无法使用 Swagger-UI 的 jar 文件调用 API

Question

我使用 http://swagger.io/ 生成了我的类，我得到了包含类和模型的 zip 文件。

当我编译一个 jar 文件然后将它作为 jar 库添加到我的项目时，它给我这个错误：

这是 swagger 生成库的 build.gradle 文件：

    group = 'io.swagger'
project.version = '1.0.0'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.+'

        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'

    }
}

allprojects {
    repositories {
        jcenter()
    }
}


apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'

android {
    compileSdkVersion 22
    buildToolsVersion '23.0.2'

        targetSdkVersion 23
    }
    compileOptions {

    }

    // Rename the aar correctly
    libraryVariants.all { variant ->
        variant.outputs.each { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.aar')) {
                def fileName = "${project.name}-${variant.baseName}-${version}.aar"
                output.outputFile = new File(outputFile.parent, fileName)
            }
        }
    }
}

    }
    testCompile "junit:junit:$junit_version"
}

afterEvaluate {
    android.libraryVariants.all { variant ->
        def task = project.tasks.create "jar${variant.name.capitalize()}", Jar
        task.description = "Create jar artifact for ${variant.name}"
        task.dependsOn variant.javaCompile
        task.from variant.javaCompile.destinationDir
        task.destinationDir = project.file("${project.buildDir}/outputs/jar")
        task.archiveName = "${project.name}-${variant.baseName}-${version}.jar"
        artifacts.add('archives', task);
    }
}

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier = 'sources'
}

artifacts {
    archives sourcesJar
}

有人可以帮忙吗？

如果您尝试从 Swagger-Editor 生成默认模板，您将获得 apache http 版本。

克隆 Swagger-Codegen project from github，按照说明使用 volley、okhttp-gson、retrofit 等制作客户端。

更新

要生成 Android Volley 客户端：

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i <your_path_to_swagger.json> -l android --library=volley -o <output_path>

生成Javaokhttp-gson:

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i <your_path_to_swagger.json> -l java --library=okhttp-gson -o <output_path>

在这两种情况下，在生成项目后导航到项目文件夹，然后使用

mvn package

并且您将在 \target

上填充库 jar
