问题描述
在我的 Spring 应用程序中，我从用户那里获取一个 XML 文件，对其进行解析，然后以一种形式向用户显示值以生成许可证密钥。 HTML 是：
<h1 mat-dialog-title color="primary">Generate New License</h1>
<mat-dialog-content >
<div style="width:100%;display: flex;flex-direction: column;">
<mat-form-field>
<mat-label>Customer Name</mat-label>
<input matInput [(ngModel)] = "data[0].customerName" type="text" id="customerName" name="customerName" placeholder="Enter the Customer Name">
<mat-error *ngIf="submitted && hasError('customerId','required')">Enter the Customer Name</mat-error>
</mat-form-field>
<mat-form-field>
<mat-label>Email</mat-label>
<input matInput [(ngModel)] = "data[0].emailAddress" type="text" id="emailAddress" name="emailAddress" placeholder="Ex.: johndoe@abc.com">
<mat-error *ngIf="submitted && hasError('emailAddress','required')">Enter the E-Mail <Address></Address></mat-error>
</mat-form-field>
<mat-form-field>
<mat-label>Phone Number</mat-label>
<input matInput [(ngModel)] = "data[0].phoneNumber" type="text" id="phoneNumber" name="phoneNumber" placeholder="Enter the Phone Number">
<mat-error *ngIf="submitted && hasError('phoneNumber','required')">Enter the Phone Number</mat-error>
</mat-form-field>
<mat-form-field>
<mat-label>Hardware Key</mat-label>
<input matInput [(ngModel)] = "data[0].hardwareKey" type="text" id="hardwareKey" name="hardwareKey" placeholder="Enter the Hardware Key">
<mat-error *ngIf="submitted && hasError('hardwareKey','required')">Enter the Hardware Key</mat-error>
</mat-form-field>
<br>
<mat-form-field>
<mat-label>IP Address</mat-label>
<input matInput [(ngModel)] = "IpAddress" type="text" id="IpAddress" name="IpAddress" placeholder="Enter IP Address">
<mat-hint>Enter valid IP Address only</mat-hint>
</mat-form-field>
<br>
<br>
<strong>* Default Expiration Date for all licenses is 01/01/2100 *</strong><br>
<br>
</div>
</mat-dialog-content>
<br><br>
<mat-dialog-actions align="end">
<button mat-button mat-raised-button color="primary" (click)="generateLicense()">SUBMIT</button>
<button mat-button mat-raised-button color="primary" type="reset">RESET</button>
<button mat-button mat-raised-button color="warn" mat-dialog-close cdkFocusInitial >CLOSE</button>
</mat-dialog-actions>
<br>
<mat-form-field class="generate-full-width">
<input matInput [readonly]="!editable" id="scrollmenu" style="margin-left:200px" placeholder="License Key" style="font-weight: bold;" value={{this.LicenseKey}}>
</mat-form-field><br><br>
<button type="button" style="margin-left:200px" (click)="copyLicensetoClipboard(this.LicenseKey)" class='btn btn-primary'>copy License Key</button>
点击提交生成许可证密钥。 component.ts 是：
export class LicenseXmlDialog implements OnInit {
editable: boolean = false;
LicenseKey: string = "";
form: FormGroup;
submitted: boolean = false;
matcher = new MyErrorStateMatcher();
minDate = new Date();
constructor(
private fb: FormBuilder,public dialogRef: MatDialogRef<LicenseXmlDialog>,private generateLicenseService: GeneratelicenseService,@Inject(MAT_DIALOG_DATA) public data) {
}
ngOnInit() {
this.form = this.fb.group({
hardwareKey: ['',Validators.required],IpAddress: ['',emailAddress: ['',phoneNumber: ['',customerId: ['',expirationDate: [''],});
}
generateLicense() {
this.submitted= true;
const { value,valid } = this.form;
let hardwareKey = this.data[0].hardwareKey;
let IpAddress = this.form.value.IpAddress
let emailAddress = this.data[0].emailAddress;
let phoneNumber = this.data[0].phoneNumber;
let customerId = this.data[0].customerName;
let expirationDate = JSON.parse(JSON.stringify("Friday,1 January 2100 05:30:00 GMT+05:30"));
this.generateLicenseService.newLicense(hardwareKey,IpAddress,emailAddress,phoneNumber,customerId,expirationDate)
.subscribe((data) => {
console.log(data["LicenseKey"])
this.LicenseKey = data["LicenseKey"];
})
console.log(value)
if (valid) {
//this.dialogRef.close(value);
this.form.reset();
}
}
// validation for input fields
public hasError = (controlName: string,errorName: string) => {
return this.form.controls[controlName].hasError(errorName);
}
当我单击提交时，会生成许可证密钥，但 IP 地址为空或空。我解密了许可证密钥，并为此使用了 console.log。 XML 文件永远不会有 IP 地址。我该怎么做才能从 XML 获取其他值，但 IP 地址作为用户输入。由于 nngModel 和 formCntrolName 不能一起工作，我该如何规避这个问题？
