sheets I have been trying for a few hours but I do not know enough to do this The json is dynamic so its data is always changing but its structure remains the same my json looks like { "connections": [ { "Id": 131527, "From": 49647, "To": 49644, "Name From": "Horus Max", "Name To": "Bob allison", "Initial Date": "9/21/2020 15:20", "Last Date": "9/21/2020 15:20", "Type": "", "Weight": 0, "Checkbox ZZZ": "", "Text Area"
