上载到imgur时出错（格式错误的身份验证标头）

Question

我试图使用Imgur上传一些图像在一个角Web应用程序，但一直得到"畸形的认证头"，有人知道如何修复这个错误吗？

async uploadImage(imageFile: File, infoObject: {}, categoryId) {
        const formData = new FormData();
        formData.append('image', imageFile, imageFile.name);

        const header = new HttpHeaders(`Authorization: Client-ID xxxxxxxxxxx`);
        const imageData = await this.http.post(this.url, formData, {headers: header}).toPromise();
        this.imageLink = imageData['data'].link;

        const newImageObject: ImageInfo = {
          title: infoObject['title'],
          description: infoObject['description'],
          link: this.imageLink
        };
        this.images.unshift(newImageObject);
        this.updateCategoryImgIconPath(categoryId, this.imageLink).subscribe(data => window.location.reload());
    }

在Angular中设置HttpHeaders的正确方法是这样的：

const header = new HttpHeaders().set('Authorization', 'Client-ID xxxxxxxxxxx');
