您好我在angular 2应用程序中上传了多个文件,如下所示
UploadFile(requestParams: any, files: Array<File>) {
console.log(requestParams, 'rquest came');
const dataUrl = `/Myproject/uploadDocuments`;
console.log(dataUrl, 'posting url');
return Observable.fromPromise(new Promise((resolve, reject) => {
let formData: any = new FormData(),
xhr = new XMLHttpRequest();
formData.append('applicationId', requestParams.applicationId ? requestParams.applicationId : requestParams);
formData.append('documentType', 'bestQuote');
formData.append('user', requestParams.user ? requestParams.user : null );
for (let i = 0; i < files.length; i++) {
console.log(i, files[i], 'each file contains');
formData.append('uploadDocumentList[]', files[i], files[i].name);
}
xhr.setRequestHeader('Content-Type', 'multipart/form-data');
xhr.setRequestHeader('Accept', 'application/pdf');
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
console.log(JSON.parse(xhr.response), 'upload response');
resolve(JSON.parse(xhr.response));
} else {
reject(xhr.response);
}
}
};
xhr.open('POST', dataUrl, true);
xhr.send(formData);
}));
}
在我的一个组件中,一旦用户输入密码并上传文件,就将密码添加到文件对象中,如下所示
onPasswordChange(event: any, file: any) {
let password = event.target.value;
this.fileList.map(obj => {
if (obj.name === file.name) { obj.password = password; }
});
}
但有些如何在后端方面附加密码没有得到。伙计们谁有任何线索在这里出错?在控制台console.log(i, files[i], 'each file contains');
中,我可以清楚地看到我的密码已成功通过。但在后端方面它没有得到。有什么想法会出错吗?在此先感谢:)
